Washington, D.C. Mayor Muriel Bowser has declared a state of emergency and requested federal assistance from President Donald Trump to help address a massive sewage spill that has dumped 250 million gallons of raw sewage into the Potomac River. The leak from a 72-inch pipeline, known as the Potomac Interceptor, began on January 19 and has been an ongoing environmental and public health concern for the region.

Why it matters

The sewage spill has raised major environmental and public health concerns, as the Potomac River is a vital waterway for recreation, wildlife, and drinking water. The declaration of emergency aims to bring in additional federal resources and coordination to repair the leak, assess the damage, and ensure the safety of residents and the local ecosystem.

The details

The leak from the aging Potomac Interceptor pipeline has been ongoing for over a month, with an estimated 250 million gallons of raw sewage spilling into the river in the early stages. DC Water, the local utility, has been working with the EPA and other agencies to try and control the leak, but the mayor has determined that additional federal support is needed to fully address the crisis.

  • The 72-inch Potomac Interceptor pipeline ruptured on January 19, 2026.
  • In the first 5 days, 250 million gallons of untreated sewage was dumped into the Potomac River.
  • On February 20, 2026, Mayor Bowser declared a state of emergency and requested federal assistance.
