This project has concluded.
The City of Fairfax Public Works Department plans to rehabilitate nearly a quarter mile of aging sanitary sewer force main running beneath San Juan Drive in the Warren Woods neighborhood. Residents living on both sides of the city’s southwestern border with Fairfax County will be impacted. The project will begin Aug. 17 and be completed within 30 days.
Repairing and extending the life of critical wastewater infrastructure prevents failure, which could result in sanitary service disruptions, environmental harm, and more extensive repairs. This project follows the successful relining of the Byrd Drive sanitary sewer force main. The Andes Drive force main will be addressed next.
Spraying a New Pipe Liner The city’s contractor will reline the inside of the four-inch pipe to extend its useful life expectancy. A small device pulled through the length of the pipe will spray a thin layer of epoxy that will harden and form a new lining. This method is more cost effective than full replacement and requires minimal excavation.

Minimal Excavation The city has a maintenance easement on private property for accessing the force main. Excavation within this easement may occur to complete repairs to any section of force main pipe that cannot be lined. Some excavation in the right of way is required.
If necessary, a temporary sewer bypass will be installed to ensure residents’ wastewater service remains uninterrupted. The work may require short-term lane closures, and some areas may be coned off for several days.
