Webuild Lane TBM MudHoney to Work on Seattle Water Project
Webuild Group’s US subsidiary Lane is preparing to start excavating the storage tunnel for the Ship Canal Water Quality Project in Seattle in Washington after having lowered down a shaft the tunnel-boring machine, recently baptised MudHoney. The project, worth USD 570 million of which Lane has SD 255 million, is one of several being developed by Lane in the clean water sector in the United States. In Seattle, the 4.2-kilometre tunnel will prevent up to 75 million gallons (276 million litres) of untreated stormwater and sewage from flowing into the Lake Washington Ship Canal, Salmon Bay and Lake Union every year. Known as combined sewer overflow, these untreated waters can make people sick, harm fish and wildlife. The tunnel will capture and temporarily hold more than 29 million gallons (109.8 million litres) of stormwater and sewage during heavy rains.
Among Lane’s other projects, there is a Caloosahatchee basin storage reservoir to reduce harmful discharges into an estuary in Florida; the Three Rivers Protection & Overflow Reduction Tunnel in Ft. Wayne, Indiana; the Dugway Storage Tunnel in Cleveland, Ohio; and the Northeast Boundary Tunnel in Washington DC.
