Project Details
The Northeast Boundary Tunnel (NEBT) is the largest component of the Clean Rivers Project. It begins south of RFK Stadium and will extend north to Rhode Island Avenue NE and west to 6th Street NW. Once the NEBT is connected to the Anacostia River Tunnel and the First Street Tunnel, combined sewer overflows to the Anacostia River will be reduced by 98 percent. In addition to controlling combined sewer overflows, the Northeast Boundary Tunnel will reduce the chance of flooding in the areas it serves to a 7 percent chance in any given year.
