DC Water has hit a major milestone in its Lead Free DC (LFDC) program: the 10,000th lead service line replacement. To commemorate the achievement, we teamed up with Washington Football Legend and NFL Hall of Famer Darrell Green to surprise our honorary 10,000th replacement and homeowner. With this achievement, nearly 25% of the estimated lead service lines in the city have been replaced.

DC Water will be doing construction as part of a sanitary sewer rehabilitation project on Clara Barton Parkway in Maryland from Sept 8 - Oct 10, 2025, which may cause delays inbound near the I-495 Beltway interchange. One lane will be closed in the work zone to reline an 800-foot section of the sewer line, known as the Potomac Inteceptor. Access to the inner and outer loops of the Beltway will remain available. Additional lane closure may be necessary intermittently through Oct 24, 2025.
