The Georgetown Wet Weather Treatment Station project teams sends a heartfelt thank you to the Design Advisory Group (DAG) members for their thoughtful, insightful participation in seven meetings over the past two years. The DAG’s design guidelines provided a guiding light for the architecture and landscaping of the project.

The DAG met for the final time at the South Seattle College Georgetown Campus on Wednesday, October 26. Topics included a presentation on design developments between the 30% and 60% design milestones, discussion of upcoming construction, and discussion of next steps for the project. View the presentation and meeting summary . Visit the public involvement page for past meetings.

Project description

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.
