The Prince William County Service Authority will begin performing important rehabilitation work on the sanitary sewer system in Marumsco Village on Monday, September 25.

The work will take place on several streets in the Woodbridge area including Hylton Avenue, Forest Glen Road, Willow Lane, Pinetree Drive, Greenacre Drive, Maple Leaf Lane, Azalea Lane, Varsity Drive, Orchard Drive, Woodvale Court, Irene Court and Wildwood Court.

The work is expected to take approximately 12 weeks to complete. Because this rehabilitation work is “trenchless,” there will be virtually no impact on traffic. The inside of sanitary sewer pipes will be lined with a resin-like substance, called Cured-in-Place-Pipe or CIPP, which protects the mains from tree root intrusion and corrosion that can occur over long periods of time. The lining process is done instead of replacing the pipe, which is often a much more costly and disruptive measure for both customers and the utility.

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. Since July 2016, the Service Authority has lined nearly 12 miles worth of sewer main.
