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.

What to expect during construction:

  • No interruption to wastewater service.
  • One-lane alternating traffic on Beach Drive SW, with steel plates in the road. Bicyclists should use extreme caution passing through the work area.
  • Lowman Beach Park playground, beach and sidewalks will remain open during construction.
  • Typical construction noise near work areas.
  • Street parking is restricted to construction during the posted hours. Please follow the parking sign instructions.

Coating pump station hatches around June 23 and June 24

Crews will install protective coating on pump station hatches next week. Installing the coatings is part of the final work at the pump station. Work will take place on Tuesday, June 23 or Wednesday, June 24. Park visitors may notice light paint smells from the coating while it dries.

Crews continue pipe repairs at the northeast corner of Lowman Beach Park and along Beach Drive SE.

Most of the park will remain open during construction. The road and park will be restored this fall and early winter after the pipe work is complete. Thank you for your understanding and patience while we complete this work.
