2025 Arroyo Published on Expanding Water Supplies
The WRRC is pleased to announce publication of the 2025 Arroyo: Expanding and Diversifying Arizona’s Water Portfolio. This year’s Arroyo describes the many ways Arizona is exploring to develop “new” water sources for a secure, sustainable supply. After outlining current water supply challenges, it focuses on four broad strategies: treating water, capturing water, transporting water, and exchanging water. Specific initiatives detailed include advanced water purification, desalination, solar powered water filtration, modifications to dams and their operating rules, water harvesting, watershed management, groundwater recharge, pipeline projects, leasing water, and payments by some water users for others to use less water. Drawing from presentations given at the WRRC 2024 Annual Conference, Implementing Water Solutions Through Partnerships, this Arroyo offers a hopeful message based on evidence of progress made through the combined efforts of many.
