DATE: February 15, 2013
SUBJECT: Video Inspection Vehicle
Project No. 81341202
Department of Ecology Grant Application
ISSUE
Approve a grant funding request to the Washington State Department of Ecology (DOE) for the
purchase of the Video Inspection Vehicle and Equipment.
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.

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.

Notes:
1. 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

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.

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.

CITY OF TUKWILA CAPITAL PROJECT SUMMARY
2013 to 2018
PROJECT: Future Sewer Lift Station No. 13 Project No. 99740205
DESCRIPTION: Due to utility conflicts with existing utilities, a new sewer lift station will be required near 65th Ave S and
Southcenter Blvd. A gravity sewer main is not possible under 1 -405.
JUSTIFICATION: Existing line is undersized and has a severe sag. Increased development on the North Hill exacerbates
the deficiency.
STATUS: Design will be coordinated with WSDOT and Seattle Public Utilities.
MAINT. IMPACT: Less flushing maintenance to clear debris from sag and from the improved HOV manhole alignment.
COMMENT:
Other alternatives are being reviewed due to WSDOT requirements. Formerly known as Gravity Sewer
