They don’t do that for a large portion of the water - they dance around that with weasel words (like ‘return to the environment’), aka evaporate. You can see they are constantly weaseling out of giving anything concrete that someone could accuse them of lying, or could use to point out the actual impacts, and stating ‘a lot’ can be reclaimed from evaporation for instance in the building - while ignoring cooling, which is evaporative at these scales [https://www.google.com/amp/s/www.cnbc.com/amp/2021/06/04/why...]

It’s pretty typical corporate green washing of a real problem that other folks will end up having in diffuse, hard to pin on them ways, that with some nudging on the right officials will never be pinned on them. In my experience, anyway.
