Which of the following is a common use of exempt wells in Arizona?

Exempt wells in Arizona are typically utilized for domestic purposes, which includes household water supply. These wells are designed to provide a reasonable amount of water for individual households without the need for a permit from the Arizona Department of Water Resources, as long as the usage does not exceed certain limits—usually up to 35 gallons per minute and for non-exempt small irrigation uses.

This exception facilitates access to water for residential use, reflecting the state’s acknowledgment of the importance of ensuring that individuals can meet their basic water needs easily. The regulations regarding exempt wells thus aim to balance the necessity of personal water supply against broader conservation and water management goals.

In contrast, uses such as commercial agriculture irrigation, industrial manufacturing, or public utility water supplies generally require more stringent permitting and are associated with larger-scale water use that often draws from the regulated water supply to ensure sustainable management of Arizona's water resources.
