Sewer Lift Station #2 Bid Award/Info Memo Bid Award McClure and Sons, Inc.docx 1 CITY OF TUKWILA CAPITAL PROJECT SUMMARY 2021 to 2026 PROJECT: CBD Sanitary Sewer Rehabilitation Project No. 91140203 The asbestos concrete pipe in the CBD (commercial business district) is approximately 45 years old and DESCRIPTION: becoming soft. Slip lining the pipe will reinforce the strength with little impact to roadways and minimal excavation.

We have had four major pipe failures on Andover Park West and Andover Park East. STATUS: In 2014 and 2015, over 10,500 feet of asbestos sanitary sewer pipe were relined. In 2020 through 2024, 15,000 feet of asbestos sewer is scheduled to be relined. MAINT. IMPACT: Reduced maintenance and repair costs. COMMENT: A Public Works Trust Fund loan was successfully obtained in 2012 for $750k.
