The city's water source is the Indian Creek Reservoir, which is held by an earthen dam built in 1989 and fed by Indian Creek. Our treatment process utilizes water treatment technology to remove both particulate matter and dissolved contaminates from the water before it is disinfected and pumped to the distribution system for delivery to homes or businesses in the water service area.


Provide a safe and adequate domestic water supply to all residents and businesses in the water service area.
