Barton Street Pump Station upgrade

Facility operations 

Completed summer 2015

King County upgraded the aging Barton Street Pump Station to accommodate West Seattle’s growing population and ensure its safe and reliable operation for the next 50 years.

The pump station is an underground facility located next to the Fauntleroy ferry landing in West Seattle. The pump station pumps wastewater to the Murray Avenue Pump Station which then sends flows to the county’s regional treatment plant at West Point in Seattle.

Major changes to pump station

The pump station was first constructed in 1958. The following improvements were made:

  • Replaced outdated electrical equipment, pumps, and associated equipment.
  • Increased capacity from 22 million gallons per day (mgd) to 33 mgd
  • Upgraded heating, ventilation and air conditioning
  • Constructed a new underground vault to house a new backup generator system and a new odor control system
  • Constructed a new underground valve room and installed new valves for the two 24-inch force mains that were installed as part of a 2006 emergency repair project

24-Hour Emergency and odor reporting: contact West Point Treatment Plant at 206-263-3801.

Sheet Pile Driving Video
Learn how King County Wastewater Treatment Division creates safe underground work environments using a technique known as sheet pile driving. During the winter and spring of 2013, King County used a vibratory hammer to install sheet piles, a technique which works well in tight spaces with minimal impacts on nearby neighbors and the environment.
