The Vine Street Basin Combined Sewer Overflows Control Project to keep Belltown wastewater out of Elliott Bay Open House.
Wednesday, February 6th from 5:30 – 7:30 PM at KPG Offices located at 3131 Elliott Ave #400 in Belltown – click here for Virtual Open House through February 13th.
Sewer pipes in Seattle carry sewage (wastewater) away from homes and buildings for treatment at King County’s treatment plants before discharging into Puget Sound. In some neighborhoods, like Belltown (Vine Basin), the same sewer pipes also carry untreated rain water (storm water) from roofs, drains and streets. During heavy rains, if the amount of sewage and storm water exceeds the sewer system capacity, the excess flows overflow into nearby water bodies through an outfall pipe. These overflows can harm fish, wildlife and swimmers. This is called a combined sewer overflow (CSO).
The Washington State Department of Ecology (Ecology) requires SPU to limit the number of combined sewer overflows at each of its outfall pipes to no more than one per year on average. Outfall 69, located at the base of Vine Street, does not currently meet this requirement.
The Vine Basin CSO Control project will make improvements to the combined wastewater and stormwater system in the Vine Basin so the frequency of overflows at the outfall meets Ecology’s requirements.
