Anacostia Combined Sewer Separation Project, CSO 006

The Anacostia Combined Sewer Separation Project - CSO 006 was initiated in March 2008 as a component of DC WASA's overall Long Term Control Plan for reducing the overflows of the District's combined sewer system which may discharge stormwater and wastewater runoff into area waterways when it rains. This Project will involve adding new pipes that separate the flow of stormwater from wastewater and will reduce the amount of wastewater that enters the Anacostia River.
