The strong windstorm overnight knocked out power and led to overflows at four of King County’s pump stations, sending wastewater into Puget Sound and Lake Washington, according to the county’s Wastewater Treatment Division.
An overflow at the Murray Pump Station, 7015 Beach Drive S.W. in West Seattle, began at 9:40 p.m. Saturday and lasted about 80 minutes.
Another overflow, this one at the Richmond Beach Pump Station, 2740 N.W. 198th St. in Shoreline, lasted for nine minutes.
An overflow into Lake Washington from the Kirkland Pump Station, Third Street and Park Lane, began at 9 p.m. and lasted about 35 minutes. Another overflow into Lake Washington occurred at the Sweyolocken Pump Station, 3100 Bellevue Way S.E.
In all four cases, crews used backup generators to restore power to the pump stations.
The county will notify health and regulatory agencies, sample water quality and post affected areas as closed to protect public health, according to the Wastewater Treatment Division.
