DC Water awards $330M tunnel contract for clean rivers project

The District of Columbia Water and Sewer Authority (DC Water) Board of Directors has approved the Authority’s largest contract to date, for the design and construction of a storage and conveyance tunnel as part of the Clean Rivers Project.

The Clean Rivers Project is a 20-year, $2.6 billion program to reduce combined-sewer runoff to the Anacostia and Potomac Rivers and Rock Creek by 96 percent. A $330.5 million contract awarded by the Authority will cover the design and construction of the first section: the Blue Plains Tunnel, with excavation to begin in July. The joint venture of Traylor Brothers-Skanska-JayDee delivered the highest-scoring technical proposal and the lowest price.
