HESPERIA, CA - JULY 28: Sprinklers water the lawns of a new housing development July 28, 2005 in Hesperia, California. California's demand for water will jump by 40 percent over the next 25 years according to a study released this week by the Public Policy Institute of California. Half of all the water used by inland homeowners, where growth is booming, goes to irrigating yards, compared to one third or less in the cooler coastal regions. (Photo by David McNew/Getty Images)
