The Charles City Water Treatment Plant pumps an average of 2,500,000 gallons per day.  The new water treatment plant was finished in 2010 and has a maximum operating capacity of 5,000,000 gallons per day.   The water is softened with lime, with an average hardness of 116 mg/L (6.78 grains). This water is pumped from the Cedar Valley Aquifer using three active wells.

The plant is in operation twenty-four hours a day, 365 days a year.  Water quality testing is done daily, including weekends and holidays. The plant and distribution system are monitored and maintained by four state licensed operators.
