Sanitary Sewer Overflow Detected into Charles Branch Creek in Upper Marlboro

Drinking Water System Not Affected

| News Release



Laurel – June 21, 2014: There is an ongoing Sanitary Sewer Overflow (SSO) into Charles Branch Creek near 7401 South Osborne Road in Upper Marlboro. The creek bed beneath a 24” sewer main deteriorated, undermining the pipes’ support to the point that it ruptured. It is important to note that WSSC’s drinking water system is separate from the wastewater system and is NOT affected by the overflows. An estimate of the total amount of the SSO will be determined and reported as quickly as possible.

The SSO was detected on Friday, June 20 at around 10:45 p.m. It is in a remote, wooded area which requires the construction of a temporary access road. Waste is flowing from the broken sewer main down the creek approximately 30 feet, and is then re-entering the sewer system via a manhole opening where it will eventually be processed and treated at a wastewater treatment facility. Crews are working to install an over-pump, which will bypass this section of sewer main while repairs are underway.

Notifications have been made to the Maryland Department of the Environment and the Prince George’s County Department of the Environment. WSSC crews have posted signs and will perform all necessary cleanup in the affected area.
