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.
The first phase of the Clean Rivers Project to control combined sewer overflows to the Anacostia River is nearly complete. Nannie, the tunnel boring machine named after the famous District educator, Nannie Helen Burroughs, finished the construction of the mile long Anacostia. Agenda Welcome Carlton Ray, Director, DC Water's Clean Rivers Project Remarks.

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.

Mining has already begun for the next phase of the projectthe Northeast boundary tunnel, a 5-mile tunnel that will connect with the existing tunnel into the center of the city where flooding has been a problem. This exciting new chapter — a viable solution for present and future generations — will ensure protection of the environment today and for years to come. The Division H — Anacostia River Tunnel, which holds million gallons of combined sewage and measures 23 ft in diameter, was commissioned in late March
