The Prince William County Service Authority is starting rehabilitation work this week on the sewer system on Tripoli Boulevard in Dumfries.
According to a release, the project will take around four weeks to complete, and will include lining sewers on “Tripoli Boulevard, Dumfries Road, Wilson Street, Maple Street, Diamond Point Mews, Pine Street and Pine Court with Cured-In-Place-Pipe. The lining process is done in lieu of replacing the pipe itself, which is often a much more costly and disruptive measure for both customers and the utility,” stated a release.
More on the project, from a release:
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.
The average sewer pipe lasts about 40 years, while CIPP can extend that lifespan to 90 years.
Each year, the Service Authority inspects more than a hundred miles of sewer line to determine where CIPP would be most effective. The Service Authority has lined more than five miles worth of sewer main in the last six months.
