"Facing a changing climate, southwestern U.S. cities such as San Diego, Phoenix, and Las Vegas have embraced a host of innovative strategies for conserving and sourcing water, providing these metropolitan areas with ample water supplies to support their growing populations."
"In the rolling hills around San Diego and its suburbs, the rumble of bulldozers and the whine of power saws fill the air as a slew of new homes and apartments rise up. The region is booming, its population growing at a rate of about 1 percent a year.
This, in spite of the fact that Southern California, along with much of the West, is in the midst of what experts call a megadrought that some believe may not be a temporary, one-off occurrence, but a recurring event or even a climate change-driven permanent “aridification” of the West. The drought is so bad that last year federal officials ordered cuts to water provided to the region by the Colorado River for the first time in history.
Water officials in San Diego, though, say they are not worried. “We have sufficient supplies now and in the future,” said Sandra Kerl, general manager of the San Diego Water Authority. “We recently did a stress test and we are good until 2045” and even beyond.
San Diego is not alone. While the public image may be that booming southwestern cities such as San Diego, Phoenix, Las Vegas, and Albuquerque are on the verge of a climate apocalypse, many experts agree that these metropolitan areas have enough of a water cushion to not only survive, but continue to grow into the surrounding desert for the foreseeable future, even during the worst drought in 1,200 years. Regardless of what the future holds, the search for water savings and more supply has so far been largely successful."
