The result was an overflow to the closest body of water. Due to the efficient nature of the pipe installation, open trenches were not required and traffic disruption was kept to a minimum. Since the end of construction on the massive tunnel project in March, it has already prevented billions of gallons of sewage from flowing into the Anacostia River. The tunnel will direct the wastewater and rain water separately to prevent polluting the rivers when there is flooding combined sewer overflows or CSO during periods of intense rain. Follow us on.

    Anacostia River Tunnel Grand Opening

    The Anacostia River Tunnel project, part of the Clean Rivers project of DC Water, involves the construction of a hydraulic tunnel which will mainly be developed under the Anacostia River, a tributary of the Potomac River in Washington. The result was an overflow to the closest body of water. Finally, the shafts and the maintenance chambers are equipped with electromechanical equipment and put into service.

    By the time it is complete, the Clean Water Project will have more than 18 miles of tunnel, including the future Northeast Boundary Tunnel and the Potomac River Tunnel.

Next, microtunneling, a trenchless pipe installation performed by remote-controlled jacking, was used to insert the jacking pipes more than ft below the ground under the CSX Railroad tracks and right of way to connect the CSO outfall to the tunnel system.
