Reclaimed Water
• Always Available
• Arizona’s only Growing Water Supply

• Consumer Protection - Demonstrate sustainable growth
– Physical & legal available water supply for 100 years
• Site-specific determination (Certificate of AWS)
– Project developments’ water demands

Opportunities
• Regional Planning Organizations
• Non-Indian Agricultural (NIA) Priority• Non-Indian Agricultural (NIA) Priority CAP water
• Reclaimed water/water reuse
• Groundwater in storage (potable, poor quality & brackish supplies)

poor quality & brackish supplies)
Opportunities
• Water supplies developed . . .
– revised watershed managementrevised watershed management practices
– weather modification
– large-scale or macro rainwater harvesting/storm water capture
22
harvesting/storm water capture
• Import or exchange of new water supplies (e.g., ocean desalination)

Questions for the near and long-term:Answers
– How will our water be used?
– Where will it come from?Statewide, but 85% in Maricopa, Pinal, and Pima
Groundwater, Surface Water, Recycling, and Beyond– When will we run out?
We won’t . . . Unless we decide not to plan for or invest in our water resources
and infrastructure
