Background

On January 19, 2026, a section of the 54-mile Potomac Interceptor (PI) sewer line collapsed along Clara Barton Parkway, in Montgomery County, resulting in a significant overflow into the C & O Canal National Historical Park. The PI carries about 60 million gallons of wastewater daily from as far away as Dulles Airport to the Blue Plains Advanced Wastewater Treatment Plant in Southwest DC for treatment.

DC Water crews and contractors began work immediately to construct a bypass to contain the overflow. The bypass was completed and activated on January 24, utilizing powerful pumps and the C&O Canal to reroute wastewater around the collapsed section of pipe and back into the sewer system. o additional overflows entering the Potomac River have occurred since February 8. Crews are removing rocks and debris from the collapsed section of pipe and emergency repairs are projected to be completed by mid-March.

Protecting public health and the Potomac River remains DC Water’s top priority. For the latest information about the Potomac Interceptor Response, go to dcwater.com/potomac-interceptor-collapse.
