Wastewater Contained Following Sewer Main Break at the Piscataway Wastewater Treatment Plant

Drinking Water System Not Affected

Laurel – February 13, 2017 – (RealEstateRama) — Working around the clock last night following the rupture of a pressurized sewer main yesterday afternoon, WSSC crews have contained the wastewater overflow at the Piscataway Wastewater Treatment Plant on Farmington Road in Accokeek.

The main broke about 1:40 p.m. on Thursday. WSSC immediately mobilized to set up temporary pipes and pumps (see pictures to the right) to move the wastewater into retention basins on the plant grounds. The pumps were operational about 11:20 p.m. on Thursday.

It is estimated that 3.3 million gallons of untreated wastewater overflowed prior to the start of the temporary pumping operation, affecting the Piscataway Creek.

After the broken sewer main is repaired, WSSC will pump the wastewater out of the retention basins for treatment. At that point, an estimated total volume of the overflow will be calculated.

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

The Piscataway Plant treats about 24 million gallons of wastewater per day. Approximately half of that is being treated as normal. The other half is moving through the temporary pipes into the on-site retention basins.

WSSC contractors are currently at the plant, excavating the broken sewer main. Once the pipe is exposed, crews can determine the type of repair work that is needed. This will be a multi-day repair effort.

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

Twenty-seven signs have been posted in the area of the overflow, along the Piscataway Creek and WSSC will take all appropriate measures to clean up the affected area.
