Groundwater Pumping Rules

This bill changes rules about measuring and reporting groundwater pumping in Arizona.

What This Bill Does

  • Requires people who pump groundwater from non-exempt wells to use approved water-measuring devices.
  • Exempts certain small-scale users from needing these devices if they withdraw less than ten acre-feet of water per year for specific uses.
  • Requires those who need to file annual reports about their groundwater usage to keep accurate records and submit them to the director.

Who It Names or Affects

  • People who pump groundwater from non-exempt wells in Arizona.
  • Irrigation districts that deliver water in active management areas.

Terms To Know

Nonexempt well
A well that is not exempt from the rules about measuring and reporting groundwater pumping.
Active Management Area (AMA)
