    And what to do with the waste water from the reverse osmosis (now more contaminated than the input)? And who pays for the water wasted?

      it goes to the sewer system which needs to be able to take care of things anyway. The amount of waste water through a RO system insignificant - your toilet flushing needs will use more water than your RO drinking water needs. (a typical low flush toilet, though some camping toilets use less)

        Haven’t looked at them in a while, but I know the aquarium ro filters produce 1:1 waste: water. Could certainly be more efficient now, but I haven’t researched in a while

          there are different systems with different efficiency ratings. However even the worst don’t use much water - you don’t drink much water in a day.
