CONSULTING ENGINEERS 701 DEXTER AVENUE NORTH SUITE 200 SEATTLE, WASHINGTON 98109 • (206) 284-0860 EXECUTIVE SUMMARY The City of Tukwila 1998 Water System Comprehensive Plan provides the City's water utility with long term planning strategies over six-year and twenty-year planning periods. The document has been prepared to meet the planning requirements of the Washington State Department of Health (DOH) and the Growth Management Act. A system overview describing each of the City's six pressure zones is provided in Chapter One. The interrelationship of each of the water system's critical components is illustrated in a system schematic which provides information regarding sources of supply, meters, control valves, reservoirs, and transmission line connectivity. In Chapter Two, future water demand is determined using existing water use records and population projections developed from Puget Sound Regional Council's (PSRC) Transportation Analysis Zone (TAZ) model data and Washington State Office of Financial Management (OFM) data. A system analysis in Chapter Three provides an evaluation of the water utility according to local, state, and federal requirements. Chapter Three also presents water quality data applicable to the Tukwila water system as well as to Seattle's system. A hydraulic model, including more than 300 pipes and 300 junction nodes, was used to develop water system improvement recommendations for supply, storage, and distribution improvements. Results and recommendations from this model are presented in Chapter Four. Chapter Five discusses applicable water conservation regulations and presents the City's past and present efforts in this regard. Future conservation plans and recommendations are made at the end of this chapter. Chapter Six summarizes recommended improvements for the City's water system based on previous chapters and also on the City's Six -Year Capital Facilities Plan as developed by the Public Works and Financing departments. Chapter Seven analyzes the City's past revenues and expenditures and projects future revenues and expenditures in the six-year planning horizon. Costs for proposed improvements are discussed herein and methods for financing proposed improvements are also presented. A separate Operations and Maintenance Plan has been prepared by the City, and the most recent copy is included as an Appendix of this document. Some of the most significant conclusions and recommendations presented in this Water System Comprehensive Plan are as follows: • Over seventy percent of water use within the City's service area is attributable to commercial and industrial customers. Lost and unaccounted for water within the City system has averaged about 20% over the past four years. This report recommends the City reduce lost and unaccounted for water to 15% or less by 2003. Recommendations for achieving this goal are presented in Chapters Five and Six. This report strongly recommends calibrating large meters on a more frequent basis E- 1 and purchasing a portable sonic flow meter to audit unmetered water use through fire suppression lines. • The City has sufficient capacity to meet anticipated average day demands and peak day demands under fireflow conditions throughout most of the City's service area. At this time, the reliability of the Seattle water supply system precludes the need for additional City storage. • The City incurs significant demand metering charges from Seattle based on 15 -minute peak purchases during the summer. In order to reduce these peak purchases and potentially eliminate all demand metering charges, this report recommends installing a variable frequency drive (VFD) on the low zone pumps. With VFDs, control of the low zone pumps can be accomplished in such a manner as to effectively utilize existing storage to satisfy peak demands. • The replacement of substandard and undersized water Eines is a significant portion of the City's planned improvements program. ].n order to increase the hydraulic capacity of the City's water system and reduce dead end mains, the City will replace 19,000 feet and 15,000 feet of pipe in the six- year and twenty-year planning horizon, respectively. • A financial analysis of the Six -Year Capital Facilities Plan indicates that planned improvements will impact existing rates by approximately $1.05/Month/ERU at the end of the six-year planning period. Rate increases resulting from these improvements will not be necessary until 2000. All projects will be financed on a pay-as-you-go basis, and debt service is not anticipated. • A continuous -monitoring chlorine analyzer should be installed at the North Hill Reservoir in order to monitor disinfectant residual at the outlet of the reservoir. • Potential annexation areas within the City limits include the residential areas of Riverton and Thorndyke on the City's west side and the Foster Point area of Tukwila currently served by King County Water District No. 125. The effects of these potential expansions on the City's water system must be examined prior to consolidation into the City system. A Water System Plan update should also be completed prior to any annexations.

Several areas within the City limits are served by local water districts, and many neighboring communities and cities have direct interties with the City's water system. Decisions and actions that affect the City's and neighboring community's utility operations and maintenance are coordinated through a collective organization known as the SKYWAY Water Utility Coordinating Committee (WUCC). Participating water purveyors include the cities of Tukwila, Seattle, and Renton; King County Water Districts (KCWD) Numbers 14, 20, 57, and 125; Highline Water District, the Skyway Water and Sewer District, and the Lakeridge Water District. The City's Washington State Department of Health (DOH) water system identification number is 89500F, and a copy of the Water Facilities Inventory (WFI) form is included in the Appendix. The City is governed by an elected Mayor and City Council. The City's current mailing address is: City of Tukwila 6200 Southcenter Blvd. Tukwila, WA 98188 A vicinity map showing the location of The City of Tukwila and the surrounding area is presented as Figure 1-1. SYSTEM BACKGROUND HISTORY OF WATER SYSTEM DEVELOPMENT AND GROWTH The City of Tukwila, which began as a small community centered around the Green River, became incorporated in 1908. At that time, the total area within city limits was approximately 418 acres of land. Drinking water at this time was supplied by several groundwater wells and the Green River. In 1929, the Tukwila Public Water System was formed, and a six-inch diameter steel water line was constructed to connect Seattle's Beacon Hill to Tukwila's North Hill area. During the late 1950s, the City annexed land that increased the City's area to 1,739 acres for a population of approximately 800 people. Minor annexations shortly after this added another 1,000 acres of land within the City limits. In 1964, federal funds were acquired by Tukwila through a local improvement district (LID), and major improvements and additions were made to the existing water distribution system. 1-1 CLALLAM it I WHATCOM SNOHOMISH CHELAN JEFFERSON GRAYS HARBOR KITTITAS TH PACIFIC %WAHKIAKUM YAKIMA 0 KLICKITAT CITY OF TUKWILA FIGURE 1-1 VICINITY MAP CONSULnNG ENINEERS Another wave of annexations in 1989 nearly doubled the City's land area to 5,513 acres and tripled population from 4,760 to 14,631 people at this time. Annexed areas from this time added land to the north of the existing City Limits including the Foster, Thorndyke, Cascade View, Riverton, and Fire District No. 1 areas. Drinking water in these regions was supplied by various water districts and public utilities before being annexed by the City. Since the annexation, the City has taken over some of the water services for areas within the City limits, and has entirely taken over the distribution system of King County Water District (KCWD) No. 25 within the City's corporate limits. Approximately 70 percent of the distribution system in this area has been replaced using City design and construction standards. The City's service area is currently supplied entirely from the City of Seattle's water system through a long term purveyor's contract. Surrounding water districts also have similar arrangements with the City of Seattle, and interties and agreements are maintained by several of these water districts with each other and with the City of Tukwila. Some of these water districts are also serving customers within Tukwila's corporate limits, and some of them have been taken over by the City of Tukwila. GEOGRAPHY The City of Tukwila is located in southwest King County, directly south of the City of Seattle. Tukwila is bordered by the City of Seattle to the north; the City of Renton to the east; the City of Kent to the south; and the City of Seatac to the west. The City limits are approximately defined by the BNSF Burlington Northern Railroad tracks on the east; Military Road S., Pacific Highway S., and the Duwamish River on the west; S. 180th Street on the extreme south end; and S. Kenyon Street projected across Boeing Field on the north. The topography within the City's service area varies from lowlands surrounding the Green and Duwamish River valleys to plateaus above the river valley walls. Steep slopes between these areas can vary from 15 to 70 percent and tend to be unstable. Elevations within the service area vary between just above sea level to over 300 feet. These elevation differentials have created the need for many pressure zones within the City's service area as well as for pressure reducers on individual services at lower elevations. ADJACENT PURVEYORS As mentioned above, several water districts are currently serving customers within the City's corporate limits. These include King County Water District (KCWD) 20 and 125 and Highline Water District. KCWD 25 and the Creston Water Association were both taken over by the City of Tukwila after their service areas were encompassed by the City's corporate limits. KCWD 25 served less than 500 connections within what is now the Allentown area of Tukwila, and the Creston Water Association served less than 100 customers in the Ryan Hill area of the City. Highline Water District also serves customers within the City of Tukwila's service area, namely in the Segale Park area and the Crystal Springs area in the southern portion of the City. KCWD 125 serves customers within the City of Tukwila's service area as well as 1-3 customers within the City limits of neighboring Seatac. Within the City of Tukwila, KCWD 125 serves customers in the Riverton and Foster districts. KCWD 20 serves only a few customers in the Riverton area, just north of KCWD 125 custorners. The service areas of the adjacent purveyors are shown on Figure 1-5. INVENTORY OF EXISTING FACILITIES SOURCE OF SUPPLY The City of Tukwila's water supply system is served entirely through interties with the City of Seattle's water transmission mains. The City of Tukwila maintains a long term purveyor's contract with Seattle which guarantees Tukwila a reliable, constant supply of safe drinking water. In exchange, Tukwila is committed to purchasing 100 percent of its water from Seattle until the year 2012. Tukwila has seven supply taps on three of Seattle's transmission mains, all of which use pressure reducing valves (PRVs) to decrease pressures from the Seattle mains. The PRVs vary in size from six-inch to twelve -inch, and are all maintained by Tukwila. City of Seattle Major System Facilities The Seattle water system is governed by the recently formed Seattle Public Utilities (SPU), which is responsible for delivering and selling water to both City of Seattle customers and many other cities and water districts in the Puget Sound area. Approximately 70 percent of the Seattle water supply comes from the Cedar River watershed, about 40 miles east of Seattle in the foothills of the Cascade mountains. The other 30 percent comes from the South Fork of the Tolt River just east of Carnation, in the Cascade foothills. Tukwila's water supply comes from the Cedar River transmission lines. Raw water is diverted from the Cedar River at Landsburg where it is chlorinated and fluoridated. Treated water is then conveyed through two 78 -inch steel supply lines and into the Lake Youngs regulating basin east of Renton (overflow elevation of 493 feet). Water is treated with lime for corrosion control and chlorine for disinfection prior to customer delivery. Four high pressure transmission mains, known as the Cedar River Pipelines, then bring water to the Puget Sound area. Cedar River Pipeline 4 (CRPL 4) separates from the other three pipelines and runs through the southern portion of Tukwila enroute to the Riverton area. A 48 -inch steel main branches off from CRPL 3 just east of the City and runs through the northern part of the City enroute to the City of Seattle's West Seattle Reservoir. This transmission line is called the West Seattle Pipeline (WSPL). Seattle and Tukwila's major water system facilities are shown in Figure 1-2. All of the Cedar River transmission lines run at the same hydraulic grade line (HGL) of approximately 465 feet mean sea level (MSL), although this can vary by as much as 30 feet depending on upstream demand conditions and the level of Lake Youngs. 1-4 EDMONDS nZ DUVALL TOLT RIVER PIPELINE rr",r ND nN/GIP RSF!E'.

The City's water supply is obtained from Seattle Public Utilities, who have filed a water right claim with DOE on the Cedar River and its watershed area in the Cascade foothills. This water right claim is summarized in Chapter 5. STORAGE In 1991, the City of Tukwila constructed the North Hill Reservoir and Pump Station in an area where pressures have historically been low during peak demand times. The storage facility is an above ground, concrete reservoir with a capacity of two million gallons and an overflow elevation of 250 feet. The pumps at the reservoir are configured to supply the North Hill services as well as the services within the rest of the City. These are referred to as the High Zone and Low Zone Pumps, respectively. The North Hill Reservoir is also equipped with an emergency fire flow pump which is used to boost system pressures in either zone during fire fighting efforts. The North Hill pumps are further detailed in Chapter 3, System Analysis. The City relies on Seattle's storage and supply abilities for peak demands and fire flows. Although Seattle has adequate facilities for supplying Tukwila's peak demands, this method of operation results in frequent demand charges by Seattle. 1-6 WATER TREATMENT Since the City wholly relies on Seattle for water supply, no additional treatment is performed. As mentioned previously, Cedar River water is fluoridated and chlorinated at Landsburg and then treated at Lake Youngs with chlorine for disinfection and lime for pH control. Tukwila monitors for coliform and disinfectant residual as required by DOH regulations and has also completed sampling and testing for disinfection by-products and lead and copper in conjunction with Seattle's water quality testing laboratory. TRANSMISSION AND DISTRIBUTION SYSTEM According to the City's 1991 Water System Comprehensive Plan (WSCP), approximately 98 percent of the Tukwila Water Distribution System was comprised of ductile iron (DI) and cast iron (CI) pipe. Since the publishing of that document, many improvements have been made to the distribution system, including new ductile iron water mains in Ryan Hill and Allentown. These changes are included in this Plan's water distribution system basemap. PRESSURE ZONES The City of Tukwila operates six pressures zones within its water service area. The locations of these pressure zones are shown in Figure 1-3. The 360 Zone is the largest pressure zone and includes the area from Southcenter/Interurban to East Marginal Way. Water is supplied to this zone through PRVs from Supply Stations 10, 11, 13, 14, and 15. The 465 Upper Ryan Hill pressure zone includes the area approximately bounded by 51 Ave. S. on the east, 49 Ave. S. on the west, and Interstate -5 on the south. This pressure zone is served directly from Supply Station 169. Directly west of the 465 Zone is the 340 Lower Ryan Hill pressure zone. This zone is bounded on the west and south by Interstate 5, on the north by the City limits and on the east by 49 Ave. S. This pressure zone is served through a PRV from the Upper Ryan Hill pressure zone. The north end of the City comprises the 320 North Boeing Field pressure zone. This zone begins north of S. Norfolk St. and is bounded on the north, west, and east by the City limits. This zone is served from the 360 Zone through a sixteen -inch PRV and a four -inch PRV on the 18 -inch distribution line in E Marginal Way S. The 400 North Hill pressure zone is located in an area approximately in the middle of the City just east of the Thorndyke neighborhood and north of Highway 518. This zone is served by the North Hill Pump Station, which pumps from the North Hill Reservoir. To the southwest of North Hill, an area approximately north of the CRPL 4 and South of Highway 518 makes up the 380 Crystal Springs pressure zone. This zone is served through a PRV from Supply Station 16 and is isolated from the main 360 zone with a one way check valve. The City's six pressure zones are shown in Figure 1-3, Water System Pressure Zone Schematic. A schematic of the North Hill reservoir and pump station is presented as Figure 1-4. 1-7 JUL 07 1998 20' 26: 21 a H 0 O J a JUN 29 1998 10: 00: 17 NOV 24 1997 16: 07: 25 OPERATOR: YBP FILENAME: M:\TUKWILA\97794\FIG1-3.

Lao. ooN5uTNG ENGINEERS BOOSTER STATIONS The City operates a single booster pump station at the North Hill Reservoir. This facility has two Low Zone pumps, two High Zone pumps, and a single, high capacity fireflow pump. Since the overflow of the North Hill Reservoir is at 250 feet MSL, pumping is necessary to help maintain pressures in either the High or Low Zone. The Low Zone pumps pressurize the main 360 zone during high demand periods. The High Zone pumps pressurize the North Hill 400 zone. These pumps run continuously using a variable frequency drive to maintain the 400 foot hydraulic grade line in the High Zone. The fireflow pump is designed to pump into either zone should fire demands exceed the capacity of either zone. These pumps are further discussed in Chapter 3, System Facilities. INTERTIES The City has interties with many surrounding communities and water districts, most of which are for emergency use in the event of fires or water main breaks. At the extreme north end of the City Limits, there is an emergency intertie with the City of Seattle. The City also has interties with KCWD 125 at two locations in the Allentown and Foster neighborhoods. In the south end of Tukwila, interties are maintained with the City of Kent and the City of Renton. There is also an intertie with Highline Water District in the Segale Park area in the southern end of the City. These intertie locations are detailed in Table 1-2.

Horton Dennis & Associates, City of Tukwila Comprehensive Water System Plan, 1991 The existing water system facilities, service area characteristics, recommended improvements, and financing are discussed in this report. Recommended system improvements include constructing additional storage facilities, upgrading pipes in areas with deficient flows, and creating more looping within the system with additional water mains. The report was adopted by the City council in June 1993. Horton Dennis & Associates, Water District No. 25 Supplemental Engineering Study, June 1990 (Revised March 1991) Prepared as a supplement to the City of Tukwila Comprehensive Water System Plan presented prior to the City's annexation of the Allentown area, this report documents the existing water system of Water District 25, populations served, consumption, land use, system deficiencies, recommended improvements, and financing. Horton Dennis & Associates, SKYWAY Coordinated Water System Plan, November 1988 In order to establish coordinated policies and actions, this document was prepared in conjunction with the King County Planning Department and the participating water purveyors. This document identifies all participating water purveyors, establishes coordinated minimum design standards for improvements, establishes a plan for future service area boundary adjustments, and develops a plan to improve each system's reliability and 0 &M programs. City of Tukwila, Comprehensive Land Use Plan, December 1995 The City prepared this document as "a broad statement of community goals and policies that direct the orderly and coordinated physical development" of Tukwila. The Plan establishes the City's official position on planning and development, and "serves as a guideline for designating land uses and infrastructure development and for developing community services." Utility Services Associates, Water Line Leak Location Project, November 1996 Prepared after a leak detection survey was recommended in the City's 1991 WSCP, this report documents the findings from a surveying of over twenty-eight miles of the City's water mains for leaks. Pipes surveyed were found to be in good condition, and leaks were significant but manageable. 1-12 Gray & Osborne, Inc., Allentown Water and Sewer Improvement Project Design Report, January 1996 This report presents and analyses preliminary designs and cost estimates for water and sewer infrastructure improvements in the Allentown area of Tukwila. Project alternatives are discussed including methods of financing and project phasing, construction schedules, permit and easement requirements, and various design criteria. Engineer's recommendations are also given for project alternatives. State of Washington Office of Financial Management, 1997 Population Trends, October 1997 This annual OFM publication provides population trends and demographic data for the counties, cities, and towns of Washington. EXISTING SERVICE AREA The Tukwila City limits encompass an area of approximately 5,510 acres, including areas that were annexed by the City within the past ten years. All customers served by the City are within these limits. However, as discussed previously, there are many residents of Tukwila who are served by other water purveyors, namely KCWDs 20 and 125 and Highline Water District. Figure 1-5 presents the current City limits, existing water service areas, adjacent water purveyors, and interties with these purveyors. LAND USE AND ZONING The existing land use within the Tukwila Urban Center (TUC) provides for a wide variety of retail shopping, professional services, residential housing, public parks, and light industrial development. Predominantly residential areas of the City are located in the Allentown, Ryan Hill, Thorndyke, Foster, Riverton, North Hill, Cascade View, and Crystal Springs neighborhoods. These neighborhoods also include land uses such as churches, schools, parks, and neighborhood businesses. Most of the City's open space areas, including Fort Dent Park and the Foster Golf Course, are located in these residential zones. The Manufacturing/Industrial Center (M/IC) is located in the northern end of town along the Duwamish River and the Interstate 5 corridor. It includes the Boeing Field area and the business community along Pacific Highway S and E Marginal Way. Commercial/Light Industrial land uses are located adjacent to the Tukwila Urban Center and in the Segale Park and Andover Park areas, as well as along the Interstate 599 corridor south of Allentown. Existing City of Tukwila zoning laws are established by the Tukwila Municipal Zoning Code, adopted by the City Council under City Ordinance No. 1758 in 1995. Zoning codes and land uses are further defined and detailed in the City's Comprehensive Land Use Plan. These documents establish over 18 land use designations, their definitions, and the criteria that must be followed within each area. These items are summarized in Table 1-3. A copy of the City's Land Use and Zoning Map is presented in the Appendix. 1-13 TABLE 1-3 EXISTING MUNICIPAL ZONING DESIGNATIONS Zoning Designation .

FUTURE SERVICE AREA The City's Land Use and Zoning Map shows areas adjacent to the existing City limits that are potential annexation areas as established in the City's Comprehensive Land Use Plan. The Annexation Element of this plan identifies specific areas that could be incorporated into the City limits while fulfilling the criteria that are mandated in the Plan for annexed areas. The largest area for potential annexation is the Tukwila Valley South area. Currently this area has some residential development but is mostly rural and agricultural. The Highline Water District currently serves this area although the Tukwila system has the capacity to do so. The City's service area could also expand should it take over water service in the areas that are currently within the City limits but are served by other utilities. Specifically these areas would be in the Foster, Thorndyke, Cascade View, and Riverton neighborhoods that are currently served by KCWD 125 and KCWD 20. Although providing water service to these areas will technically be feasible in the future, the City's Planning Division has indicated that no immediate action is being considered by Tukwila. The City is also currently constructing new facilities to serve the Oxbow area in the north end of the City. Historically in the Seattle water service area, Oxbow is located near the intersection of S 102nd Street and West Marginal Place on the West side of the Duwamish River. Although not part of the City's existing service area, Oxbow is currently within the City limits and will be served from a new tap on Seattle's existing facilities. 1-16 GROWTH MANAGEMENT ACT CONSIDERATIONS Growth Management was passed into law in 1990 with the intention to stop uncoordinated and uncontrolled growth within the State of Washington which is considered to pose a threat to the environment. It was determined by the State that "it is in the public interest that citizens, communities, local governments, and the private sector cooperate and coordinate with one another in comprehensive land use planning". Several planning goals were adopted by the Growth Management Act (GMA)to guide the development and adoption of comprehensive plans. These goals include the following: 1) Encourage growth in urban areas. 2) Reduce inappropriate conversion of undeveloped land into sprawling, low- density development. 3) Encourage multi -modal transportation systems within urban corridors. 4) Encourage availability, various densities, and types of affordable housing to all economic classes within established urban areas. 5) Encourage economic development consistent with adopted comprehensive plans, promote economic opportunity, and revitalize growth in depleted sectors within the community. 6) Prevent private property from being taken for public use without just compensation. 7) Process permits in a timely and fair manner to ensure predictability. 8) Maintain and enhance natural resource-based industries. Encourage conservation of productive forest and agricultural lands. 9) Encourage open space and recreational opportunities, conserve fish and wildlife habitat, develop parks, and increase access to natural resource lands and water. 10) Protect the environment through best management practices. 11) Encourage citizen participation. 12) Ensure public facilities are adequate to support all developable areas without decreasing current service levels. 1-17 13) Identify and encourage the preservation of lands, sites, and structures that have archaeological or historical significance. The purpose of the Water System Comprehensive Plan is to coordinate Growth Management Act policies as established in the Comprehensive Plan with regard to future water demand. These policies include following Comprehensive Plan policies within the Water System Comprehensive Plan to establish such variables as the water service area and the service area population. These required Growth Management Act policies will greatly influence the determination of future water demand based on existing and proposed zoning and land use ordinances, as well as population projections. The City of Tukwila has already developed a Comprehensive Land Use Plan in response to the Growth Management Act and other King County planning goals. The City has also adopted their recently published Municipal Zoning Code as part of their effort to preserve and enhance Tukwila's long term growth. As a necessary component of a Water System Comprehensive Plan, additional service area policies have also been established by the City to standardize utility designs and connection policies. SERVICE AREA AGREEMENTS AND POLICIES ADJACENT PURVEYOR INTERTIE AGREEMENTS The City has service area agreements with KCWDs 20 and 125, Highline Water District, and the Cities of Kent and Renton. As mentioned previously, the City also has a Purveyor's agreement with the City of Seattle. Interties and service areas are shown in Figure 1-5. Service area agreements with neighboring cities and utilities are summarized below. Copies of the City's water system agreements are included in the Appendix. SKYWAY CWSP Signed and executed in the 1980s, this agreement defines the water service area boundaries for utilities participating in the SKYWAY agreement. These include areas served by the Cities of Seattle, Renton, Tukwila, and the Lakeridge and Bryn Mawr utility districts. It also makes provisions for transferring areas of service from one utility to another, reestablishing boundary lines, and resolving service area boundary disputes. An attachment to the agreement designates potential transfer areas among participating purveyors including the Tukwila takeover of Water District No. 125 customers in the eastern portion of the City. Since the completion of the City's previous water system plan, the City has fulfilled all of the obligations and commitments agreed upon in the SKYWAY Plan. This includes the takeover of the Creston Water Association and KCWD No. 25 within the City limits. The City's current service area boundaries, as shown in Figure 1-5, are therefore in accordance with the SKYWAY Plan. 1-18 A small number of customers in the Foster Point area are currently served by KCWD No. 125 and will be transferred to the City system when it is economically feasible for all parties. This area is shown in Figure 1-5 as being within the City's approved service area. Water District No. 125 The two emergency interties between Tukwila and KCWD 125 were requested by the District and signed into agreement in May of 1986. The agreement establishes costs for purchased water based on the "current wholesale new water" rate which Tukwila pays to Seattle plus five cents per hundred cubic feet (ccf). The agreement also establishes the hydraulic grade line at which water will be provided to the District as well as estimated available flows and annual consumption. Reciprocity is also established in the agreement so that Tukwila may also purchase water from the District if deemed necessary. The agreement was originally created to supply additional fireflows above what the District's system could maintain. Highline Water District Formerly KCWD No. 75, the District entered into an agreement with the City in 1979 in order to supplement fire flows in the Segale park area of south Tukwila. The intertie is designed to flow in both directions and is currently regarded as an emergency facility only. Costs for purchased water were established as $0.22/ccf and were amended to $0.25/ccf in the following year, although they appear to be based solely on rate schedules that were created in the early 1980s. City of Renton This agreement was originally created in 1978 and was renegotiated in 1995. Water rates are established as being the higher of the following methods; a) the current Seattle water rate for new summer water, or b) 0.738 multiplied by the current City of Renton retail commodity rate (in dollars per ccf). Each city is also required to own, operate, and maintain an appropriate metering device to measure water flow through the intertie. The agreement also establishes a maximum available water volume of 2.7 million gallons per day (MGD) and a maximum flow rate of 1,875 gallons per minute (gpm). Payment schedules and late penalties are also set forth in the agreement. The agreement may be terminated at any time by either party when ten days written notice is received by the other party. City of Kent Established in 1979, this agreement was created in order to "...provide emergency water flow and water supply to meet Kent's needs during periods of peak demand and for emergency flow and fire protection in both cities". The facility was constructed and financed by Kent and is therefore owned and operated by Kent as well. Water rates are established in the document as well as notification procedures for both parties when the intertie is used. Either party may terminate the agreement for material breach of its terms after giving twenty days written notice to the other party. 1-19 City of Seattle The Seattle/Tukwila Purveyor Contract was recently negotiated in 1982. It is a long term contract that is intended to continue through 2012 and it addresses many issues such as resale provisions, rate making, and demand charges. Water quality provisions require Seattle to deliver water that is in compliance with all applicable state and federal water quality laws and regulations. This provision is not binding during emergencies when reasonable efforts have been made to maintain adequate water quality. A minimum hydraulic grade line (HGL) of approximately 450 feet is established for Seattle at each Tukwila supply station except SS 11 which has a minimum HGL of 440 feet. _. Conservation requirements are also established in the water supply agreement. These state that Seattle will develop, adopt, and implement a conservation program with the approval and assistance of its purveyor customers. Tukwila in turn is required to develop and implement its own conservation program that is supportive of Seattle's program. SERVICE AREA POLICIES AND CONDITIONS OF SERVICE Service area policies and conditions of service are summarized in Table 1-4. Except where noted, these policies are included in the City's Municipal Code, Title 14, Water and Sewer. A copy of the Municipal Code is included in the Appendix.

This planning information will be used to evaluate the current state of the existing system and determine future needs based on foreseeable demographic trends for the next 20 years. Information to be used in the water system analysis for the City of Tukwila include historical growth and water demands for the system, including water purchase and demand; population projections as established by the Office of Financial Management (OFM), the Puget Sound Regional Council (PSRC), and the Tukwila Planning Department; and historical water use patterns for developing projections of future water demand. All stated information will be used in coordination with Growth Management Act policies. These projections will be utilized according to the needs of this Plan in order to properly assess the existing system's ability to meet future water demands. In addition, this Plan will recognize system deficiencies and determine the necessary improvements which will allow the system to meet or exceed the future water needs of an expanding population. CURRENT POPULATION, NUMBER OF SERVICES, AND WATER USE RESIDENTIAL POPULATION The population within the City Limits of Tukwila has increased significantly during the past decade, in large part due to annexations that took place in 1989 and 1990. According to the Office of Financial Management (OFM) 1997 data, the 1997 population of the City of Tukwila was 14,930 living in a total of 7,468 housing units. Of the 7,468 housing units, 3,079 (41 percent) were single-family residences (SFR), 4,031 (54 percent) were multi -family residences (MFR), and 358 (5 percent) were mobile homes. Housing has increased by almost 1500 units since 1990, and population has stabilized over the past five years since the boundary annexations. As discussed in Chapter 1, the City's water service area includes only a portion of the City's corporate limits. As a result, residential population within the water service area is significantly less than the population within the City Limits. Also, because the City has large portions of land within the service area zoned for commercial and industrial use, residential population is significantly more concentrated outside the service area. Table 2-1 shows City population and service area population increases from 1991 to 1997. 2-1 TABLE 2-1 SERVICE AREA AND CITY POPULATION INCREASES FROM 1991 TO 1997 � a � e tat: at,,a Year t �'. ... .:$..>i. s 5� � rT,� }t j, � t Ci ofTukwila r ri :a...•' �e ;t �' o ulation; , `s 'i•!! d .S:_.,.. wea."',7,_. a,' a.� ✓?

PSRC data and forecasting is further discussed in the population projections section later in this chapter. As shown in Table 2-1, the service area population for the City of Tukwila did not increase as quickly as the population within the City Limits. Although the City has incorporated large areas of land into its City limits, the water service to many of these areas has remained with the prior water purveyor in each respective area. TOTAL SERVICE CONNECTIONS The total number of water service connections within the City's service area in 1997 was 2,007. The single family and multi family residential water connections served by the City comprise over 55 percent of the total service connections; approximately 42 percent of the City's connections are for commercial and industrial connections.

WATER USE DATA COLLECTION Purchase and Demand History For water systems with their own source of supply, water supply measured at the source is usually referred to as "production" or "demand" water. Water supply measured at service meters is usually referred to as "consumption" water. However, because Tukwila is a purveyor without its own source of supply, the term production is not accurate. For the purposes of this report, the term "purchase" will be used to refer to wholesale water that is measured through Seattle's metering stations. The term "demand" will be used to refer to water consumption measured at service meters. Water demand is determined by summing the annual consumption at the individual service meters in the City's water service area. Service meter readings are collected by City personnel on a monthly basis. Purchased water is determined through monthly billing records from the City of Seattle. In addition, the City has installed telemetry at Supply Stations 11, 13, and 15 and is able to record hourly and total daily flow readings for each of these supply stations. Supply Station 10 will be equipped with telemetry in 1999. The water supply agreement between the City of Tukwila and the City of Seattle is briefly summarized in Chapter 1 and a copy of the contract is included in the Appendix. Historical water demand as a function of customer class is presented in Table 2-4. Table 2-4 also presents a history of both purchased water and lost and unaccounted for water as a percentage of purchased water. Figure 2-1 is a graphical representation of historical water demand as a function of each customer class. 2-3 TABLE 2-4 HISTORICAL WATER DEMAND AND PURCHASE BY CUSTOMER CLASS Year.

Commercial and industrial demand also increased at a proportionally similar rate between 1994 and 1995, then increased sharply in 1996. This increase was most likely a result of the City's takeover of water service to the Boeing Field area from Seattle Public Utilities at that time. Commercial and Industrial usage accounts for over 70 percent of total annual demand, as shown in Figure 2-1. 2-4 Lost and Unaccounted for Water Lost and unaccounted for water is defined as the difference between the amount of water purchased at the source meters and metered water demand. "Lost" water includes any water loss due to leaks or unauthorized uses such as illegal service connections. "Unaccounted for" water results from accounting errors, inaccurate meters, and water leaving the system for unmetered usage such as hydrant flushings and fire flows. The City's 1991 Comprehensive Water System Plan recommended a system -wide leak detection program as a means of identifying major leaks that were contributing to lost water. In 1996, the City contracted with Utility Services Associates to conduct a leak detection survey throughout the City's service area. Six major leaks were found during this survey, one of which accounted for 40 percent of the detected leak amount. The detected leaks, found in the Ryan Hill and Southcenter areas, accounted for a total of 18,720 gpd in lost water. All of these leaks were repaired by City staff in 1996. The City has also been replacing old and undersized pipes throughout the distribution system, reducing the potential for leaks and lost water. In 1996 new water mains were installed in the Ryan Hill area and in the Boeing Field area along E Marginal Way. As recently as 1997, new water mains were constructed in the Allentown neighborhood to replace inadequate pipes in that area. Lost and unaccounted for water for the City is calculated in Table 2-4 from supply volumes recorded at the supply stations and recorded demand numbers from customer meters. As indicated in Table 2-4, The City's lost and unaccounted for water has varied between 19 percent in 1994 to a high of almost 24 percent in 1996. Although the City has aggressively tried to reduce its lost and unaccounted for water, another leak detection survey will likely be required if lost and unaccounted for water is not reduced to fifteen percent or less of purchased water. Because the source of lost and unaccounted for water is uncertain, auditing of fire suppression lines for larger users should also be pursued. This method of reducing unaccounted for water is discussed further in Chapter 5 and 6. Peak Water Purchases Peak day purchase is the maximum amount of water used in a 24 hour period. Peak hour purchase is the largest amount of water used in a one hour period on a given day. Peak day and peak hour purchases usually occur in the summer due to the added demands of irrigation. Peak Day Purchase Peak day and peak hour purchases for the Tukwila water service area are tracked by Seattle as part of their billing system. Tukwila's purchases are categorized by which transmission main, or pipe segment, the supply stations are tapped from. As explained in Chapter One, Supply Stations 13, 14, 15, and 16 are tapped on CRPL 4 and Supply Station 169 is tapped on CRPL 3. Supply Stations 10 and 11 are tapped on the West 2-5 Seattle Pipeline (WSPL). These are the stations that contribute to Tukwila's peak demands. These peak demands by purveyors can strain Seattle's supply system during peak demand times by lowering available head in the transmission lines. In order to discourage excessive withdrawal rates during peak times and encourage construction of storage facilities, Tukwila and other purveyors are penalized by Seattle for excessive peak purchases. This is part of Seattle's demand metering program. Demand metering and peak penalties are explained in detail in Chapter Three. The highest peak day purchases for each transmission line segment for 1997 are shown in Table 2-5. The peak day purchases for each line segment did not occur on the same days in 1997. The ratio of peak day to average day purchase of 1.83 is comparable to the DOH Waterworks Standards Guidelines suggested peaking factor value of 2.0. Tukwila's calculated peaking factor of 1.83 will therefore be used in this report to project future peak day purchases on Tukwila's water system.

Table 2-7 shows the average peaking factor for peak day to peak hour as 1.16. This number is significantly lower than the peaking factor of 1.74 which is recommended by DOH in their Waterworks Standards manual. Peaking factors in Tukwila are dampened significantly by commercial and industrial customers whose demands are usually more consistent throughout the day compared to residential water demands. Since it is more representative of actual conditions within the Tukwila water system, this report will use the calculated peaking factor for projecting future demand conditions. Large Water Users The largest water users in the City of Tukwila's water service area in 1997 are shown in Table 2-8 below. These customers accounted for approximately 35 percent of metered demand in 1997 and over 40 percent of Commercial/Industrial water use in 1997. Equivalent Residential Units Use of Equivalent Residential Units (ERUs) is a way to express water use by non- residential customers as an equivalent number of residential customers. ERUs are calculated by dividing the total volume of water utilized by the single family customer class by the total number of residential connections. This number defines the average residential water use. For the City of Tukwila, the 1997 average residential water use was 176 gpd per ERU. The volume of water used by other customer classes can then be converted to ERUs by dividing by the average residential water use. Table 2-9 provides the number of water service connections by customer class, the average daily demand for each class, the ERUs for each class and the average ERUs per connection. As shown in Table 2-9, each connection serving a multi -family unit uses nine times as much water as a single family connection. Each Commercial/Industrial connection uses an average of ten times the amount of water used by a Single -Family connection. 2-7 TABLE 2-8 1997 LARGE WATER USER DEMAND Customer .

Per Capita Demand As mentioned previously, commercial and industrial demands account for over 70 percent of the City of Tukwila's total water demand. Per capita demand is based on the total water purchased divided by total residential population. Per capita demand numbers are then used along with projected population increases to estimate total future demands. However, because Tukwila's service area population is small compared to commercial and industrial users, projected population increases cannot adequately account for anticipated future increases in water demand. Therefore, in this report, per capita demands will represent only single family and multi family residential water demands. This data will then be used to project future residential water use only. Present commercial and industrial water demands will be separated from residential demands, and future commercial and industrial water demands will be projected separately. Historical lost and unaccounted for water percentages will then be added to all future demands to calculate the projected total water purchases. 2-8 d Historical consumption numbers are available through the City's billing department. Service area populations have been estimated based on current OFM data and PSRC data discussed previously in this chapter. The estimated per capita demand for the City over the last four years is shown in Table 2-10. These numbers will be used for projected residential water demands in the next section of this report. PROJECTED POPULATION AND WATER DEMAND Population for the City of Tukwila is projected using population and housing data provided by OFM, and FAZ/TAZ data provided by the PSRC. The following section explains how population projections were made. The projected population, in conjunction with per capita water use, is then used to determine future water projections.

PROJECTED RESIDENTIAL POPULATION Transportation Analysis Zone (TAZ) and Forecasting Analysis Zone (FAZ) Models The transportation analysis zone (TAZ) model is a computer based simulation used to assist in the forecasting of travel flows and the planning of future transportation needs. TAZ uses the census tract data and numbering system to identify areas with growth potential, either undeveloped or underdeveloped, within each residential zone of a city and to determine growth trends, housing changes, and population densities. The forecasting analysis zone (FAZ) model is used to project housing, employment, and population data into the future for designated zones throughout the Puget Sound area. Each FAZ is comprised of one or more TAZ areas, and data from both models is used in this report. A map of the applicable TAZ and FAZ is included in the Appendix. The City's water service area covers several zones in the TAZ model, and the City limits encompass pieces of over ten different zones. Two zones from the FAZ model encompass most of the City Limits as well. Because these zones boundaries were not based exactly on the City's corporate limits and water service area boundaries, estimates regarding population projections and service area populations were made. As discussed 2-9 previously, Commercial/Industrial water use accounts for over 70 percent of demand on an annual basis. Although residential population in the City Limits and in the City's water service area has risen at a rate of less than 1 percent annually, water demand has risen at a far faster rate during the same time period. As shown previously, water demand increased by almost 30 percent between 1995 and 1996, mostly due to an increased commercial and industrial customer base. Therefore, making accurate projections of future water demands cannot be based solely on the projected growth of the residential sector. This report will utilize data both from FAZ and TAZ models and from OFM population projections to estimate future water demand. TAZ and FAZ numbers specific to the Tukwila area will be used to project residential population growth within the City's service area, and OFM population projections for incorporated King County will be used to estimate the growth of the Commercial/Industrial customer class and their future water use. Compared with localized TAZ growth projections, population projections for the county as a whole better represent future commercial and industrial growth in the Tukwila service area. Determination of Rate of Population Increase The map in the Appendix shows that the TAZ areas encompassing the City's water service area are 263 (Boeing Field, Allentown, Ryan Hill), and 262 (Foster, Foster Point, Southcenter). TAZ data for 1997 indicates that these two areas had a residential population of 1,204 and 4,422 respectively for a total of 5,626 people in 1997. FAZ population projections are included in the Appendix. Both FAZ areas were found to have approximately the same projected growth rate of approximately 40 percent over the next two ten year periods. Population Projections Projected populations were calculated by using the FAZ growth rate and applying it to the current TAZ population in that FAZ area. This percentage increase is applied linearly so that the total population increase in both TAZ areas over ten years adds up to the percentage increase for the entire FAZ area. Table 2-11 shows the projected residential population in the City's existing service area. PROJECTED COMMERCIAL AND INDUSTRIAL GROWTH The total number of Commercial/Industrial connections served by the City of Tukwila is 835. These non-residential water needs have accounted for over 70 percent of the City's metered demand. As shown in Table 2-8, the City's nine largest water users accounted for almost 35 percent of the total metered demand in 1997. Based on the City's past service history and projected land use, non-residential water users will continue to be the predominant consumers in future planning horizons. Most of the commercial activity within Tukwila is influenced by surrounding cities and counties. As a result, commercial and industrial (C/I) use will be estimated by applying OFM's projected growth rate for King County to the current CII water use. 2-10 TABLE 2-11 PROJECTED WATER SERVICE4AREA POPULATION THROUGH 2017 ',. ....

City personnel and planning staff anticipate commercial and industrial growth within the City of Tukwila will increase at a similar rate. Therefore the rate of growth for commercial and industrial water demand will be projected at 1.0% annually. As with residential population projections, this twenty percent increase will be applied linearly between 1997 and 2017 so that the projected demand increase per year will be at a constant rate. As shown in Table 2-8, Boeing is by far the largest water consumer in the City's water service area. City planners and public works staff anticipate that Boeing industries will expand at the same rate as other commercial and industrial users in the King County area. Therefore, Boeing's water demand growth is projected to be one percent annually from 1997 data. WATER DEMAND FORECASTING Residential Water Use Projections Residential population estimates and projections for the Tukwila water service area were established earlier in this chapter. PSRC population forecasting data was used to estimate residential population growth within the City's service area through the twenty year planning horizon. Per capita demand numbers were calculated for 1997 in Table 2-10 and are used as a basis for projecting future residential demands in Table 2-12. Table 2-12 presents projected residential demands based on constant future per capita demands. If successful, conservation efforts discussed in Chapter 5 could reduce water system demands by 0.5% annually. This projected demand scenario is also presented in Table 2-12. However, for planning purposes, this report will assume future per capita residential demands as constant for determining system capabilities, deficiencies, and recommended improvement. As shown in Table 2-12, residential population and average day demand are anticipated to almost double in the twenty year planning horizon using TAZ data and constant per capita demands. 2-11 TABLE 2-12 PROJECTED RESIDENTIAL AVERAGE DAY PURCHASES THROUGH 2017 e it ii jYear ,, t° ri t� 4 o ected Residential ?Population, .: • rig �' 4' Per{Capita Demand:(gl?d)' Residential Aver`ageDay Demand .' , (gpd), ,� m ..41 'iR,,,i'o. % . vsf� 'Constain'i Per CapitavDemand ,:i.' gpcd), : r> 94 wnd- 0:5° i niial' ConservationrCap Savingsa(gpcd) YM ,, p%,,C,onstant.

Commercial and industrial water use is based on 1997 demand numbers shown in Table 2-9. Total projected commercial and industrial average day demands through the twenty year planning horizon are shown in Table 2-13. As with Table 2-12, Table 2-13 also presents proposed commercial and industrial average day demands assuming only a 0.5% annual increase in consumption due to successful conservation efforts. As mentioned previously, this report will use the more conservative demand projections for determining future water system needs. Conservation efforts are discussed in detail in Chaper 5. As demonstrated previously, Commercial/Industrial demands are based on customer classes as defined by the City. 2-12 TABLE 2-13 PROJECTED COMMERCIAL AND INDUSTRIAL AVERAGE DAY DEMAND THROUGH 2017 9� -A ` ' � '" .. uYear k"8'+ i% 1 Pro ected� '' ABoeing ,� . , 'Demand�with 6 {6 +T , [ a' ^�. r, r1% Annual+ _ 1 GyL �'�'� G owth (gp,,d)! t 3Ml Jj d;3$fw¢ f V ,pro ected a - OthierrC/I }° 7"^ Demandrwith�.:` % Annual`` l. /oa �� � �° �J S .,Growth (gpd) $ b iia'.. h .,p"' !

As previously, projected purchase data includes lost and unaccounted for water as calculated for 1997 in Table 2-4. Peak day purchase projections are calculated from average day purchases using a peaking factor of 1.83 as shown in Table 2-5. Peak hour purchase projections are calculated from peak day purchases using a peaking factor of 1.16 as shown in Table 2-7. It is recognized that a lost water rate of 21.2% is high. However, it remains to be determined if these losses are the result of leaks and theft or are unaccounted for due to inaccurate meters. Repairing leaks will reduce lost water while calibrating inaccurate meters will not change actual water demands since this water will continue to be consumed. Because the source of the lost water is not well defined, 21.2% will be used for the water demand forecast as a conservative estimate. The projected purchases for 2003 and 2017 are used in the hydraulic model to determine system conditions under these demands and to determine if there are any system deficiencies. The hydraulic model is discussed in detail in Chapter 4. TABLE 2-15 PROJECTED PEAK DAY AND PEAK HOUR PURCHASES THROUGH 2017 =,.,, .Y t ..q_. ac R ' r je ted twy.,�6�y ryT9 , �6Y j� .

The City could also see an increase in water demand in the future due to expansion of the City's water service area. Although the City does not anticipate rapidly expanding its service area in the next few years, it is important to note these areas for future reference. • Currently the City is annexing services in the Oxbow region of the City, currently served by Seattle. This area is located in the northern industrial area of the City west of the Duwamish River and east of Highway 99. The City has recently designed a new supply station off the West Seattle Pipeline (WSPL), and the project will include new eight -inch distribution mains, and replacement of existing services in that area. 2-14 Construction is anticipated to begin in September 1998, and services should be transferred from Seattle to Tukwila by the end of 1998. • The City also anticipates service area growth on the south side of the Duwamish River at the Pacific Highway bridge crossing. Currently the City's 12 -inch water main in Pacific Highway dead ends before it crosses the bridge. The City anticipates commercial and industrial growth in this area in the next few years and is considering using developer financing as part of the funding needed to improve this area. However, developer activity cannot be predicted sufficiently to project future water needs. Therefore projected growth in this area will not be a part of this plan. The area is within the City limits and is currently served by KCWD 125 using two and four -inch water mains. • The largest potential service area boundary change is in the eastern portion of the City in the Riverton and Thorndyke neighborhoods. This area is also within the City's corporate limits and is currently being served by KCWD 125. The City currently believes that customers in this region are receiving excellent service from their current provider. However, these customers are within the City limits and it is the City's goal to ultimately serve all customers within their City limits. This boundary adjustment will require negotiation with KCWD 125 and will likely be coordinated through the SKYWAY Water Utility Coordinating Committee. The City does not anticipate that this boundary change will occur within the six year planning horizon, and therefore the effects of such a decision are not discussed in this plan. However, as with the previous example, customers in this region are mainly serviced by two and four -inch distribution mains. Because these existing water lines do not meet minimum City construction standards, the City will have to make significant improvements to the existing system if a takeover of this area is negotiated. WATER RATES CITY OF SEATTLE WHOLESALE BILLING RATES Tukwila is billed by Seattle on a monthly basis for water purchased through each of its supply stations. Several different charges apply, and these charges are summarized in Table 2-16. CITY OF TUKWILA RATES Consumption Charges Current water rates for the City of Tukwila were passed into law by the City of Tukwila on May 19, 1997 as Ordinance No. 1798. Table 2-17 shows the minimum monthly charge, which is based on meter size, and Table 2-18 shows demand charges per 100 cubic feet. The City also has seasonal volume charges which are consistent with the seasonal wholesale purchase rates. 2-15 TABLE 2-16 WHOLESALE PURCHASE RATES (Effective January 1, 1998) Whole"sge Water Bill -� s dd M1'l4 k •� r►� p sd�q;_�� �yy,,��,.{q3b��/ Componen ( ``(Yt:i?ANdiCY iY Chits 4 � `' ' �, ,,g gg�ry}�%}}t��-- L .Y: V !o u •�iy w?.` .. ih: .' dal Comments " v.+YS:, �a %1". ,��. t�,,+��cc�,wa� 3 r� - .,ae �r tt �r,�,, Y�<.Fh'a1Xw9 �` ' BY,, . c ^ ' ' .r :, m Old Water: Off Peak $0.31 per ccf September 16 - May 15 Old Water: Peak $0.80 May 16 - September 15 Growth Surcharge $1.05/ccf surcharge Year-round surcharge.

These revised fees are intended to refinance the costs incurred by the City for improving the water distribution systems in these neighborhoods during the past two years. The charges increase by a fixed amount annually and are designed to encourage developers and new customers to connect to the new system as soon as possible. This rate structure is intended to accelerate neighborhood revitalization and the recovery of construction costs. Table 2-20 presents the new connection charges for these areas.

Design standards are developed which identify criteria that is applicable to the City of Tukwila water system. A water quality and facility analysis then compares these design standards to the existing system facilities and water quality. Based on this comparison, water system deficiencies can be identified and recommendations to improve compliance with the required standards can be developed. Because the City of Tukwila purchases water from the City of Seattle through Seattle Public Utilities (SPU), many of the water quality monitoring requirements do not apply. Other system parameters such as operator certifications and the City's cross connection control program are discussed in the City's Operations and Maintenance Manual (O&M), included in the Appendices of this document. SYSTEM DESIGN STANDARDS Performance and design criteria typically address the sizing and reliability requirements for source, storage, distribution, fire flow and water quality. Construction standards set forth the actual materials and construction methods that contractors, developers, and the City must follow when constructing water system facility improvements. Construction standards, including developer extension guidelines, have been developed for the City and are provided in a separate document. In this chapter, the design standards are divided between general facility standards and water quality standards and are discussed in the following order: • General Facility Standards 1. Average and Peak Day Purchase 2. Peak Hour Purchase 3. Storage Requirements 4. Minimum System Pressure 5. Minimum Pipe Sizes 6. Backup Power Requirements 7. Valve and Hydrant Spacing • Water Quality Standards 1. Applicable Drinking Water Regulations 2. Existing Drinking Water Quality Standards 3. Anticipated Future Drinking Water Quality Standards 4. Water Quality Monitoring Schedule 3-1 GENERAL FACILITY STANDARDS The Washington State Department of Health (DOH) relies on various publications, agencies and the utility itself to develop and establish design criteria. WAC 246-290- 200, Design Standards, lists the various criteria allowed by the DOH. The following gives a brief description of the two most widely recognized performance and design standards. Table 3-1 provides a summary of the recommended water system design standards. Table 3-2 provides a comparison between the DOH Waterworks Standards and the City of Tukwila standards with regard to general facility requirements. • Group A Public Water Systems Waterworks Standards, Washington State Department of Health (DOH), (April 1996) Significant revisions to the State Waterworks Standards have recently been completed by the DOH. Though still in draft form, any subsequent changes are expected to be minor. These standards will serve as a guideline for the preparation of plans and specifications for Group A public water systems in compliance with WAC 246-290. If this document specifies standards different from the Ten States Standards, the provisions of the DOH Standards will govern. • Recommended Standards for Water Works, A Committee Report of the Great Lakes - Upper Mississippi River Board of State Public Health and Environmental Managers (1992) Commonly known as the Ten States Standards, this document formalizes the design standards recommended by a water supply committee representing ten midwestern and upper Great Lake States and the Province of Ontario. The report of the Water Supply Committee was first published in 1953, and subsequently revised and published in 1962, 1968, 1976, 1982, and 1992. The report presents recommendations for both design and construction standards; however, the construction standards are somewhat general in nature with minor emphasis on materials specifications. Since surface water treatment is quite common in the Midwest and Upper Great Lakes, the Committee report tends to concentrate on water treatment plant design and operation. Because Tukwila is part of a Consecutive Water System, some of these design standards are modified or waived in the DOH Waterworks Standards manual. This is detailed further in the discussion of Tukwila's storage facilities and requirements. 3-2 TABLE 3-1 RECOMMENDED WATER SYSTEM DESIGN STANDARDS gtillard ed4,',, •Si7,.

' 3-3 TABLE 3-2 GENERAL FACILITY REQUIREMENTS Standard DOH Waterworks Standards (Draft April 1996) City of TukwiliStandard Average Day and Peak Day Purchase Average day purchase should be determined from previous actual water use data. Peak day purchase is estimated at approximately 2.0 times the average day purchase. Average day purchase is determined from the previous year's data. Peak day purchase was determined using a peaking factor of 1.83, which was derived from actual data. Peak Hour Purchase Peak hour purchase is determined using the following equation: PHP = 1.4 (PDP)(NRR„)/1440 PHP = Peak Hour Purchase PDP =.Peak Day Purchase NERU = Equivalent Residential Units Peak hour purchase is determined by applying a peaking factor of 1.16.. Historical data indicates a peaking factor at the supply stations of 1.16, which is indicative of the actual system conditions for the City of Tukwila's water service area. Storage The sum of: • Equalizing Storage VES = (QPH - Qs)* 150 • Standby Storage VSB = 2*(ADP) • Fire Suppression Storage (if required) VHS = NFF*T QP„ = Peak hour purchase Qs = Sum of all source capacities except emergency sources NFF = Needed Fire Flow T = Time (Minutes) The City of Tukwila relies upon the reliability of Seattle's regional water supply system to meet DOH storage requirements (per DOH Waterworks Standards Section 9.2.7). Minimum System Pressure The system should be designed to maintain a minimum of 30 psi in the distribution system under peak hour purchase and 20 psi under fire flow conditions. The system should maintain a minimum of 20 psi at ground level at all points in the distribution system under all conditions of flow. Minimum Pipe Sizes The minimum size for a transmission line shall be determined by hydraulic analysis. The minimum size distribution system line shall not be less than 8 -inches in diameter. The minimum distribution system line size shall not be less than 8 -inches. Minimum multi family, commercial, and industrial water mains shall be 10" if looped and 12" if non -looped. Backup Power On-site back-up power equipment or gravity standby storage shall be provided unless the power grid meets the minimum reliability criteria. Standby storage is provided by Tukwila and Seattle storage facilities. Valve and Hydrant Spacing Sufficient valving should be placed to keep a minimum of customers out of service when water is turned off for maintenance or repair. Fire hydrants on laterals should be provided with their own auxiliary gate valve. Valve and hydrant standards are outlined in the City of Tukwila Public Works Water Construction and Development Standards. 3-4 WATER QUALITY STANDARDS Applicable Drinking Water Quality Regulations Table 3-3 lists the existing and future drinking water regulations and the status of each regulation. Existing state law contains regulations of bacteriological contaminants, inorganic chemicals and inorganic physical parameters (IOCs), volatile organic chemicals (VOCs), synthetic organic chemicals (SOCs), radionuclides and trihalomethanes (THMs). Six additional drinking water regulations will become effective in the next ten years, and these new regulations will define new regulatory requirements for sulfate, radionuclides, additional IOCs and SOCs, arsenic, additional disinfection by-products and bacteriological contaminants. Many of the regulations shown in Table 3-3 define treated source water quality standards and establish source water quality monitoring schedules. Many of the federal and state water quality monitoring requirements do not apply to the City of Tukwila since it purchases treated water from the City of Seattle. However, the City should be familiar with the requirements described in this section since they affect both the quality and cost of water purchased from the City of Seattle. The City of Tukwila is required to conduct distribution system monitoring for bacteriological contaminants, disinfection by-products, residual disinfectant, and lead and copper. Existing Drinking Water Quality Standards The 1974 Safe Drinking Water Act (SDWA) and its 1986 and 1996 amendments established specific legislation for regulation of public water systems by federal and state governments. The federal government, specifically the US Environmental Protection Agency (EPA), is authorized to develop national drinking water regulations and oversee the implementation of the SDWA. Once federal regulations become effective or promulgated, states with primary enforcement responsibility must adopt the federal law as state law and accept the primary responsibility for implementation and enforcement of the law. The State of Washington has adopted as state law all of the SDWA regulations promulgated by the EPA as of July 1, 1993. The State has delegated the authority to oversee drinking water regulations to the State Department of Health. State drinking water regulations are published in WAC 246-290 and establish monitoring requirements, maximum contaminant levels, and requirements for follow-up actions. Minimum standards for water quality are often specified in terms of Maximum Contaminant Levels (MCLs). Primary MCLs are based on chronic and/or acute human health effects. Secondary MCLs are based on factors other than health effects, such as the aesthetic quality of the water. Public water purveyors have the responsibility of meeting the requirements of the regulations on a day-to-day basis. Monitoring requirements are often established for regulated contaminants to ensure that water systems demonstrate compliance with MCLs or treatment technique requirements. Public 3-5 water suppliers are also required to retain certain records and submit reports to the State DOH.

[2] Although the ICR is not in the WAC, it remains a federal rule under the EPA. 3-6 On August 6, 1996, additional amendments to the SDWA were signed into law as Public Law 104-182. The 1996 amendments updated the development of regulations concerning arsenic, radon, groundwater disinfection, and filtration and also authorized more than $12 billion in federal funds for various drinking water programs through the year 2003. Bacteriological Many serious diseases are caused by bacteria, a class of single celled organisms. Indicator organisms are often used in monitoring of bacterial contamination of drinking water. Typical indicator organisms are total coliform, fecal coliform, and E. Coli. Violations of bacteriological MCLs are as follows (WAC 246-290): • During routine sampling, coliform is detected in more than one sample in a single month (for systems taking less than 40 samples per month) • Fecal coliform present in a repeat sample, which is a sample collected to confirm the presence of total coliform detected in the routine sample. • E. Coli present in a repeat sample • Coliform present in a set of repeat samples collected as a follow-up to a sample with fecal coliform or E. Coli present Each water purveyor is required to prepare a coliform monitoring plan and have it available for inspection upon request. Disinfection By -Products Trihalomethanes (THMs) are a group of organic compounds that can be formed as a result of drinking water disinfection by chlorine and are therefore often referred to as disinfection by-products. THM standards are applicable to the City of Tukwila. WAC 246-290-300 specifies that purveyors of public water systems which serve a population of 10,000 or more and provide water treated with chlorine or other halogenated disinfectants must monitor the system for disinfection by-products. The City of Tukwila is required to collect one water sample from the extreme end of the distribution system every three months. The sample must be analyzed for total trihalomethanes (TTHMs). TTHMs include the sum of the concentrations of four disinfection by-products: trichloromethane, bromodichloromethane, dibromochloromethane, and tribromomethane. The current MCL for TTHM is 0.10 mg/L (100 p.g/L) and is based on the running annual average of four quarterly samples. Residual Disinfectant Water entering the distribution system must contain a residual disinfectant concentration of free chlorine of at least 0.2 mg/L. Distribution system residual disinfectant concentrations measured as free chlorine must be detectable in at least 95 percent of the samples taken each calendar month. Residual disinfectant concentration within the 3-7 distribution system is measured at the same time and location that routine coliform samples are collected. Asbestos Since the City of Tukwila's distribution system does not contain asbestos/cement water lines, it is not required to monitor for asbestos. For purveyors with asbestos pipe in the distribution system, one sample in an area with AC pipe is required every nine years in accordance with 40 CFR 141,23 (b). The MCL for asbestos is 7 million fibers/liter larger than 10 microns. Lead and Copper The EPA published the final regulations for the Lead and Copper Rule (LCR) in 1991 as part of the 1986 Safe Drinking Water Act Amendments. LCR is intended to reduce tap water concentrations of lead and copper. LCR requires an initial monitoring phase in which two rounds of water sampling for lead and copper are conducted. Lead samples collected according to the LCR must have concentrations below the `Action Level' of 0.015 mg/L at the 90th percentile. Similarly, copper samples must have concentrations less than 1.3 mg/L at the 90th percentile. Systems exceeding the action levels are required to provide public notification and implement a program for reducing lead and copper levels. The City of Tukwila is required to monitor for lead and copper presence in their system in accordance with this rule. IOCs, VOCs and SOCs The State of Washington has adopted Federal MCLs and monitoring regulations for inorganic chemicals and physical parameters (IOCs), volatile organic compounds (VOCs), and synthetic organic compounds (SOCs). The Federal standards were originally promulgated in the Phase I Rule and updated in the Phase II and Phase V rules. The monitoring for these regulations is conducted by the City of Seattle. Information Collection Rule The Information Collection Rule (ICR) was implemented for large water systems (>100,000) in 1996. It will generate large volumes of data on the occurrence of microbiological agents, disinfection by-products, and treatment for a variety of surface and ground water sources across the country. Water purveyors are required to submit monitoring results directly to the EPA for compiling and analysis. The ICR establishes a series of monitoring requirements for surface and ground water systems. These monitoring requirements focus primarily on microbiological contaminants and disinfection by-products. The information will provide the EPA with accurate data on levels of microbiological contaminants and disinfection by-products in different types of source waters throughout the country. The EPA will use the information to set regulations that are appropriately based on the quality of water and level of treatment needed. This data will directly affect the development and 3-8 implementation of the Long Term 2 Enhanced Surface Water Treatment Rule which is expected to be promulgated by the federal government in 2002. Another major component of the ICR is bench/pilot scale testing requirements to control disinfection by-product precursors. This data will be used to make revisions to the Long Term 2 Enhanced Surface Water Treatment Rule. Surface water systems that serve more than 100,000 people and most groundwater systems that serve more than 50,000 people and use a chemical disinfectant will be required to conduct studies unless certain criteria are met. This information will be used to designate appropriate treatment technologies for the Stage 2 D/DBP Rule. The ICR will not directly affect the City of Tukwila because of their status as a purveyor with the City of Seattle. Surface Water Treatment The Surface Water Treatment Rule (SWTR) was incorporated into the WAC in April 1993 and updated in July 1994. This Rule established water quality requirements for surface water sources and groundwater sources that are under the direct influence of surface water (i.e., GWI sources). The SWTR has indirect impacts on the quality and cost of water purchased by the City of Tukwila, but does not require monitoring or other actions by the City. The purpose of the SWTR is to protect against acute health risks from waterborne microbiological contaminants. Requirements for adequate disinfection and contact time are established. Filtration may be required if water quality standards and source requirements do not meet specified criteria. Treatment technique requirements are established instead of MCLS for Giardia lamblia, viruses, heterotrophic plate count bacteria, Legionella and turbidity. Disinfection with or without filtration must achieve at least 99.9% removal and/or inactivation of Giardia lamblia cysts and 99.99% removal and/or inactivation of viruses. Anticipated Future Drinking Water Regulations Anticipated future drinking water regulations are listed in Table 3-3 along with existing water quality regulations. The Department of Health has indicated that many of these regulations will not be promulgated by the federal government until after 2001. At that point, individual state governments are usually given a grace period of several months to two years before it must be adopted as state law. This allows time for a public comment period and publishing of the regulations in the state administrative code. Radionuclide Rule By the year 2000, the EPA is expected to publish the final version of the Radionuclide Rule, which will revise radionuclide MCLs. The new MCLs will incorporate existing state MCLs and the limits in the proposed version of the radionuclide rule. Although a radon MCL was included in the proposed Radionuclide Rule, the final version of this rule 3-9 will exclude radon. A radon MCL will be issued separately. This rule is anticipated to take effect in 2003. Arsenic Rule The 1996 amendments to the Safe Drinking Water Act provided additional time for research to resolve the scientific uncertainties surrounding the regulation of arsenic. A final MCL for arsenic is scheduled to be published by January 2001, and systems will be required to be in compliance with the MCL three to five years later. Ground Water Rule The Ground Water Rule (GWR) is one of the 1996 Amendments to the Safe Drinking Water Act. The rule is expected to be published in 2001 and is not expected to take effect until after the year 2004. This rule would establish a method for determining if disinfection of a groundwater source is required, and it would establish disinfection standards for those sources where disinfection is required. In the draft proposed rule, disinfection standards are established in terms of a residual disinfectant concentration and a disinfection contact time requirement. These standards will depend in part on characteristics of the water, including pH and temperature. In general, disinfection is more effective at lower pH and higher temperatures. However, the draft rule does not quantify specific process requirements. Long Term 2 Enhanced Surface Water Treatment Rule The Long Term 2 Enhanced Surface Water Treatment Rule (ESWTR) will revise surface water microbiological standards. The Long Term 2 ESWTR is expected to be finalized in 2002, and the contents of the Long Term 2 ESWTR will be based on ICR data. As presently proposed, the ESWTR would be applicable to surface water systems serving more than 10,000 people. Although this rule will not apply to Tukwila, the City of Seattle will be directly affected by the ESWTR. Disinfectants/Disinfection By -Products Rule The Disinfectants/Disinfection By-products (D/DBP) Rule will establish residual disinfectant concentrations and maximum contaminant levels for disinfection by- products. The rule will be implemented in two stages, and the final rule of Stage 1 was published in the Federal Register on December 16, 1998. Stages 1 and 2 of the D/DBP Rule are applicable to the City of Tukwila. Table 3-4 summarizes the final D/DBP Rule standards. SYSTEM ANALYSIS This section provides an analysis of the water quality testing performed by the City of Tukwila and the City of Seattle. The City of Tukwila is required to perform chlorine residual bacteriological, THM, and lead & copper testing. The City of Seattle performs all other water quality monitoring. This section also includes an analysis of each system 3-10 facility's capacity to meet existing and future demands. The ability of the system to meet the water quality and facility design standards, as discussed in the previous section, is examined. These include an analysis of existing water quality and water system facilities. The system's deficiencies will be determined at the conclusion of this analysis. WATER QUALITY ANALYSIS Results of Water Quality Monitoring by the City of Tukwila The results of the water quality monitoring completed by the City of Tukwila are discussed in the following sections. The actual data collected for each of the specific parameters is provided in the Appendix. TABLE 3-4 PROPOSED D/DBP RULE STANDARDS • Parameter p ...

A copy of the coliform monitoring plan is included in the Appendix. As shown in the City's coliform monitoring plan, the City is currently required to take nine or eleven samples per month, depending on the time of year. This is a reduced rate of sampling as directed by DOH in a letter to the City on April 15, 1997. The City's Coliform Monitoring Plan was also reviewed and approved by DOH in this same letter. City of Seattle water quality data indicates that Tukwila had no coliform detections in 1996 and 1997. Chlorine residuals at Tukwila's sample stations have been between 0.4 and 1.5 mg/L and have averaged about 0.9 mg/L during this same time period. Lead and Copper The City of Tukwila performs lead and copper testing in conjunction with Seattle Public Utilities. Sampling and testing for 1997 was performed in March and April of that year and test results indicate that the samples did not exceed the action levels set by the USEPA. Two samples were submitted for testing, one taken in the Allentown area and one taken in the North Hill area. Lead concentrations for each sample were 4.8 µg/L and undetected respectively, and copper concentrations were 0.05 mg/L for both samples. 3-11 Trihalomethanes The City of Seattle is also hired by Tukwila to perform quarterly and yearly sampling and testing for THMs. THM samples are taken at the same stations as coliform samples. Data available from Seattle indicates that the City of Tukwila has never exceeded the TTHM MCL of 100 µg/L. Test results from 1996 and 1997 are presented in the Appendix. Consumer Confidence Report (CCR) When the U.S. Congress passed the 1996 Safe Drinking Water Act (SDWA) amendments, the U.S. EPA was given a mandate to require community water systems to provide their customers with a Consumer Confidence Report (CCR). A CCR is intended to inform customers about drinking water quality in their respective systems and must describe any risks associated with contaminants in drinking water. Final regulations require water purveyors to delivery their first CCR by October 1, 1999 for the calendar year 1998. Thereafter, annual reports are required annually by July 1st in order to cover the preceding calendar year. Tukwila is required to prepare a CCR, and AWWA recommends that utilities plan to have their first CCR completed by July in order to allow for an adequate safety margin for compliance. Results of Water Quality Monitoring by the City Of Seattle Since the City of Seattle is the sole water supplier of the City of Tukwila, the quality of Seattle's water is very important to Tukwila. A detailed review of the water quality of the City of Seattle public drinking water system is provided in the City of Seattle 1994 Water System Plan. Seattle also compiles a water quality analysis for the Tolt and Cedar River systems on a quarterly basis, samples of which are included in the Appendix. The City of Seattle analyzes samples collected from the source surface water for bacteriological contaminants, IOCs, SOCs, and VOCs, total organic carbon, radionuclides, turbidities, Giardia and Cryptosporidium, algae, chlorophyll, and many more parameters. Distribution system parameters analyzed include bacteriological contaminants, TTHM, haloacetic acids, choropicrin, haloactetylnitriles, chlorine residuals, pH, alkalinity, turbidity, pesticides/herbicides, metals (aluminum, iron, manganese, antimony, lead, copper, arsenic), fluoride, and primary inorganics. The pH of treated Cedar River water averages 8.2 and the alkalinity averages 19 mg/L as CaCO3. Raw water pH and alkalinity average about 7.3 and 8 mg/L respectively. The treated water has low color and turbidities are consistently less than 0.5 NTU. A review of 1996-1997 data indicates that no inorganic, organic, radionuclide, or THM MCLs have been exceeded. Treated Cedar River water contains approximately 1.0 mg/L of fluoride. No VOCs have been detected in treated water. Detailed quarterly results of Seattle water quality analyses are presented in the Appendix. 3-12 Lead and copper monitoring was also conducted throughout the entire Seattle service area in 1997. The Regional Monitoring Program for lead and copper testing includes purveyors such as Tukwila. Results of this monitoring indicated that neither the copper nor the lead action level was exceeded for water samples taken from the Cedar River distribution system. However, the 90th percentile level for lead throughout the entire Seattle distribution system exceeded the action level for lead. This is due to higher lead levels in samples collected in homes served by the Tolt supply. Lead and copper testing by Seattle in 1992 yielded similar results. Seattle treats raw Cedar River water with a lime slurry at the Lake Youngs Treatment Plant to increase pH and reduce corrosivity. Although increasing the treated water pH may result in increased THM concentrations, excessive TTHM concentrations have not been a water quality problem in the past. Compliance with the proposed Stage 2 D/DBP Rule with a 40 µg/L MCL for THMs may also be a concern in the future. Lead and copper test results for Seattle are included in the water quality section of the Appendix. FACILITY ANALYSIS Source of Supply Analysis The source of supply analysis is based on source availability and reliability. Source Availability The path of water from the City of Seattle to the City of Tukwila is as follows: • Seventy Percent of the City of Seattle's water supply originates in the Cedar River Basin and is stored behind the Masonry Dam at Chester Morse Lake. Except under emergency situations, Tukwila's water supply comes from the Cedar River Supply System. • Water released from Chester Morse Lake is diverted from the Cedar River and is treated with fluoride and chlorine at the Landsburg Diversion Station. • Treated water is conveyed from Landsburg to the Lake Youngs Regulating Basin through two 78" pipes called the Lake Youngs Supply Lines #4 and #5. Lake Youngs has a maximum water elevation of 493 feet and is usually kept within five feet of this elevation. If Lake Youngs must be taken out of service, the Lake Youngs Bypass lines convey water around Lake Youngs to Seattle and its customers. • Water at Lake Youngs is again treated with chlorine for disinfection and is also injected with lime for pH control. Treated water is gravity fed to the first customers through the. 96" Cedar River Tunnel. • The Cedar River Tunnel splits into two lines at the surge tanks and then into four lines at the Control Works near Renton. These four lines are the Cedar River Pipelines (CRPL) 1, 2, 3, and 4. • CRPL 4 diverges from the other three pipelines and passes through the southerly portion of Tukwila. The West Seattle Pipeline (WSPL) branches off CRPL 3 near Tukwila's Allentown neighborhood. Tukwila's main supply stations are tapped off the WSPL and off CRPL 3 and 4. 3-13 Currently, the City has only the North Hill Reservoir serving customers in its water service area. Increased demands are mostly supplied by each supply station. As discussed in Chapters 1 and 2, the North Hill Reservoir has a capacity of 2 MG and has two sets of pumps which are configured to pump to two separate pressure zones. The High Zone (400 foot HGL) pumps are regulated by a variable frequency drive (VFD) and are running constantly. The Low Zone pumps supplement pressures in the main 360 pressure zone and are only used during periods of high demand. The equations used in calculating the storage requirements are discussed in the next sections, followed by Table 3-5, which presents a summary of the storage analysis results.

However, because Tukwila is part of a consecutive water supply system, DOH does not require the City to have equalizing storage. A consecutive water system is defined as a water system that purchases water from another regulated water system. The DOH Waterworks Standards manual Section 9.2.7 allows consecutive systems to utilize the supplying systems storage availability to satisfy equalizing storage requirements as long as the following criteria are fulfilled: 3-15 1. The wholesale water agreement between the supplying system and the consecutive system defines the quantity of storage that is available to consecutive system. 2. It can be demonstrated that the supplying system can maintain a system wide 20 psi pressure under required fireflow conditions while the consecutive system maintains a system wide pressure of 30 psi under peak hour purchase conditions. 3. It can be demonstrated that the consecutive system can maintain a system wide 20 psi pressure under required fireflow conditions while the supplying system maintains a system wide pressure of 30 psi under peak hour purchase conditions. Because Tukwila does not have any limitations on the amount of water it can draw from Seattle, the City's storage requirements can be met by Seattle's supply system. However, Tukwila is penalized by Seattle for creating excessive peak demands, and it is the goal of Tukwila to manage their existing water system in order to reduce or eliminate peak demand charges. If DOH determines in the future that Seattle's storage availability is overextended and not reliable, Tukwila may be required to construct more storage. The following equations can serve as a basis for future storage calculations. Standby Storage The minimum required standby storage is calculated using the following equation: VsB = 2(ADP) VSB = Required standby storage component (gallons) ADP = Average daily purchase for the design year (gallons) Standby storage is used to provide a measure of reliability should the City's source of supply fail or unusual conditions create increased system demands. The standby storage component contributes the highest volume to the storage analysis. The standby storage was calculated using the average day purchase of 2.55 MGD, 2.83 MGD, and 3.47 MGD for the years 1997, 2003, and 2017, respectively. Fire Suppression Storage The minimum fire suppression storage volume is calculated using the following equation: VFss = NFF x T NFF = Needed fire flow, in gpm T = Duration of NFF, in minutes The fire suppression storage requirement varies with each of the City's pressure zones. The Upper Ryan Hill Zone and the North Hill Zone are primarily single family residences with some multi -family residences for which the City needs to provide 1,000 gpm for 1 hour. The level of service for the Southcenter commercial area and the Boeing Field industrial area is 1,500 gpm for 3 hours. 3-16 As stated previously, there is no contractual limit on the quantity of water which Tukwila can withdraw from the Seattle system. Similarly, there are no restrictions on the rate at which Tukwila can withdraw water from the Seattle system. Therefore, aside from the 2 MG of storage on North Hill, Tukwila primarily relies of Seattle to fulfill its storage requirements. However, this reliance can create a storage deficiency for Tukwila which can result in demand charges being levied against Tukwila by Seattle. Storage Deficiency Demand Charge As discussed previously, demand charges are assessed against the City when the ratio of the 15 -minute peak flow to the 24-hour flow during that day is greater than 1.3. This ratio is averaged over the ten largest purchase days during the summer months. The demand charge is calculated each fall and added as a flat charge for each month during the next year. The 1997 Demand Metering Report issued by Seattle indicates that the highest peaking factor of 1.73 is achieved in the Ryan Hill area (CRPL 3 line segment). However, because the purchased quantity of water is so low at Supply Station 169, the demand charge at this line segment accounts for less than 6% of the total demand charge for 1997. Maximum flow volumes through Supply Stations 10 and 11 (WSPL line segment) are over ten times greater than flow volumes through Supply Station 169. This line segment, however accrued no demand charge in 1997 because the calculated demand factor of 1.10 is significantly less than 1.3. These numbers are somewhat expected since the WSPL line segment primarily supplies water services in Boeing Field and industrial areas in the north end of the City limits. Customers in these areas are predominantly in the Commercial/Industrial customer class which historically have much lower peak hour demands than residential areas. This hypothesis is supported clearly by demand data from the Ryan Hill area where water services are primarily for single family residents. Therefore, the bulk of Tukwila's demand metering charges come from the CRPL 4 line segment which serves Supply Stations 13, 14, 15, and 16. The average demand factor for this line segment for 1997 is 1.34. Although demand factors for each supply station vary between 0.00 (SS14) and 20.94 (SS16), Supply Station 13 is the largest contributor to Tukwila's demand charge. This is because over 90% of the maximum flow volume on this line segment comes from this supply station. As discussed previously, SS13 and SS15 largely supply the Tukwila Urban Center and the residents in and around North Hill. SS14 is not currently in use and SS16 supplies water to the small amount of residences in the 380 Crystal Springs Zone. In 1996 and 1997, demand charges amounted to $2,455.06 and $6,627.62 per month respectively based on 1995 and 1996 demand parameters. Demand charges for 1997 to be applied in 1998 amount to $5,061.44 per month. The demand charge per 1,000 gallons of deficient storage increased from $19.10 in 1996 to $21.10 in 1997 and remains at this rate currently. 3-17 Storage Use As mentioned previously, the North Hill Reservoir is used to supplement pressures in the main 360 Zone during peak demand periods. This method of pumping helps reduce the 15 -minute peaks and can significantly reduce the City's average demand factor. When demands drop off at night or in the afternoon, the reservoir is put in the fill cycle. However, the Low Zone pumps are not regulated by a variable frequency drive (VFD) and therefore can only run at full output. This current scenario does not make the most efficient use of the reservoir or the pumps since small pressure decreases can only be mitigated by full pump output. This causes the pumps to pump in circles by recirculating water back to the reservoir. The pumps also kick the supply station PRVs out of flow control mode and into pressure control mode. This mode of operation allows the PRVs to supply water as needed in order to maintain a set constant pressure. This can also result in demand charges as system needs are met. The City has recently installed a Cla-valve pump control system in an attempt to mitigate this problem. Table 3-5 presents the storage requirements for the City of Tukwila based on the DOH requirements discussed previously. Because Tukwila is part of a consecutive water system, there is no requirement to construct more storage facilities for the City's water service area. However, these calculations can serve as a basis for future storage requirements should DOH determine that the Seattle system is unreliable. Operations Analysis The City uses a SCADA system to monitor, control, and document daily system conditions. The system is located at the City's Water Operations shop on Minkler Blvd. and monitors system parameters such as flow and pressure. Currently the City has installed telemetry at Supply Stations 11, 13, and 15 and also has telemetry at the North Hill Reservoir. Inflow and outflow conditions at the reservoir are monitored through telemetry as well as reservoir level. Flow trends can be established using telemetry records and daily demand curves can also be created using hourly flow measurements at the telemetered supply stations. The telemetry system is further detailed in the City's Operations and Maintenance manual which was prepared by the City in 1992. The City is currently updating this manual as a separate document from this report. 3-18 CHAPTER 4 HYDRAULIC ANALYSIS The operation of a municipal water system such as the City of Tukwila's involves dynamic interactions between various water system components, including source, storage, transmission, and distribution system facilities. These interactions and their effect on the level of service provided to the City's customers are dependent on the distribution and magnitude of water demands within the system and the performance characteristics of the water system. In addition to normal diurnal demands, infrequent demand events, such as fires, can create significant stress on a municipal water system. Such factors must be considered in analyzing the ability of a water system to provide for future demands while maintaining an adequate level of service to its customers. The development of a computer hydraulic model, which can accurately simulate the response of a water system under a variety of conditions, has become an increasingly important element in the planning, design, and analysis of municipal water systems. The Washington State Department of Health's WAC 246-290 requires hydraulic modeling as a component of water system comprehensive plans. This chapter presents the development and use a of computer hydraulic model for the City's water system. HYDRAULIC MODELING PROGRAM The City of Tukwila's hydraulic model was constructed with Haestad Method's WaterCAD hydraulic modeling software which is configured with a graphical user interface. Each model element, including pipes, valves, pumps, and tanks, is assigned a unique graphical representation within the program. Each element is also assigned a number of attributes specific to its function and representation. Typical element attributes include spatial coordinates, elevation, water demand, pipe length, diameter, and pipe status (open or closed), as well as pump and tank characteristics. Model input is accomplished through the creation and manipulation of these objects and their attributes. The WaterCAD modeling package also includes a number of tools which facilitate the presentation of model results. The results for a given simulation can be presented in either graphical or tabular report format to indicate flow, demand, pressure, head loss, and hydraulic grade for various system elements. HYDRAULIC MODEL DEVELOPMENT One of the primary steps in the implementation of the City's hydraulic model was the creation of the model itself as a realistic representation of the current Tukwila water system. Model input and layout was transferred from the City's water system basemap provided through the 1991 Water System Comprehensive Plan and updated with information supplied by the City's Public Works Department. The hydraulic model includes elements representing pipes, tanks, valves, and junction nodes, which establish points of connections between pipes. In general, only water mains that were six inches in diameter or larger were modeled. Four -inch diameter mains were modeled only in areas of the water system where pipes six inches or larger were generally not present. 4-1 A hydraulic model node map indicating pipe location, size, and model number, as well as node location and model number is provided in a jacket in the back of the plan. The hydraulic model includes many pipes which are located on private property and are consequently not the responsibility of the City of Tukwila. These privately owned and maintained water lines are included in the model to facilitate an evaluation of the level of fire protection at schools, apartment complexes, and commercial developments where fireflow would most likely be obtained from private fire hydrants on private water lines. HYDRAULIC MODEL DEMANDS The WaterCAD hydraulic modeling software allows the user to create different demand scenarios for use in the various hydraulic analyses. For the purposes of this Plan, the following demand scenarios were developed in the hydraulic model: • 1997 Average Daily Demand (ADD): These demands were used for model calibration and for verification of existing conditions. • 2017 Peak Day Demand (PDD): These demands were used for system analysis under fireflow conditions. • 2003 and 2017 Peak Hour Demand (PHD): These demands were used for system analysis and to develop the six-year and twenty-year Capital Facilities Plan. The City of Tukwila water service area consists of residential customers and commercial/industrial users. Current and projected water demands were distributed based on zoning designations. The demands of large water users were applied at the nodes closest to their actual addresses based on actual consumption records provided by the City's Water Utility Billing Department. MODEL CALIBRATION Once the demand scenarios are established, the final step in the development of the hydraulic model is calibration. The calibration of a hydraulic model provides a measure of assurance that the model is an accurate representation of the actual system. For the City of Tukwila's hydraulic model, field measurements provided by City staff and Gray and Osborne personnel were used to complete the calibration process. Fireflow Tests Recent hydrant fireflow tests were conducted by Gray & Osborne in conjunction with the City. Fireflow tests were performed in April 1997 by Gray & Osborne and the City of Tukwila staff after completing the water main installation project in the Allentown area. The most recent tests were performed by Gray & Osborne personnel and City staff in February 1998. For each fire hydrant test, measurements were taken for static pressure, residual pressure, and the hydrant flow rate at residual pressure. Pressure measurements were taken using a pressure gauge and hydrant flow rates were calculated using pressure readings from a pitot gauge. These results were used to check the accuracy of the model 4-2 input data and to calibrate the model through adjustment of pipeline roughness coefficients and system elevations. Since the actual conditions of the system at the time of each hydrant test is unknown, the model was run under 1997 average day demand conditions. Also, pressure and flow values at the supply stations during each fireflow test were available through historical telemetry records. These conditions were also set during each calibration run. Table 4-1 shows the static pressure model calibration results. The test at hydrant 62A was a static reading only and does not have any flow pressures and volumes associated with it.

If the pressure differential between field measurements and model results were over five psi, the model is checked for accuracy of node elevations, pipe connectivity, and if necessary, pipe roughness coefficients are adjusted. After a number of model runs, the roughness coefficient was adjusted to a roughness coefficient of 130. Table 4-2 shows the residual pressure model calibration results. MODEL SIMULATIONS AND RESULTS The Tukwila master meters are located in several locations throughout the City limits. These supply stations were all modeled as open reservoirs with hydraulic grade lines (HGL) of 465 feet in order to simulate the hydraulics of Lake Youngs Reservoir. Each supply station reservoir in the model is then run through a PRV with pressure settings that replicate each supply station's elevation and reduced pressure.

Supply Station 16 serves the Crystal Springs 380 Zone and Supply Station 14 is not currently active. Supply Station 6 serves the residences in the Ryan Hill area. Pressures at the discharge side of each PRV for each supply station is shown on the Water System Basemap and on the Pipe and Node Map, both included in the Appendix. The North Hill Zone maintains a hydraulic grade line of 400 feet through two vertical turbine pumps located at the North Hill Reservoir. These pumps are equipped with a variable frequency drive (VFD), and were simulated in the model by inserting a pressure sustaining valve (PSV) on the discharge side of the pumps. This feature maintains a set HGL on the discharge side of the pumps and vents any remaining pump flow back to the reservoir. Hydraulic model analyses were conducted to simulate the response of the City of Tukwila water system under a variety of conditions including peak hour and fireflow demands. Model runs using 2017 peak hour demand conditions in the absence of fireflow were conducted in order to check the system for low pressures and high excessive pipe velocities. At 2017 peak hour demands, the highest pipe velocity in the Tukwila distribution system was along the 12 -inch water main in Pacific Highway S. Pipe velocities in this line segment were calculated at approximately six feet per second. This is below the recommended maximum design velocity of 8.0 feet per second and is a good indication of the overall strength of the pipe network. The 20 lowest pressures and the corresponding nodes are shown in Table 4-3. Also shown in this table is the location of the lowest pressure nodes and the corresponding zoning designation. As shown in Table 4-3, the 20 lowest pressures under 2017 Peak Hour Purchase conditions are all above the DOH minimum pressure requirement of 30 psi. Most of the lowest pressures are in the North Hill and Ryan Hill residential areas of Tukwila. Both of these areas have the highest elevations within the City limits which results in lower pressures than similar areas at lower elevations. Model runs for this demand scenario are included in the Appendix. 4-4 TABLE 4-3 2017 PEAK HOUR DEMAND'/ LOWEST SYSTEM PRESSURES Junction Node Number Minimum Pressure (psi) Location .

The system is required to provide at least 20 psi during peak day demand with a fireflow. Fireflows were modeled at all node locations within the Tukwila City limits and the lowest system pressures were indicated by the hydraulic model. Required fireflows are based on the Uniform Fire Code (UFC) and the requirements and codes of the City of Tukwila Fire Department. Fireflow requirements for the City's water service area are generally 1,000 gpm at 20 psi for single family residential areas. Fireflow requirements for multi -family, commercial, and industrial areas are based on building type and building size according to the UFC. However, the City requires any building that is over 10,000 square feet, has five or more living units, or has three or more levels to install fire sprinklers for fire prevention. This requirement was passed into law in 1995 as Ordinance 1742 and it applies to most structures in the C/I/MFR zoning category. Any structure that contains fire sprinkler systems may have its fireflow requirements reduced by 75%. Under no circumstances will fireflow 4-5 requirements be reduced below a minimum of 1,500 gpm for buildings other than single family residences. Since the City has several different pressure zones and supply areas, the hydraulic model has been run under several scenarios. These scenarios represent fireflow demands in different zones of the City's water service area. For example, fireflow conditions in Ryan Hill were run separate from the rest of the system since the water system and supply stations are independent of other areas of the Tukwila water system. A similar scenario was set up for the North Hill High Zone which is separated from the main pressure zone by one-way check valves. Since there are also different fireflow requirements in different areas of the City, Junction Nodes were relabeled to represent their location in the City water system. Junctions in the North Hill high pressure zone have an "N" or "n" prefix representing single family and multi -family zoning respectively. Other junctions in single family zones such as Ryan Hill and Allentown are labeled with an "SF" prefix. The remainder of the junctions in the commercial, industrial, or multi -family zones are labeled with a "J" prefix. The hydraulic model was run under 2017 peak day demand conditions with appropriate minimum fireflow requirements at each node. The model goes through a series of iterations until it determines the maximum fireflow that the system can support at the specified location while maintaining 20 psi throughout the system. Table 4-4 provides the available fireflow as determined in the hydraulic model and resulting pressure at the node. In some cases, the pressure at the node providing the fireflow is not the limiting element in the amount of fireflow available. Therefore, the minimum pressure in the Zone is also reported along with the corresponding node. Table 4-4 is a sample of locations representing some of the lowest available fireflows throughout the City. As shown in Table 4-4, the City has minor fireflow deficiencies at several locations, all of which are located on mains that dead end on the isolation valves around the Upper North Hill Zone or the Crystal Springs Zone. The remaining junctions shown in Table 4-4 demonstrate that the City has more than adequate fireflow capabilities in commercial, industrial, and residential zones. Results from fireflow model runs for 2017 are included in the Appendix. Nodes associated with water mains 4 -inches or less in diameter are not reported here because they are not suitable for carrying fireflow. Distribution lines of this size are found in unimproved areas of Fort Dent and in some areas of Allentown and Ryan Hill. These areas can achieve higher fireflows if water mains are upsized and looped. This is discussed further in Chapter 6, Recommendations and Improvement Program. 4-6 TABLE 4-4 2017 PEAK DAY DEMAND WITH FIREFLOW 'Junction ' :: Node Number Location ,.:Required `' Fii eflow ' (gpm) :Available Fireflow (gpm) ; '., Residual Pressure at .

Several areas with small diameter pipes show inadequate fireflow capacity and excessive pipe velocities. Pipes which are not looped or which dead end on check valves also do not have adequate pressures under peak day and fireflow demands. These areas do not occur often throughout the City's water service area and are addressed further in Chapter 6. The current hydraulic model represents the City's current service area and distribution system. Should the City decide to make improvements to the distribution system, these changes should be made in the model and their effects should be analyzed. When the City decides to take over portions of KCWD 125, the model should also be reevaluated to determine the hydraulic requirements of this system and the potential results of this takeover. 4-7 CHAPTER 5 CONSERVATION PROGRAM AND WATER RIGHTS ANALYSIS The objectives of this chapter are to develop a conservation program and evaluate existing conservation efforts. Conservation programs are necessary to promote efficient water use and ensure that adequate water rights are available for existing and future system demands. Two broad based elements will be developed in this chapter: • Conservation Program Development and Implementation • Water Rights Evaluation and Source of Supply Analysis The Conservation Planning Requirements were published by the Department of Health (DOH) in March 1994. Development and implementation of a conservation program is required for both approval of the Water System Comprehensive Plan and when applying for new water rights from the Washington State Department of Ecology. The Conservation Planning Requirements presents guidelines for public water systems regarding water use reporting, demand forecasting methodology, and conservation programs. This document establishes various conservation implementation requirements based on the number of connections served by the water system. The water use data and water demand forecasts have been evaluated and are presented in Chapter 2. The Conservation Program includes an evaluation of Conservation Plan elements required or recommended by DOH. A water rights evaluation is necessary to determine if the existing water rights are adequate to meet the future needs of the water system as determined by the water demand forecasting. If existing water rights are not adequate, efforts must be made to secure additional water rights and evaluate methods of optimizing the existing sources of supply through a source of supply analysis. A source of supply analysis is required for all systems pursuing water rights within ten years of approval of their water system plan. For systems not pursuing water rights, a source of supply analysis is also recommended, but not required. Since the City of Tukwila is part of a consecutive water system and does not currently hold any water rights of its own, and because the City of Seattle encourages its wholesale customers to follow its conservation program, the City of Seattle's water rights and conservation program are also discussed. CITY OF SEATTLE CONSERVATION PROGRAM The City of Seattle adopted a water conservation plan as part of their 1994 Water System Plan Update. Among the goals of this plan were to deliver a regional conservation message and to reduce program costs due to duplication of conservation actions by wholesale customers. In their effort to meet these goals, the City of Seattle sought to coordinate activities and share information with wholesale customers like the City of Tukwila. Seattle continues to organize conservation meetings with its purveyors on a monthly basis where conservation goals and ideas are exchanged and program changes are discussed. 5-1 The Water Smart Technology Program was started in 1994 and is targeted at commercial and industrial customers. Rebates are offered by Seattle to its direct customers, as well as to purveyor customers who are interested in installing low-water use appliances such as refrigerators, ice machines, and air-conditioning systems. Interested customers can apply directly to Seattle for a rebate or cost-sharing grant and, if eligible, can qualify for receiving up to 50% of the installation costs from SPU. Seattle coordinates all of the promotion efforts for this program and encourages participation from all of its wholesale customers. Although the response from Tukwila customers has not been significant, the program overall has been very successful throughout the Seattle area. The Laundrywise conservation program was just instigated in June 1998 and is intended to award rebates for installing water -saving clothes -washing machines. The program is aimed at multi -family dwellings only, such as apartments and condominiums, and specifically targets coin-operated machines in residences that have shared laundry facilities. Flat rebates are offered by Seattle, who again manages the implementation and marketing of this program. CITY OF TUKWILA CONSERVATION PROGRAM WATER USE DATA COLLECTION REQUIREMENTS The water use data collection requirements for the City of Tukwila established in DOH's Conservation Planning Requirements are summarized in Table 5-1. WATER USE PATTERNS Identifying water use trends is an important part of understanding water supply system operation and implementing conservation programs. Demand patterns vary not only throughout different times of the year but also throughout each day. Understanding system needs assists water operators and public works staff in making system adjustments and solving demand oriented problems within the system. As discussed previously, demands throughout the system vary by zoning designation, with customers in the Commercial/Industrial (C/I) class accounting for over 70% of water demand on an average annual basis. However, as discussed in Chapter 3, industrial demands in the northern part of the City are usually fairly consistent during business hours and do not contribute significantly to peak hour demands and subsequent demand metering charges. Commercial and light industrial customers in the Tukwila Urban Center (TUC) create the most significant peak day demands throughout the water system. Again, although the peak hour demands create an average demand factor of only 1.34, the volume of water consumed in the TUC contributes to over 90% of the demand charges levied by Seattle. 5-3 TABLE 5-1 DOH WATER USE DATA COLLECTION REQUIREMENTS FOR TUKWILA Water-Use'Datk; 'Requireinenta' •City's Status Source of Supply Meter Readings [1] Read daily but Report Only Monthly and Annual Totals City Telemetry Monitors Daily Master Meter Readings Wholesale amount purchased Collect Monthly Total Monthly Totals are Collected by Seattle Service Meter Readings Collect Monthly Totals [3] Monthly Totals are Collected by Tukwila Unaccounted for Water (non- revenue) [2] Collect Annual Total [3] Compiled Annually Accounted for Water (non -revenue) Collect Annual Total [3] Not Applicable Peak Day/Peak Month Collect Each Year's Peak Day and Peak Month Totals Available but Not Compiled Population Served Estimate Annual Total Estimated Annually Economic Data Existing Water Rates Water Rates Established Conservation Data [4] Collect Once Per Year Not Currently Available Source: Notes: DOE/DOH Conservation Planning Requirements, March 1994. [1 ] Those systems which do not have source meters will be required to estimate source production. [2] Unaccounted for water is that which is lost through leaks, evaporation, or use that is not recorded and/or accounted for. Non -revenue water that is accounted for, such as fire protection can be estimated and should not be included in the unaccounted for estimated. [3] Calculation of non -revenue water and service meter usage is dependent upon staff resources and the availability of service meters in areas not in CWSSAs. If a water system is located in a CWSSA, the information will be required. [4] Conservation data is not required to be reported annually but will be used by the water system in calculating a demand forecast. It will be required in water system plans or as a part of an application for a water right. Although residential demands account for less than 30% of average day demands, they often contribute significantly to peak day and peak hour demands. This can be attributed to increased irrigation in the summer months and concentrated household water demands before and after traditional work hours. Tukwila's increased residential water demands are apparent from analyzing demand data from areas that are predominantly residential. Supply Stations 169 and 16 serve the Ryan Hill and Crystal Springs areas of Tukwila respectively, both of which are primarily single family and multi -family residences. Although total demands in these areas are small, peak hour demands can be 1.5 to 50 times greater than peak day demands, yielding significant demand factors for these supply stations. Because peak day volumes are low, demand charges in these areas are also low. However, City conservation efforts should continue to target specific residential and commercial uses in order to reduce peak day and peak hour demands. These efforts are discussed in the following sections. RECOMMENDED CONSERVATION MEASURES Table 5-2 shows the conservation measures recommended by DOH for systems serving 1,000 to 25,000 connections. 5-4 TABLE 5-2 DOH RECOMMENDED WATER CONSERVATION ELEMENTS FOR SYSTEMS WITH 1,000 TO 25,000 SERVICES :: rElement � `< J ;. ecoinrnen046*40.iectiveia ''' ; 'City Vf 3 ilk Policy, Program Promotion Publicize the need for water conservation through television and radio public service announcements, news articles, public water system bill inserts, or other means.

Service Meters Install individual service meters for all water users. Maintain periodic meter testing and repair program. All water users are metered. Meters are maintained by Tukwila. Unaccounted Water/Leak Detection Conduct a regular and systematic program of finding and repairing leaks in system mains and laterals. This includes on-site testing using computer-assisted leak detection equipment on water distribution mains, valves, services, and meters. City of Tukwila operations personnel monitor the system for leaks. Leak detection surveys have been initiated. 5-5 TABLE 5-2 (CONT.)

Devices in kits could include shower flow restrictors, toilet tank water displacement devices, leak detection dye tablets, informational brochures, and other materials. • The City works in conjunction with Seattle to identify Tukwila customers that are eligible for discounted low -flow devices and supplying them with these devices. Nurseries / Agriculture Encourage and/or require the application of current technology to water use practices of large agriculture/irrigation operations. Examples include nurseries and commercial agriculture. Moisture sensors, flow timers, low volume sprinklers, drip irrigation, weather monitoring, and other practices to increase irrigation efficiency could be installed. Tukwila's public golf course currently irrigates with untreated river water. The City is also developing water reuse for this application. Landscape Management/ Playfields - Xeriscaping Promote low water demand landscaping in all retaill customer classes (private, public, commercial, industrial, etc.). Work with local nurseries to ensure the availability of plants that achieve this objective. The City coordinates efforts with retail customer landscaping and water usage restrictions. Conservation Pricing Implement rate design techniques to provide economic incentives to conserve water. Conservation pricing has been implemented by the City. Source: DOE/DOH Conservation Planning Requirements, March 1994. WATER DEMAND FORECAST Water demand forecasts, presented in Chapter 2, are based on population estimates and forecasts determined from the FAZ and TAZ models. The current service area population is 5,626 and the existing per capita water usage is 78.2 gpcd, excluding commercial and industrial use. The water use projections indicate an increase from 11,368 ERUs in 1997 to 19,742 ERUs in 2017. Further details on how these demand forecasts were established are presented in Chapter 2. CURRENT CITY OF TUKWILA CONSERVATION MEASURES The City of Tukwila current per capita water demand is 78.2 gpcd with a peaking factor of 1.83 from average day to peak day demand. As discussed in Chapter 2, the per capita demand number does not include commercial and industrial water use because of the 5-6 disproportionate use by this customer class. Per capita demand also does not include lost and unaccounted for water. The percentage of production of lost and unaccounted for water is 21.2% for 1997. Lost and unaccounted for water is usually not considered a problem until it exceeds fifteen percent of water production and is not required by DOH to be remedied until it reaches twenty percent. Although the City has been aggressively trying to reduce lost and unaccounted for water through leak detection surveys and replacing old water mains, another leak detection survey will likely be pursued by the City. However, the City of Tukwila currently utilizes several conservation measures in an attempt to reduce per capita consumption and any demand metering charges that can be accrued during the year. Distribution System Measures • Source Meters - Water from the Seattle water system enters the City of Tukwila through master meters located at each supply station. These are calibrated, maintained, and read by Seattle Public Utilities (SPU) staff. • Service Meters - All water users have individual service meters. Meters are inspected regularly and repaired or calibrated as necessary. Damaged meters are replaced as soon as they are discovered. • Unaccounted for Water / Leak Detection - Leaks in the system mains or laterals are repaired as soon as they are discovered. Chronically leaking and old pipes are replaced on a routine, proactive basis. The City also requires permits and meters for hydrant use as a means of conservation and tracking water use. • Water Line Looping - The City has been replacing old and undersized water mains on a proactive basis and has been analyzing areas which may have inadequate pressure or supply. Whenever possible, the City has attempted to create loops within the water lines in order to promote better supply and a more flexible system. This technique also promotes water savings by reducing the need for flushing dead end water lines which may not get proper circulation during general use. Public Education/Program Promotion/Public Assistance • Water conservation materials published by the City of Seattle and DOH are made available to the public at City Hall. These materials have included lawn watering schedules, water conservation tips, water conservation posters, and information on water saving devices for the home. • City staff also observe customer consumption rates while reading meters in the field. Residential customers with unusually high demands are left door hangers informing them of a noticeable increase in water use. Commercial and industrial customers receive a phone call informing them of unusual water consumption. City staff will also assist customers in locating potential leaks. In the past, the City has also worked closely on conservation efforts with commercial customers in the Southcenter area. Because irrigation accounts for a significant portion of water use, the City has negotiated landscaping issues with customers to achieve water use reduction and still maintain customer satisfaction. 5-7 Water Rate Structuring • The City currently has water billing rates that are intended to encourage conservation. The billing rate is structured such that consumption during the summer months is billed at a higher rate than consumption during remaining months. Billing rates for commercial/industrial (C/I) customers are slightly higher than the rates for single and multi -family (SFR/MFR) residential consumers during the same time of year. Rates during the 1997/1998 and the 1996/1997 billing year are shown in Table 5-3. • The City also bills commercial and multi -family customers for sewer services based on water use. City sewer charges for commercial/industrial accounts are $10.00 per 750 cf of water consumption at each account. METRO charges for commercial/industrial and multi -family accounts are structured similarly. By billing customers for sewer in direct proportion to water use, customers have a greater incentive to conserve water when they can save money on both utility bills. Large Irrigation Users • In addition to the conservation measures implemented by the City, the Tukwila Public Golf Course only uses City water for potable water facilities and does not use any City water for irrigation. The golf course has a pumping system in place that draws water directly from the Duwamish River for irrigation. Although this is not a metered use, it is estimated that this saves over 40 million gallons each year in consumption.

In 1993, the City was involved in a project sponsored by METRO which constructed 1,700 feet of 16" water reuse pipe. The pipe extends from the Renton wastewater treatment plant (WWTP) along the Burlington Northern Railroad and Interurban Corridor up to Fort Dent Park. METRO completed the original EIS with the intent of irrigating the Fort Dent Golf Course with treated wastewater effluent. Irrigation water currently used at the golf course is estimated to be approximately 40 million gallons annually. The City and King County/METRO anticipate that this portion of the reuse project should happen during 1998. Plans are currently being made to also irrigate Fort Dent Park and the Fairway Center Office Complex south of the golf course. Both of these areas are currently served 5-8 by Tukwila, and the City estimates that together they use approximately seven million gallons per year for irrigation purposes. King County/METRO anticipates having a connection made for these customers within the next year. In 1995, when the City took over water service to the Boeing Field area, a new 18 -inch ductile iron pipe was laid adjacent to Seattle's existing 21 -inch steel pipe. The City decided at that time that the existing water main would be abandoned in place for possible future use as a water reuse line. Seattle has turned the abandoned pipe over to Tukwila and it is an excellent asset for industrial and irrigation water reuse for Boeing Field customers. There is also a 96 -inch water reuse line along West Marginal Place in Tukwila's industrial area that is currently being used by King County/METRO. This is also an asset to the City's future reuse capabilities, and it can be used in conjunction with the abandoned line in E Marginal Way or with the water reuse line along the Interurban Corridor. All of these options require significant planning and capital investment, and the City is actively pursuing them in coordination with King County/METRO and other neighboring utilities. ADDITIONAL CONSERVATION MEASURES FOR CONSIDERATION One method of determining conservation program measures that are successful in reducing the amount of water consumption is to look at the types of programs that have been successful in other cities. The City of Seattle has developed a very successful conservation program. Several elements of Seattle's program may also be beneficial to the City of Tukwila, some of which are discussed in the following section. WATER SAVING DEVICES The City of Seattle instigated the Home Water Savers Program in 1992 after eighteen months of program planning and testing. Water savings devices were distributed to over 300,000 single family houses during the summer months as part of a collaborative effort with several other local utilities. Devices were distributed free of charge and included a 1.5 gpm faucet aerator, a 2.5 gpm showerhead, and displacement devices for toilets. As part of this same program, 65,000 multi -family units were fitted with low -flow shower heads and faucet aerators and 5,000 low -flow showerheads were installed in regional gyms and dormitories. Program savings are estimated at almost five MGD at a cost of $.32/ccf. This program has proven effective in many other communities in the Puget Sound area and has received support from utilities and customers alike. Follow-up studies on the Seattle program indicated that over 65% of households had installed the low -flow showerheads. Water saving devices can be distributed free or can also be offered at cost to customers through the City's public works department. Advertisements and information can be provided through bill stuffers, newspaper ads, and notices in public areas. 5-9 LOW -FLOW TOILET PROGRAMS Residential Efficient Toilet Promotion The City of Seattle conducted a marketing campaign in 1994 to encourage residential customers to replace their existing toilets with more efficient models. Current statewide building codes specify that only toilets which use less than 1.6 gallons per flush (gpf) can be sold or installed. Through videos, brochures, bill stuffers, and newspaper articles, Seattle promoted retrofitting toilets in residential homes as an efficient conservation method. Although the costs for this program were minimal, its effectiveness has not yet been determined by Seattle. Commercial Toilet Retrofit Program The City of Seattle also implemented a program in which commercial water customers could apply for a rebate on installed low -flow toilets and urinals. This program was pilot -tested in 1994 and continued through 1997. Eligible applicants must be commercial water customers with existing fixtures that use 3.5 gallons per flush (gpf) and are flushed a minimum of 30 times per day. Approved applicants receive $150 for installing each 1.6 gpf tank type toilet and $150 each for flush valve fixtures (1.6 gpf toilets and 1.0 gpf or less urinals). The program is projected to save over 1.1 MGD at a levelized cost of $0.76/ccf. WATER RIGHT EVALUATION AND SOURCE OF SUPPLY ANALYSIS As mentioned in Chapter 1, Seattle has a water right claim filed with DOE for the Cedar River Watershed area. The water right claim designates a water storage right as well as a water diversion right and also delineates the watershed area which the City owns. The City first began diverting water from the Cedar River for drinking water purposes in 1901. The Masonry Dam (built in 1914) was designed to increase the City's storage capabilities in the drier months to over 160,000 acre-feet. This is the amount of storage right that Seattle has claimed, although they presently use less than half of this. The quantity of water claimed by Seattle is defined by an average diversion of 366,660 acre- feet annually. This equates to 300 MGD or 465 cubic feet per second (cfs). Presently Seattle only withdraws an annual average of 137 MGD from the Cedar River although this rate can increase to approximately 220 MGD during summer months. Current treatment and transmission capabilities limit Seattle's ability to draw water at rates much higher than this. Treatment capabilities at Lake Youngs also prevent Seattle from feeding water to its water service areas at rates higher than 220 MGD. None of these limiting factors have presented a problem for Seattle in fulfilling its purveyor obligations or for other purveyors fulfilling their commitments to their customers. Seattle currently relies on four transmission lines (Cedar River Pipelines) to deliver water to Seattle's water service area. Projected demands by Tukwila under the 2003 and 2017 average day, peak day, and peak hour scenarios will not exceed the capacity of Seattle's existing transmission system. However, due to the limitations of current water treatment 5-10 facilities and also due to upcoming capital improvements, wholesale water costs and demand metering costs will undoubtedly be increasing over the next fifteen years. In order to be better prepared for this, Seattle has implemented a variety of conservation measures during the past ten years that intend to reduce the demands placed on Seattle's water system. As mentioned previously, Tukwila has also been promoting conservation programs in an effort to reduce their water demands and water costs. In addition, Seattle has indicated that it will not be renewing purveyor contracts when they expire in 2012. This initiative is intended to encourage independence among water utilities and to support the formation of the Cascade Water Alliance (CWA). The CWA is an organization that is being formed in conjunction with SPU in order to replace Seattle as a supplier to the 26 purveyors that it currently sells to. In doing so, these utilities will be buying water from CWA instead of Seattle, and CWA will be responsible for supplying the growth needs of the purveyors in the future. This will allow purveyors to have more input into decisions that are made regarding water supply issues and will remove Seattle from the position of having to obtain new water rights to supply future purveyor growth. If Tukwila chooses to join CWA in the future, initiating conservation programs now will help reduce water system demands in the future. This in turn may help reduce the costs associated with storage, water treatment, and source development. SUMMARY AND CONCLUSIONS Because lost and unaccounted for water averages around 20% of production, The City should initiate another leak detection survey. DOH requires lost and unaccounted for water to be at or below 15%. The City should calibrate large meters (greater than 2") more frequently as a method of reducing unaccounted for water. As mentioned in Chapter 2, the City should also begin monitoring the unmetered fire suppression lines for large users. This strategy should utilize a portable flow meter and can help the City estimate unaccounted for uses or determine which fire suppression lines should be metered. This is further discussed in the improvements section of Chapter 6. Water reuse should continue to be pursued as a viable method of reducing water demands. If the City is able to work with METRO to serve the Fort Dent area with treated wastewater effluent, the City could save an additional 7 million gallons annually. Other potential reuse projects in the E Marginal and W Marginal areas should also continue to be explored for use in the near future. 5-11 CHAPTER 6 RECOMMENDATIONS AND IMPROVEMENTS This chapter of the Water System Comprehensive Plan presents a Six-year Capital Facilities Plan (CFP) in accordance with the requirements of WAC 246-290. Water system capital facility improvements have been scheduled and prioritized on the basis of hydraulic analysis, repair history, system expansion, regulatory requirements, reliability, cost/benefit ratio, and financial priority. For the proposed projects identified in this chapter, individual project descriptions and preliminary project cost estimates have been developed and are presented in the Appendix. Other projects may arise in the future which are not identified as part of the City's 6 -year CFP. Such a project may be deemed necessary for ensuring water quality, preserving emergency water supply, or addressing unforeseen problems with the City's water system. Due to budgetary constraints, the completion of these projects may require that the proposed completion date for projects in the CFP be rescheduled. The City's 1991 Water System Comprehensive Plan identified numerous capital facility improvement projects and made recommendations for other improvements for the City's water system. These projects are therefore discussed in this chapter regarding the current status of each project and whether they were completed as recommended. Recommended projects and system improvements are discussed in this chapter and cost estimates are also presented herein. A financial analysis of these projects is presented in Chapter 7. PRIOR IMPROVEMENT PROJECTS The proposed improvements from the City's 1991 Water System Comprehensive Plan (WSCP) Update are presented in Chapters 5 and 6 of that document. Many of these recommendations were implemented by the City during the past six -years. Some were reprioritized to be included as part of this plan. Others were postponed beyond the current six-year planning horizon. A list of planning, system, and capital improvements from the 1991 WSCP are presented in Table 6-1. RECOMMENDED IMPROVEMENTS System deficiencies have been identified throughout this plan, including low system pressures, storage deficiencies, system management methods, and conservation programs. This section will discuss recommendations made in the City's 1991 WSCP for system improvements and the City's response to these recommendations. Improvements recommended in this plan will then be identified and discussed for each issue. 6-1 TABLE 6-1 1991 WATER SYSTEM PLAN PROPOSED IMPROVEMENTS Recommendation Location/Facilities , Status Implement a Leak Detection Study City Distribution System Complete, January 1996 Replace Seattle's Existing 21" Steel Water Main in North Tukwila E Marginal Way S between S 115th St and the City Limits Complete, 1997 Replace old KCWD 25 Distribution Mains Allentown, Duwamish Quarry, Poverty Hill, Foster Point 70% Complete, 1997 Design and Construct Storage Facilities for Low Pressures North Hill; 2 MG Above- ground Concrete Reservoir Complete, 1992 Design and Construct Booster Pump Station for Low Pressures North Hill; 2, 50 hp Vertical Turbine Pumps Complete, 1992 Design and Construct Storage Facilities West Hill, 8 MG Postponed Develop Operations and Maintenance Manual City Distribution System Complete, 1994 Explore New Water Sources Groundwater Wells in Southcenter Area Postponed Implement Water Quality Monitoring Program City Distribution System Complete, 1997 Develop and Adopt an Emergency Response Plan City Operations Center Complete, 1992 Improve/Replace Undersized Water Mains Various Ongoing Adopt Design Standards and Developer Extension Policies City Distribution System Complete, December 1996 STORAGE The 1991 plan recommended construction of additional storage in the West Hill area of the City. This storage was intended to help reduce demand charges and satisfy state requirements. However, Tukwila can rely on Seattle's transmission and storage facilities to satisfy equalizing and fireflow storage requirements. This can be considered adequate as long as Seattle's system remains reliable. Should this reliability become unavailable in the future, the City will have to perform a storage analysis at that time. The storage analysis performed in Chapter 3 can serve as a basis for performing a storage analysis in the future. Although Seattle has indicated that it will not renew Tukwila's water supply agreement when it expires, the contract will remain effective through 2012. Tukwila is currently considering joining the Cascade Water Alliance to supply its water needs after Seattle's contract expires. Therefore, Tukwila will not be constructing additional storage within the six-year planning horizon. 6-2 The City completed construction of the North Hill reservoir and pump station in 1992 as recommended by the 1991 WSCP. These facilities have allowed the City to create a high pressure zone at the top of North Hill which is served by the high zone pumps. These pumps operate continuously and utilize a variable frequency drive (VFD) to regulate output based on demands. The storage facilities also help maintain pressures in the main 360 pressure zone using the low zone pumps at the reservoir. These pumps only operate during periods of high demand and do not have the advantage of a pump control device to regulate output flow and pressures. TRANSMISSION AND DISTRIBUTION SYSTEM The City's 1991 WSCP included recommendations for replacing old water mains and looping existing mains. Many of these improvements were completed by the City using financing alternatives such as developer extension money and general facility charges. These recommendations are included in a table in the Appendix in the back of this document. Completed projects are noted in the final column of each project. As discussed in Chapter 4, the WaterCAD hydraulic modeling program identified areas with insufficient flows under peak day and fireflow demand conditions. Nodes with insufficient fireflows are listed in Chapter 4, Table 4-4. Although the City has replaced most 2 and 4 -inch pipes in areas formerly operated by Water District 25 and the Creston Water Association, several areas with undersized pipes still remain in the City's water service area. Primarily, these areas are in Campbell Hill (S Ryan Hill), Duwamish Quarry, Poverty Hill, and a small portion of southeast Allentown. Because water lines smaller than 6 inches cannot support combined fireflow and peak day demands, most of the 2 and 4 -inch pipes were not included in the hydraulic model. As indicated in Chapter 4, deficient flows in Table 4-4 are mostly the result of dead end lines. CONSERVATION PROGRAMS The City's conservation efforts are described in detail in Chapter 5 of this plan. The City has fulfilled the minimum data collection requirements of DOH and continues to work in conjunction with the City of Seattle to coordinate conservation efforts. The City has also enacted a majority of the conservation measures recommended by DOH for a medium sized water system, as shown in Chapter 5, Table 5-2. Measures not implemented by the City are addressed herein. 1. Implement Leak Detection Survey: As indicated in Chapter 2 of this report, the City's lost and unaccounted for water has averaged approximately 21% over the past four years. DOH requires water systems with over 20% lost and unaccounted for water to implement a leak detection program and take efforts to reduce this amount. 6-3 The City recently implemented a leak detection survey in November of 1996 which identified significant leaks within the City's distribution system. These leaks were repaired by the City and lost water was reduced by almost 3% between 1996 and 1997. The City will be implementing another leak detection program during 2001 and will make it a policy to initiate leak detection every three to five years in select areas of the distribution system. 2. Fire Line Audits and Large Meter Calibration: Although the City will be pursuing leak detection efforts to reduce lost and unaccounted for water, City staff have indicated that significant unmetered use may be attributable to fire services for industrial and commercial customers, and inaccurate service meters. The City should implement two programs to address this problem; an aggressive meter calibration program and a fire line auditing system for the large system users. A disproportionate amount of water use within the City system is due to commercial and industrial users. As indicated in Chapter 2, the City's ten largest water users are commercial or industrial customers, and they account for over 35% of the City's annual metered demand. Therefore, small inaccuracies in these meters can lead to significant amounts of unaccounted for water. The City should aggressively monitor and annually calibrate the largest meters in an effort to reduce unaccounted for water. Table 2-3 indicates that approximately 260 (13%) of the City's service meters are 2 -inch or larger. Because fire lines are usually unmetered and can often be used for unauthorized water use, the City should also perform audits on the fire suppression lines that service the large users within the City system. This can be done using a clamp -on sonic metering device. These devices are available for approximately $8,500 and have proven to be extremely accurate. They are portable and can be equipped with a data logger which records flow rate and times over extended periods of time. These meters can enable the City to account for unmetered fire flow usage and reduce unaccounted for water through estimation or by metering large fireflow users. ADDITIONAL CAPITAL FACILITY PROJECTS In addition to the above mentioned improvements, this report recommends that the City develop and implement the following improvements to their water system. Low Zone Pump Control Modifications As discussed in Chapter 3, demand metering charges are assessed against Tukwila for excessive 15 -minute flow rates through the supply stations. The 1997 Demand Metering Report for Tukwila indicated that the most significant demand charges were a result of peak purchases through the CRPL 4 line segment. On this segment, Supply Station 13 contributed the most to the City's current demand charge. Supply Station 13 primarily serves the Tukwila Urban Center and the customers in and around the base of the North 6-4 Hill area. The City's demand metering charge could be substantially reduced if 15 - minute peak purchases were likewise reduced. The low zone pumps located at the North Hill Reservoir have historically been used to mitigate peak flows during summer months. Flow control valves on SS13 and SS15 are set to maintain constant flow rates, and available storage at the reservoir is used to mitigate demand fluctuations. The City has recently installed a 3 -inch Cla-Val at the boundary between the upper and lower zone as a means of supplementing flows through the supply stations. This valve is throttled in order to let a small amount of water flow from the high zone to the low zone. This mode of operation has been moderately successful in reducing 15 -minute peak demands, but does not address the use of the low zone pumps. Because there are no controls on these pumps, they operate at full capacity when used to mitigate small demand increases, resulting in an inefficient and expensive method of operation. A variable frequency drive (VFD) may be a more efficient method of utilizing the low zone pumps and available storage to reduce 15 -minute peak demands. A VFD controls the speed of the pump motor and thus regulates the output of the pump. Using a VFD, the low zone pumps can be operated at less than full capacity during non-critical demand times and also used at the necessary capacity to mitigate demand metering charges during peak purchase times. During this mode of operation, the North Hill Reservoir must be filled regularly during non -peak periods so that it will be available for use each day for peak demands. Costs for VFDs for the two.low zone pumps are approximately $50,000. Chlorine Residual Analyzer at North Hill Pump Station Water stored at the North Hill Reservoir comes directly from the Cedar River Pipeline. Currently the City does not measure chlorine residual at the reservoir before it is supplied to customers. The City should install a chlorine analyzer at the discharge side of the high zone booster pumps in order to monitor disinfectant residual at the outlet of the reservoir. This can assist the City in responding to water quality complaints and monitoring Seattle's water quality. Chlorine residual analyzers can be obtained for approximately $5,000 each and are readily available from local representatives. SIX-YEAR CAPITAL FACILITY PLAN A Six -Year Capital Facility Plan (CFP) has been developed which includes the projects discussed in the previous sections. The Six -Year CFP has been developed in conjunction with the Public Works Department and the City's Financing Department using the City's approved 1998-2003 Capital Improvement Program. Table 6-2 lists the projects in the order that is proposed for scheduling. The table includes the project name, purpose, and total estimated cost. Estimated costs for six-year improvement projects have been adjusted for inflation at three percent annually. The locations of the projects included in the Six -Year CFP are shown on the improvement map in Plate 3 at the end of this document. Costs associated with these improvements are discussed in Chapter 7. 6-5 The most significant costs for improvements in the six-year planning horizon are for distribution main improvements. As discussed previously, undersized water mains are still located in many areas of town, including Allentown, Poverty Hill, and Campbell Hill. Phase I of the Allentown neighborhood revitalization was completed in 1997 and included upsizing 2 and 4 -inch water mains to 8 and 10 -inch. Phase II of this project is scheduled for 1999 and will include both similar water and sewer improvements for customers in that area. Upsizing water mains in the Campbell Hill neighborhood is also scheduled in the six-year planning horizon. Poverty Hill improvements have been postponed beyond the twenty-year horizon. The City has also scheduled water main improvements in the urban center for increasing flow capabilities, creating pipe looping, and replacing old cast iron pipes with ductile iron. Improvements here are scheduled along Minkler Boulevard, Andover Parkway, Interurban Avenue, and Southcenter Parkway. The City also plans to create a loop from the Foster neighborhood to Allentown. These projects will all increase available fireflows, and the pipe replacement projects will help bring the City's distribution mains up to their standards. Other improvements in the Six -Year CFP include the recommended leak detection survey, upgrading the telemetry system for 2000 compatibility, and upgrading the pumps with a VFD. Purchase of the chlorine residual analyzer and portable flow meter are both scheduled in 1999 under Instrumentation Upgrades. TWENTY YEAR CAPITAL FACILITY PLAN The Twenty -Year Capital Facility Plan (CFP) was prepared by the Public Works Department and is included in the Appendix. Most of the improvements in this planning horizon were proposed in the City's 1991 Water Supply Comprehensive Plan. Costs for these improvements were also prepared in the 1991 Plan and are included in the Appendix. Improvements scheduled in the twenty-year planning horizon are also included on the Improvement Map in Plate 3 in the Appendix. 6-6 TABLE 6-2 SIX YEAR CAPITAL FACILITY PLAN Priority - No. , 1991 WSCP Plan .. • Improvement No. Project t.. •Description Length Size ,., ?Location , .a Projects Cost ' ,.

Chapter 2 also contains a discussion of the City's wholesale water purchase rates. As shown in Chapter 2, there are currently an estimated 11,401 system ERUs. Based on projected 1998 water sales revenues (provided by the City) each ERU pays a monthly water bill of $20.52 ($20.52 = $2,808,000/12/11,401). FINANCIAL STATUS OF EXISTING WATER UTILITY The City of Tukwila operates a combined water and sewer utility, but tracks water and sewer revenues and expenses separately. Table 7-1 summarizes the City water utility historical revenues and expenses. Water utility revenues and expenses have been significantly impacted by the large 1995 and 1996 capital improvements associated with the East marginal takeover. The revenue bond that financed these improvements is shown as a 1995 revenue and construction costs are shown as 1995 and 1996 expenses. The City projects that at the end of 1998, an estimated reserve balance of $400,000 will be available for capital improvements. Because of recent water rate increases water sales revenues in 1997 were over $400,000 greater than the sum of O&M expenses, purchased water costs, and debt service expenses.

Table 7-3 summarizes current water/sewer debt service. Recent water and sewer improvements were made in the Allentown neighborhood, and these improvements were partially funded from the City's street utility. A sub -account in the City's street utility contains funds that can be used for neighborhood revitalization, and to date, $1,300,000 from this account has been used for utility improvements. Repayment of this interfund loan is discussed later in this Chapter.

The PWTF, established in 1985 by legislative action, offers loans substantially below market rates, payable over periods ranging up to 20 years. Interest rates are 1%, 2%, or 3%, with the lower interest rates providing an incentive for a higher financial share. A minimum of 10% of project costs must be provided by the local community to qualify for a 3% loan. A 20% local share qualifies the applicant for a 2% interest rate and a 30% local share qualifies for a 1% loan. The useful life of the project determines the loan term, with a maximum term of 20 years. To be eligible, an applicant must be a local government such a City, Town, or County, to special purpose utility district, and have a long-term plan for financing its public work needs. If the applicant is a Town, City, or County, it must adopt the 1/4% real estate excise tax dedicated to capital purposes. Eligible public works systems include streets and roads, bridges, storm sewers, sanitary sewers, and domestic water. Loans are presently offered only for purposes of repair, replacement, rehabilitation, reconstruction or improvement of existing service users. Ineligible expenses include public works financing costs that arise from forecasted, speculative, or service area growth. Such costs do not make a project ineligible but must be excluded from the scope of their PWTF proposal. The funding program operates on an annual cycle, with April and August application dates. The August application date is for preconstruction only, and preconstruction money is typically available by the end of the year. The April application date is for both 7-3 preconstruction and construction loans, with money available in May of the following. year. Drinking Water State Revolving Fund Loans of up to $1,000,000 are available from this program, which involves the administration of federal funds by two state agencies. Applications for this program are due on July 1st of each year with money being awarded to successful applicants around the beginning of the next year. Terms of the loan vary according to the market interest rate and financial hardship considerations. Currently, a 4.3% interest rate over a 20 -year repayment period is offered. Lower interest rates and longer repayment periods are available in cases of financial hardship. Community Economic Revitalization Board (CERB) This low interest loan and grant program is sponsored the Department of Trade and Economic Development. Funding is available for infrastructure that supports projects which will result in specific private developments or expansions n manufacturing and businesses that support the trading of goods and services outside the state's border. Funding is not available to support retail shopping developments or acquisition of real property. The projects must create or retain jobs. The average is one job per $3,000 of CERB financing. Interest rate fluctuates with the state bond rate. Community Development Block Grant (CDBG) CDBG funding is available through King County. A maximum of $500,000 in grant funding is available, and water utility improvements are eligible projects. The project must principally benefit at least 51% low- to moderate -income households, defined in 1997, for a family of four, as an income less than $27,550 (low income) and $43,500 (moderate income). Applications for the annual funding cycle are typically due in June of each year. Revenue Bonds The most common source of funds for construction of major utility improvements is the sale of revenue bonds. The tax-free bonds are issued by the City. The major source of funds for debt service on these revenue bonds is from water service rates. In order to qualify to sell revenue bonds, the City must show that its net water utility operating income (gross income less expenses) is equal to or greater than a factor, typically 1.2 - 1.4, times the annual debt service on all par debt issued. This 1.4 factor is commonly referred to as the debt coverage factor and is applicable to revenue bonds sold on the commercial market. The required debt coverage factor may be specified in previous revenue bond ordinances. If not, it will be determined at the time of bond issue. General Obligation Bonds The City, by special election, may issue general obligation bonds to finance almost any project of general benefit to the City. The bonds are paid off be assessments levied against all privately -owned properties within the City. This includes vacant property which otherwise would not contribute to the cost of such general improvements. This 7-4 type of bond issue is usually reserved for municipal improvements that are of general benefit, to the public, such as arterial streets, bridges, lighting, municipal buildings, firefighting equipment, parks, and water and wastewater facilities. General obligation bonds have the best market value and carry the lowest rate of interest of all types of bonds available to the City. Disadvantages of general obligation bonds include the following: Voter approval is required which may be time-consuming, with no guarantee of successful approval of the bond. The City may have a practical or legal limit for the totalamount of general obligation debt. Financing large capital improvements through general obligation debt reduces the ability of the utility to issue future debt. Utility Local Improvement Districts Another potential source of funds for improvements comes through the formation of Utility Local Improvement Districts (ULIDs) involving an assessment made against properties benefited by the improvements. ULID bonds are further guaranteed by the revenues and are financed by issuance of revenue bonds. ULID financing is frequently applied to water system extensions into areas previously not served. Typically, ULIDs are formed by the City at the written request (by petition) of the property owner within a specific area of the City. Upon receipt of a sufficient number of signatures on petitions, the local improvement area is defined. Each separate property in the ULID is assessed in accordance with the special benefits the property receives from the water system improvements. A City-wide ULID could form part of a financing package for large-scale capital projects such as water supply or storage improvements which benefit all residents in the service area. The City-wide ULID would be formed by a majority vote of the City Council. There are several benefits to the City in selecting ULID financing. The assessment places a lien on the property and must be paid in full upon sale of the property. Further, property owners may pay the assessment immediately upon receipt reducing the costs financed by the ULID. The advantages of ULID financing, as opposed to rate financing, to the property owner include: 1. The ability to avoid interest costs by early payment of assessments. 2. Low-income senior citizens may be able to defer assessment payments until the property is sold. 3. Some Community Development Block Grant funds are available to property owners with incomes near or below the poverty level. Funds are available only to reduce assessments. 7-5 The major disadvantage to the City-wide ULID process is that it may be politically difficult to approve formation. The ULID process may be stopped if owners of 40 percent of the property are within the ULID boundary protest its formation. Developer Financing Developers may fund the construction of extensions to the water system to property within new plats. The Developer extensions are turned over to the City for operation and maintenance when completed. It may be necessary, in some cases, to require the developer to construct more facilities that those required by the development in order to provide either extensions beyond the plat and/or larger pipelines for the ultimate development of the sewer system. The City may, by policy, reimburse the Developer through either direct outlay, latecomer charges, or reimbursement agreements for the additional cost of facilities, including increased size of pipelines over those required to serve the property under development. Compensation for oversizing is usually considered when it is necessary to construct a pipe larger than eight inches in diameter in residential area to comply with the intent of the Comprehensive Plan. Construction of any pipe in commercial or industrial areas that is larger than the size required to service the development should also be considered as an oversized line possibly eligible for compensation. Developer reimbursement (latecomer) agreements provide up to 10 years or more for developers to receive payment form other connections made to the developer -financed improvements. System Development Charges The City may adopt a system development charge to finance improvements of general benefit to the total water system which are required to meet future growth. System development charges are generally established as one-time charges assessed against new water customers as a way to recover a part of the cost of additional system capacity constructed for their use. The system development charge or fee is deposited in a construction fund to construct such facilities. The intent is that all new system customers will pay an equitable share of the cost of the system improvements needed to accommodate growth. Typical items of construction financed by the system development charge are water treatment facilities, pump stations, transmission lines, and other general improvements that benefit the entire system. OPERATION AND MAINTENANCE EXPENSE PROJECTIONS Operation and maintenance expense projections were supplied by City staff and they are summarized in Table 7-4. These projections are based on the 1997 actual water utility expenses and have been prepared in conjunction with the Public Works Operations department and include $10,000 for Cascade Water Alliance membership fees in 1998. 7-6 TABLE 7-4 PROJECTED OPERATION AND MAINTENANCE EXPENSES Operation and Maintenance Expenses 1998 1999 2000•: 2001 2002 2003 Personnel (Wages, Salaries, & Benefits) $376,300 $387,589 $399,217 $411,193 $423,529 $436,235 Supplies $59,250 $61,028 $62,858 $64,744 $66,686 $70,748 Administrative Expenses $316,000 $325,480 $335,244 $345,302 $355,661 $366,331 Taxes $139,437 $143,620 $147,929 $152,367 $156,938 $161,646 Other Services and Charges $141,755 $131,588 $135,534 $139,602 $143,789 $148,103 TOTAL $1,032,742 $1,049,305 $1,080,782 $1,113,208 $1,146,603 $1,183,063 PURCHASED WATER COST PROJECTIONS Anticipated changes in purchased water costs were received from Seattle Water Department staff. Changes in the peak water charges and new water charge were identified through 2000. Anticipated water rates after 2000 were not provided and are assumed to remain consistent after 2000.

In all, nineteen projects are scheduled in the six-year planning period, at a total cost of $2,925,000, in inflation adjusted dollars. The City intends on financing all of these projects on a pay-as-you-go basis. PROJECTED RATE IMPACTS Table 7-6 summarizes projected water utility rate impacts through 2003. Water rates in 2003 would be $1.05 per month per ERU higher than current rates, as a result of a 5% rate increase in 2000. This rate increase would cover expected inflationary increases in O&M expenses, projected increases in purchased water costs, finance capital improvements totaling $2,925,000 (inflation adjusted dollars), and repay the $1,300,000 interfund loan. Of significant note in this financial plan is that revenue is not collected to cover system depreciation. This could impact the long-term financial position of the utility as existing facilities age. In 1998, system depreciation will total $374,806. Collecting revenue to cover depreciation is one method of accumulating capital reserves so that future system replacement projects can be financed on a cash basis. Cash financing would lessen the City's reliance on future issuances of debt, and by avoiding interest payments, reduce long-term rate impacts to customers. Covering $374,806 in depreciation expense would require an additional $2.66 per month per ERU rate increase above what is shown in Table 7-6. TABLE 7-6 PROJECTED RATE IMPACT SUMMARY Proposed Rate Increases • Current 1998 Water Bill, $/month/ERU $20.52 • Proposed 2000 Rate Increase (5%) $1.05 • Projected 2003 Water Bill, $/month/ERU $21.57 Significant Changes in Water Utility Revenues and Expenses Resulting in Necessity of Water Rate Increases: • Purchase water costs projected to increase by $150,000 per year by 2003 • Repayment of $1,300,000 interfund loan • System improvements totaling $2,925,000 (inflation adjusted dollars) financed without issuance of additional long term debt Significant Utility Expense Not Incorporated Into Financial Plan: • System depreciation. 1998 depreciation of capital facilities equals $374,804 • Any unanticipated changes in purchase water costs above those shown in Table 7-5 7-8 This analysis uses projected wholesale water rates obtained from the City of Seattle. If rate increases beyond those shown in Table 7-5 occur, rate impacts to the City of Tukwila will increase. Table 7-7 summarizes projected water utility revenues and expenses through 2003 in more detail. The first section of Table 7-7 shows projected water utility revenues, including water sales, connection charges, and miscellaneous revenues. Water sales revenues with the existing rate structure are shown, as are water sales revenues from proposed rate increases within the next six years. Water sales revenues, connection fee revenues, and miscellaneous fees were provided by the City. As a result of revised agreements with the City's bond underwriters, the water utility will receive a $495,000 transfer from bond reserves that are no longer required to be maintained. The second section of Table 7-7 shows projected water utility expenses, including operation and maintenance, purchased water, existing debt service, repayment of the interfund loan, and proposed capital projects. The third section shows projected rate impacts. A 5% rate increase is proposed for January 2000, which would result in a $1.05/month/ERU rate impact. Water rates in 2003 will be $1.05/month/ERU higher than current rates. This financial analysis presents the rate impacts in terms of cost per ERU, but does not specify how to distribute these costs among system users. The City can distribute these costs over time and among system users in the manner it chooses. Table 7-7 can be used as a basis for these decisions. 7-9 TABLE 7-7 PROJECTED WATER UTILITY REVENUES AND EXPENSES Water Utility Revenues 1998 1999 - 2000 2001 2002 2003 Water Sales (Existing Rates) [1] [2] $2,808,000 $3,300,000 $3,300,000 $3,300,000 $3,300,000 $3,300,000 Water Sales (Rate Increase) $143,800 $143,800 $143,800 $143,800 Connection Fees $14,000 $20,000 $20,000 $20,000 $20,000 $20,000 Miscellaneous $150,000 $160,000 $170,000 $180,000 $190,000 $200,000 Bond Reserve Transfer $0 $0 $0 $495,000 $0 $0 TOTAL REVENUES $2,972,000 $3,480,000 $3,633,800 $4,138,800 $3,653,800 $3,663,800 Water Utility Expenses ; : ; 1998.. 1999: ; 2000 "" ... 2001- •..:2002 .. 2003 Operation and Maintenance $1,032,742 $1,049,305 $1,080,782 $1,113,208 $1,146,603 $1,183,063 Purchased Water [1] • $792,720 $962,920 $1,106,720 $1,106,720 $1,106,720 $1,106,720 Debt service $764,000 $716,000 $719,000 $719,000 $697,000 $694,000 Repayment of Interfund Loan $0 $350,000 $300,000 $300,000 $100,000 $250,000 Capital Projects $29,000 $672,000 $785,000 $293,000 $743,000 $403,000 TOTAL EXPENSES $2,618,462 $3,750,225 $3,991,502 $3,531,928 $3,793,323 $3,636,783 Reserves andfRate:Impacts, -1998 1999 r °` . 2000 -2001', 4;-:. ` X2002 2003.

The City owns and operates a system for the supply, transmission and distribution of water and is authorized to sell and distribute water to its own inhab- itants and also to other persons and customers outside the corporate limits of the City. 2. The City has met the water needs of its pur- veyors outside its corporate limits in the past with- out written Long-term Contracts, and will make provision in its long-range plans for the continuing requirements of such service in the future for those purveyors sign- ing Long-term Contracts, who have foregone and will fore- go long-range capital expenditures for supply and 1 wholesale distribution in reliance thereon in accordance with this Contract and except as otherwise provided for herein. 3. In the past, the City has supplied water to purveyors for resale pursuant to a general wholesale rate schedule established by the City, and it is now the purpose of both parties to establish by agreement cer- tain rights and duties incident to future water service and supply. 4. It is contemplated that the City will enter ti into contracts similar to those designated Versions A or B dated November 1981 with other purveyors who agree to enter into Long-term Contracts. 5. The City is willing to continue to serve as a regional water supplier if this role does not place financial burdens on the Direct Service.ratepayers of the City from which they would not receive a corres- ponding benefit. 6. It is the intent of both parties that this Contract will not preclude one or more purveyors from financing and/or constructing certain new water supply facilities for use or partial use by purveyors, with the understanding that the City would have to approve, by separate agreement, the financing and/or construction by such purveyor or purveyors of any such facility that the City would otherwise be required to provide in order to comply with the provisions of this Contract. NOW, THEREFORE, in consideration of mutual covenants herein, it is agreed as follows: 2 SECTION I. TERM OF CONTRACT AND GUARANTEES I.A. Term of Contract 1. Subject to the other provisions contained herein, the original term of this Contract shall commence and this Contract shall become effective on the date of the City's execution hereof. This term shall continue and this Contract shall remain effective until January 1, 2012. 2. Subsequently, the contract term shall be extended for additional fifteen (15) year incre- ments, provided both parties express their intent to do so in writing at least fifteen (15) years prior to the end of the contract term or extension thereof. I.B. Agreement to Supply and Purchase Water 1. The City agrees to supply the water require- ments of the Purveyor subject to conditions of this Contract. The Purveyor shall purchase water from the City as specified in Exhibit I -B except for the quantity of water presently obtained by the Purveyor from other sources or committed to be obtained from other sources, provided that documen- tation of such quantities and copies of such com- mitments have been transmitted to the City (along with this Contract) prior to the City's execution of this Contract. 2. In the event the Purveyor should annex to or transfer all or a portion of its service area 3. Version B Corrected 2-3-82 receiving City water, adjustments s 11 be made in the Purveyor's water requirements to reflect that associated with these areas. 3. Should the entire water service area of the Purveyor be annexed to the City, then this Contract shall become null and void at the time of the annexation, and the City shall become responsible for that portion of the Purveyor's costs as set forth in Paragraph I.B.4.b. of this Section. 4. Also, the Purveyor may reduce the amount of water it has contracted for in Exhibit I -B under the following conditions, except that said con- ditions do not apply in the case of partial annexa- tion by the City: a. Atleast five (5) years' written notice of the reduction is provided to the City and the Purveyor Committee. b. The Purveyor holds the City and other pur- veyors signing Long-term Contracts on the dEtd-° 5. The Purveyor may also obtain water from other State -approved sources upon the prior written con- sent of the City, in those instances where: a. The City determines that the City's major supply facilities are not adequate to supply the Purveyor the amount of water specified in Exhibit I -B. b. The Purveyor interconnects with other purveyors' systems or the Purveyor devel- ops other sources for summer water supply peaking purposes when said interconnection or development is for the purpose of avoid- ing a demand charge. 6. The Purveyor shall not enter into any new agreements for water supply with any other entity to either purchase or wholesale water without first having obtained the written consent of the City, which consent will not be unreasonably withheld. I.C. Assignability 1. This Contract shall be binding upon all suc- cessors and assigns of the parties. Neither party may assign or transfer its interest in this Contract without the written consent of the other party, which shall not be unreasonably denied, except that such consent shall not be required when the assignment or transfer is mandated by State law. Subject to such limitation, the City and/or the Purveyor may assign its interest to a legally constituted regional water authority. 5 or receive allY of the „ 1,..

Except in cases of emergency, and in order that the Purveyor's operations will not be unreasonably the Purveyor interruption interfered with, the City shall give reasonable written notice of any such or reduction, the reason therefor, and the probable duration thereof. 4. If such interruption or reduction in service should occur, thus necessitating the Purveyor to draw supplies during peak demand times that might thus subject the Purveyor to demand charges, such charges shall not be applied to the Purveyor. Water Quality 1. The quality of water delivered under this Contract shall comply with all applicable provi- sions of the State and Federal law and rules and regulations of the appropriate State and Federal agencies governing water quality; and shall be sub- ject also to applicable provisions of City ordinan- ces relating thereto and not inconsistent herewith. 2. Both parties agree that this provision will not be binding on the City in instances in which an emergency exists and best efforts and reasonable prudence have been exercised. 7 SECTION II. CONDITIONS OF SERVICE II.A. Minimum Hydraulic Gradient 1. A minimum hydraulic gradient or head for each Service Connection shall be used as a criterion for the City's and Purveyor's comprehensive water plan- ning efforts. If the City finds that it would bene- fit the Regional Water Supply System and purveyors as a class, the minimum hydraulic gradient or head in Exhibit II -A may be modified by the City only once during any fifteen (15) year period after,, re- view by the Purveyor Committee, provided that four (4) years' advance notice is given to the Purveyor. 2. The City will use its best efforts to supply water from its system to that of the Purveyor at the points of connection and at not less than the minimum hydraulic gradient or head at the inlet side of the Service Connection meter as shown on Exhibit II -A, except as noted in this Contract. It is understood that circumstances may prevent the City from providing, at all times, this minimum hydraulic gradient. In such cases, the City shall supply a volume of water equivalent to and deli- vered at the maximum 24-hour average flow rate, required by the Purveyor in accordance with Sections I.B. and V.A., for 24 hours. 3. Additional Service Connections between the Purveyor's and the City's water systems or adjusted, minimum gradients may be established from time to time, by mutual agreement between the City and the 8 Purveyor, in which instance Exhibit II -A shall be appropriately amended to reflect such additional 9 other systems without the written (or oral, in case of emergency) approval of the City, which approval shall not be unreasonably witheld. Said other systems must be in compliance with all applicable County, State and Federal laws and regu- lations, and must have been approved by the State. (Also see Section I.B. & II.B.) II.E. Metering Equipment The City shall own'and maintain appropriate metering devices to measure the water flowing from the City's Regional Water Supply System to the A- ter system of the Purveyor at each Service Connec- tion. The City agrees that at the Purveyor's re- quest it will install and maintain equipment se- lected by the Purveyor and approved by the City to transmit signals to the Purveyor's recording equip- ment (located elsewhere) of the amount of water de livered as measured by the City's meters, all at the Purveyor's expense. 10 SECTION III. COST OF WATER III A. Rate-making Principles and Policies 1. Existing rates shall apply until adjusted in accordance with Section III.E. 2. Future rates will be based on the following fundamental principles: a. The City, in setting water rates, will treat the purveyors as a separate customer class from the customers to whom it pro- vides Direct Service through its own distribution system. b. All costs of serving the purveyors as a class will be recovered by water rates charged to the purveyors. c. The cost of serving purveyors as a class will be determined by a rate study which allocates shares of costs to purveyors in accordance with accepted practices for cost allocation. • 3. The following general policies are also intended to give guidance to rate-making studies and associated documentation performed during this Contract. These policies may unavoidably conflict in their applicability; however, these policies shall be considered in their entirety in an attempt to strike an overall balance among them and shall be followed to the extent feasible in setting rates. 11 III.B. 1. The purveyors' portion of the City water utility's total revenue requirement will consist of allocated shares of maintenance and operation 12 a. No expenses that would normally be allo- cated to power development shall be allo- cated to the purveyor class unless the purveyor class is allocated a commen- surate share of revenue derived from such a development. b. Abrupt changes in financial policies SElir should be minimized. c. The rate structure should: 6a porNATu ° 1) Discourage wasteful use /Of utility resources. 2) Be innovative whenever it is cost- effective and when it is beneficial in furthering the rate -making poli- cies. 3) Be simple and understandable. 4) Be fair and equitable. d. If, as a result of supplying water to any new purveyor customer, the City in- curs capital costs which benefit only the new purveyor customer and which do not benefit the purveyors as a class then or in the future, such costs shall not be allocated to other purveyors who sign a Long-term Contract. Net Revenue Requirements expenses, personnel taxes and other allowable taxes, and capital costs. In establishing rates, the City water utility's most current accounting information together with other fiscal information will be utilized as a foundation to project costs. 2. For rate -making purposes, the individual maintenance and operation expenses will be aggregated in a manner similar to that used by the City in establishing water rates since 1968 as reflected in the 1970, 1974, and 1980 rate study reports of the City along with all supporting data and methodology. For determining capital costs, the City will maintain in its accounting records an aggregation of the original cost of each facility serving the purveyors, the value of all contribu- tions, net additions and deletions and other per- tinent data. 3. The total expenses from the sources iden- tified above shall be allocated to purveyors in a manner generally consistent with the methodologies utilized in previous rate studies. Watershed management and timber management expenses will be clearly delineated and their equitable distribution to purveyors will be demonstrated in each rate study. For all allocation calculations involving significant sums of money, numbers will be carried out to three decimal places. 4. All capital costs except those associated with New Expansion Facilities will be determined 13 using the utility basis of rate -making where: a. Contributed capital and depreciation on contributed capital are excluded from capital cost calculations, leaving net original cost. b. The rate base is defined as the allo- cated net original cost of all capital assets and projected additions during the rate period, less retirements during the rate period, less accumulated depre- ciation, plus a working capital allowance. c. The rate of return to be applied to the rate base is derived from a weighted sum of the average cost of debt to the City's water utility duringthe rate period and the cost of equity capital. The cost of equity capital is the return on alternative investment opportunities available to the City's customers. The weights used above will be the ratios of debt-financed and revenue -financed capi- talization to the City water utility's non -contributed pla indicators, such as of other utilities of borrowed funds, nt. Other relevant comparative earnings and the current cost may also be examined to support or modify the rate of return suggested by the weighted cost of capi- tal. 14 d. The annual depreciation expense will be calculated by multiplying a depreciation rate reflecting the City's standard use- ful life for each allocated asset times the net original cost of the asset. 5. The capital cost to be recovered from the purveyors for New Expansion Facilities serving them will be determined on the cash basis, consisting of debt service and capital expenditures financed with revenues. 6. New Expansion Facilities costs will be allo- cated between purveyors and Direct Service custo- mers on the basis of their ultimate shares of the design capacities of these facilities. The alloca- tion of the costs of such facilities will be based on the projections made or reviewed by an indepen- dent consultant at the time of each rate study. 7. The purveyors' portion of the total revenue requirement, less projected net receipts from purveyor meter charges, demand charges, other charges and any emergency surcharges, and adjusted for the balance in the Purveyor Balance Account, will be termed Net Revenue Requirements. III.C. Purveyor Rate Structure 1. Net Revenue Requirements will be recovered from purveyors through a commodity rate and/or rate schedule. This commodity rate and/or rate schedule may vary with consumption, peak demand, or other 15 variables to reflect differences in the City's cost of service associated with these variables. 2. In order to distribute the costs of Regional Water Supply System expansion equitably, the com- modity rate and/orrate schedule may vary to re- flect the differences in the costs of providing for "old" and "new" consumption. Old consumption will will be defined as the average amount of City wa- ter consumed by each purveyor in a base period which shall be the 3 -year period from January 1, 1979 to December 31, 1981. New consumption will be defined as each purveyor's actual consumption of City wa- ter less its average old consumption for a corres- ponding period of time. 3. In particular, annual new consumption will be defined as each purveyor's actual annual con- sumption of City water less average annual old con- sumption. The aggregate amount of old and new con- sumption billed during a year will be adjusted, if necessary, to equal the total annual old and new consumption as defined above. 4. If the Purveyor should annex or transfer service areas previously receiving City water, adjustments will be made in the Purveyor's old consumption to reflect that associated with these areas. S. The City may establish an old consumption rate, and a growth charge, which combined with the old consumption rate, is defined as the new con - 16 sumption rate. The intent of the old consumption rate is to recover the costs of existing facili- ties, and replacements and improvements to these facilities, from total consumption. The intent of the growth charge is to allocate the costs of New Expansion Facilities to new consumption. Use of old consumption/new consumption rates for pur- veyors in no way affects the total revenue to be paid by the purveyor class. 6. If no new consumption is projected, total purveyor Net Revenue Requirements (old and new) will be recovered through a commodity rate and/or rate schedule based on total purveyor consumption. If there are no New Expansion Facilities costs, all consumption (old and new) will be charged at the old consumption rate. 7. The Purveyor may, by signing Exhibit III -C, opt to average its commodity billing with those of other purveyors who sign a substantially similar version of this Contract and also exercise the option set forth in Exhibit III -C. This option may only be exercised WITHIN 90 DAYS OF THE APPROVAL OF r THE FIRST RATE ADJUSTMENT BUT. IN NO EVENT, LATER THAN 04 10 DAYS.PRIOR TO IMPLEMENTATION OF THIS RATE ADJUSTMENT. III D. Provision for Emergency Surcharge 1. In the event of a severe drought, major catastrophe, or other extraordinary conditions that require emergency expenditures to maintain a suf- ficient water supply, it may be necessary for the City toimpose, by Ordinance, an emergency surcharge 17 on purveyors in order to pay for such expenditures. An equitable portion of these costs will be allo- cated to purveyors in accordance with the prin- ciples set forth in Section III.A. and may be recovered through an emergency surcharge. 2. An emergency surcharge based on water usage may be implemented immediately upon passage of the authorizing Ordinance and apply to all regular billings thereafter transmitted and may continue as long as necessary to pay for emergency expenditures, which shall be accounted for by the City to the Purveyor. III.E. Rate Adjustment Procedure 1. The City may adjust rates to purveyors upon one hundred eighty (180) days notice of intent to do so. Rate adjustments will be effected only af- ter completion of a cost -of -service study including an allocation of operation, maintenance and capital costs between purveyors and Direct Service custom- ers of the City. Such a study will be performed or thoroughly reviewed by an independent rate consul- tant. Nothing herein shall preclude phased imple- mentation of a rate adjustment resulting from a sin- gle rate study, provided that the period between completion of the rate study and the effective date of any rate adjustment based upon that study shall not exceed five (5) years. 2. The independent rate consultant will be selected by the City. Recommendations from the 18 Purveyor Committee will be Y considered in making ' this selection. Detailed information and progress reports will be made by the City to the Purveyor and Purveyor Committee during the course of the ' study upon drafting of each major study section directly affecting the purveyors. Additionally, the City shall provide substantially completed purveyor -related sections of the study and, if requested, copies of the underlying computations to the Purveyor and the Purveyor Committee not less than thirty (30) days before formally transmitting ' any resulting rate adjustment proposal to the City Council. Any comments, analyses, reports, or recommendations by the Purveyor Committee con- cerning the rate study will be formally transmitted 2. If the City conveys all or part of its Regional Water Supply System to another water supply authority (hereafter called the purchaser) with the legal authority to take over and operate a part or all of the City's Regional Water Supply System, then the City shall also convey PFA facili- ties that are an integral part of the water system conveyed. Compensation to the City by the purchaser for these facilities shall be the conveyance value of such facilities determined at the time of trans- fer less the contract-signing purveyors' share of this conveyance value. The contract-signing pur veyors' share shall be the percentage of the facil- ities' costs that have been allocated to and paid by the contract-signing purveyors since signing the contract. 3. If PFA facilities are conveyed to an agency that does not serve all of the purveyors that have signed Long-term Contracts and subsequently contri- buted to the payment of such facilities, then these purveyors shall be compensated by the purchaser according to their pro-rated share of the contract- signing purveyors' share of the conveyance value of such facilities. The compensation to these pur- veyors shall be made in a manner similar to that used to compensate the City. 4. It is understood that nothing herein shall obligate the City to compensate the purveyors directly for the conveyance of PFA facilities. 20 5. It is understood that the City retains full ownership of these PFA facilities until such time as they are conveyed. III.G. Direct Service Rate -setting Each party to this Contract shall have sole authority for establishing Direct Service rates within their respective jurisdictions. III.H. Demand Charge 1. A demand charge will be made in accordance with the methodology described in Exhibit III-H.:The demand charge rate (i.e., dollars per 1000 gallons of deficient storage) shall be based on the equiv- alent cost of providing the deficient storage. This rate will be determined as part of each rate study. 2. The proceeds of the demand charge will be treated in rate setting as a credit to the purveyor revenue requirements for new consumption. III.I. Purveyor Balance Account and Annual Report 1. The City will maintain accounting records in accordance with the State Auditor's prevailing requirements. Annually, by August 31st, the City will provide to the Purveyor an accounting state- ment of the actual costs incurred to serve pur- veyors and the revenue derived from them, and a report of the status of the Purveyor Facilities Account. In determining the amount of revenue to be recovered from purveyors by subsequent rates, any balance of past purveyors' revenues over costs will be credited against gross revenue requirements or 21 any shortage due to failure to recover past costs from purveyors will be added to gross revenue requirements of purveyors. 2. Interest will be earned by purveyors on any accumulated balance or charged to purveyors on any shortage. Such interest will be simple interest, computed annually at the rate of return on equity established at the time of relevant rate form- ulation. The interest due or owed by the pur- veyors will be credited against or added to the gross revenue requirements determined in the sub- sequent rate study. III.J. Cost of New or Changed Service Connection The entire cost of each additional Service Connection, including the cost of meters, shall be paid by the Purveyor. If the City removes and replaces a Purveyor meter because it is under or over capacity (based on AWWA standards or factory rating criteria), or where the Purveyor desires to change, interrupt or discontinue a service con- nection, then the net cost of these changes shall be paid to the City by the Purveyor. 22 SECTION IV. REPRESENTATION - PURVEYOR COMMITTEE IV.A. Seattle Water Purveyor Committee 1. In order that purveyors may, in an orderly way, be involved in the operation, expansion and financing of the City's Regional Water Supply System, there shall be established the Seattle Water Purveyor Committee, herein called the "Purveyor Committee". Each purveyor signing a Long-term Contract shall 'select a representative (with an alternate) on the Purveyor Committee. 2. The Purveyor Committee shall organize itse/f and become operational no later than July 1, 1982 and adopt such rules as are necessary for its operation. The number of votes for each pur- veyor shall equal its percent of total annual amount of water supplied to purveyors by the City during the preceding year (rounded to the nearest whole percent) provided that each purveyor shall have at least one (1) vote. 3. The Purveyor Committee shall have no authority to financially encumber contracting purveyors as a result of this Contract. 4. No activity by the Purveyor or the purveyors in conjunction with the Purveyor Committee shall affect the City's obligation to supply water to the Purveyor under this Contract. 23 SECTION V. PLANNING V.A. Reporting of Planning Data 1. The Purveyor agrees to report to the City: a. Its annual and peak day total system de- mand for each year during the term here- of as December 31st of that year. b. Its. forecast of water requirements to be supplied by the City including estimates of annual and maximum 24-hour require- ments for the ensuing calendar year, for the fifth, tenth, and fifteenth year ''in the future. Such forecasts shall re- flect the best judgment of the Purveyor. Such information shall be furnished to the City no later than the following April 1st of each year. 2. The Purveyor also agrees to report certain other data relating to water supply as may be requested by the City for water planning purposes, provided that supplying such data shall be reason- ably within the means of the Purveyor. 3. Records relevant to water supply and con- sumEition within the possession of the City or the Purveyor will be provided to the other upon reason- able request. V.B. Submittal of Purveyor Comprehensive Plans The Purveyor shall provide its water comprehensive plan and significant amendments thereto to the City for inclusion by the City in the City's Comprehensive Regional Water Plan. 24 V.C. Conservation Program 1. The City's regional water conservation ' program, as contained in its Comprehensive Regional Water Plan, is to be updated by the City and, sub- sequent to review by the Purveyor Committee, adopted by the City. This program shall be imple- mented by the City with the assistance and support the City's regional water conservation program. It is understood that the Purveyor retains final authority over the expenditure of funds needed to implement its program for its own service area. V.D. City as Water Planning Agency The City, as the lead agency, is herein considered the planning authority for the water supply requirements of this Contract. The City shall examine and investigate ,water supplies suitable and adequate for present and reasonable future needs thereof. The City shall prepare and adopt a plan for acquiring such water supplies in a 25 timely fashion. This plan shall include provision for the lands, waters and water rights and ease- ments necessary therefor, and facilities for retaining and storing and delivering any such waters, including dams, reservoirs, aqueducts and pipelines to convey same throughout the system. In preparing or adopting its plan, the City shall con- sider as possible alternative or additional water supply sources the acquisition of water from sour- ces controlled and/or developed by individual pur- veyors, legally -constituted groups of purveyors, and other utilities which are not presently supplied by the Regional Water Supply System. V.E. Comprehensive Regional Water Plan The City before ordering any major improve- ments to fulfill the requirements of this Contract shall adopt and maintain a comprehensive plan for its Regional Water Supply System; when said plan is updated or amended, it shall be reviewed by the Purveyor Committee prior to submission to the City council. This plan shall include facilities, for contract -signing purveyors, that are based on reasonable criteria, including, but not limited to, cost-effectiveness and environmental impact. The Committee shall .respond within ninety (90) days of receipt of same or its approval is assumed to be given. The response submitted by the Committee regarding facilities substantially affecting pur- veyors will be seriously considered by the City. 26 A serious endeavor by the parties will be made to arrive at a mutually acceptable plan. Response by the City will be provided to the Committee within ninety (90) days. The Committee will be involved in developing the City's Comprehensive Regional Water Plan. However, the City has final deter- mination responsibility forthe plan and its abi- lity to fulfill the conditions of this Contract and other City contracts and commitments. V.F. Emergency Planning An emergency plan shall be prepared and maintained by the City as part of its Comprehensive Regional Water Plan to provide for water supply in the event of drought or disaster. Such plans shall be prepared pursuant to the •procedure outlined in Section V.E. 27 SECTION VI. PAYMENT VI.A. Collection of Money Due City Each purveyor shall be billed by the City on a monthly basis for the supply of water delivered by the City. The Purveyor shall pay these water bills within sixty (60) days of the billing dates. Penalties for Late Payment The City may assess a late charge on any pur- VI .B. veyor for failure to make full and timely payment as provided in Section VI.A. This late charge shall be established by the City as a percentage of the late portion of the water charges owed, pro- vided that the percentage rate shall not exceed maximum amount permissible by law. VI.C. Disputes The Purveyor may dispute the accuracy of any portion of the water charges by taking the following two actions within the sixty (60) day payment period established in Section VI.A: (1) notifying the City in writing of the specific nature of the dispute, and (2) paying the undisputed portion of the water charges. The City shall consider and decide any billing dispute in a reasonable and timely manner. Late charges will start to accrue on any unpaid disputed water charges only after the City has rendered a final decision and after expiration of any additional "grace period" which may be established by the City as part of the final decision on the dispute. the 28 SECTION VII. AMENDMENTS TO PURVEYOR CONTRACT VII.A. Procedure for Amending the Contract 1. Either party may request in writing the oth- er to consider an amendment of this Contract. If the amendment is mutually acceptable to the City and the Purveyor, an amendment of this Contract shall be prepared in writing and become effective upon execution by both parties, provided that at least ninety (90) days prior notice has been given to the Purveyor Committee. 2. All the purveyors who have signed Long-term Contracts will be notified by the City of contract amendments thereof and will have the option of including same in their contract if they elect to do so within two (2) years of the date that notifi- cation is sent. This provision does not apply to amendments of Exhibits I -B and II -A which will be unique to each purveyor. VII.B. Subsequent Contracts The City, without having given ninety (90) days prior notice of its intent to so execute to the Purveyor and the Purveyor Committee, shall not execute Long-term Contracts for water supply with any purveyor after July 1, 1982 if that contract contains provisions inconsistent with or in addi- tion to those contained in Contracts designated Version A and B dated November 1981. In the event that the City does execute any such contract, such provisions will be incorporated in this Contract 29 if the Purveyor elects to do so within two (2) years of the date notification was sent. This pro- vision does not apply to Exhibits I -B and II -A which will be unique to each purveyor. SECTION VIII. OTHER PROVISIONS VIII.A. Notification 1. Whenever in this Contract, notice is re- quired to be given, the same shall be given by the following representatives by United States mail (registered or certified with return receipt requested,) addressed to the respective parties at the following addresses: CITY: PURVEYOR: Superintendent of Water Public Works Director Seattle Water Department CITY OF TUKWILA Exchange Building, llth Floor 6200 Southcenter Blvd. 821 Second Avenue Tukwila, Washington 98188 Seattle, WA 98104 unless a different representative or address shall be hereafter designated in writing by either of the parties given by the procedure set forth above. 2. The date of giving such notice shall be deemed to be the date of mailing thereof. 3. Billings for and payments of water bills may be made by regular mail. 4. The City shall notify the Purveyor and Purveyor Committee in writing, not less than one hundred eighty (180) days in advance of the effec- tive date thereof, of proposed amendments to the City's Comprehensive Regional Water Plan that would have a financial impact on the purveyors. 5. In addition, the City shall send to the Purveyor and Purveyor Committee a copy of its proposed annual Water Capital Improvement Program 31 Version B Corrected 2-3-82 (CIP) not less than 60 days prior to submittal to the Seattle City Council. VIII.B. Severability The purpose of this Contract is to provide by long-term planning, certainty for both the City and the Purveyor through adoption of orderly plans calling for the expenditure of vast sums of money for regional water supply facilities. It is the intent of the parties that if any provision of this Contract or its application is held by a court of competent jurisdiction to be illegal, invalid, or void, the validity of the remaining provisions of this Contract or its application to other entities, purveyors or circumstances shall not be affected. The remaining provisions shall continue in full force and effect, and the rights and obligations of the parties shall be construed and enforced as if the Contract did not contain the particular invalid provision, provided, however, if the invalid provi- sion or its application is found by a court of com- petent jurisdiction to be substantive and to render performance of the remaining provisions unworkable and infeasible and is found to seriously affect the consideration and is inseparably connected to the remainder of the contract, the entire Contract shall be invalid. VIII.C. Consent Whenever it is provided in this Contract that the prior written consent or approval of any 32 party or the Purveyor Committee is required as a condition precedent to any actions, in each such instance said consent or approval shall not be unreasonably withheld, and in each such instance where prior consent is sought, failure of the party to respond in writing within sixty (60) days of the request shall be deemed as that party's consent or approval unless otherwise provided for herein. This provision does not apply to amendments of this Contract. VIII.D. Initial Implementation The intent of both parties is to work together to take such actions as are necessary to implement full compliance with this Contract in as expedi- tious a manner as possible, provided that such full compliance shall occur no later than three (3) years after the effective date of this Contract. VIII.E. Emergency Situations Nothing in this Contract shall be deemed to preclude either party from taking necessary action to maintain or restore water supply in emergency situations, in accordance with Section I.D., and such action shall not be deemed a violation of this Contract. VIII.F. Purveyors Not Joint Venturers - Individual Liability This is not an agreement of joint venture or partnership, and no provision of this Contract 33 shall be construed so as to make the purveyors in- dividually or collectively partners or joint ventur- ers with each other or with the City. Neither par- ty is an agent of the other, nor is any purveyor the agent for the City or for another purveyor. Neith- er the City nor any purveyor shall be liable for the acts of the other in any representative capac- ity whatsoever. 34 SECTION VIII. DEFINITIONS VIII.A.

H v EXHIBIT III -C OPTION TO AVERAGE COMMODITY BILLINGS The undersigned Purveyor hereby agrees to have its com- modity billings averaged with those of other purveyors who participate by exercising an identical option. The averaging will be performed by totalling the dollar amounts of the old consumption billings and the new consump- tion billings of all purveyors who participate in this option. Any individual purveyor's commodity billing under this option will be the purveyor's percentage of the total consumption of participating purveyors times the total dollar amount computed above. In any case, the total amount billed under this proce- dure shall equal the total amount which would have been billed to all of the individual participants during the same billing period. PURVEYOR: BY: BY: BY: ATTEST: DATE: ORDINANCE/RESOLUTION 41 EXHIBIT III -H DEMAND CHARGE METHODOLOGY The demand charge and method of application thereof shall be as follows: 1. The policy of the City is to supply water to whole- sale water purveyor customers (municipal water districts, other municipalities, and nonprofit water associations) at the twenty-four hour average flow rate. Water purveyors are expected to provide or pay for storage for peaking rates above such average flow rate. 2. A demand charge will be applicable to water purveyors who are found to have deficient storage as determined in the following paragraphs. 3. The water services (master meters) to purveyors will be monitored by the City to determine applicability of the demand charge. Demand metering equipment will be installed on master meters to purveyors at City expense. 4. Water services to a purveyor on a uniform segment of supply line may be considered as one water service in calculating storage deficiency. 5. A "day" for purposes of this schedule commences at nine a.m. and ends at nine a.m. the following calendar day. 6. The demand factor for each water service is deter- mined by dividing the fifteen -minute peak flow rate by the twenty -four-hour average flow rate of the same day. 42 7. Thei ten maximum flow days for each water service will be used to determine the average demand factor from which storage deficiency will be calculated. The average demand factor is the average of the demand factors of the ten maximum flow days for each water service. 8. A demand charge for each water service shall be applied only when the average demand factor exceeds 1.3. 9. The deficient storage volume of each water service for demand charge calculation rate shall be S = 0.22(F -1)Q; where S = storage deficiency in gallons, F = average demand factor and Q = average daily quantity of water in gallons used in the ten maximum flow days for each water service. 10. The demand charge shall be calculated by applying a storage deficiency rate per month per thousand gallons of deficient storage. The total purveyor demand charge shall be the sum of the demand charges for each water service. 11. The demand charge will be calculated in the fall of Path year based upon evaluation of the summer months (June, July and August) water delivery flow rates and upon the storage deficiency rate in effect at the time that those flows occurred. The monthly storage defi- ciency demand charge billing shall commence in January and continue for one calendar year until the following January at which time a new charge, if any, shall be applied. 43 12. Peak flow rates through master meters will be moni- tored during the summer months; however, if peak flow rates create adverse hydraulic conditions, demand metering may be applied year-round, after reasonable notice to purveyor customers. 13. Purveyors may use other sources of supply approved by the Superintendent of Water such as interconnection with other purveyors' systems or development of wells for the 14. If summer water supply peaking purposes subject to provisions of this Contract. purveyors formulate approved cooperative operating agreements, their services on uniform segments of supply line may be considered as one service in determining demand charge. 15. Peak flows caused by major accidents in a purveyor's water system will be excluded in deter- mining the demand charge. Peak flows caused by other unusual situations may also be excluded at the discretion of the City. Documentation of such incidents shall be provided by purveyors to the City within thirty (30) days after an incident. 16. Artificially created daily flow rates which differ substantially from customers' daily consumption may be disallowed in calculating the demand charge. 17. Approved electrical sensing circuits (e.g. for telemetering) from City master meters may be made available to purveyors on a reimbursable cost basis. Such circuits shall be installed and main - 44 tained by the City; there will be no need for purveyors' representatives to enter City chambers. 18. The demand charge for a certain master meter (s) may be excused if lower pressure water (or gravity flow water) replaces City -pumped water (or higher flow water), provided that the peak flow rate through this service does not exceed the demand rate threshhold which would occur_ without the replacement of water service flow. 19.

Fraser dUu 1VII1. WASHINGTON 98004 TELEPHONE (206) 682.5300 Re: Temporary Intertie With Water District Mo. 125 Dear Mr. Fraser: • In response to your August 12, 1985 letter (copy enclosed). I as resubmitting plans for a temporary intertie between the City of Tukwila and Water District So. 125. All of your comments referred to the intertie at Interurban Avenue South and 42nd Avenue South. After construction of a major transmission main within the District and testing of it's effect, that intertie will not be necessary and has been dropped from our plans. However, the intertie at South 131st Place and 44th Avenue South is still necessary to provide adequate fire flow during the time the Interurban Bridge across the Duwamish is being reconstructed. That intertie is shown on the attached plans as Schedule B of Contract 85-3. I request the City allow construction of this intertie to pro- ceed and the facilities to remain in place during the bridge construc- tion. The Water District will remove the intertie upon completion of the bridge. Th• Water District. will serve the normal needs of the area through two PRY sources from other pressure zones. The PRY in this intertie will be set to open only when fire flow to one of the major customers in the area exceeds 2,400 GPM. It is estimated that a maximum of 800 GPM will be taken during that peak demand. We fully expect that it will never be used. Tukwila's ten inch main will be live tapped, so no disruption of ser- vice is expected. In addition, backflow through the intertie will be provided by a check valve and all flows to Water District So. 125 will be metered. The District is prepared to pay Tukwila for any water taken at Tukwila's standard rates in effect at the time. Some water may be used during set up and testing of the intertie.

Last summer, a permanent intertie was constructed at Interurban Avenue South and 52nd Avenue South. Correspondence to Water District 125 through Phil Botch and Associates required that certain paper- work be provided the City and approval for activating this permanent intertie be obtained through the Tukwila City Council prior to its use. Roger Eberhardt of Phil Botch and Associates is now putting this information together so it can be submitted to our City Council in the next two to four weeks. (See Phil Fraser's letter of August 8, 1985 for the permanent intertie). Currently, the construction of a temporary intertie at the inter— section of South 131st Place and 44th Avenue South has been approved to be used on an emergency basis. Also, wter District now producing requested paperwork and approvalsthrough the Seattle Water Department to assure the City that all conditions of the purveyor's agreements between Water District 125, Tukwila and the Seattle Water Department have been met. It has been assumed by staff that because the intertie located at South 131st Place and 44th Avenue South is of a temporary nature (tied to the timeline of rebuilding the Interurban Avenue bridge - King County is scheduled to build it within one year, beginning April of this year) that City Council approval is not necessary for such a temporary use of the City's water system. Once this King County bridge has been constructed this intertie will be abandoned by Water District 125 and the City of Tukwila. cc: City Engineer Roger Eberhardt, Phil Botch & Assoc.

SEATTLE, WASHINGTON 98188 City of Tukwila 6200 Southcenter Blvd. Tukwila, WA. 98188 Attn: Ted Uomoto Re: City of Tukwila/Water District No. 75 Water Intertie RECtivED max Wpre alYGfu ill 1960, Dear Mr. Uomoto: This is a reply to your April 8, 1980 communication pursuant to several discussions that we have had about water service between our two utilities. The current configuration existing at S. 180th St. and Andover Park West, contemplates water flowing in either direction be- tween Water District No. 75 and the City of Tukwila. This concept was recommended by Mr. .Segale of the Segale Industrial Park. His thoughts were that a somewhat better fire rate might be obtained if there were two sources of supply. I specifically mention this because, with the inplications of demand type service proposed -from our two utilities, there is less likeli- hood that water will flow from Tukwila to Water District No. 75. The bypass at this location will become of emergency na- ture only. We have reviewed the requirements for implementing demand ser- vice between_our two utilities. We forsee about four areas that must be addressed as follows: A feasibility study with a computer print-out will give us a hydraulic analysis of your system. This will be necessary. Such a study was performed several years ago. Since the original study, the Segale Indus- trial Park has been developed, the McCann Industrial Park has been developed, and a number of additions and betterments have been accomplished in our two systems. In fact, there is now an intertie between the City of Tukwila and the City of Renton and another intertie between the City of Tukwila and the City of Kent. The hydraulic analysis must therefore be updated to deter- mine the implications of these changes. It would be our impression that this work should proceed immediately because much of our design is dependent upon this result. We estimate the cost of this study, including about six different flow configurations, or conditions a flow, at about $9,400. The Segale Industrial Park has been having internal.prob- lems due to a "locked.system" resulting from the several pressure reducing valves that they have. The changes that we contemplate will necessitate a hydraulic opera- ted pressure relief valve to prevent excessive pressures from occuring within our system. A design has been per- formed for this equipment. We estimate the cost of this installation at $5,600. We have reviewed the print-out of the City of Seattle monitoring that was performed on the City of Tukwila. system in the year of 1979. We find that the major de- mand on your system occurs in the morning.. Water District No. 75 experiences a secondary peak at about this time. This indicates the need for demand meteringand print- outs so that the flow can be monitored to avoid a respon- sibility to the City of Seattle by Water District No. 75. We estimate the cost for this metering equipment at about $1,500. In our original proposal for providing service to you several years ago, we indicated the necessity for "balanc- ing" your meters. The reason for this is that the com- puter print-out indicated that a nurflber of your meters were non-operative during peak demand. This will occur if a pressure reducing valve is not properly adjusted and does not give recognition to the elevation at which it is installed. It•will be necessary to "fine tune" the adjustment of all pressure reducing valves in the system so that proper flow can be obtained from each unit during peak demand. This work was previously accomplished by your Water Superintendent, Ted Freemire. Ted has done such an excellent job at this, I thought that we might prevail on him to continue this work. We anticipate some involvement from our office during the time that Ted is making these adjustments. We estimate this cost at $1,200. The total estimated cost for adjustmants and "conversion" is estimated at $17,000. It is our suggestion that Water District No. 75 pay for the cost of the pressure relief valve in the Segale Industrial Park and share the cost of the demand metering. On this basis,. the City of Tukwila would pay $11,250 and Water District No. 75 would pay $6,350 After the proposed.system is operative, it is our suggestion that the City of Tukwila pay the standard charge for water through the meter as previously prescribed. We will appreciate your consideration and concurrence in this proposal.

For 1995 the BUYER shall pay to the SELLER for all water delivered at the rate of $1.35 per 100 cubic feet, which is the Seattle Water Department summer new water rate for 1995. The rate charged to the BUYER shall be adjusted each year on January 1st using the method described as follows. The rate charged by the SELLER shall be the larger of the following: 1) the current Seattle Water Department summer new water rate (in dollars per 100 cubic feet) or 2) [$1.24 per 100 cubic feet] times [the current City of Renton retail commodity rate (in dollars per 100 cubic feet)] divided by [$1.68 per 100 cubic feet]. 3) Metering. RENTON and TUKWILA shall each provide, and own and maintain, an appropriate metering device to measure the water flowing through the intertie. An interlocal agreement may be prepared to allow one party to operate and maintain the intertie and distribute the costs equally between the both parties. As soon as either becomes aware of flow of water through the intertie that party will notify the other. If prior notification is feasible, the party requesting the water shall provide a description and documentation of the emergency condition to the other party. Each party will monitor its meter(s) on a regular basis. 4) Priority and Continuity of Service. The determination of whether water is available for emergency sale shall be at the sole discretion of the party delivering (selling) the water. In the event of a condition requiring restrictions on the delivery of water, the party delivering the water shall have the right to restrict or interrupt service.

Individual analysis reports are also provided for you to forward onto each participant these reports have not previously been sent to you. The summary reports are for your use. They provide lead and copper analysis results for standing and flushed samples, when applicable, in addition to sodium, pH, and specific conductivity from the standing sample. Standing and flushed samples are indicated by the s orf following the constituent analyzed. The Rept column indicates the status of the analysis results and the corresponding letter which is printed: o, okay, lead and copper levels below the action levels; 1, lead levels exceeding the 15 ppb action level. As before, for individual customers who exceed the EPA action limits of 15 ppb (µg2) lead and/or 1.3 ppm (mg/L) copper, you may want to contact them directly.

OBJECTIVE The objective of this Operations Plan is to ensure satisfactory management of the water system operations through proper and efficient procedures. The use of this plan will help guarantee that improvements identified in the water comprehensive plan will be properly operated and adequately maintained to ensure the continued viability of the system. The City's Water Utility with the assistance of this operations program will be better able to consistently provide reliable, high-quality drinking water. The development of this document is intended as a guideline for routine use by the Tukwila Water Utility employees. II. PLAN CONTENT/PROG'' ELEMENTS An operations program is required for all water systems by WAC 248-54-195. Each utility must develop a basic operations program tailored to specifically meet the needs of the utility. The level of detail and content of the program depends upon the size, complexity, and performance of each particular water system. Utilities are encouraged to develop an operations program that provides the level of detail needed to adequately operate the water system. In addition each water system has its own unique characteristics which require specific details continually identified through "on the job" experience. This operations manual contains the following major elements as part of the basic operations program: O Water System Responsibility and Authority O System Operation and Control O Equipment, Supplies and Chemical Inventory O Water Quality Monitoring 1 O Emergency Response Program O Cross -Connection Control Plan O Water Conservation III. LOCATION The City of Tukwila is located south of Seattle, Washington and east of Seattle -Tacoma International Airport. It is bordered on the north by the City of Seattle, on the east by the Cities of Renton and Kent, and on the south and west by the City of Seatac and unincorporated King County. IV. iISTORY OF MUNICIPAL UTILITY In the late nineteenth and early twentieth centuries, scattered water wells and the Green River provided water supplies for the early residents in the Tukwila Area. The Tukwila Public Water System began in 1929 when a six-inch diameter steel water main was constructed from Beacon Hill in Seattle south under the Duwamish River to the Tukwila North Hill Area. In 1964, a local improvement district (LID) was formed in conjunction with the development of the Greater Southcenter Area. Federal funds from a H.U.D. Grant Program were used to complete a major water system improvement to the north section of Tukwila through which most of the old existing pipes were replaced. The growth of the Tukwila System and ordinances administered by Department. Developers typically mains to their property lines. is controlled by City codes the Tukwila Public Works are required to extend water The Tukwila Fire Marshall designates the fire flow required for each type and size building. The developer must then construct a water main the designated capacity as part of the development and accordance with the comprehensive plan. of of in Maps and listings of water improvement projects are referenced and shown in the Tukwila 1991 Water Comprehensive Plan as adopted by City Council Resolution No. 1264. Other references used are from the TMC (Tukwila Municipal Code) and AWWA (American Water Works Association). 2 CHAPTER TWO WATER SYSTEM POLICIES, RESPONSIBILITY, AND AUTHORITY I. AUTHORITY, MANAGEMENT, AND PERSONNEL The City of Tukwila is an optional municipal Code Class City and is authorized by the State of Washington under RCW 35.27 to operate and maintain public utility systems. The water utility is a group "A" system ID no. 89500F as designated through the Washington State Department of Health. Special utility districts lying inside the City Limits are granted a franchise by the City however the City reserves the right and authority to acquire those utility lines and facilities and provide water service to all water users within the City. The City operates under a mayor/council form of government with an elected mayor and seven (7) elected council members. The City Council makes and establishes City policies that govern the operation of the Water Department by adopting ordinances and resolutions. The Tukwila Water Utility operates under the direction of the Public Works Director. The Public Works Operations Manager, Division I, oversees the supervisory responsibilities for the Water Utility's operation and maintenance as well as sewer, surface water, and streets. Day to day activities are conducted by the Water Crew Chief who reports to the Public Works Operations Manager. The Water Crew Chief also oversees water quality monitoring and cross -connection control. The Public Works Engineer covers budgeting, new or upgraded system design, operations analysis, and the construction of capital improvements as outlined in the Water Comprehensive Plan. FIGURE I illustrates the organizational structure of the Water Utility. The Public Works Department is located in the office building east of City Hall. The Public Works Department address is 6300 Southcenter Boulevard. All administration, engineering, and plan review, is accomplished at this location.

OPERATIONS OBJECTIVE The objective of this component of the plan is to evaluate systems operations, identify preventive maintenance tasks, and establish emergency operation procedures. In order to accomplish this, it is necessary to fully understand the total system and each key component of the system separately as well as in relation to the entire system. Therefore, each component will be identified and the routine and preventive maintenance requirements discussed. II. GENERAL SYSTEM OVERVIEW The City of Tukwila purchases its entire water supply from the City of Seattle through wholesale meters at six (6) separate locations. The distribution system is fully metered for irrigation and potable uses. Storage is available at a two million -gallon concrete tank located on the North. Hill. The pump station at the reservoir allows water to be fed into two different pressure zones. Telemetry equipment has been installed at the reservoir and at supply stations 11, 13, and 15, to monitor system status points and control the supply station valves. The control system sets the supply station valves to open or close thus invoking reservoir booster pump operation when the pressure is at or below the pump start setpoint. III. SYSTEM COMPONENT DISCUSSION/ROUTINE OPEC ION/PREVENTATIVE MAINTENANCE This section the procedur maintenance system are: discusses each of the system components, e for routine operation, and preventative procedures. Main components of the City's A) Source, B) Telemetering, C) Conveyance Piping, D) Pressure and Pump Station, Service Meters, I) Zones/Isolation Valves, E) Reservoir F) Valves, G) Fire Hydrants, H) Office Procedures, J) Property. The 6 major water system components are shown in Figure II. A. SOURCE A-1. GENERAL DESCRIPTION The source of water for Tukwila comes from the City of Seattle's Cedar River Watershed located southeast of North Bend in the foothills of the Cascade Mountain Range. The Tukwila Water System draws water from the Seattle Conveyance System at (6) separate locations. A water meter and pressure reducing valve (PRV) are used at each source point to measure water flow and to reduce the water pressure from 200 psi (Seattle) to about 145-150 psi (Tukwila). If the Cedar River water supply is cut off, the City is supplied with water from the Tolt River source. Backup water is also available through interties with neighboring water districts. The 48 -inch West Seattle Water Main is tapped in two locations north of Tukwila's Allentown Area (Meter Station 11 and Meter Station 168). Water flows south through a 10 -inch meter, 10 - inch PRV and 5000 feet of 18 -inch ductile iron pipe to feed the north part of the Tukwila distribution system. Station 168 supplies the north area including the East Marginal Way corridor through a 12 -inch PRV. The 60 -inch Seattle West Valley Water Main is tapped in one location west of I-5 (Meter Station 16), two places in the Southcenter Area (Meter Stations 13 and 15) and one near West Valley Highway (Meter Station 14). These taps supply the central and south portions of the Tukwila System. The Cedar River pipeline is tapped at Beacon Avenue South and Leo Street for supply station 6. This tap supplies customers east of I-5 in the old District #25 area. Tukwila's first supply station (No. 12) which includes 9 customers was transferred to Skyway Water & Sewer District in 1992 and is no longer part of the Tukwila System. In 1981 The Tukwila City Council authorized the mayor to sign the longterm purveyor's contract "version B" for water supply offered by the City of Seattle. Under the contract, Seattle guarantees Tukwila a reliable water supply. In exchange, Tukwila is bound to purchase most or all of its water from Seattle under the contract until the year 2012.

OPERATIONAL PROCEDURES The operational procedures for source water involve regulating and maintaining the six inlet supply stations. There are two distinct periods of operation for the stations: "Summer" (consisting of June, July, and August) and "Normal" (defined as September through May) . These time periods are based upon the Seattle Public Utilities's definition of peak water flows. Seattle will charge a demand fee during the summer for peak water used based on the Utility's effective deficient water storage. During all months except June, July, and August of each year, the supply stations can be operated without concern for peaking flows. In this mode of operation, all stations act as a standard PRV and operate under pressure control. During the "Summer" period the stations are set to flow control mode where all changes in the controlled flow rates are made by authorized personnel at 9:00 A.M. each day. Recommended settings for the six inlet meters during "Summer" mode is set forth below: Supply Meter 6 - Not controlled. Supply Meter 11 - When this station is set in flow control mode, the RTU limits the flow to the setpoint which is typically maintained above 500 gpm. Variation occurs depending on demand needs or the current year water restrictions. Flow setpoints are set remotely at the Minkler Shops master water computer console. Supply Meter 13 - Controlled the same way as station 11. This supply station is considered the primary feed to the reservoir. Because of its close proximity to station 15, 13 is set as the lead station. Depending on demand needs the setpoint should be 8 Supply Meter 14 - Supply Meter 15 - Supply Meter 16 - maintained between 500 and 750 gpm. Not controlled. Since this station is treated as the lag station flows may be set from 0 to 250 gpm or else left in PRV mode. Not controlled. A-3. PREVENTIVE MAINTENANCE Throughout the year each supply station is inspected on a monthly basis by maintenance personnel. The general condition of the station is checked including the inlet/outlet pressures, PRV and pipe apparatus, solenoids, RTU/radio, dehumidifier, and lights. Also the strainer screens are removed, inspected, and cleaned for debris. Every 5 years all rubber components in the main pressure reducing valve and the pilot valve are replaced. B. TELEMETRY B-1. GENERAL DESCRIPTION A water telemetry and supervisory control system has been installed. The system includes automatic control equipment at three supply stations, and one at the reservoir in addition to the master telemetry unit and control computers at the Maintenance Facility. The system consists of a control computer that performs normal control functions such as data logging, telecommunications, and alarm functions. The data computer stores all historical data, trends, and graphs for ready access. Data Radios & the remote telemetry units (built by RUGID Computer) are installed at supply stations 11, 13,15 and at the reservoir pump station. B-2. OPERATION AND MAINTENANCE Operation of the supply and control system involves a summer scenario as defined previously under the "SOURCE" section for 9 controlling flows in the system. Normal operation using pressure control mode generally only requires maintenance of the data files. The historical data files need to be renamed every six months in order to keep their size manageable. Frequent tape backups of the data is recommended. At times the supply station RTU programs may need reloading or trouble -shooting depending upon the circumstances involved. Below is the procedure for using a laptop computer to begin diagnosing the problem. More detailed information on these programs is available in the Micro TCS notebook that came with the RUGID software which controls the system. 1) PROCEDURE FOR USING LAPTOP COMPUTER @ SUPPLY STATIONS a. Disconnect Serial connector between TCS & DataRadio. b. Using a 9 -pin Serial cable, connect computer to the TCS unit. c. Connect computer to power source & turn on computer. d. At menu prompt, select Smartware Communications or ProComm. e. Choose menu item desired for Supply Stations. f. Once in Terminal Mode use the following keystrokes: CNTRL KKK (establish link to RUGID) C (command mode) LIST (lists program) CLEAR (clears out variables) RUN (begin program operation) Press <F10> to exit Smartware Communications Menu. g• h. Power down, disconnect computer & remove serial cable 10 i. Reconnect TCS to Data Radio. C. PIPES C-1. GENERAL DESCRIPTION The City's transmission and distribution piping consists of about 190,000 lineal feet. Most of the pipe is 6 -inch or larger but 2 -inch and 4 -inch lines exist particularly in the Allentown area (formerly Water District 25). The majority of the lines are 8, 10, or 12 -inch ductile iron pipes although some of the older pipes are cast iron or steel. Detailed information about needed improvements is included in the City's Comprehensive Water Plan which also contains the 1:1000 scale water plan map showing pipe size, type and location. C-2. OPERATING PROCEDURES Operating procedures consist of first knowing where the pipes exist. The water plan map and associated as-builts are utilized for locating and working on the City's piping when required. Any discrepancies identified during repairs are noted and brought to the Engineering office for inclusion on the formal system maps. A set of 1:200 scale Kroll maps also exists to better determine the location of valves, hydrants, blowoffs, interties, and PRVs. It is important to implement operational practices that will protect the system's water quality. Routine flushing and periodic inspection and/or testing at water main appurtenances is normally done one or more times during the year. C-3. PREVENTIVE MAINTENANCE The most important preventive maintenance strategy relating to the City's pipes is the replacement and installation of pipe which meets the City's water construction standards. As long as Class 52 ductile iron pipe and type K copper services are specified on projects, there is normally fewer problems with 11 the system. Good construction practices are a must, and care must be taken when handling pipe to preserve the integrity of the protective coating and lining. Water from the Seattle Public Utilities has a history of being very corrosive because of its low mineral content. This factor, in addition to Tukwila's wet corrosive soils, has resulted in the premature deterioration of old existing steel mains and galvanized steel services. D. PRESSURE ZONES/ISOLATION VALVES D-1. GENERAL DESCRIPTION The City currently has two pressure zones: The North Hill pressure zone and the 360 pressure zone. The North Hill reservoir is equipped with two separate pairs of pumps, one pair supplies each pressure zone. At the time the North Hill reservoir was constructed, 18 one-way check valves were installed at approximately 175 feet above mean sea level to form a separately controlled pressure zone on the North Hill whenever the North Hill pressure zone pumps are operating. A zone similar to the North Hill has been isolated at Supply Station 16 near Crystal Springs Park, by way of an isolation check valve on Klickitat Drive. D-2. OPERATING PROCEDURES Please refer to the North Hill reservoir and pump station for the operation of the isolation valves associated pressure zone through the reservoir control system. D-3. PREVENTIVE MAINTENANCE Verify that all North Hill Zone isolation check valves are set for one-way operation on a yearly basis. Always follow safety procedures for confined spaces when entering the isolation valve manholes. The valves should be overhauled every 5 years in accordance with Cla-valve manufacturer's recommendations. 12 E. NORTH HILL RESERVOIR & PUMP STATION E-1. GENERAL DESCRIPTION The City of Tukwila completed the construction of a 2 MG concrete prestressed water tank and pump facility in 1990. As part of the reservoir installation, the North Hill residential area was divided into a (separate) pressure zone by way of 18 one-way isolation valves located approximately along the 175 - foot elevation contour. This upper residential zone is fed by either or both of the variable speed pumps. The lower elevation system can be fed by either or both of the two large fixed speed pumps. The high capacity fire pump can supply both zones if a fire demand occurs. North Hill Pressure Zone Pumps: Two variable speed, vertical turbine pumps have been installed at the reservoir for the purpose of maintaining adequate pressure to the North Hill residential area. These identical pumps are rated at 490 gpm at 182 feet of Total Dynamic Head (TDH). 360 Pressure Zone Pumps: Two constant speed, vertical turbine pumps provide the alternative of pumping water from the reservoir back into the 360 (hydraulic grade line) pressure zone to provide supply and storage on a demand basis. These identical pumps are rated at 1090 gpm at 141 feet TDH. High Capacity Pump: A high capacity fire pump has been installed to augment system pressures in the event of excessive high demand such as fire control. The pump is rated at 4,000 gpm at 141 feet of TDH and can supply either zone. Because of the pump's extraordinary capacity, it is intended to augment the system only under emergency needs where there is a failure in the Seattle water supply. The power switch shall remain off at all times unless otherwise directed by the Mayor, through the Public Works Director or Fire Chief. Isolation Valves: Isolation between the North Hill and the 360 pressure zones is accomplished with 18 Cla-valves consisting of a diaphragm -actuated globe type A 81G-02, 125 class. The valves are installed in a 48 -inch shallow manhole. 13 Reservoir Control: An Allen-Bradley PLC5 control system has been installed at the reservoir pump station. The North Hill Reservoir and Pump Station control system is not linked to the water distribution control system but it does monitor and respond to pressure variations in the distribution system resulting from Demand Control changes. In addition the Demand Control System can read reservoir level, inflow, outflow, and 360 zone pump status, by way of their respective analog outputs from the reservoir PLC. E-2. OPERATION & MAINTENANCE It is important that the water levelin the reservoir be maintained at sufficient levels to ensure adequate equalization, standby and fire storage at all times while allowing proper turnover of the water. The level in the tank should not fall below 50o during regular operation. a) GENERAL OPERATIONAL PROCEDURES - outlined as follows: 1. Verify the proper position of all manually operated valves, including those outside of the pump station. 2. Verify that all set points are correct. 3. Operation of the North Hill (high) zone pumps: i. The Lead/Lag position of each pump should be exercised a frequent and regular basis. This is accomplished by the 1-2 switch designating either pump 1 or 2 as- the lead. Upon turning the 1-2 switch, the PLC will immediately make an incremental transition from one pump to the other in order to keep a constant pressure maintained to the zone. ii. At least once a month, both pumps should be shut down completely for 24 hours for the purpose of maintaining water quality near the one-way valves. Turn the H -O -A switch to the OFF position for pump 1 and pump 2 of the North Hill Zone. This allows the North Hill to 14 be fed directly from the 360 zone thus opening the one-way isolation valves and flushing supply water directly toward the upper zone. This routine may need to be done weekly during the summer in order to reduce the likelihood of detectable coliform counts. 4. Operation of the 360 zone (low zone) pumps: i. Since these pumps operate on demand the Lead/Lag switch can be changed on an as -needed basis. Always verify the operation of the multi -function valve(s) when one or both pumps are running. The multi -function valve(s) will open to allow recirculation into the reservoir to match the incremental demand while maintaining the set point pressure. Verify the proper operation of the flow meter(s) with flow out of the pump station. 5. Operation of the reservoir filling function: i. The filling rate (gpm) of the tank can be modified through the Specter anunciator panel on the front of the cabinet. First check that the Reservoir Fill M -A switch is in the "A" position. To modify the filling rate press the <LOOP/SCAN> button until the display shows "RES FILL" then press <UP ARROW> or <DOWN ARROW> to display setpoint status "SP - GPM". Press the <CHANGE/ENTER> and arrow keys to achieve the desired GPM flowrate, then press <CHANGE/ ENTER> again to accept the value selected. For manual filling, simply turn the M -A switch to the "M" position and slowly begin increasing the low zone multi -function valve dial keeping an eye on the low zone system pressure and flow readings. 15 b) DISINFECTION New storage facilities and facilities which have been repaired, cleaned, or had cathodic protection installed must be disinfected. Always disinfect water storage facilities whenever there has been any opportunity for contamination. NOTICE: Before entering a water storage facility for any reason, personnel must observe the following safety precautions: i. Test the atmosphere in the tank for toxic and explosive gases and for adequate oxygen. Alarm devices which are activated whenever unsafe air is encountered should be employed. ii. Provide adequate ventilation, especially when spraying. If ventilation is inadequate a self- contained breathing apparatus is needed. iii. All persons entering a tank must wear a safety harness. iv. One person trained in tank rescue procedures, safety and first aid must remain at the tank entrance observing the actions of all people in the tank. An additional person must be readily available to help the person at the tank entrance with any rescue operation. After inspection of the lid supports and general cleaning of the fill apparatus is performed, spray or brush the interior of the storage facility with 200 mg/L chlorine solution, working toward the hatch. When the tank is filled with new water, the chlorine residual must be tested for use. c) ESSENTIAL ALARM The following alarm conditions shall initiate an essential pump station alarm: i. Any essential pump alarm. 16 ii. High -high reservoir level. iii. Low -low clearwell level. iv. Fire pump inlet valve failure. v. Any analog input signal detected out of range. vi. Programmable Controller failure relay is energized. d) NONESSENTIAL ALARM The following alarm conditions shall initiate a nonessential pump station alarm: i. Any nonessential pump alarm. E-3. PREVENTIVE MAINTENANCE Weekly visits to the reservoir shall include checking that the upper zone pumps are still running, changing the lead and lag functions of each pump, inspecting light bulbs and indicators, recording the upper zone meter reading, and checking the general area for vandalism or other conditions. The tank itself shall be cleaned and disinfected every 2 years (See above section entitled DISINFECTION). F. VALVES F-1. GENERAL DESCRIPTION Tukwila maintains a network of valves that can isolate any portion of the system during an emergency, during construction, or at the time of repair. All valves installed in the City have been installed in accordance with the standards of the AWWA C-500 specification. Gate valves are to be resilient seat, opening counter -clockwise with a non -rising stem and standard 2 -inch (2") square stem nuts. 17 F-2. OPERATING PROCEDURE Valves are opened or closed by removing the lid on the valve box then turning the operating nut on the top of the valve with a valve operating wrench. The hydraulic valve exerciser is employed as needed. Operation of the large valves particularly in the 360 -zone where the pressures are 150 psi require operation in such a way as to prevent water hammer. F-3. PREVENTIVE MAINTENANCE All valves are to be exercised annually and checked for water tightness. G. FIRE HYDRANTS G-1. GENERAL DESCRIPTION Tukwila has approximately 300+ City -owned hydrants throughout the water service area. Hydrants are shown on the 1:1000 scale water comprehensive plan map. Each public hydrant is assigned and labeled a hydrant number. The current Tukwila standard hydrant is a compression -type with oil reservoir conforming to AWWA specification C502-54. The hydrant is equipped with two 2-1/2 inch hose ports and one 5 -inch Stortz pumper discharge port. Hydrant color conforms to the "Rustoleum" #659 yellow gloss or approved equal. Bonnets and ports for hydrants are painted red for flows up to 500 gpm, orange for hydrants with flows from 500 to 1,000 gpm, and green for hydrants with flows greater than 1000 gpm. The current fire hydrant assembly standard is shown in FIGURE III. G-2. OPERATING PROCEDURES Generally, the most use and operation of the City's fire hydrants will be by the Tukwila Fire Department. The top operating nut is to be turned strictly with the use of a hydrant wrench. Check to see that all nozzle caps are secure. Unauthorized use of City fire hydrants is deemed theft III (TMC title 14.04.250). 18 X000 �I 5" STORTZ 18" • FIGURE 111 FIRE HYDRANT TO BE PAINTED WITH TWO COATS OF " RUSTOLEUIr' MULOW GLOSS.

PREVENTIVE MAINTENANCE The main maintenance items related to fire hydrants are: • Painting - About 100 hydrants are to be painted every year on a continuous rotation basis to cover all hydrants within 3 years. • Visibility - The area surrounding the hydrant should be kept free of debris and vegetation. Hydrants and guard posts shall be in plain view for a distance of fifty feet in the line of vehicular approach (TMC 14.24.050). • Testing - The Fire Department may periodically test hydrants to ensure that pressure and flow is adequate. All hydrants shall be operated annually to verify that the main operating valve is functional and that no problems exist. A record of the date of testing for each hydrant is kept on the appropriate form. • Flushing - All dead-end hydrants and blow -offs should be flushed periodically to ensure the flow of fresh water to nearby services. Flushing is not normally done during water restrictions unless absolutely necessary. H. SERVICE METERS H-1. GENERAL DESCRIPTION All domestic and/or industrial consumption of water shall be metered. The City of Tukwila has about 1040 residential meters and 660 commercial/industrial meters (1993). Flow is measured in cubic feet (cf). Meters range in size from 3/4 inch residential to as large as 6 inch. Water service connections to other than single family residential shall be a minimum of 1 inch. Compound meters have a greater accuracy range and are the City's standard for meters 2 inches and larger. 19 H-2. PREVENTIVE MAINTENANCE Water meters are currently tested on the following schedule: 3/4" & 1" - 7 years (As time & manpower allows) 1-1/2" - 5 years 2" - 2 years 3" & 4" - 2 years 6" & up - Annually I. OFFICE PROCEDURES The City of Tukwila has a policy and procedures manual for all employees which is available through the personnel office. Tukwila has been using the NARUC system for reporting utility maintenance costs. In 1994 a computerized maintenance management system (Micro Maint. from Reliable Technologies) was implemented to track and schedule maintenance activities as well as record maintenance procedures and associated costs. Meter readings and billings are done every month. A procedures checklist for utility billings is shown in FIGURE IV. J. PROPERTY J-1. GENERAL The Tukwila Water Utility has one parcel of land at 15045 57th Avenue South where the North Hill reservoir and adjacent pump station facility are located.

SUPPLIES The water utility keeps a stock for virtually any emergency throughout the system. This computerized on the maintena (Micro- Maint). III. VEHICLE MAINTENANCE of supplies to be ready or maintenance need supply inventory is nce management system The total City fleet of vehicles including the Water Department vehicles is maintained by the Tukwila Equipment Rental Department. This department is responsible for the purchase, maintenance, surplus, and disposal of all fleet vehicles. 22 CHAPTER FIVE WATER QUALITY MONITORING I. OBJECTIVE A public water system is obligated to furnish its customers with healthful, potable water. Healthful water is free of pathogenic organisms, poisonous substances, and excessive amounts of mineral and organic matter. Potable water may be water defined as free or nearly free of color, turbidity, taste and odor. It has a moderate temperature and is aerated. To assure the greatest possible protection to health, enjoyment and usefulness, standards of acceptability have been established which define not only the types of impurities a supply may contain, but also the maximum permissible concentration of these impurities. These standards of acceptability are set forth in the "Rules and Regulations of the State Board of Health Regarding Water Systems, as outlined under WAC 248-54-165" and the Requirements for sampling, testing, reporting and maximum coliform bacteria, inorganic chemicals, and secondary contaminants are included in these rules and regulations. When water samples indicate that maximum contaminant levels for coliform bacteria and/or inorganic chemicals are exceeded, the rules and regulations require immediate action because the public health may be endangered. Samples which indicate the secondary contaminant levels have been exceeded do not require immediate action because they do not endanger the public health but may affect the aesthetic quality of the water. Procedures to be followed if these limits are exceeded are included in the legally enforced rules and regulations. 23 II. ROUTINE MONITORING The only way to ensure water quality to the customer's tap is by maintaining sound infrastructure and properly operating the distribution of water throughout the system. The system's upkeep depends on accurate maintenance records and consistent routine monitoring. These records document that the system's drinking water is safe. Since all water used in the Tukwila system is supplied through Seattle, routine water quality testing is accomplished through Seattle Public Utilities and their associated lab. 10 to 12 samples are taken each month by SWD personnel from Tukwila system sampling stands. Tukwila has also prepared a Coliform Monitoring Plan in accordance with Department of Health regulations. Water samples are taken monthly by City staff for coliform testing as required by the Plan 24 CHAPTER SIX EMERGENCY RESPONSE PROGRAM I. OBJECTIVE The emergency response program is designed to restore service to the Utility's customers in the shortest time possible while minimizing damage and inconvenience caused by electrical, mechanical or structural failures in the water system. II. WATER SYSTEM PERSONNEL EMERGENCY CALL LIST During regular working hours the maintenance office can be contacted by calling 433-1860. The Public Works engineering office is at 433-0179 and the finance department is 433-1835. The following procedures are to be used to call out the maintenance department for emergency work at times other than regular working hours. Regular work hours are 7:00 A.M. to 3:30 P.M., Monday through Friday. 1. Call 369-5673 - If no answer see #2 2. Call Division 1 Superintendent 246-6459 - If no answer see #3. 3. Call Water Crew Chief 630-3247 or the crew chief of the affected utility. Check the most updated Standby/call out procedures list for more (A sample is provided in APPENDIX A). This list is available through the Public Works offices and through the Tukwila Police Department. III. VULNERABILITY ANALYSIS AND CONTINGENCY PLAIN The City has an emergency services operation plan. The basic plan is listed in APPENDIX B. A. Source - The City buys all of its water from the Seattle Public Utilities. Loss of this source means that Tukwila would be quickly out of water. A contingency would be opening up the interties between Kent, Highline or 25 B. AUTHORITY & APPLICATION Authority for requiring water use restrictions during emergency situations is granted to the Director of Public Works by City Ordinance No. 1592. These restrictions will apply to all Tukwila water customers and may include monetary penalties for repeat violations. C. PLAN COMPONENTS The plans for the Summer and Fall shortage scenarios are multi -staged, with the stages designed to be implemented as progressively more serious conditions develop. A description of each stage is listed in the Plan and parallels very closely the Seattle Public Utilities's Water Shortage Contingency Plan. D. WATER SHORTAGE PROCEDURES Tukwila staff will follow procedures as outlined below during a water shortage emergency: GENERAL: 1. Check answering machine for calls and reports. 2. Wear city shirt for identification. 3. Use city vehicle. 4. Meet with people whenever possible. 5. Be courteous and friendly. Try to be as helpful and informative as possible. 6. Give the water watcher hot line number (433-1868) for information. 7. Take pictures of misuse and notify users of violation. 8. Try not try to wake people. Hang notice on door if no one is home or if you think they might be sleeping. 9. Turn in list of violators that you have found to the Crew Chief. EARLY SHIFT, SPECIAL SHIFTS AND CALL OUTS 1. Check locations previously notified of water misuse. 27 28 CHAPTER SEVEN CROSS -CONNECTION CONTROL PLAN I. OBJECTIVE II. A cross -connection is any actual or potential link between drinking water and substances which are not part of the potable drinking supply. Contamination of the water system is possible through the action of backflow, typically caused by backsiphonage or backpressure. The potential for contamination of water lines at cross -connections requires conducting a program to protect the health of water consumers. This is to be done by systematically identifying and controlling actual or potential cross -connections. MUNICIPAL UTILITY'S PROGRAM The City of Tukwila follows the criteria for minimum standards, permits, record keeping, testing procedures, inspection and follow-up as shown in the Cross Connection Control Manual AWWA M14. III. RESPONSIBLE PERSON The Superintendent, Water Crew Chief and field personnel are trained and certified for the control of cross -connections. 29 CHAPTER EIGHT WATER CONSERVATION PLAN I. OBJECTIVE Tukwila is committed to meeting the guidelines for wholesale customers as outlined in the Seattle Public Utilities Supply Plan under Appendix III titled "Long Term Conservation Plan". In order to assure that an adequate and high-quality supply of water is available to meet future water needs, it is necessary to implement long-range plans, programs and facility development and rehabilitation projects in consultation with the existing wholesale supplier, the Seattle Public Utilities. In addition to participating in regional conservation programs, the Tukwila water utility provides information directly to its customers regarding the importance of water conservation. Specific measures given in the Tukwila Water Comprehensive Plan include public education, technical and administrative assistance, leak detection, metering policies, seasonal rates, and developing irrigation use for reclaimed wastewater from the Renton Treatment plant (See the 1991 Water Comprehensive Plan for specific details). II. ONGOING PROGRAMS Specific ongoing actions relating to water conservation in the City of Tukwila are: ♦ Higher Summer water rates for June through September. ♦ Reminding customers about conserving water. (TMC 14.04.180 prohibits water falling on street or sidewalk.) ♦ Water conservation tips printed on utility bills. ♦ Conservation posters/literature available at City Hall. ♦ Analysis of non -revenue water and leak detection. ♦ Analysis of consumptive trends with the flow telemetry. 30 ♦ Alerting customers as to abnormal meter readings. ♦ Assisting customers with plumbing questions on water saving devices. ♦ Requesting drought tolerant plantings and "rain smart" irrigation systems at permit application review. ♦ Commercial toilet retrofit in cooperation with SWD and large irrigation system audits. 31 SAMPLE PUBLIC WORKS DEPARTMENT STANDBY/CALL OUT .PROCEDURES APPENDIX A REVISED 3/94 The following procedures are to be used to call out the maintenance department for emergency work at times other than regular working hours.

The facilities responsibility is directed by the Building Maintenance Supervisor who reports directly to the Superintendent. The equipment responsibility is directed by the Lead Mechanic who also reports directly to the Superintendent. II. Emergency Response. The Public Works Department can be mobilized through established callout procedures and often is the first response department in situations involving natural disasters. In addition, all public works vehicles contain mobile communications capability via cellular phone and/or FM radio. Emergency callout numbers are posted in the Police Department along with an employee roster. III. Emergency Functions. The following paragraphs outline the primary and support (secondary) functions which can be provided by the Public Works Department during and after an emergency event. The functions are segregated according to the three Divisions of Public Works. A. Engineering: 1. Primary Functions. a. Damage Assessment/Control - The Engineering Division contains personnel who are intimately familiar with the infrastructure systems of the City and also have experience ANNEX - R Public Works Department PAGE TWO in the various engineering disciplines such as hydrology, geology, soils, and structures. In the event of a natural or manmade disaster, teams of engineers can be mobilized to field locations to provide damage reports and prioritization in terms of the likely -threats to public safety and property. In addition, these same teams can engineer field solutions to threatening situationsand supervise the implementation of remedial measures. b. Determination of Transportation/Evacuation Routes - The Engineering Division also has access to detailed aerial maps and road maps as well as the expertise and familiarity with City layout to devise primary transportation and evacuation routes during emergency events. c. Post -Disaster Reconstruction - As in the case of planning for future infrastructure improvements, the Engineering Division will assume the lead role in re-establishing critical services following an emergency event. 2. Secondary Functions. a. Notification/Warning - Engineering staff know the layout of the City and have vehicles equipped with communications to assist with local warning and notification efforts as needed. b. EOC Staff - If not needed in the field for primary functions, engineers and clerical staff can provide support services for the EOC operations. c. Traffic Control - Most Engineering personnel are trained in proper traffic control techniques and can assist in this function when primary functions are not required. B. Division I: 1. Primary Functions. a. Debris Removal - Division I has personnel trained in the operation of heavy equipment such as bulldozers, backhoes, trackhoes, ANNEX - R Public Works Department PAGE THREE front-end loaders, and graders. The Division has several pieces of their own equipment, including a twelve -yard dump truck. In addition, the Division frequently rents heavy equipment from local providers and maintains current contacts with such suppliers. Equipment and personnel are based at the Minkler Shops Facility within easy access of the primary EOC. b.

Although we have found the plan to be very thorough and well prepared, we ask that you please address the following comments before final approval. 1. The plan should contain both a service area map and a service area agreement signed in accordance with the Skyway Coordinated Water System Plan (CWSP). However, we understand that the Skyway Water Utility Coordinating Committee is currently updating the CWSP and has yet to finalize the service area boundaries and agreements therein. For final approval, the plan must contain a clear service area boundary map showing the area that the City intends to serve in accordance with the updated CWSP. If the green area on figure 1-5 is the formal service area, then please indicate it on the map. Copies of the signed service area agreement, once finalized, should be forwarded to the department. The water system relies upon the City of Seattle (SPU) to meet the Plan's recommended standby storage volumes. Has this issue been discussed with SPU and could it be a problem after 2012? 3. Conservation Plan The conservation plan must identify a percentage savings goal and include this target savings in the plan's demand projections. For instance, the per capita demand figure (78.2) in Table 2-12 remains constant through the year 2017. Per capita demand should decrease if the City's conservation program is effective. Projected Commercial and industrial savings should also be factored into the demand forecast. A new demand forecast which includes the target conservation savings can be added to the plan's current demand projections in a separate column. The Data described in Table 5-1 should be reported and included in this WSP. Is this data currently available? If not, when can the department expect to receive it? Page 6-4 indicates that a leak detection program will be implemented during 1998 yet the Capital Facility Plan presented in Table 6-3 does not provide for leak detection survey until 2001. Please clarify when these efforts will be made and how it will affect the projected conservation savings. 0 City of Tukwila Water Depatulent October 1, 1998 Page 2 4. Tukwila's Coliforrn Monitoring Plan should be referenced in the 0 & M section. 5. The Tukwila Developer Extension Standards indicate that new water mains will be installed at a niiniinum'aepth of at least 36 inches to the bottom of the pipe. The existing standards for the Skyway. CWSSA require a minimum of 30 inches of cover over the top of the pipe. Please reviewthe standards and make the necessary correction. 6. ..

In keeping with the approach of the SPU Water Supply Plan, SPU is reviewing all purveyor draft complans to assure more consistent planning and enable coordinated operation of Seattle's regional water system and purveyor's distribution systems. SPU comments and recommendations are intended to assist you in achieving timely approval of your plan. DEMAND FORECAST The SPU reviewer feels that this section of the plan is very well done. The overall forecast is consistent with Seattle's forecast of demand for Tukwila. The forecast methodology takes into account the fact that most of Tukwila's consumption is non- residential. However, the reviewer was concerned that non-residential demand is forecast by scaling up current non-residential consumption by the projected rate of population growth for King County as a whole (22% over 20 years). The idea appears to be that commercial activity in Tukwila is more likely to be related to regional rather than local population growth. This assumption could result in too low a forecast of non-residential demand given that employment in Tukwila is projected to grow 45% by 2020, twice as fast as King County population. But it's hard to say how big of a problem this is since the multiplier between employment and water consumption tends to be less than 1. Editorial comments: Page 2-11. According to both my calculations and Table 2-11, Tukwila population is expected to grow by about 95% over 20 years. However, the last sentence of the first full paragraph on the same page says, "Both FAZ areas had average increases in population of approximately 40 percent." Either this is an error or is meant to refer to the growth rate in each of two consecutive 10 years periods. If the latter, it is confusing and should be rephrased.

By early summer 1998, - it was clear that wholesale rates would change significantly in 1999 and 2000. For a number of reasons (including the clearing of purveyor balance accounts), a much higher percent of purveyor costs were allocated to "old water" and much less to "new water." As a result, old water rates for 1999 are 41% higher than in 1998 while the growth charge has been cut in half. The overall purveyor rate increase for 1999 is 13.8%. However, purveyors like Tukwila with little or no purchases of new water will see much larger increases in their bill - up to 40% in 1999, followed by a 16% increase in 2000. Purveyor water rates through 2000 are as follows: 1998 1999 2000 Old Water Rate Winter $0.31/ccf $0.44/ccf $0.51/ccf Summer $0.80/ccf $1.12/ccf $1.30/ccf Growth Charge $1.05/ccf $0.50/ccf $0.50/ccf WATER QUALITY See attached Water Quality Review CHECKLIST and proofed copy of the Water Quality section of your complan. SYSTEM ANALYSIS One element of the water system that we look for in our review is the discussion of how much storage is required and, in particular, whether the purveyor appears to rely on Seattle storage and transmission facilities in the calculations. The discussion on storage (p. 1-6) is relatively brief. It includes the following statement: "The City relies on Seattle's storage and supply abilities for peak demands and fire flows. Although Seattle has adequate facilities for supplying Tukwila's peak demands, this method of operation results in frequent demand charges by Seattle." The discussion on storage (p.3-18) observes that the Tukwila water system is deficient in standby storage and includes the following statement: "Because Tukwila is part of a consecutive water system, there is no requirement to construct more storage facilities for the City's water service area. However, these calculations can serve as a basis for future storage requirements should DOH determine that the Seattle systemis unreliable." It must be pointed out, as has been done with several other purveyor water system plans, that the purveyor needs to provide minimum storage for fire fighting and emergency standby uses without reliance on Seattle. In a major catastrophe, the supply from one or more of the transmission pipelines could be interrupted until repairs were made. The required storage volume is a matter for the State Department of Health and the purveyor to determine. The SPU reviewer had no other significant comments.

CONSULTING ENGINEERS February 4, 1999 Mr. Ernie Dunston, Purveyor Liaison Seattle Public Utilities Dexter Horton Building, 10th Floor 710 Second Avenue Seattle, Washington 98104 SUBJECT: TUKWILA WATER SYSTEM PLAN UPDATE, SPU COMMENTS CITY OF TUKWILA, KING COUNTY, WASHINGTON G&O #97794.00 Dear Mr. Dunston: We received, on January 11th, your comments regarding the City of Tukwila's Draft Water System Comprehensive Plan. We appreciate your input and thank you for the time your staff has spent reviewing the plan. The comments from you letter were incorporated into the plan as appropriate, and this letter is intended to describe how each of the comments was addressed in the final plan. Demand Forecast The sentence regarding population growth in each FAZ area has been rephrased to more clearly state that growth is projected to increase at a rate of 40% during each of the two ten-year periods in each FAZ area. Purveyor wholesale water rates have been revised according to the most recent numbers supplied in your letter. The City's forecasted revenues and expenditures have also been revised using this data, and rate impacts for Tukwila have been adjusted accordingly. Because wholesale water rates were only given through 2000, it was assumed that they would not change after that year through the six-year planning period. Water Quality The edits were incorporated into the water quality portion of the System Analysis chapter. Many of the comments from the Water Quality Checklist are addressed in the City's Operations & Manual which is included in the Appendices of the Plan. As suggested, a reference to the City's cross connection control program and operator certifications in their 0 & M manual was also inserted. A brief discussion of the Consumer Confidence Report was included in this section as well. System Analysis Storage issues that were raised in the SPU comment letter were further clarified in a conversation with Bob Schwartz of SPU. As is implied in the Plan, Tukwila relies on Seattle to supply all of its storage requirements under normal operating circumstances. 701 Dexter Avenue N., Suite 200 Seattle, Washington 98109 (206) 284-0860 Fax (206) 283-3206 Mr. Ernie Dunston February 4, 1999 Page 2 During an area -wide emergency or catastrophic failure of an SPU Pipeline, the City of Seattle may be unable to guarantee an emergency source of storage. For all practical purposes, however, SPU storage is available for Tukwila under nearly all conditions. The purveyor contract between Seattle and Tukwila also states that Seattle may levy a surcharge on wholesale water rates in order to recover any emergency expenditures. However, there is no contractual limitation on the amount of water which Tukwila can withdraw from the Seattle system. Conservation A discussion of Seattle's Smart water Technology and the Laundrywise program have been included in the Conservation section. As suggested, the relationship between sewer and water bills was also mentioned. Once again, we appreciate your comments on the Tulcwila Water System Comprehensive Plan and if you have any questions regarding the Plan or this letter, please feel free to contact the undersigned.
