would be nice if true but turning waste water into drinking water is actually among the most difficult things and requires a very significant amount of high tech to achieve.
drinking water is a scarce resource and around 98% of use is not drinking but turning it into waste water and sewage.

- tomp 8y agoDo you have an actual source (i.e. a document/web page)? I always thought it's just a matter of distilling it, filtering it, and/or doing some reverse osmosis (which is indeed technologically non-trivial, but it's quite established tech).
- roel_v 8y ago"Just" a matter of distilling it? Have you ever looked at the sheer amount of water entering and leaving a water cleaning plant? It's not a matter of having the technology, but of doing it at scale.
- adrianN 8y agoWhether drinking water is a scarce resource or not depends on where you life. In many parts of the world saving water makes zero sense, because the sewers need a certain amount of water to prevent clogging. If people save too much the water company has to flush the pipes.
