New York Times: "Safe storage of water? Go underground!"
AUSTIN, TEXAS - When cities store water for future use, they often use large lakes created by damming rivers. Now, experts are urging cities to build reservoirs below the ground, where the water cannot evaporate and many of the difficulties associated with above-ground water storage are avoided. "It just makes so much more sense," said Jim Lester, president of the Houston Advanced Research Center, a nonprofit research group. Among other advantages, he said, underground reservoirs are cheaper than their above-ground counterparts.
