We reported last month about the King County Wastewater Treatment District’s new plans for West Seattle and South Seattle, including a 7-million-gallon-plus overflow storage tank off West Marginal Way SW. It’s meant to reduce overflows of combined sewage and stormwater into the Duwamish River. If you have questions about that or other parts of the “Mouth of the Duwamish” project, the drop-in session mentioned last month is coming up – here’s the reminder we received:

King County has proposed a solution to control overflows from five combined sewer overflow (CSO) outfalls at the mouth of the Duwamish River. The proposed solution to improve water quality in the Duwamish River and Elliott Bay includes a new wet weather treatment station in SODO and a new storage tank in West Seattle (Industrial District West). It also includes a new outfall for cleaned water, supporting facilities, and new pipes to connect flows along the way.

Now that we have a proposed solution, we will prepare an engineering report for review by the Washington State Department of Ecology. We will also start the design phase and environmental review.
