Service Authority: We stopped the groundwater leak into Gainesville sewer

GAINESVILLE, Va. — The Prince William Service Authority reports it sealed a pipe where tens of thousands of gallons of ground water was seeping daily into the pipe. 

From the Service Authority: 

This fall, the Service Authority discovered groundwater entering into the sanitary sewer system through a small, unused section of sewer main near the intersection of Glenkirk Road and Linton Hall Road. The estimated amount of water seeping into the 350-foot line was 68,000 gallons a day – or the equivalent of 24 hours of water consumption by 180 homes.

Eventually, that water flowed to the  to be treated as wastewater.

Eventually, that water flowed to the H.L. Mooney Advanced Water Reclamation Facility  Upper Occoquan Service Authority’s (UOSA) wastewater treatment plant in Centreville to be treated as wastewater.

Since the line is not currently in use, the Service Authority was able to seal it off at the nearest manhole to prevent any more infiltration of groundwater. Ultimately, this discovery will save money on treatment cost, free up capacity at UOSA and, most importantly, help to save our customers money.

It’s not known what caused when the groundwater to begin seeping into the pipe, but it was likely after improvements were made to the intersection and the line was abandoned, according to a Service Authority statement.
