West Point Treatment Plant
Increased construction traffic to West Point on March 23, March 30, and April 6 from 3 a.m. to 4 p.m.
Discovery Park and the Magnolia community will see increased cement truck traffic as crews pour concrete for the West Point Treatment Plant’s new battery storage building. From 3 a.m. to 4 p.m. on three consecutive Thursdays – March 23, March 30, and April 6 – approximately 80 cement trucks will travel through the Magnolia community to and from West Point in Discovery Park. King County continues working hard to improve the West Point Treatment Plant’s power reliability and protect Puget Sound.
Residents and park visitors can expect increased truck traffic and associated noise as vehicles travel through the area. There will be no road or park closures associated with these activities. This work is part of the Power Quality Improvement project.
West Point, located next to Discovery Park in Seattle, is part of King County’s regional wastewater treatment system.
West Point treats wastewater from homes and businesses in Seattle, Shoreline, north Lake Washington, north King County and parts of south Snohomish County. Seattle’s combined stormwater/wastewater sewer system also flows into West Point.
Approximately 90 million gallons a day of wastewater is treated at this facility during the dry months. During the rain/storm season, West Point provides secondary treatment for flows up to 300 million gallons a day (mgd) and provides primary treatment and disinfection for flows exceeding 300 mgd and up to 440 mgd.
