Sewage and stormwater from many older parts of Seattle all funnels into shared pipes that lead to King County’s treatment plant in Magnolia. During heavy rains, these pipes can reach their capacity. When the pipes are too full, they can overflow into our lakes and waterways.
SPU is working with King County to design and build the Ship Canal Water Quality Project. This underground storage tunnel will capture sewage and stormwater from the Ballard, Fremont, Wallingford and north Queen Anne areas. The project will keep more than 75 million gallons of polluted water out of the Lake Washington Ship Canal, Salmon Bay, and Lake Union each year. Combining efforts will help King County meet their Combined Sewer Overflow Control Program requirements, “Protecting Our Waters”. In addition, working together will be more cost-effective and pose fewer impacts to the community. This video explains the project need and proposed solution.
