Precisely. I worked for a water utility, in Australia, and this was the issue.<p>&quot;What&#x27;s in waste water?&quot; People would answer, &quot;E coli, food scraps, garbage&quot;.<p>Okay, so here&#x27;s tap water. Show them lab samples.<p>Do the same with our &#x27;grey water&#x27; (after processing). Lower impurities.<p>People still wouldn&#x27;t touch it. We could use it for things like golf courses, etc, which lessened the load, to be sure. But still.
