Bangalore has a problem: It is running out of water, fast. Cities all over the world, from those in the American West to nearly every major Indian metropolis, have been struggling with drought and water deficits in recent years. But Bangalore is an extreme case. Last summer, a professor from the Indian Institute of Science declared that the city will be unlivable by 2020. He later backed off his prediction of the exact time of death—but even so, says P. N. Ravindra, an official at the Bangalore Water Supply and Sewerage Board, “the projections are relatively correct. Our groundwater levels are approaching zero.”
