Australians want recycled water :"'Cultural conventions, and most existing engineering systems, reflect the notion that what flows into the body and what flows out should be strictly separated, never the twain shall meet,' she said."
And thank heaven's for that. This is why we are civilised. There's a reason to separate the two and we have come a long way in terms of health since we did that. It's called hygiene and there is no guarantee treated sewage will be safe because unfortunately people are not to be trusted. Using recyled water for all sorts of other purposes is not a problem.
