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.

Soil Removal Nearing Completion between C & O Canal locks 13 and 14, Reaching Clay Liner

DC Water and its contractor have made significant progress on soil removal, reaching the clay liner between locks 13 and 14 of the C & O Canal, which was used as a bypass for wastewater during the Potomac Interceptor repairs.

Work continues to remove sludge between locks 10 and 13, which is expected to be completed by mid- to late-April. The soil will then be removed down to the clay liner as the final step, and the canal reconstructed to meet National Park Service specifications.
