Need suggestion on water purifiers

Hello experts,

First of all, let me thank you for the wonderful work you are doing here by providing your expert opinions.

Recently I tried to install purifiers for my borewell water and had contacted a few companies. But it turned out that the water contains TDS of 6000 and all the company representatives suggested that the domestic water purifiers are not feasible for this high range of TDS and I should install commercial purifiers costing 2 lakhs initially and 10% maintenance cost every year. My questions are:

  1. Is there no domestic water purifier at all which can purify this water?
  2. Is there cheaper commercial alternatives to get the water purified?
  3. Is the above suggested solution worth, or should I just drop plans for purification and go for buying water in tankers?

Please let me know your suggestions. Thank you in advance.
