Weird article.<p>It talks about why toilet-to-tap is technically feasible, but not (specifically) why we &quot;need&quot; to adopt it, let alone whether it&#x27;s inevitable.  In Perth, or anywhere else.  (Yes, it mentions general factors.  But at no point does it make a logical case to support what it says in its headline).<p>BTW, a prediction: in the same way that corporations have strenuously (and in some cases, successfully) lobbied for prohibitions on labeling GMO-derived foods as such, or rGBH-derived milk as such -- one day we&#x27;ll equal if not more energy put into efforts against against labeling toilet-derived drinking water as... exactly what it is.<p>And I&#x27;m sure one day, these efforts will ultimately succeed, also.
