They are significant under Criterion C in engineering for their link to the development of water supply technology and sanitation in rural Virginia. The system also supplied water during the 1931 fire that destroyed downtown Hillsville.","narrative":"Along a spring branch below downtown Hillsville, Virginia, four small concrete housings shelter hydraulic rams, devices that use flowing water to pump a portion of it uphill without outside power. Downstream stands a tile block pumphouse built over a concrete reservoir and containing a gasoline engine for backup. The system dates to about 1924 and was installed by industrialist George L. Carter to supply his wife's summer house and other Hillsville buildings, including a bank and a hotel. It is regarded as a fairly complete example of a technology that was once common on American farms. The rams also provided water during the 1931 fire that destroyed the town center. Electric pumping systems gradually replaced them, and they were abandoned in the late 1950s. The setting includes a remnant of a white pine grove planted in 1938. Some concrete is deteriorating and the elevated water tank is gone. The county plans to turn the site into a community park with interpretation.","period_of_significance":"Ca. 1924","architect_builder":"unknown","architectural_style":"No Style","criteria":["C"],"status_note":"Listed function is vacant/not in use; the rams were abandoned in the late 1950s.
