M Street Diversion Sewer Project
As part of the Clean Rivers Project, the M Street Diversion Sewer was constructed to divert flows from existing combined sewers using three diversion chambers. The diversion chambers convey flow to a series of large sewer tunnels below M Street SE, which connect to the Anacostia River Tunnel near the intersection of Water Street SE. The M Street Diversion Sewer components are designed to deliver a total of 695 million gallons per day of combined sewer flows to the Anacostia River Tunnel. Work along M Street SE also included the rehabilitation of key components of DC Water's existing infrastructure.
Construction of the M Street Diversion Sewer was completed in 2014. The diversion chambers and sewers will be placed into permanent operation in March 2018 when the Clean Rivers system is brought online.
