53rd Avenue Pump Station upgrade

Completed – Winter 2010

From spring 2008 to winter 2010 King County rebuilt the ageing 53rd Avenue Pump Station and added new odor control equipment, upgrades to the facility’s electrical and mechanical systems, and doubling the size of the below-ground facilities. This facility will provide safe, reliable service for the next 50 years in the Alki area of Seattle.

The renovated pump station can pump 17 million gallons of wastewater per day to the county's regional treatment plant at West Point in Seattle.

Major changes to pump station

  • Expanded pump station vault to the west 70 feet
  • New pumps and associated mechanical equipment
  • New odor control equipment
  • Standby generator
  • All new electrical and control system

The pump station is located at 53rd Avenue Southwest and Alki Boulevard.
