Infrastructure Wonders: Anacostia River Tunnel

Infrastructure Wonders: Anacostia River Tunnel

Beneath Washington D.C. lies a tunnel that protects the city and its rivers!

The Anacostia River Tunnel project, part of the Clean Rivers project of DC Water, involved the construction of a hydraulic tunnel which will mainly be developed under the Anacostia River, a tributary of the Potomac River in Washington.

The tunnel directs 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.
