In 1925, Gilbert’s domestic water well was drilled to a depth of 475 feet, where a large flow of pure water was found, and a six-inch pipe was sunk to bring the water to the surface. The tower and pumping station were constructed during the latter part of that year. The pump house also occasionally served as a temporary jail to hold rowdy citizens while they sobered up, and before the construction of the town hall in 1938, Gilbert sent law-breakers to Chandler or Mesa. A permanent jail was later located in the rear portion of the building.
