The original pump house was built in 1868, with additions in 1897 and 1912, plus a dam, trash racks, head gates and tailrace.","why_significant":"The nomination argues the station is historically significant for its role in Ogdensburg's growth after the city was chartered in 1868, when it was the sole source of the city's water until 1912. It is also architecturally and mechanically significant as a rare, intact late nineteenth century municipal pumping station in northern New York, retaining much of its historic machinery.","narrative":"Built in 1868 on the eastern bank of the Oswegatchie River in Ogdensburg, this limestone pumping station supplied the city's first public water system. The two-story square pump house has a tower projection at each corner, walls about twenty-four inches thick, a hipped metal roof, and a seven-room superintendent's apartment upstairs. Additions followed in 1897, designed by architect A.A. Paquette to match the original stonework and house steam and turbine equipment, and in 1912, when a small concrete wing held a hydroelectric generator. A concrete dam from 1910, trash racks, head gates and a tailrace complete the site. The station was the city's only water source until 1912, when a filtration plant on the St. Lawrence River took over, and it continued in a supporting role until 1974. Turbines, a centrifugal pump, a generator and control gauges remain in place. The property is listed for its role in the city's growth and as a rare surviving example of a nineteenth century municipal waterworks.","period_of_significance":"1868 - 1940","architect_builder":"Original building unknown; 1897 additions by A.A.
