Heavy Overnight Rainfall Causes Sewerage Overflows in Prince George’s County

WSSC Water Crews Quickly Responded to Three Separate Incidences Drinking Water System NOT Affected

| News Release



Laurel, Md. – July 7, 2020 – WSSC Water crews quickly responded to three separate sewerage overflow incidences today caused by last night’s excessive rainfall - two Sanitary Sewer Overflows (SSO) and an on-property facility spill of partially treated wastewater on the grounds of WSSC Water’s Piscataway Water Resource Recovery Facility (WRRF).

The Piscataway WRRF facility spill of partially treated wastewater started at approximately 4:40 a.m. today and ended about four hours later at 8:27 a.m. The total volume of partially treated wastewater spilled is estimated to be 2.3 million gallons.

The first SSO occurred on Farmington Road in Accokeek and began at approximately 6:15 a.m. today and ended at approximately 4:25 p.m. The estimated volume of the overflow is approximately 18,300 gallons of diluted wastewater. The second SSO occurred on Piscataway Drive in Fort Washington and began at approximately 7:15 a.m. and ended at 2:30 p.m. The estimated volume of the overflow is approximately 32,475 gallons of diluted wastewater.

The two SSOs and the facility spill caused wastewater to enter Piscataway Creek. WSSC Water crews will clean up impacted areas and post signs alerting residents to avoid the areas.

It is important to note that WSSC Water’s sewer and water systems are separate. The overflows and facility spill are NOT affecting drinking water.
