On June 16, 2016, Charles Blanc and Tristan Surtees of Sans Façon, the art master planners for King County’s Combined Sewer Overflow system in Seattle, presented their vision for the system-wide art master plan. The CSO Art Master Plan lays the foundation for 4Culture to commission artwork at the intersection of water, infrastructure, society and the environment.
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.
Why does King County need to do this project?
This project is part of a larger Combined Sewer Overflow (CSO) Control Plan Amendment that will reduce combined sewer overflows into local water bodies and protect public health and the environment. In this plan, there are 14 current or approved projects left to complete to reduce overflows that occur in the regional wastewater system. Duwamish projects, including the Georgetown Wet Weather Treatment Station, were prioritized based on what King County heard from the community.
This facility greatly reduces untreated wastewater and stormwater from entering the Duwamish.
The project timeline is as follows:
How King County works with the community
This project will protect the investments being made to clean up the Duwamish River and it will continue creating a better, cleaner river for South Park, Georgetown and the region to enjoy.
King County works with the community to provide project information and identify potential impacts.

Building a sustainable future
King County builds and operates facilities that benefit our communities, environment and economy.
King County is using a third-party verification program called Envision to track its sustainability efforts on the Georgetown project. We consider all of the following to design this facility:
