“Everyone will feel pain” was the mantra emanating from supporters of Arizona’s drought plan for the Colorado River as it wound through the Legislature. It is true that under the plan, now embedded in state law, the major water users served by the $4 billion Central Arizona Project — cities, tribes and farms — will all take a hit. But some users will be hurt more, and some will be hurt sooner, than others. Cities will lose the least amount of water and those cuts will not be noticed by their customers.
