Georgetown Wet Weather Treatment Station

Project description

The Georgetown Wet Weather Treatment Station, located at the corner of 4th Avenue and South Michigan Street in Seattle’s Georgetown neighborhood, can treat up to 70 million gallons of combined rain and wastewater a day that would otherwise discharge directly to the Duwamish River during heavy storms. Before the station was completed in 2022, heavy rains would fill up the area's sewer pipes, sending polluted runoff and sewage through a pipe into the river. 

King County will be offering tours and education programs starting in mid-2024. Stay tuned for more information. (To request tours of other King County treatment plants, contact the education team.)

Good news! The Georgetown Wet Weather Treatment Station is now operating, cleaning millions of gallons of polluted stormwater runoff that would have otherwise flowed directly into the Duwamish River and Puget Sound. Our teams are busy optimizing the station so it can do the best job possible protecting public health and the environment with excellent water quality.
