It also reflects the growth of the town water supply, its municipal takeover in 1905, and later upgrades through electrification. Its Late Victorian, nominally Colonial Revival design adds architectural interest.","narrative":"Overlooking Lake Tashmoo in Tisbury, this 1½-story brick pumping station was completed in 1887 to supply water to the town on Martha's Vineyard. It has an L-shaped plan, granite lintels, a tall hipped roof with four dormers and a tapered brick stack. Additions came in 1907, 1930 and 1932 as boilers were enlarged and electric pumps replaced steam equipment. The site also holds a 1919 garage, an early 20th-century shed, a 1924 intake tank, a valve cover, entrance pillars, a reservoir and a dike built in 1938-1939. Built by the Vineyard Haven Water Company, it is the earliest known waterworks on the island and served as a model for later ones. Tisbury bought the system in 1905 after a court ruling. The station is now vacant and deteriorating, though its integrity is high, and the surrounding land is used for recreation.","period_of_significance":null,"architect_builder":null,"architectural_style":"Late Victorian: Colonial Revival","criteria":[],"status_note":"The pumping station building is unused, deteriorating and covered with brush, with all machinery removed.
