Project update

September 18, 2020

Construction delayed until at least 2022

Construction for the Lake Hills/NW Lake Sammamish Sewer Upgrade Project is no longer expected to begin in 2021.

To complete the sewer upgrade, King County must get permits from the City of Redmond, City of Bellevue, and several state and federal agencies. It is important to take the time to get all necessary permits to install the new pipe in the safest way possible, limit impacts, and maximize improvements for people and the environment. While the project’s design continues, we are experiencing slowdowns in acquiring all the permits that are necessary to complete this work.

Construction will not begin until 2022 at the earliest. We expect to have a better estimate of when we will start construction by spring 2021. Thank you for your continued patience.

Project description

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 2022 and may impact your daily routine. When complete, the new pipe will provide sewer service for 50 years or more.
