Treatment of water begins with the removal of the larger particles in the water through processes known as coagulation, flocculation, and sedimentation. After the large particles are removed, water is filtered through materials such as sand, gravel, and charcoal to remove dissolved particles. The final stage of treatment involves disinfection using chemicals or ultraviolet irradiation. Hardin County Water Departments may add fluoride to water at this stage as part of a community health effort to support oral health in the general population. Water Departments are responsible for the day-to-day operations and maintenance of Hardin County water treatment facilities. Equipment must also be periodically replaced and treatment processes may also be periodically upgraded.

From the treatment plant, water reaches its customers through a distribution system consisting of pipes, referred to as water mains, storage tanks, and pumping stations. Individual customers connect to water mains to bring public drinking water directly to their properties in Hardin County, Iowa.
