ADWR regulates all groundwater wells in Arizona. Well regulations are vital to the proper management and protection of our groundwater. Well construction standards help prevent contamination of your well and the surrounding groundwater.
A domestic well equipped to pump 35 gallons per minute or less may be constructed in many areas of Arizona to serve water for any uses related to the supply, service and activities of households and private residences.
