Story

King County sewer utility crews quickly stopped an overflow at the Murray Pump Station that was caused by an early-morning power failure in West Seattle.

The overflow lasted about 3-5 minutes, spilling an estimated 19,000 gallons of wastewater into Puget Sound near Lowman Beach Park.

Crews engaged a mobile generator currently staged at the site and quickly restored normal operation.

King County notified health and regulatory agencies about the overflow, took water quality samples, and posted signs warning people to avoid contact with the water.

King County is currently investing $26 million to upgrade Murray Pump Station as part of a long-term project to control overflows of stormwater and sewage that occur during heavy rains. Improvements include the installation a permanent back-up electrical system to provide power during outages and other emergencies.

The pump station has been in service since 1957.
