FOR IMMEDIATE RELEASE

Laurel – February 25, 2016: The Broad Creek Wastewater Pumping Station in Ft. Washington experienced excessive flows on Wednesday night during the heavy rainfall which resulted in a Sanitary Sewer Overflow (SSO) totaling approximately 982,000 gallons. This is a conservative estimate (on the high side) as the actual volume discharged was likely far less than reported. This is due to high tidal backwater conditions in the creek where the external tidal elevation at times was actually higher than the level in the overflow chamber of the station.

The overflow of diluted wastewater impacting Broad Creek started at about 8:19 p.m. on Wednesday and was stopped at about 12:33 a.m. today. All pumps at the station were fully operational during the overflow but were overwhelmed by the volume of flow coming into the station.

WSSC’s water and wastewater systems are separate. The drinking water system was not affected by the overflow.

WSSC crews posted signs and cleaned up the affected area and notifications have been made to the Maryland Department of the Environment, the Prince George’s County Health Department, and local municipalities.
