How a California Desalination Plant Could Ease Water Shortages on the Colorado River

With desert cities like Phoenix and Tucson bracing for their allotments of Colorado River water to be slashed dramatically, San Diego County’s water agency could for the first time sell some of its water to other states by drawing on its ample supplies from the nation’s largest desalination plant.

The San Diego County Water Authority’s board unanimously approved an initial agreement last week to consider selling some of its water to Arizona and Nevada, where cities that depend on the over-tapped Colorado River are expected to face substantial cuts in water supplies.
