  1. Yuma’s Desalination Plant Caleb Bradshaw

  2. Desalination Plants in General • There are over 4,000 plants around the world • Approximately 800 are located in the U.S. (mostly in Florida, California, and other coastal states) • These plants combined can produce over 3,500 million gallons a day

  3. The 2 Main Desalination Processes • Electrodialysis • Uses a series of membranes • Has great electrical energy costs • Reverse Osmosis • Uses membranes • The most efficient means of desalination

  4. The Plant in Yuma • 1944- Mexico is allotted approximately 10% of the Colorado’s water • 1961- Welton farmer discover an underground saline aquifer, and proceed to drain it into the Gila River • Mexico’s crops cannot grow because the water is too salty

  5. To resolve the problem, the U.S. decides to build a plant in Yuma • A canal will be constructed to drain water from Welton to the Sea of Cortez until the plant is build

  6. Cienega de Santa Clara • The canal stopped short of the sea • Formed a 15,000 acre wetlands • Home to plants, animals, a small economy

  7. The Plant Finished • In 1992, the plant was completed ($250 million) • It only ran for 9 months before it was shut down • A canal draining water from Welton to the plant was flooded • The Cienega began to disappear

  8. Increasing Drought • In March, the plant was restarted at 10% • 90-day trial period • Trying to preserve the Cienega • Experimenting with desalting local ground water, and water from other locations • Time will tell
