Alternate Water Supply for Halfmoon, Troy and Waterford

This project for the EPA was constructed to serve as an emergency backup.water supply for the Towns of Waterford and Halfmoon and City of Troy.due to upriver dredging PCB-contaminated sediments from the Hudson River.between Fort Edward and Waterford, NY. The public water supplies for both.the Town of Waterford and the Town of Halfmoon currently draw from the.Hudson River within the area targeted for dredging. A Community Health and.Safety Plan, prepared for the project by GE and approved by the USEPA,.required that a viable alternate clean, potable water source be available.prior to the commencement of dredging.

The project is located within Rensselaer County and Saratoga County, New York..The work included all labor, materials, and equipment required to construct a.water transmission main from the City of Troy, New York to the Town of.Halfmoon, New York, including interconnections with the City of Troy,.Town of Waterford, and Town of Halfmoon water treatment plants and/or.water distribution systems.

The water transmission main generally consisted of the following components:

• 2,500 linear feet of 24-inch ductile iron pipe (DIP);
• 20,400 linear feet of 16-inch DIP;
• 100 linear feet of 12-inch DIP, 200 linear feet of l0-inch DIP, 30 linear feet. of 6-inch DIP;
• 10 linear feet of casing pipes installed beneath Routes 4, 32, and railroad tracks;
• 20 gate valves ranging in size from 6-inch to 24-inch; and
• 6 air release valve vaults, 4 flushing hydrants, and 3 metering vaults.

In addition, Schultz Construction was responsible for supporting the contractor.who performed the 1,000 linear feet of directional drilling for a 24″ HDPE.pipline under the Hudson River. Despite the breadth and complicated nature.of the project, it was completed ahead of schedule!
