Source of Water in Westerville, United States
Westerville’s tap water comes primarily from Hoover Reservoir, a surface-water reservoir on Big Walnut Creek in central Ohio. The City of Westerville treats this water at its municipal water treatment plant before distributing it to homes and businesses.
Treatment removes sediment, microorganisms, and other contaminants, and the water is disinfected before entering the distribution system. Westerville routinely tests the treated water to ensure it meets U.S. Environmental Protection Agency and Ohio drinking water standards.
