​Meeting demand for the next 100 years

The State of Arizona has granted a "Designation of Assured Water Supply" to the City of Phoenix, affirming that at least 100 years of water is physically, legally and continuously available to serve the City's existing customers and additional growth. Currently, the City maintains access to supplies sufficient to demonstrate that demands at anticipated 2025​ levels can be met for more than 100 years. More information on Arizona's Assured Water Supply standard can be found in the 2011 Water Resources Plan.
