Essex Elected to ITA ExCo The DC Water Board of Direc- tors approved the Authority's larg- est contract to date for the design and c Boundary T segment of the massive tunnel sys- tem that will bring relief from com- bined sewer overflows (CSOs) to the Anacostia River. This work is part of the larger Clean Rivers Project, a $2.6 billion program to improve the water quality of the Anacostia and Potomac rivers and Rock Creek by increasing the capacity of the sewer system. A joint venture of Salini Impregilo and S.A. Healy was selected based on the high- est technical score and lowest price proposal, therefore providing the best value. The $580 million bid is for design-build, a contract type adopted by DC Water in recent years. Design-build allows for more contractor innovation and greater coordination with the contract owner. Work on the project is expected to begin in September 2017 with completion in 2023, two years ahead of the schedule stipulated in the Consent Decree DC Water signed in 2005 with the U.S. Environmental Protection Agency and the Department of Justice. Onc onnected to the other tunnels already constructed, combined sewer overflows to the Anacostia River will be reduced by 98 percent. In addition to controlling combined sewer overflows, the c will reduce the chance of flooding in the areas it serves from approximately 50 per- cent to 7 percent in any given year. outh of RFK Stadium and terminate at the intersection of Rhode Island Avenue and 6th Stre oposed soft ground tunnel will be 23 ft in diameter, constructed with precast concrete segments, approximately 50 to 160 ft below the ground surfac d to intersect with existing chronic flood areas along Rhode Island Avenue. Diversion facilities will be con- structed to capture flows from the existing sewer system and divert them into the tunnel. Ultimately, all flow captured by the system will be conveyed to DC Water's Blue Plains Advanced Wastewater Treatment Plant. In addition to the tunnel and div o include the construction of ventilation con- trol facilities, stormwater inlets and green infrastructure.
