• Consumer Protection - Demonstrate sustainable growth

– Physical & legal available water supply for 100 years

• Site-specific determination (Certificate of AWS)

– Project developments’ water demands

• State makes regulatory determination

– Permit or modify application

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)

21

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)

Arizona’s Municipal Water Future

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
