Thank you for stopping by our booth at the Bike Everywhere Day Event on May 20! We expect to be out along the Sammamish River Trail periodically to share information with trail users as we ramp up for start of construction in 2024. You might also see our project signage located in areas along the trail this summer season!
Construction is expected to begin in 2024. For the latest project information, check out the recording of the fall 2021 virtual neighborhood meeting.

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 2024 and may impact your daily routine. When complete, the new pipe will provide sewer service for 50 years or more.
