Which is considered an exempt domestic well?

The correct answer relates to the regulations governing domestic wells in Arizona. A domestic well is typically defined by its purpose and capacity for personal use. Specifically, a domestic well with a maximum pumping capacity of 35 gallons per minute is recognized as exempt under Arizona law. This exemption allows homeowners to utilize the water without needing a formal permit, as long as the usage complies with the specified limits.

This particular definition serves to ensure that small-scale water withdrawals for personal use do not significantly impact the region's water supply. Although wells with larger pumping capacities exist, they may not qualify for the same exemptions, thereby requiring more regulatory oversight. The focus here is on making household water access manageable and sustainable without overly burdensome regulations for those within the established capacity limits.
