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
