The Water Treatment Plant (WTP) staff provides customer service and maintains the WTP. Treatment includes settling, softening, filtration, and disinfection. The WTP has the capability to treat 20 million gallons per day (mgd) of raw water, ten mgd from the Smoky Hill River and ten mgd from the downtown well field (17 wells). The WTP currently treats approximately five mgd in the winter and up to ten mgd in the summer. Total water treated in 2020 was 1.82 billion gallons, which included 0.83 billion gallons from the Smoky Hill River and 0.99 billion gallons from the Downtown Well Field. The water is chemically treated to meet or exceed the standards of the Kansas State Department of Health and Environment (KDHE) and the U.S. Environmental Protection Agency (EPA). Compliance with those standards is assured by extensive testing in both the plant and throughout the complete water distribution system.
