You would just shift the costs away from maintaining pipes to treating massive amounts of water that would never get used by anybody.

And you will still have to maintain the pipes. Your solution would reduce costs per mile, but you still have a lot of mileage to maintain with a shrinking population.

I would believe that there are areas where something like this, perhaps for groundwater recharge, wouldn’t be totally crazy.
