DC Water Sewer Main Damage Affects Nine Zip Codes

WSSC Jan 27, 2026
DC Water is operating a bypass pump system to divert wastewater from a damaged sewer main near the Clara Barton Parkway and C&O National Historical Park. Residents in nine affected zip codes — including parts of Bethesda, Potomac, Rockville, Gaithersburg, Glen Echo, and Cabin John — are urged not to pour grease down drains or flush wipes, as these materials are clogging the bypass pumps. WSSC is passing along the alert on DC Water's behalf.
