Millions Gallons of Sewage Flood Potomac River
24 Jan
Summary
- A 72-inch sewage pipe ruptured, releasing millions of gallons of raw wastewater.
- Environmentalists warn of horrific smell and public health risks from high sewage concentrations.
- Drinking water supply remains unaffected; repair efforts continue through the weekend.

A critical 72-inch sewage pipe experienced a collapse late on Monday, leading to a significant pollution event in the Potomac River northwest of Washington D.C. This rupture has unleashed millions of gallons of raw wastewater, creating a dire environmental situation.
DC Water is implementing emergency measures, utilizing pumps to divert wastewater around the rupture. Simultaneously, repair teams are commencing work, with crews working to remove lock gates on the nearby canal for a temporary rerouting of sewage. This complex rerouting aims to divert wastewater upstream into the canal before returning it to the sewer system downstream of the affected pipe.
Dean Naujoks, the Potomac Riverkeeper, described the scene as "dire," highlighting the horrific smell and the public health risks associated with the highly concentrated sewage. He noted that the sewage was bubbling up from the ground in significant volumes. DC Water has advised individuals exposed to the water to wash their skin thoroughly.
Despite the immediate environmental concerns and the anticipation of a major winter storm, DC Water has confirmed that the region's drinking water supply remains secure as it operates on a separate system. Repair efforts are anticipated to persist throughout the weekend, underscoring the ongoing challenges posed by aging infrastructure nationwide, which requires substantial investment.
