CHESHIRE, CTThe Lane Construction Corporation, the U.S. subsidiary of Salini Impregilo Group, has won its first contract in the state of Washington to build a water storage tunnel to reduce polluted overflows into the Seattle, Washington Lake Washington Ship Canal. The contract is valued at $255 million.

Sewage and stormwater from many older parts of the City of Seattle, including the Ballard, Fremont, Wallingford, and Queen Anne neighborhoods, is collected and conveyed in one set of pipes. In dry weather conditions, all sewage flows to a local wastewater treatment plant. During wet weather conditions, polluted runoff can exceed the pipes’ capacity and send a mixture of stormwater (90%) and sewage (10%) to outfalls that flow into the nearest water body. These combined sewer overflows, or CSOs, contain contaminants that can make people sick and harm fish, wildlife, and the environment.

The 2.7-mile, 18’10” internal diameter tunnel, known as the Ship Canal Water Quality Project –Storage Tunnel project, will keep more than 75 million gallons of polluted stormwater and sewage out of the Lake Washington Ship Canal, Salmon Bay, and Lake Union on average each year.

Construction work is expected to start December 2019 and be completed in 2023.

Lane, along with parent company Salini Impregilo, is currently working on other CSO projects around the country to prevent future polluted overflows in nearby water resources including: the Northeast Boundary Tunnel (NEBT) in Washington, D.C., valued at $580 million; the Dugway Storage Tunnel in Cleveland, Ohio, valued at $153 million; and the Three Rivers Protection & Overflow Reduction Tunnel (3RPORT) in Fort Wayne, Indiana, valued at $188 million.

The company also does work in other sectors including highways, bridges, rail, metro, and mass transit. Key ongoing projects include I-10 Corridor Express Lanes in California; Unionport Bridge in Bronx, New York; and the Purple Line Light Rail Extension in Maryland.
