Using recycled water is a necessity that we will all have to come to terms with in the future. Drinking it probably will not be necessary. Most of the drinking water we use is flushed, poured or washed down the drain and has very little to do with being consumed by mouth. A simple rainwater tank on most residences will produce enough drinking water to serve the needs of the occupants. Bottled water (whatever you think of the marketing of it) can also be used to serve the drinking needs of most people.
I have found that the installation of a filter on our kitchen water supply has significantly enhanced the palatability of our water, so I do not think that our current water supply is all that "pure".
So, in short, most of the water we use is not consumed by drinking and even if it is our current water is not as pristine as we might like to think it is.
Bottoms up,
David.
