Heavy rains cause overflow into Lake Washington from Medina Pump Station

King County Wastewater Treatment Division’s Medina Pump Station experienced an overflow as a result of heavy rains in the service area.



King County reported a sewer overflow Friday afternoon at the Medina Pump Station as a result of heavy rainfall that exceeded the station’s capacity.

The pump station, located at NE 8th Street and 81st Avenue Northeast, is fully operational. It was designed with an emergency outfall to protect public health by directing overflows into Lake Washington instead of homes, streets, and businesses.

The overflow occurred from about 1 to 2:30 p.m.

King County’s Wastewater Treatment Division has notified health and regulatory agencies, will test water quality, and has posted signs at Medina Park Beach warning people to avoid contact with the water over the next several days as a precaution to protect public health.

The Wastewater Treatment Division protects public health and enhances the environment by collecting and treating wastewater while recycling valuable resources for the Puget Sound region. The division provides wastewater treatment services to 17 cities, 17 local sewer districts and more than 1.8 million residents across a 420-square-mile area in King, Snohomish and Pierce counties.
