The Thomas Hill standpipe, designed by Ashley B. Tower of Tower and Wallace of New York and Holyoke, Mass., was built in 1897 by Major James M. Davis on land once owned by the Thomas brothers. Constructed in just six months with a portable sawmill and blacksmith shop erected on site, it consists of two structures: a 1.75 million gallon riveted steel tank enclosed by a wooden jacket. The tank is 75 feet in diameter and 50 feet tall, topped by a carousel, a three-ton steel drum connected to the sides of the building by 24 iron trusses. The wooden jacket is 110 feet high and 85 feet in diameter, made of twenty-four 12 inch by 12 inch by 48 feet hard pine main posts covered by 42,000 board-feet of hard pine and 220,000 cedar shingles. It stands on a stone foundation 9 feet high and 3 1/2 feet thick, with a 100-step winding staircase leading to a 12 foot wide promenade deck overlooking Bangor and surrounding communities. Finished with a 38-foot high flagpole and a railing of 192 banisters that gives it the appearance of a large wedding cake or crown when lit at night, it continues to provide water storage and regulate water pressure for downtown Bangor.
