Project Details

The NEBT is the largest component of the Clean Rivers Project and will start south of RFK Stadium and extend north to Rhode Island Avenue, NE, and west to 6th Street, NW. When complete, the approximately five-mile long tunnel will significantly reduce chronic flooding in the areas it serves, while reducing the amount of combined sewer overflows into the Anacostia River. 

DC Water has worked closely with the District Department of Transportation, the Department of Energy and Environment, and the Washington Metropolitan Area Transit Authority to design a plan that minimizes impact to traffic and pedestrian travel and conserves trees important to the landscape of the neighborhood.
