Officials at the Washington Suburban Sanitary Commission (WSSC) on Friday said that 269,325 gallons of untreated sewage flowed into Reddy Branch Creek in Brookville after a sewer pipe burst earlier this week.

The overflow, which did not affect the safety of drinking water, began about 6:30 p.m. Tuesday and ended just before 6 p.m. Wednesday. It began after a  16-inch pressurized sewer main broke in a heavily wooded area near the 200 block of Market Street in Brookeville. Officials were alerted to the break by a local resident who was walking his dog in the area and noticed  that the ground was unusually damp.

WSSC officials shut down the Reddy Branch Wastewater Pumping Station on Brighton Dam Road, which is just a few hundred feet from the site of the break, while the main was repaired.

Septic haulers were brought in and  were able to haul away a total of 241,200 gallons of wastewater.  The pumping station went back into service shortly after the pipe was fixed Wednesday.

WSSC’s drinking water system was not affected by the break because its  water and sewer systems are separate.

Officials have posted signs alerting citizens to avoid the area where the overflow occurred. The Maryland Department of the Environment, the Montgomery County Department of Environmental Protection and local municipalities have been notified of the situation. Efforts to restore the area are underway.
