Largest construction project since Metro will eliminate sewage, stormwater pollution
A $2.6 billion project in Washington, D.C., will nearly eliminate combined sewer overflows (CSOs) to Anacostia, Potomac rivers.
A $2.6 billion project in Washington, D.C., will nearly eliminate combined sewer overflows (CSOs) to Rock Creek and the Anacostia and Potomac rivers, helping to improve the Chesapeake Bay’s health.
The Clean Rivers Project, led by the District of Columbia Water and Sewer Authority (DC Water), is the largest construction project in the District since Metro was built.
Combined sewer overflows occur during heavy rainstorms, when the mixture of sewage and stormwater cannot fit in the sewer pipes and overflows to the nearest water body. CSOs direct about 2.5 billion gallons of sewage and stormwater into Rock Creek and the Anacostia and Potomac rivers in an average year.
The Clean Rivers Project consists of massive underground tunnels to store the combined sewage during rainstorms, releasing it to the Blue Plains wastewater treatment plant after the storms subside. The first, and largest, tunnel system will serve the Anacostia River.
