From Toilet to Tap - a New Source of Drinking Water

As climate change brings rising temperatures, drinking water is becoming a coveted natural resource. As Lake Arrowhead dries up in Texas, residents turn to waste water as a new source of the precious liquid. The city installed a pipeline from the waste plant to a water treatment facility to be cleaned. Citizens are enthusiastic about the project, but are always thinking about what they will do if the water runs out; a scenario that has been predicted if there is no significant rainfall in the next two years.
