About the Project
Phase 2 of King County’s Murray Force Main Rehabilitation project starts on May 1. The project ensures reliable wastewater service for West Seattle residents. Crews will line a section of a pressurized sewer pipe called a “force main.” We will also replace the valves at Murray Pump Station. This work must take place during the dry season to avoid service disruptions. Road and park restoration will occur this fall and early winter after work is complete.
Thank you for your patience while we work on this project.
 Note: Construction area shown on the map is approximate. The project work zone begins from Lowman Beach Park on the southbound side of Beach Drive SW. It extends about 0.2 miles north from the park.
