It is owned by the City of Roanoke.","why_significant":"The nomination calls it one of Virginia's more interesting artifacts of industrial archaeology, tied closely to Roanoke's growth. The Snow duplex pump, with Corliss valve control, is believed to be a unique survivor of its type. Crystal Spring has supplied water to the Roanoke Valley since prehistoric times and helped the city grow.","narrative":"Crystal Spring Steam Pumping Station is a one-story, common-bond brick pump house in Roanoke, Virginia, built beside a spring that has served people in the valley since prehistoric times. Inside is a horizontal cross-compound Snow steam pumping engine, installed in 1905 by the Snow Steam Pump Works of Buffalo, New York. It has Corliss valve gear and an eleven-ton, thirteen-foot flywheel, and it pumped up to five million gallons of spring water a day to a reservoir on Mill Mountain. Steam operation ended in the late 1950s, when an electric pump replaced it. The engine is believed to be a unique survivor of its type, and the site is described as an important example of industrial archaeology tied to Roanoke's growth. Local citizens and corporations restored the building and machinery during the Bicentennial, using old photographs, blueprints and advice from Worthington Company officials. A concealed motor now turns the engine for visitors, and a glass hatch shows the spring.","period_of_significance":"1905","architect_builder":"Snow Steam Pump Works (Snow Steam Pump Company), Buffalo, N.Y.; supplied by J.B.
