This requirement is in place to ensure sustainable water use and to protect the aquifers, which are vital for the long-term water supply in the state.

In this context, developers must provide a "100-year assurance," which includes a water supply report demonstrating that sufficient water is legally and physically available. This assessment is crucial due to the increasing demands on water resources and the need to balance development with conservation practices in areas where water is a limited resource. The 100-year supply requirement reflects Arizona's proactive stance in water resource management, ensuring that as new developments occur, they do not contribute to over-extraction or depletion of groundwater supplies.
