Yes that is right. I was also thinking since those real estate companies provide 24 hour water supply using bore water within their area, if that is feasible then why doesnt the Nepal government provide 24 hour water supply using bore water also.

I also wanted to know if a study has been done regarding potential danger of same. I find it hard to believe that real estate companies can provide 24 hour water supply using bore water and having their own treatment plant.

But you are right hard to make it illegal.
