The Prince William County Service Authority will begin performing important preventative maintenance on the sanitary sewer system in the Woodbridge neighborhood of Marumsco Village on November 7.
The Service Authority will be lining sewer mains off Carter Lane and Hylton Avenue with work scheduled to be finished in 12 weeks.
The project entails lining sewer mains with Cured-In-Place-Pipe. The lining process is an alternative to replacing the pipe itself, which is a more costly and disruptive measure for both customers and the utility.
The resin-like substance used in the CIPP process hardens, essentially becoming a new pipe inside the existing sewer main. This protects the main from tree root intrusion and corrosion that can occur over long periods of time. CIPP also prevents groundwater from seeping into the sanitary sewer system during rain events, which helps reduce the amount of flow to the wastewater treatment plant.
The average sewer pipe lasts about 40 years, while CIPP can extend that lifespan to 90 years.
Each year, the Service Authority video inspects more than a hundred miles of sewer line to determine where CIPP would be most effective. This fall, the Service Authority has also lined sewer mains in neighborhoods in Occoquan, Montclair and Dumfries.
