Federal prosecutors have launched legal action against Washington DC and its water utility following a catastrophic sewage pipeline failure that released hundreds of millions of gallons of untreated waste into the Potomac River earlier this year.
The Justice Department filed the federal court action Monday targeting both the District of Columbia and DC Water over the environmental disaster that occurred when a massive 72-inch sewer main known as the Potomac Interceptor ruptured on January 19th. The pipeline failure sent raw sewage shooting from underground directly into the river in Montgomery County, Maryland, just outside the nation’s capital.
Officials say the rupture discharged approximately 244 million gallons of untreated sewage into the Potomac, highlighting serious concerns about America’s crumbling infrastructure systems. The damaged pipeline was originally constructed during the 1960s and had been showing signs of deterioration, according to DC Water officials.
The water authority acknowledged it was aware of the pipe’s declining condition and had started rehabilitation efforts on a nearby section about a quarter-mile away from where the break occurred. That repair work had begun in September and was recently finished when the catastrophic failure happened.
Federal prosecutors claim DC Water violated regulations by failing to adequately operate and maintain its sewage infrastructure to prevent untreated waste from entering the Potomac River and its tributaries, as well as other areas where people might be exposed.
“DC Water’s failure to maintain the Potomac Interceptor resulted in raw sewage flowing into the Potomac River and the surrounding environment, posing a direct risk to public health,” Principal Deputy Assistant Attorney General Adam Gustafson stated. “As cities grow and infrastructure ages, cities must invest in their wastewater system to prevent such catastrophes.”
The federal case represents one of two legal actions filed against DC Water on Monday. Maryland Attorney General Anthony Brown simultaneously filed a separate lawsuit in Montgomery County Circuit Court demanding civil penalties and compensation for environmental cleanup costs.
“The utility must take full responsibility for the damage caused and take immediate and lasting action to prevent future spills,” Maryland Department of the Environment Secretary Serena McIlwain said in her statement.
In response, DC Water issued a statement emphasizing its “fully committed to the long-term rehabilitation” of the Potomac Interceptor pipeline. The utility said its top priority was containing the overflow and fixing the damaged pipe section, which it accomplished by “all discharges to the Potomac River within 21 days. The repairs of the affected segment were completed in 55 days. DC Water is working now to accelerate the rehabilitation of more than 2,700 linear feet of pipeline in this area that was previously scheduled for improvement.”
The agency said both lawsuits were currently “under review.”
The environmental crisis generated political controversy, with President Donald Trump criticizing local Democratic officials, particularly Maryland’s Democratic Governor Wes Moore. Washington Mayor Muriel Bowser issued an emergency declaration in February and requested federal assistance from Trump, who approved an emergency declaration several days later that provided federal aid.
Emergency repairs were completed last month, allowing the pipeline to resume normal operations. While the leak has been largely contained, complete restoration of the damaged infrastructure may require several additional months. DC Water continues working with the Environmental Protection Agency to address the leak and assess the river’s environmental impact.
