A Parsons Corp. joint venture has been selected to design and build an expansion to the Anacostia River’s tunnel system as part of a $2.6 billion clean rivers project.
The joint venture of Parsons, Impregilo and Healy have been awarded $254 million to build the 23 foot wide and 12,400 linear foot second portion of the Anacostia River Tunnel which is meant to avoid sewer overflows, Parsons said Wednesday.
Virginia Grebbien, Parsons group president, said, “Parsons has successfully delivered more than 25,000 water and wastewater projects worldwide, and we look forward to working with Impregilo and Healy to deliver this important project to the national capital region.”
Parsons will serve as lead designer and is a 35 percent shareholder in the joint venture.
According to the company, construction of the tunnel will start in 2017.
Parsons said that the Anacostia River Tunnel is part of the Clean Rivers Project which aims to “reduce combined-sewer runoff to the Anacostia and Potomac rivers and Rock Creek by 96percent.”
