Lakeland Hills Pump Station replacement

The Lakeland Hills Pump Station Replacement Project will replace the aging Lakeland Hills Pump Station and build a new facility in Auburn to upgrade sewer services in south King County.

Project description

King County owns and operates the Lakeland Hills Pump Station. King County will replace the aging Lakeland Hills Pump Station and build a new facility in Auburn to upgrade sewer services in south King County. The Lakeland Hills Pump Station is an important part of King County’s connected systems of pipes and pumps. The pump station moves sewage from homes, schools, and businesses in the Auburn area to South Treatment Plant in Renton to be treated, eventually sending it off safely into the Puget Sound. Replacing the pump station will prevent sewage overflows and help serve the growing population of Auburn for many years.

Project update

November 2024

Lakeland Hills Pump Station alternative site evaluation continues

King County is moving forward with plans to rebuild the Lakeland Hills Pump Station, boosting its capacity and keeping sewage flowing safely to the treatment plant. The project team continues to evaluate the alternative sites and we will share more updates in January.

We anticipate announcing the final site selection later in 2025. This would not be possible without the input from the community, which continues to guide our decisions every step of the way.

The elevator replacement project will begin November 4, 2024. Construction is expected to complete by December 2024. The backup generator project began in April 2023 and is completed as of August 2024.
