DC Water Clean Rivers Project

McKissack & McKissack is preparing preliminary plans for the Anacostia River Projects called for under the Clean Rivers Project.
In 2004, DC Water launched this initiative to limit the number of overflows from the District of Columbia’s combined sewer system during heavy rainstorms into the Anacostia and Potomac Rivers as well as Rock Creek Park. This $2.2 billion project, formerly the Long Term Control Plan, is slated to be completed in 2025. The project team is preparing the preliminary design/build documents for the 15 sections that comprise the 15.5-mile alignment. The new combined sewer overflow tunnel system will help reduce water pollution by storing up to 75 million gallons of wastewater underground until there is hydraulic capacity to treat it at the Blue Plains Advanced Wastewater Treatment Plant. Three major tunnel projects will merge to form the system.
