You'd THINK this goes without saying.  Apparently, it does not.  The city of Chandler, Arizona had to put signs up around their City Hall telling people NOT to drink the water out of their toilets and urinals.

Gray water is a term for reused wastewater.  In other words, sewage water that hasn't been treated, processed, or made safe for drinking.  Using gray water in public toilets is one of the environmental measures the city is trying to take.

Craig Younger is a spokesman for the city of Chandler.  He says they didn't post the signs because they've had problems with people drinking out of the toilets . . . they posted them because they HAD to.

 He says the city needed to get a building code variance to use the gray water in their toilets . . . and as part of the deal, they were required to post the signs.
