Herb Guenther, director of the Arizona Department of Water Resources, has often said that the era of cheap water in Arizona is over. It's a wise sentiment, and I think that it's high time the era of cheap water in Arizona was over, but is it really? Have Arizonan water companies really changed the way they price their water for retail consumption? Have consumers really changed the way they use it? We're beginning to make some progress by implementing more increasing block rate structures. With these rates, as usage hits a specified threshold, the per unit price of water rises for the next block of water usage.
