Water is literally the easiest thing to recycle.

  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. source: veolia (world leader in water services).

    Do 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).

      "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.

    Whether 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.
