King County is committed to the environment, and construction projects are no exception. Learn more about the County’s commitment to trees in this fact sheet about the plan for trees along the future sewer route. Many plants and trees have grown up around the sewer pipe since it was installed 50 years ago. While the design team works to protect sensitive environments and trees, impacts can’t always be avoided. Our team is working with Tribes, local jurisdictions, and permitting agencies to protect the existing trees, minimize removals, and develop restoration plans.
The goal is a future tree canopy that is equal to or better than what exists today. Read more in The Plan for Trees fact sheet .

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.
