Revisiting 'toilet to tap'

Los Angeles' water supplies are getting lower. The once-desolate Owens River Valley burst into flower this year because the Department of Water and Power brought less water to the city. Other states are increasing the amount of water they are able to tap from the Colorado River, L.A.'s primary source of water. And this has been the city's driest year on record. In response, Mayor Antonio Villaraigosa has called for greater water conservation to help meet future needs.
