About 5% of Arizona’s population depends on private wells for fresh water and more than 40% of our annual water use comes from Arizona’s aquifers. Following a brief introduction to regulations, requirements and equipment used for drilling a private well in Arizona, this video presents the geologic origins of Arizona’s aquifer materials with illustrations and pictures of AZ aquifers. Finally, aquifers are ranked by their ability to store and produce water.

Private well owners should also be familiar with above-ground well components for maintenance and emergency purposes. This video describes well components such as bladder tanks and pressure controls, their common locations and how to inspect them.

After an introduction to the regulatory requirements and forms needed to drill or deepen a private well in AZ, this video provides detailed descriptions of the well drilling process with close up views of a drill rig, well casing placement, and pump removal and replacement steps.

Arizona private well owners are responsible for their well water quality. This video shows where to collect water samples and describes the sample collection process in detail for the analysis of contaminants to insure unbiased results.
