GROUNDWATER USE    Water use figure

  • From 1979 to 2005, total water use in Kenosha County has fluctuated from about 17.8 million gallons per day to 23.0 million gallons per day.*

    • Domestic
    • Livestock
    • Aquaculture
    • Irrigation
    • Industrial
    • Commercial
    • Public use and losses

* Thermoelectric and mining data are not considered in water-use tables or figures on this web site. Thermoelectric-power water use is the amount of water used in the process of generating thermoelectric power. The predominant use of water is as non-contact cooling water to condense the steam created to turn the turbines and generate electricity.
