groundwater pumping; measuring; reporting

SB 1249 requires most groundwater users in Arizona's designated active management areas and irrigation non-expansion zones to install approved measuring devices and submit annual reports on their water use. It exempts small-scale users (with ≤10 acre-feet of annual withdrawal) and specific agricultural operations, such as those using water solely on ≤10 contiguous irrigated acres without large-scale farming. The bill clarifies reporting obligations for landowners, farmers, and water transporters while maintaining existing exemptions for certain exempt wells and municipal users. These changes aim to standardize groundwater monitoring and reporting without altering water rights or usage limits.
