WSSC Calculates Volume of Sanitary Sewer Overflows in Prince George’s County


Drinking Water System Not Affected

Laurel, MD – February 15, 2018 – (RealEstateRama) — WSSC has calculated the total volume of the two sanitary sewer overflows (SSOs) caused by excessive rain in Prince George’s County.


The first SSO occurred at WSSC’s Broad Creek Wastewater Pumping Station at 10315 Livingston Road, Ft. Washington, Md., and began at 7:48 a.m. Sunday and ended at 1:20 p.m. Sunday. During the overflow, all six pumps at the station were in operation, however, rainfall totals in excess of three inches from Saturday to Sunday exceeded the station’s maximum pumping capacity. The total amount of untreated wastewater that entered a drainage ditch, which eventually flows into Broad Creek was 520,000 gallons. WSSC crews have cleaned up the affected area and spread lime to neutralize the odor in the wake of the overflow. Sixteen signs have also been posted warning people about the overflow.

The second SSO occurred at 14300 Indian Head Highway, near the Piscataway Wastewater Treatment Plant (address originally reported as 11 Farmington Road W. in Accokeek, Md.), and began at approximately 9:39 a.m. Sunday and ended at 1:30 a.m. today. Due to excessive rainfall, extremely high wastewater flows came into the plant at the time of the SSO, causing a manhole just off the plant’s grounds to overflow. It is estimated that 951,000 gallons of untreated wastewater flowed into Piscataway Creek. WSSC crews have posted 10 signs warning people to avoid the area.

It is important to note that WSSC’s water and wastewater systems are separate. This overflow did NOT affect WSSC’s drinking water.

WSSC notified the Maryland Department of the Environment and the Prince George’s County Health Department.
