What We Do

Anacostia River Tunnel Project

The District of Columbia Water and Sewer Authority (DC Water) is implementing its Clean Rivers Project for the District's combined sewer system. The project comprises a system of tunnels and diversion sewers for the capture of combined sewer overflows (CSOs) to Rock Creek, Anacostia and Potomac rivers for treatment at DC Water's Blue Plains Advanced Wastewater Treatment Plant. The Clean Rivers Project will reduce CSOs annually by 96 percent throughout the system and by 98 percent for the Anacostia River alone.

The Anacostia River Tunnel is the second in a series of four tunnels that will mitigate sewer overflows throughout the District of Columbia. The 23 foot in diameter tunnel will be approximately 12,500 feet in length and extend from Robert F. Kennedy (RFK) Stadium in northeast DC to the Poplar Point Pumping Station in southeast DC. Construction of the tunnel will take place in soft ground primarily in public space, 100 feet deep underground. The Anacostia River Tunnel will also include:

  • Six Construction Staging Areas (CSA's) from CSO-019 (RFK) to Poplar Point
  • Construction of six Drop/Junction Shafts and One Existing at Poplar Point
  • Three Adits (Shaft to Tunnel) Connections
  • Five Odor Control and Ventilation Facilities
  • Two Diversion Chambers

The shafts located along the Anacostia River Tunnel will serve as access points for the tunnel and will assist in discharging CSOs to the tunnel.

Construction on the Anacostia River Tunnel began in June 2013 with an anticipated completion date of November 2017.
