Power outage during windstorm leads to overflow at King County’s Richmond Beach Pump Station


About 130,000 gallons of wastewater spilled into Puget Sound from a King County pump station that was affected by a power outage during a Dec. 14 windstorm.


A powerful windstorm and power outage in Shoreline Dec. 14 led to a wastewater overflow into Puget Sound from King County’s Richmond Beach Pump Station.

Power at the pump station went out at approximately 7:12 p.m. on Friday, Dec. 14. A King County wastewater operator responding to the power outage determined an electrician was needed to reset the pump station breaker to resume backup power. 

Normal pump station operations resumed at 9:17 p.m. It is estimated about 130,000 gallons of wastewater overflowed into the Puget Sound.

King County reported the overflow to health and regulatory agencies and initiated beach monitoring, which has found no exceedances of water quality.   

The Richmond Beach Pump Station is located at 2740 NW 198th St., just south of Point Wells.
