The Prince William County Service Authority (PWCSA) has started sewer rehab work near the Potomac Festival shopping center and Telegraph Road in Woodbridge.
According to a release, the rehab work is “trenchless”, which means there will be no traffic impacts.
More on the project, from a release:
The inside of sanitary sewer pipes will be lined with a resin-like substance, called Cured-in-Place-Pipe or CIPP, which helps protect 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.
The work will take around six weeks to complete.
