Project description

May 2016 project newsletter

The Georgetown Wet Weather Treatment Station has completed initial design work. The equipment, layout, and building materials have been decided, and now the project team is working on more detailed engineering drawings, and finer details about the site such as lighting, fencing, and plant selection. Georgetown neighbors and the community Design Advisory Group provided important input into the station’s look and feel. See examples of how the community influenced the design in the newsletter  and on the facility design page.

The Georgetown Wet Weather Treatment Station Project includes the construction of a combined sewer overflow (CSO) wet-weather treatment station between the Brandon Street and South Michigan Street Regulator Stations, related pipes  and a new outfall structure to release the treated water into the Duwamish River. When constructed, the station can treat up to 70 million gallons of combined rain and wastewater a day that would otherwise have discharged directly to the Duwamish without treatment during storm events.
