GROUNDWATER USE    Water use figure

  • From 1979 to 2005, total water use in Wood County has increased from about 100.0 million gallons per day to about 139.0 million gallons per day.*
  • The increase in total water use over this period is due almost entirely to an increase in industrial use.
  • The proportion of county water use supplied by groundwater has varied from about 8% to about 16% during the period 1979 to 2005.*
  • Water use in Wisconsin is generally estimated for the following categories:
    • Domestic
    • Livestock
    • Aquaculture
    • Irrigation
    • Industrial
    • Commercial
    • Public use and losses
    • Thermoelectric or mining*

* 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.



  • Wisconsin has abundant quantities of high-quality groundwater, but once groundwater is contaminated, it's very expensive and often not technically possible to clean.
