Hi

Considering crucial situation of water resources, I assume it is important to recycle water for non-potable uses. On the other hand, as you may know, a considerable amount of money are being spent on providing a high quality potable water, which majority of it won't be used for drinking. 

To wrap up, I think it is necessary to separate drinking water consumptions from the other uses of water. 

I have seen some standards and guidlnes in this regard, and I will email them to you. I hope it could be useful.
