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.
