(Bob Barnard / WTTG FOX 5)OLNEY, Md. -
Crews are working to stop a sewage overflow going into the Reddy Branch Creek in Olney.
Washington Suburban Sanitary Commission (WSSC) says the sewage overflow was discovered Tuesday at around 11:30 a.m. and is coming from a 16-inch force main.
Workers have found the pipe, but they have not pinpointed the break. The pipe is located near other underground utility lines, making the break more difficult to find.
The cause is still undetermined.
WSSC says most of the overflow is coming from manholes near the Reddy Branch Wastewater Pumping station. The flow rate is varying, ranging up to 500 gallons per minute.
The pumping station was shut down to relieve pressure on the force main and to help with the repair.
The Maryland Department of the Environment and the Montgomery County Department of the Environmental Protection have been notified.
