FOR IMMEDIATE RELEASE
Laurel, Maryland – October 12, 2013: There was a Sanitary Sewer Overflow (SSO) at the Washington Suburban Sanitary Commission’s (WSSC) Piscataway Wastewater Treatment Plant in Accokeek today. The SSO began at about 12:45 a.m. and ended at approximately 3:00 a.m. It is estimated that 6,000,000 gallons of diluted wastewater overflowed and was contained on the plant grounds.
The combination of excessive rainfall and a closed valve caused the overflow. Because flows at the plant were higher than normal and a valve was closed, wastewater was able to reach a piece of equipment that was out of service and overflow.
The Commission’s drinking water system is separate from the wastewater system. WSSC’s drinking water is safe and was not affected by this overflow.
The Maryland Department of the Environment and the Prince George’s County Health Department have been notified of the overflow. WSSC crews have cleaned up debris on the plant grounds and spread lime.
