The length of water main to be lined will be approximately 950 feet. The Work also includes installation of approximately 270 feet of 8-inch ductile iron water main. Existing AC pipe will be removed within the access pits to install the liner and will be replaced with new 8-inch DI water main and tied-in to the existing main. Gate valves and hydrant assemblies within the limits of work will also be replaced with new DI valves and hydrant assemblies. The demolished 8-inch AC water main pipe and asbestos-contaminated material (ACM) will require removal and legal disposal. Temporary bypass piping will be required as shown and indicated within the Contract Documents. The Contractor shall account for the excavation moratorium on Town and State roads between November 1 and April 1.
