Seattle makes significant progress on underground stormwater storage tunnel
(UI) – On June 26, King5 reported that a “significant portion of the construction work” for an underground stormwater and sewage tunnel has been completed in Seattle. The tunnel is part of the Ship Canal Water Quality Project, which aims to keep stormwater and sewage from polluting Seattle waterways. The project is joint effort between Seattle Public Utilities and the King County Wastewater Treatment Division.
According to King5, the tunnel will hold stormwater and sewage that overflows during heavy storms until it’s ready for treatment. The work was completed by a tunnel-boring machine dubbed “MudHoney.” The machine will be taken apart and sold back to its manufacturer in Germany.
Historically, the area (spanning from Ballard to Wallingford) worked with a “combined sewer system,” which caused water to overflow into the Ship Canal. The system will help quell environmental concers associated with the stormwater and sewage overflow, with King Country WTD Director Kamuron Gurol saying the project is “better for salmon, better for orcas and better for people.”
