BACKGROUND The DOE recently contacted staff about potential available funding for project or other needs associated with water quality and /or meeting the requirements of the City's NPDES permit. The DOE has excess grant funding that can be used for other projects and are asking jurisdictions for projects which need additional funding. Staff looked at current project and equipment needs and discussed these with the DOE. It was determined that the purchase of a Video Inspection Vehicle or TV Van and associated equipment, would meet their intent of addressing an NPDES need and they encouraged the City to request a portion of the acquisition costs be covered by the grant funds. ANALYSIS The City's 2013 -2014 Biennial Budget has funds programmed in the 501 fund to acquire a replacement TV Van and equipment in 2013. Staff is currently negotiating with a vendor for the desired vehicle through the Houston - Galveston Area Council. FISCAL IMPACT A total of $180,000 has been budgeted for the purchase of the Video Inspection Vehicle and total cost may be slightly higher than the budget. It is anticipated that up to $30,000 is available in DOE grant funding. No specific matching requirements have been identified to date; however, with the cost of the vehicle, we would more than qualify for any match requirement. Any grant funds received would be used to offset the overall cost of the scheduled vehicle purchase. RECOMMENDATION Committee approval for submittal of the grant request to the DOE for the scheduled purchase of a Video Inspection Vehicle.

Page 331 2 TO: City of Tukwila Jim Haggerton, Mayor INFORMATIONAL MEMORANDUM Mayor Haggerton Utilities Committee FROM: Bob Giberson, Public Works Director BY: Mike Cusick, Senior Engineer DATE: February 15, 2013 SUBJECT: Sewer Comprehensive Plan Project No. 91040101 Sanitary Sewer Comprehensive Plan Update for Capital Improvement Projects ISSUE New capital projects for sanitary sewer based on the Comprehensive Sewer Plan. BACKGROUND In 2010 the City contracted with Carollo Engineers to update the Sanitary Sewer Comprehensive Plan. DISCUSSION Carollo Engineers has recommended that the following projects be added to the Capital Improvement Program (CIP): 1) The Comprehensive Plan recommends that future Lift Station No. 13 be installed in the City owned right -of -way, just east of Schneider Homes located at 6510 Southcenter Blvd. Sewer Lift Station No. 13 will take sewage flows from Old Tukwila Hill, which currently runs under 1 -405 to Lift Station No. 12, located just south of the Post Office to Southcenter Blvd., then to the existing Metro sewer line, which crosses under 1 -5 near the 15200 block of Macadam Rd S. The scope of work also includes an upgrade to the gravity sewer line on Southcenter Blvd. (Pages 121 & 122 of the 2013 -2018 CIP). 2) Carollo Engineers is also recommending that the sanitary sewer system be modeled to ensure that it is not over capacity in the next Sewer System update, scheduled for 2017. In Chapter 6 of the 2005 Sewer Comprehensive Plan, sewer pipes in the CBD were flowing at lower than 60% capacity. Future CIP Projects: A. Replacement of Sewer Lift Stations No. 5 and No. 6 in the year 2025. These two sewer lift stations were installed in 1975 for Fort Dent Park and Starfire and will reach the end of their life cycle in 2025. B. Replacement of pumps in Sewer Lift Stations No. 8 and No. 10 in the year 2027. These two sewer lift stations were installed in 2007 in Allentown and Foster Point neighborhoods. C. Replacement of pumps in Sewer Lift Station No. 11 in the year 2032. This sewer lift station was installed in 2012 for Tukwila South. D. Annual replacement of pipes. The consultant is recommending that the City replace aging sewer pipes near the end of their life cycle. This is currently underway with the CBD Sanitary Sewer Rehabilitation Project.

Cost estimates provided by City. 7.3.1.1 Replace and Expand Lift Station 2 (L -1) It is projected that Lift Station 2 will experience a large increase in flow as this station will convey flows from the new Drainage Basin 14 (via Lift Station 11) to the King County sewer system. The City has observed no growth recently for the new area, and thus does not anticipate a large increase in flows within the near -term timeframe. Lift Station 2 has an on -site generator that has reached the end of its useful life and will need to be replaced within the short -term timeframe. For the purposes of this CIP, it is anticipated that Lift Station 2 will have to be replaced and expanded within the long -term timeframe. 7.3.1.2 Replace and Expand Lift Station 3 (L -2) Flows to List Station 3 are projected to exceed the lift station capacity by the year 2030. The City has observed minimal growth recently in the flow to Lift Station 3 and does not anticipate that the station's capacity will be exceeded in the near -term. Lift Station 3 has a wet pit/dry pit type of configuration and the lift station structure will reach its useful life in year 2022. Carollo recommends that the City monitor the Lift Station 3 flows and replace this station with a submersible lift station when the capacity is exceeded. For the purposes of this CIP, it is anticipated that Lift Station 3 will need to be replaced and expanded within the long -term timeframe. 7.3.1.3 Replace Lift Station 4 (L -3) Based on the hydraulic capacity analysis, Lift Station 4 has adequate firm capacity for the year 2030 projected flows. However, the condition of the lift station is fair and may need to be CAROLLO ENGINEERS 7 -4 pw. / /Carollo/ Documents /Clienh!WA /Tukwila /8472A00/Deliverabes /Chapter 7 /Ch07.docx February 2013 4 CITY OF TUKWILA CAPITAL IMPROVEMENTS PLAN replaced. Due to these condition concerns, it is recommended that this lift station be replaced with a submersible station within the long -term timeframe. 7.3.1.4 Replace Lift Station 5 (L -4) Lift Station 5 has adequate capacity for the predicted year 2030 flows. However, based a design life of 20 years, the pumps will reach the end of their useful life in year 2022. In addition, this station was built in 1975 with wet pit/dry pit configuration and the structure is anticipated to reach the end of its useful life by the year 2025. The overall condition of this lift station was rated as "fair" and thus it is recommended that this lift station be replaced within the long -term timeframe with a submersible type lift station. 7.3.1.5 Replace Lift Station 6 (L -5) Lift Station 6 has adequate capacity for the predicted year 2030 flows. However, based a design life of 20 years the pumps will reach the end of their useful life in year 2019. In addition, this station was built in 1975 with wet pit/dry pit configuration and the structure is anticipated to reach the end of its useful life by the year 2025. The overall condition of this lift station was rated as "fair" and thus it is recommended that this lift station be replaced within the long -term timeframe with a submersible type lift station. 7.3.1.6 Replacement of Pumps at Lift Station 8 (L -6) Lift Station 8 is a submersible stations built in 2007 and it is anticipated that the pumps will reach the end of their useful life in the year 2027. Based on the capacity analysis, the station has sufficient capacity to meet year 2030 predicted flows. Carollo recommends performing a pump draw down test to confirm the pumps actual capacity and replacing the pumps when the tests indicate that pump station firm capacity is less than is required. For this CIP, new pumps at Lift Station 8 were assumed for the long -term timeframe. 7.3.1.7 Abandon Lift Station 9 (L -7) Lift Station 9 has pumps that have already reached the end of their useful life, based on an assumed 20 -year design life. In addition, the station has a wet pit/dry pit configuration and the structure is anticipated to reach the end of its useful life in the year 2030. The City wishes to eliminate this lift station and connect to the nearest King County sewer in Interurban Ave South. For this CIP, costs for demolition of entire station and connecting to the King County trunk line are included in the long -term timeframe. 7.3.1.8 Replacement of Pumps at Lift Station 10 (L -8) Lift Station 10 is a submersible station, built in 2007 and it is anticipated that the pumps will reach the end of their useful life in the year 2027. Based on the capacity analysis, the station has sufficient capacity to meet year 2030 predicted flows. Carollo recommends performing a pump draw down test to confirm the pumps actual capacity and replacing the pumps when the tests indicate that pump station firm capacity is less than is required. For this CIP, new pumps at Lift Stations 10 were assumed for the long -term timeframe. CAROLLO ENGINEERS 7 -5 pwJ/ CarolloiDocuments /Client/WA/Tukwi!ai8472A00 /Deliverables /Chapter 7 /Ch07.docx February 2013 5 CITY OF TUKWILA CAPITAL IMPROVEMENTS PLAN 7.3.1.9 Replace Lift Station 12 (L -9) Lift Station 12 conveys flows from Drainage Basins 4 and 8 to the King County trunk. Similar to Lift Stations 5, 6, and 9, Lift Station 12 also has sufficient capacity to convey the predicted year 2030 flows. The station was originally built in 1972 (wet pit/dry pit style) and pumps were replaced in 2003. It is anticipated that both the pumps and structure reach their useful life by year 2023. The City is currently considering alternatives to serve Drainage Basin 4. Depending on the City's decision, flows to Lift Station 12 may be significantly different than predicted. Therefore, it is recommended that the City first monitor flows at the lift station and then replace it with submersible style station when either the flow to the station exceeds the firm capacity of the pumps or when the pumps and structure reach the end of their useful life. For this CIP, a new Lift Station 12 was assumed for the long -term timeframe. Due to the size of this project, it is anticipated that design will last one year and construction will last two years. 7.3.1.10 Replacement of Lift Station Generators (L -10) As the generators at the lift stations age, they will need to be replaced. To fund this replacement, the City is planning on establishing a generator replacement fund with an annual contribution rate of $10,000. 7.3.2 Pipeline Projects The City's sewer system will require several improvements to adequately provide service through the planning period. Several pipes were identified as having reached the end of their useful life or deficient due to sags. The following section presents a summary and estimated project costs to replace or repair the deficiencies in the system. Additionally, the City currently has a rigorous infiltration and inflow (Ill) reduction program and continued funding of this program is recommended through the planning period. Figure 7.2 presents the location of the pipelines CIP projects. A summary of pipeline project costs is presented in Table 7.3. 7.3.2.1 Annual Pipeline Repair Program (P -1) The City has several sections of the conveyance system that are estimated to have reached the end of their useful life. It is estimated that the annual pipeline repair program for the City's sewers would cost approximately $1,490,000 per year. The City will evaluate which projects to include in this program on a yearly basis.
