GROUNDWATER USE    Water use figure

  • From 1979 to 2005, total water use in Sheboygan County has increased from about 20.0 million gallons per day to about 25.4 million gallons per day.*
  • The increase in total water use over this period is due to increases in all use categories except industrial which shows a substantial decline until 2000 after whicn it increased through 2005. Public use and losses and commercial uses declined after 2000.

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