This report from the Kyl Center for Water Policy and Arizona Water Innovation Initiative assesses the affordability of tap water rates of over 600 water providers – including publicly-owned systems, Tribal systems and privately-owned systems – to help Arizona communities balance considerations of affordability with their revenue needs. 

At the end of each month, the weather for that month is summarized in a publication from the Arizona State Climatologist office at ASU. It includes a narrative of the weather events across the state, graphs and maps including temperature and precipitation, as well as more specific data for Flagstaff, Phoenix and Tucson.

In 1995, the Arizona Legislature amended the state’s adjudication statutes and other statutes that underlie surface water rights in Arizona. What changes to Arizona’s adjudication and surface water statutes will survive Constitutional review? Learn more in this report from the Kyl Center for Water Policy.

Climate change is threatening water resources, increasing challenges to food and fiber production, and compromising human health in the Southwest through drought, wildfire, intense precipitation, sea level rise, and marine heatwaves. These changes are affecting ecosystems, infrastructure, agriculture, fisheries, and other economic sectors. 

In September 2023, the Babbitt Center, with our partners at the Arizona Water Innovation Initiative at ASU and Lincoln Institute’s Consortium for Scenario Planning, brought together farmers, ranchers, residents, city and county officials, and business leaders from the Sulphur Springs Valley to find common ground for their groundwater-dependent future.

Sustainable water management is essential in the Valley of the Sun, underpinning public health, economic vitality and quality of life in our desert cities. Underneath the Valley sits an enormous aquifer containing enough groundwater to fuel many generations of families and economic enterprises.

Access to safe, reliable, affordable drinking water is the foundation of public health, economic opportunity, and quality of life in any community.  Yet, significant challenges associated with providing and maintaining this access exist across Arizona, perhaps most acutely on Native American reservations and in small, physically isolated rural communities across the state. Learn more in this report from the Kyl Center for Water Policy and the Arizona Water Innovation Initiative.

As Central Arizona Project water becomes less available, central Arizona will be forced to rely more and more on groundwater, increasing the urgency to better manage it as a savings account for a drier future. The goal of safe-yield has been fundamental to the state's efforts to safeguard groundwater, but it is insufficient to ensure the long-term sustainability of groundwater supplies.

For nearly 40 years in its most urban areas, Arizona has prohibited the sale of subdivision lots that lack a 100- year assured water supply. But in 1993, the Legislature changed course and created a new path to show an assured water supply using groundwater–a non-renewable resource–with the promise that the groundwater would be replenished with surface water acquired after the fact.
