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.
