Built in 1913 at a cost of $35,000. In 1969, the Riverside Historical Society moved in the east well house, and the Recreation Office moved into the pump house in 1999. In 1990, a fire in the pump house resulted in extensive repairs, including the removal of the engineer’s attic apartment to provide additional office space and the redesign of the front entrance. In 2005, work started on a major construction project to restore the water tower to its 1913 appearance.
