Sewage overflow causes traffic delays near Clara Barton Parkway in Montgomery County

A broken sewage pipe in Montgomery County is causing traffic for commuters in Montgomery County Tuesday morning, according to DC Water.

Crews saw wastewater flowing from the Potomac Interceptor sewer line in C & O Canal National Historical Park Monday night. Crews are working to contain the overflow and assess damage.

The right inbound lane near Clara Barton Parkway east of the Capital Beltway is closed. There is no timeline as to when the pipe could be repaired.

DC Water says commuters should expect delays and should consider taking alternative routes. Trails and parking near the parkway could be impacted. Residents who live in the area might smell an odor from the sewage.

The pipe’s overflow is expected to reach the Potomac River. Drinking water won’t be affected because DC Water’s drinking water system is separate from the wastewater system.

DC Water says untreated sewage could contain pathogens that cause a various illnesses ranging from E. coli to hepatitis. If you or someone you know comes in contact with the sewage, DC Water says to do the following:

• 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.
