Emergency work underway on Potomac Interceptor in Maryland to protect drinking water

DC Water has initiated emergency repairs on a corroded 1,700-foot section of the Potomac Interceptor sewer line near Lock 22 on the C&O Canal in Maryland. A spill at this location could threaten the drinking water intakes for WSSC Water and Washington Aqueduct, though Fairfax Water’s intake would remain unaffected. Crews are installing a temporary bypass system while the compromised pipe is replaced, with work expected to last through September.
