Project Value: $67M

Construction of a 55-million-gallon reinforced concrete water storage tank consisting of two bays with interior reinforced concrete baffles. The structure includes fifteen 120-inch diameter sluice gates with electric motor operators, two 30-inch diameter butterfly valves, a 6-inch and 8-inch PVC underdrain system, access hatches and vents, and a precast concrete drainage pump station for the storage tank. Transmission of water to and from the tank required constructing 3,600 feet of 120-inch precast concrete cylinder pipe (PCCP) crossing the Wachusett Aqueduct Forebay and connecting to the Aqueduct, 400 feet of 144-inch buried PCCP that also crosses the Forebay, a 30-inch buried ductile iron pressure pipe, and 1,000 feet each of 96-inch and 120-inch buried PCCP including a concrete overflow structure in the Wachusett Aqueduct Open Channel.
