The Arizona Department of Water Resources (ADWR) Assured and Adequate Water Supply programs were created to address the problem of limited groundwater supplies in Arizona. Both the Assured and Adequate Water Supply programs evaluate the availability of a 100-year water supply considering current and committed demand, as well as growth projections.
Prospective homebuyers should investigate water availability before purchasing real property. The Arizona Department of Water Resources is your official source to investigating water availability and to learn more about groundwater supplies.
Information and maps of Active Management Areas can be found on the Arizona Department of Water Resources website.
