Murray Force Main Rehabilitation

The Murray Force Main Rehabilitation project will rebuild a section of a pressurized sewer pipe called a force main to maintain reliable service to West Seattle residents living near Lowman Beach Park.

Project description

King County is rebuilding a damaged sewer pipe to maintain reliable sewer service for West Seattle residents near Lowman Beach Park and protect public health and Puget Sound.

The Murray Pump Station has two pressurized sewer pipes, also known as force mains. These pipes run parallel under Beach Drive Southwest and help move sewage to West Point Treatment Plant, where it is cleaned and safely discharged into Puget Sound. In March 2022, one of the pressurized pipes broke due to severe corrosion. King County repaired about 800 feet of the damaged pipe at that time. This project will repair the remaining 350 feet of damaged pipe and install two air valves to help reduce pipe corrosion in the repaired pipe.

This work needs to occur during the dry season when wastewater flows are lower. Road and park restoration will occur in fall 2026 after the pipe is rebuilt.
