Project update - February 21, 2019

Postponed until Saturday, Feb. 23, 7 a.m.: thirty (30) minute rolling road closure

On Saturday Feb. 23, crews will be moving a generator from Vasa Park to the Heathfield Pump Station via West Lake Sammamish Parkway SE, SE 34th St, and 164th Pl SE. The vehicle carrying the generator will move very slowly and will require a 30-minute rolling road closure. Once the generator reaches the Heathfield Pump Station, crews will prevent traffic from entering or exiting 163rd Ave SE for approximately 30 minutes.

This work is weather dependent; the duration, route, date and times are subject to change.

Saturday work expected through Feb. 23

King County’s contractor is working as quickly as possible to complete pipe installation in the project area. In order to expedite the process, and install remaining pipe as quickly and safely as possible, King County’s contractor plans to work on Saturdays through Feb. 23, from 7 a.m. to 6 p.m. Please note that hours may vary

The contractor plans to focus their Saturday work on key locations with remaining work, including, but not limited to, 164th Pl SE, near the Heathfield Pump Station.

Construction Progress Update

The project is still on schedule to be completed at the end of 2020. The pipe installation work, originally projected to be done at the end of 2018, will continue through late spring 2019. Read more about the schedule, work at specific locations, pipe installed and pipe left to install in the project update .

Work completed as of mid-January:

  • Replaced more than a mile of old pipe that was at the end of its service life – about 90% of the pipe to be replaced by this project
  • Completed the two most difficult pipe installations under West Lake Sammamish Parkway and Vasa Creek
  • Restored two of the five pits dug to install the pipe. The remaining pits are needed to finish installing the last 400 feet of pipe.

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.
