Why we did this project

King County relined a section of damaged sewer pipe and installed new valves at the Murray Pump Station. The repairs ensure reliable wastewater service continues for West Seattle residents. It also helps protect public health and Puget Sound.

The Murray Pump Station has two pressurized sewer pipelines, also known as force mains. These pipelines run parallel under Beach Drive Southwest and help move sewage to West Point Treatment Plant. After treatment, the water will be safely returned 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 repaired the remaining 350 feet of damaged pipe and installed new valves to improve the system.
