This is what’s happening in California as the state tries to cope with a record-breaking drought that is now in its fourth year.Some state officials are proposing that the Golden State implement a water-recycling policy that is known as “direct potable reuse.”Direct potable reuse involves taking sewer water, treating it through a three-step process and then pumping it directly back into the water supply so that it can be used for drinking. In effect, human beings would do the same thing that the pet dogs do when they lap water from a commode. Critics of the concept refer to it somewhat distastefully as “toilet to tap.”It isn’t just California, either.
