I’m not saying it is impossible to do or not a potentially sensible option in certain places, I am saying it is not going to be cheaper than tap water anywhere.
How does this work? If it’s a sensible option in certain places (those without access to tap water), how can tap water be cheaper? Why wouldn’t everybody just bring tap water to those places as well if it was cheaper?
It might still be more expensive but more resilient to other external factors such as embargoes, wars, whatever might influence delivery of other water sources. Cost isn’t the only factor to decide what technology or solution should be implemented.
