Built in 1897, the Thomas Hill Standpipe is the oldest standpipe in town and has been in constant use since its construction. In 1895, it was discovered that the city pumping station contained faulty equipment, risking the possibility of a city water shortage, so the city councilmen pushed for a new standpipe on one of the highest points in the city to provide a back-up plan. Its purpose is the same today as when it was built; to help regulate Bangor’s water pressure in the downtown area and to provide water storage for emergencies. The New Jersey Steel and Iron Co. assembled the 50-foot high and 75-foot diameter steel tank atop Thomas Hill, with architect Ashley B. Tower of Holyoke, Massachusetts, designing and overseeing construction of the Shingle style wooden structure to cover the metal structure. Originally, the exterior was painted dark gray with the pillars and lattice work painted white. During World War II, the standpipe was painted olive for camouflage purposes, because of its proximity to Dow Army Airfield, and concerns it would be a target when the Germans ultimately crossed the Atlantic. The tower was completely painted white in 1949.
As Stephen King is synonymous with Maine, Bangor specifically, he used the Thomas Hill Standpipe as the inspiration for the Standpipe in the fictional town of Derry, where Stan first encounters Pennywise (It).
