Dear Dr. Sharma,
I would like to present a very simple fact pertaining to the nature of the planet on which we live, and I leave behind any comment about the validity of your question.
Let us consider any human activity whether it is commercial or residential, if you discharge your treated wastewater on the soil surface to go underground in your backward, then you dig a water well about 50 m away from your treated wastewater discharge point, you will be able to get potable water needing some filtration and probably some exposition to UV. (Even some local engineering codes in the US, are allowing this design).
The Lord in His Kindness provided us with this capacity, as He Did so many marvellous things for us....???
