Barton Street Pump Station upgrade project
June 3, 2015
Construction is nearly complete for the Barton Pump Station Upgrade Project. As crews finish final construction activities over the next month, King County will continue to notify the community and ferry commuters should any ferry lane closures or work requiring additional notification occur.
Over the past month, crews received artwork, poured concrete for driveway and sidewalks, continued painting, and started installing landscape irrigation.

Need for project
King County protects public health and the environment by conveying and treating the region's wastewater. The Barton Street Pump Station is 50 years old. King County must upgrade the facility 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 at 9005 Fauntleroy Way, SW. The pump station pumps wastewater to the Murray Avenue Pump Station which then pump flows to the county's regional treatment plant at West Point in Seattle.

The pump station was first constructed in 1958. The following necessary improvements will be made:
- Replace outdated electrical equipment, pumps, and associated equipment. The new pumps will increase capacity from 22 million gallons per day (mgd) to 33 mgd
- Upgrade heating, ventilation and air conditioning
- Construct a new underground vault to house a new backup generator system and a new odor control system
- Construct a new underground valve room and install new valves for the two 24-inch force mains that were installed as part of a 2006 emergency repair project
These upgrades will require the demolition of the existing below ground pump station and the construction of a temporary pumping system that will be removed once the new system is operational.
Being a good neighbor
King County is committed to being a good neighbor and will work directly with the community throughout the project to minimize construction impacts whenever possible. Residents can expect:
- Advance notice of construction activities via mail, email, phone, and project fliers
- One-on-one problem solving with residents directly impacted by construction activities
- Project website and construction updates
- 24-hour construction hotline
