DC Water is advising the public of a Sanitary Sewer Overflow (SSO) that occurred early this morning, while performing ongoing repairs on the Anacostia Force Main in Northeast DC. At approximately 1:40 a.m. the sewer line experienced a short-term, unexpected surge in flow that exceeded the capacity.  

Wastewater from the open repair site overflowed into the streets at Anacostia Avenue and Ponds Street Northeast and into a nearby storm drain inlet which leads to the Anacostia River. The volume of wastewater is estimated to be about the same – 6,200 gallons - as the overflow that occurred immediately after the pipe’s collapse. 

Clean-up efforts are underway to remove debris and sanitize the surrounding streets and sidewalks and should be completed later today. There is no impact to the nearby Kenilworth Park & Aquatic Gardens.  

The Anacostia Force Main first collapsed on July 20 and carries wastewater from WSSC  Water to the DC Water’s Blue Plains Advanced Wastewater Treatment Plant. Containment structures are in place to prevent overflows during heavy rainfall events, however, during dry conditions when work is underway one section of the retaining wall must be open to access the sewer pipe. 

During overnight work, DC Water works closely with WSSC Water to restrict the flow of wastewater to allow repairs and cleaning to occur. We are reviewing current procedures to ensure appropriate processes are followed to avoid another unexpected increase in flow during dry weather conditions. 

Untreated sewage can contain many pathogens causing a variety of illnesses ranging from E. coli to hepatitis. If people come in contact with the untreated overflow, they risk getting sick and bringing these pathogens into their homes; and should take the steps below:  

• Leave the area immediately.
• Wash exposed skin thoroughly with soap and clean water.
• Disinfect any affected areas or items.
• Do not consume food or water that may have been exposed.
• Seek medical attention if symptoms occur.
• Report exposure to DC Water at (202) 612-3400. 

It is important to note that DC Water's drinking water system is separate from the wastewater system and is NOT affected by the overflows.
