CSO 019 Overflow Structure Project
The CSO 019 Overflow Structure Project is located on National Park Service property, just south of RFK Stadium, and includes the construction of a tunnel overflow structure. The overflow structure will control tunnel overflows to the Anacostia River when its capacity is exceeded while providing solids and floatable control. The overflow structure was built into the landscape, includes an extensive planting plan along the Anacostia Riverwalk Trail and has been architecturally designed to provide a scenic overlook of the Anacostia River.
The overflow structure was completed in late 2013 and will be placed into permanent operation in March 2018 when the Clean Rivers system is brought online.
