WSSC Responds to Wastewater Spill at Piscataway Water Resource Recovery Facility

Equipment Malfunction Causes Spill Drinking Water System Not Affected

| News Release



Laurel, Md. – July 29, 2019 – WSSC crews responded to and repaired an equipment malfunction that led to a facility spill of partially treated wastewater at its Piscataway Water Resource Recovery Facility (WRRF) in Accokeek on Sunday, July 28. The spill was discovered at 7:37 p.m. and stopped at 7:50 p.m. The volume of the spill is estimated to be 230,000 gallons of partially treated wastewater that entered a storm drain and flowed into Piscataway Creek.

It is important to note that WSSC’s water and wastewater systems are separate. The overflow is not affecting WSSC’s drinking water.

The spill occurred as a result of a pump malfunction. WSSC crews quickly repaired the pump to stop the spill. Staff at the Piscataway WRRF have cleaned up the area and posted signs warning residents to avoid the area.

Notifications have been made to the Maryland Department of the Environment and the Prince George’s County Health Department.
