A sewer overflow in Oxon Hill, Maryland, stopped about 5:30 p.m. Wednesday, according to the Washington Suburban Sanitary Commission.
About 15,000 gallons of raw sewage leaked from a 14-inch crack in a sewer main into a low area behind homes on Huron Drive and also spilled into Oxon Run, a nearby creek.
WSSC says sewer mains are harder to fix than broken water mains.
A WSSC contractor put 3,500 feet of temporary 8-inch pipe in place to redirect the wastewater around the broken pipe. A second 3,500-foot section of temporary pipe is in place in case the wastewater exceeds the capacity of the temporary pipe already in use.
Crews will put a camera in the pipe Thursday to examine the damage and then make appropriate repairs.
The spill is not affecting drinking water.
