The Washington Suburban Sanitary Commission is reporting that the two-inch air release valve on the 14-inch pressurized sewer main located near the Hoyles Mill Wastewater Pumping Station in Boyds suffered a break on Monday.
While WSSC emphasizes that drinking water is not affected, the agency estimates that to 9,440 gallons of untreated wastewater was spilled in the area of Hoyles Mill Road and Bubbling Springs Road.
Investigation by WSSC confirmed that the ARV break occurred at 2:30 am on June 13, and was stopped at 3:00 pm when the stations pumps were turned off to facilitate repairs. It is estimated that 9,440 gallons overflowed from the break site, according WSSC.
The pumps continued to be shut down to facilitate the repair work that was completed at around 6:00 pm. This has caused an additional overflow from the lowest manhole near the pump station that started at 5:08 pm and ended at 6:08 pm, estimated to be approximately 10,000 gallons. The total overflow volume is 19,440 gallons.
The untreated wastewater did not enter any bodies of water. Appropriate notifications have been made to the Maryland Department of the Environment and the Montgomery County Health Department.
WSSC appreciates notifications from citizens if a sewer back up is suspected. Citizens can call 301-206-4002 at any time to report water or sewer emergencies in Prince George’s or Montgomery counties.
