TSJD Wins $330m Sewerage Tunnel Contract

The joint venture of Traylor Brothers-Skanska-JayDee (TSJD) has received a $330m contract to design and construct a storage and conveyance tunnel in Columbia, US.

The contract will be delivered by the District of Columbia Water and Sewer Authority (DC Water), as part of the state’s $2.6bn Clean Rivers project.

The tunnel will help in reducing the combined-sewer runoff to the Anacostia and Potamac rivers and Rock Creel by 96%.

DC Water general manager George Hawkins said the Clean Rivers project will be this generation’s most important step towards improving the district’s waterways.

The joint venture company will begin the excavation work in July.
