Artesian Water Co. Pumphouse and Wells

The Artesian Water Co. Pumphouse and Wells in Boise, Idaho, United States, houses two pumps that circulate geothermally heated water from wells installed in 1890. Natural hot water from the pumphouse was piped to residential and commercial customers beginning in the 1890s. The rectangular building, 27 feet by 50 feet, has battered walls that conform to the inward slope of two drill derricks which supported the original structure.
