FOR IMMEDIATE RELEASE
Laurel – June 14, 2016 – On June 13, a two inch air release valve (ARV) on a 14 inch pressurized sewer main broke near the Hoyles Mill Wastewater Pumping Station (WWPS) in Montgomery County. Yesterday it was reported that the break was on the 14 inch sewer main.
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.
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.
