Excessive Rainfall Causes Two Sanitary Sewer Overflows In Prince George’s County

Drinking Water System Not Affected

| News Release



Laurel, Md. – December 16, 2018 - Heavy rainfall this weekend caused two Sanitary Sewer Overflows (SSO) in Prince George’s County, one at WSSC’s Broad Creek Wastewater Pumping Station located on Livingston Road in Fort Washington, and the other near WSSC’s Piscataway Water Resource Recovery Facility (WRRF) located on Farmington Road in Accokeek.

The overflow at the Broad Creek Wastewater Pumping Station began on Saturday, December 15, at approximately 10:25 p.m. and ended at about 3:10 a.m. on Sunday, December 16. The volume of the overflow is estimated to be 690,000 gallons of diluted wastewater, which entered a drainage ditch that leads to Broad Creek. The station was fully operational, however the significant rainfall overwhelmed the station’s pumping capacity. WSSC crews cleared debris, cleaned around the station, and posted sixteen signs warning residents to avoid the area.

During the prolonged rain event, WSSC also responded to a SSO near its Piscataway WRRF, which started on Saturday, December 15, at about 8:45 p.m. The overflow stopped on Sunday, December 16, at about 10:41 a.m., and then restarted at about 1:30 p.m. and is currently ongoing. The wastewater is flowing into Piscataway Creek. Once this overflow stops, a total volume will be determined. The impacted area will be cleaned up and signs will be posted warning residents to avoid the area.

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

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