December 5, 2008 AMC/CSA Meeting Investigation of Binational Desalination for the Benefit of Arizona and Sonora Guy W. Carpenter, P.E. Project Manager guy.carpenter@hdrinc.com 1-602-522-4337
To pursue water management planning in the Arizona-Sonora region that emphasizes collaboration on programs for the advancement of economic, social, and environmental benefits of both states, and that arise from constructive solutions to shared water supply issues. Promover la planeación para la gestión del agua en la región Sonora-Arizona, que de énfasis a la colaboración sobre programas que promuevan los beneficios económicos, sociales, y ambientales entre los dos estados, y que surgen de soluciones constructivas relacionado a los asuntos compartidos sobre recursos hidráulicos. Arizona-Mexico Commission/Comision Sonora ArizonaWater Committee Mission Statement/Principio Básico

Fully allocated surface water Groundwater mining Future growth Access to the ocean 92% of water use is agriculture 5 MAF: 1.6M acres 6,167 hm3/año: 607,000 hectares 7% of water use is municipal and industrial (310,000 AFY: ~382 hm3/año) Fully allocated surface water Groundwater mining Future growth No access to ocean 68% of water use is agriculture 32% of water use is municipal and industrial Sonora Outlook Arizona Outlook
The Idea • Arizona and Sonora need more water to sustain economic growth • Need data to support developing a new supply of water for Arizona and Sonora • Timing: near- and long-term • Project • Ocean desalination • Brackish groundwater desalination
Not a New Idea • 1968: Nuclear power and water desalting plants for Southwest United States and Northwest Mexico • United States • Mexico • International Atomic Energy Agency • Project never advanced • Central Arizona Project authorized by Congress – although future supplies for augmentation still needed
AMC/CSA Provides the Opportunity • Expanding trade • Increasing economic development • Improving quality of life • Advancing environmental benefits • Preparing region for prolonged droughts
Project “Roadmap” • Background (Mexico Treaty, 1968 Study, etc.) • Description of study • Institutional framework (AZ, Sonora, U.S., and Mexico) • Water supplies (brackish groundwater and ocean) • Quantify water demands • Water production • Ocean (location, quality, technology, energy, costs) • Brackish GW (location, quality, technology, energy, costs)
Project “Roadmap” - Continued • Pipeline/canal alignments • Energy needs • Evaluation of alternatives
Both Studies Matter to Each Other • Success of Puerto Peñasco project planning and execution paves the way for future successes • Environmental, ocean, and policy impacts will influence future projects • Report findings should be consistent with one another • Working together to share information and ideas
Point of Reference • Ashkelon, Israel • 94,640 AFY, (117 hm3/año) • Capital cost • $250M (U.S.) • Production cost • $2.95/1000 gal ($0.78/m3) • Twice as big as largest previous plant • Globally, facilities will get bigger as water scarcity increases
Description of Actions to Date • Met with Peñasco, toured site • Attended initial desalination meeting in CA • Bouchard and HDR sharing information • Scenarios agreed upon • Draft investigation report prepared
Next Steps • Finalize the report • Discuss opportunities with Sonoran partners • Report back to AMC Spring 2009 • Future steps
