The Barton Pump Station Upgrade project is proceeding ahead of schedule. Crews anticipate project completion in late fall 2014, several months ahead of the planned spring 2015 completion date. The pump station, built in 1958, is an underground wastewater facility that moves sewage from parts of West Seattle north toward the West Point Treatment Plant in Magnolia. When complete, the pump station will house new and upgraded equipment, including an upgraded odor control system and new standby generator.

Progress Update and Upcoming Activities
The concrete structures – walls, floors, and roofs – of the pump station, odor control room, and pipe housing area (utilidor) are complete. The coming months will focus on installation of pipes, pumps, and other equipment necessary to safely pump wastewater through the station. By summer crews expect to be
working on site restoration, including retaining walls, landscaping and irrigation.

What to expect
 Underground work through the spring
 Truck traffic in and out of the site, with
flaggers to move vehicles around and
through the site
 Heavy equipment on site
 Work hours 7 a.m. to 5:30 p.m. Monday

Although crews anticipate a 2014 project completion date, unexpected circumstances could cause unanticipated delays. King County will notify the community and ferry commuters of any updates to the schedule and any time a new activity impacts neighbors or commuters.
