FOR IMMEDIATE RELEASE

Laurel – May 9, 2016: Last Wednesday (5/4), WSSC’s Piscataway Wastewater Treatment Plant in Accokeek experienced a wastewater spill on-property that started at approximately 3:50 p.m. and ended Thursday morning (5/5) at 7:15 a.m.

The overflow occurred after the initial stage of the treatment process also known as the headworks. The force of the water flow pushed open a manhole cover causing partially treated wastewater to spill into a wooded area on the facility grounds. After further review of the system and spill, an estimated 360,000 gallons of partially treated wastewater were discharged, down from the original estimate of 1.5 million gallons. Of that total, approximately 230,000 gallons were recovered and pumped back into the treatment process, leaving a net of 130,000 gallons of wastewater spilled on the facility grounds. The overflow did not enter any storm drains or reach any body of water.

As a precaution, WSSC posted signs around the area and appropriate notifications were made to the Maryland Department of the Environment and the Prince George’s County Health Department.
