Lake Hills and NW Lake Sammamish sewer upgrade
August 7, 2018
Project design details coming into focus
King County continues to make progress on the final design for the Lake Hills/NW Lake Sammamish Sewer Upgrade Project. We’ve completed the basics of where the sewer pipe will go, how we’ll keep flows moving and the methods we will use to build the new pipe. We've also been working closely with the City of Redmond to identify the best way to meet future water supply needs for Marymoor Park. As a result, King County is anticipating that we will not need to install a recycled water line as part of this project.
Now we are focusing on items like environmental review, restoration plans, permit applications and what order we will build each part of the pipe. Check out the latest project mailer to learn more about the latest design progress and the environmental review process .

The Lake Hills and NW Lake Sammamish sewer pipe has been serving Redmond and Bellevue for 50 years. The water you use travels down your drain to City sewer systems. The City’s pipes send wastewater to King County’s sewer system where it is carried to the Brightwater Treatment Facility in Woodinville for treatment.
King County is working on a project to upgrade 4.5 miles of this sewer pipe. King County will build the new pipe in trails, roads and parks in Redmond. This project is necessary to meet the needs of your growing community. Construction is expected to begin in 2020 and may impact your daily routine. When complete, the new pipe will provide sewer service for 50 years or more.
