The Arizona Department of Water Resources (ADWR) has introduced a groundbreaking approach to water security in new residential developments. The Alternative Assured Water Supply Designation (ADAWS) program, filed with the Governor’s Regulatory Review Council on October 7, aims to change how water resources are managed for new housing projects across the state.
The initiative comes at a time when recent state groundwater models reveal a potential crisis. Parts of Pinal County haven’t approved new subdivisions in years due to water concerns, and existing housing inventory is dwindling. “As the supply of housing runs out, home prices will skyrocket. It’s that simple,” warns Pinal County Supervisor Stephen Miller.
Casa Grande Mayor Craig McFarland emphasizes the economic implications: “If adopted, we will once again be able to approve new workforce housing, hopefully in time to prevent the further escalation of housing costs.”
For developers and landowners, the new rules bring significant changes. Before breaking ground or selling a single home, they must now prove access to 100 years of sustainable water supply. Unlike previous regulations, the ADAWS program requires developers to utilize renewable water sources instead of relying on groundwater. Some cities are already adapting – Casa Grande plans to recharge its aquifer using treated effluent to support both existing and future developments.
The public has a chance to weigh in on these changes. The Governor’s Regulatory Review Council will review the rules at their October 29 study session, with a final decision expected on November 5. Residents can submit comments via email to gr**********@az***.gov or attend virtual meetings, with details available on the GRRC website.
The outcome of this initiative could set a new standard for water management in the American Southwest, where balancing growth with water security remains a persistent challenge.
