| News Release



Laurel – July 31, 2017: WSSC crews quickly responded to two sewage overflows at the Western Branch Wastewater Treatment Plant located at 6600 Crain Highway in Upper Marlboro on Saturday, July 29.

The first event occurred at approximately 5:45 a.m. and lasted for about 15 minutes. Wastewater flows at the plant were extremely high due to the heavy rains, causing a manhole on the plant grounds to overflow. The manhole is located prior to the start of the treatment process. It is estimated that 100,000 gallons of wastewater overflowed from the manhole and entered Western Branch.

The second event occurred at approximately 11:00 p.m. on Saturday and lasted for about 12 minutes. A pipe connected to a temporary bypass pump broke causing an estimated 20,000 gallons of wastewater to overflow on plant grounds.

Appropriate notifications have been made to the Maryland Department of the Environment and the Prince George’s County Health Department. Signs have been posted at both sites and WSSC crews have cleaned up all affected areas.
