Project update - June 7, 2019

King County’s contractor is continuing to investigate and repair the new force main pipe along 164th Pl SE, SE 35th Pl and near the Heathfield Pump Station. Beginning as early as Monday June 17, crews will need to reopen the pit in the road near the intersection of 164th Pl SE and SE 35th Pl. This will allow them to test the pipe and make repairs. During this work, 164th Pl SE will be closed to through traffic in both directions, as it was during construction. We expect the closure to be in place around the clock for approximately six weeks. Depending on what the contractor finds in their continued investigation, they may need to extend the closure if more repairs are necessary.

Ongoing road and travel lane impacts are listed above.

Project description

The Sunset and Heathfield Pump Stations and related sewer pipes send sewage from Sammamish, Issaquah, and Bellevue to be cleaned at King County’s treatment plant in Renton. This sewer system has provided reliable service for around 50 years and is reaching its limit.

This project will upgrade both pump stations and the connected force main pipe. The project will also upgrade the Eastgate Trunk structure near I-90. The Eastgate Trunk connects the force main pipe to a larger pipe, carrying flows to be treated at the South Treatment Plant in Renton. The improved system will help serve the growing population for many years.

Read our December 2016 newsletter for more information about how community feedback influenced final design and for details about upgrades to the pump stations
