The Prince William County Service Authority (PWCSA) is beginning important rehabilitation work this week on a sewer system in Manassas.
According to a release, the work is being done on a system in the Oak Ridge Estates neighborhood off Kahns Road.
“Expected to take approximately 10 weeks to finish, the project entails lining sewer mains on Byrne Place, Danny Lane, Dusty Willow Road, Forest Oak Court, Goshen Court, Kahns Road, Mallard Pond Court, Mariposa Drive, Peak Court, Ridgeway Drive, Silent Willow Court and Spring Drive with Cured-In-Place-Pipe. The lining process is done instead of replacing the pipe itself, which is often a much more costly and disruptive measure,” stated a release.
An average sewer pipe lasts around 40 years, but with the ‘Cured-In-Place-Pipe’ this method can extend the life of the pipe to 90 years, stated PWCSA.
“Once completed, the resin-like substance used in the CIPP process hardens and essentially becomes 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 infiltration into the sanitary sewer system during rain events, which helps reduce the amount of flow to the wastewater treatment plant,” stated a release.
