West Seattle Pump Station maintenance begins at Lowman Beach Park, Sept. 7


Three-week project to pose temporary impacts to park users, neighbors


A sewer maintenance project that will help protect the inside of the Murray Avenue Pump Station from the corrosive effects of untreated wastewater is scheduled to begin Sept. 7.

Crews with King County’s clean-water utility will apply a protective paint to recoat the concrete walls of the station’s wet well, which is the structure that receives untreated wastewater. Work is dependent on dry weather and it’s estimated the project will take about three weeks to complete.

The pump station is located at 7015 Beach Drive SW in Seattle’s Lowman Beach Park. King County scheduled the project to begin following the Labor Day weekend and the start of a new school year for local students.

Project hours are Monday through Friday from 7 a.m. to 3:30 p.m. to enable the public to enjoy fall evenings and weekends in the park. The work area will be fenced off to protect public safety.

For the duration of the project, neighbors and park users should expect temporary impacts including construction noise, dust, odor, and limited parking on Beach Drive Southwest while crews are present.

People with questions or concerns can call the project hotline at 206-205-9196. Additional information about the project is also available online at

During the rainy season, the Murray pump station pushes an average of 5.1 million gallons of wastewater through a 13,000-foot pipeline to the 63rd Avenue Pump Station near Alki. The wastewater is eventually treated at the West Point Treatment Plant in Magnolia.

People enjoy clean water and a healthy environment because of King County's wastewater treatment program. The county’s Wastewater Treatment Division protects public health and water quality by serving 17 cities, 17 local sewer districts and more than 1.5 million residents in King, Snohomish and Pierce counties. Formerly called Metro, the regional clean-water agency now operated by King County has been preventing water pollution for nearly 50 years.
