OK, so your first reaction is going to be NO WAYYYY! — but you may be wrong. If you live in Orange County, California, or Fairfax County, Virginia, your water may well be going from toilet to tap, albeit via some filtration technology along the way. Kathy Chu reports on the increasing use of waste water in drinking systems in thirsty places around the world, for USA Today:
… “Water is going to be the oil of the 21st century,” predicts Bill Cooper, director of the Urban Water Research Center at the University of California-Irvine.
Clearly, something needs to be done. Roughly 884 million people — 1 of every 8 in the world — still lack access to safe drinking water, according to the World Health Organization and UNICEF. Meanwhile, water use has increased by more than twice the rate of the world’s population growth during the past century, United Nations data show.
