Ok and? This wouldn’t be an issue if google et al would just share the numbers instead of hiding behind NDAs and whatever else.
Not sure why this is being downvoted. If you noticeably distort the local economy then people are naturally going to want to know what resources you're consuming.

I think all data centers and other industrial concerns above a certain size should have to publish that.
Are you sure? People think water for data centers is "consumed", like the output is sewage or something. Giving those people concrete numbers is not gonna change such misconceptions (and that's assuming they look at such numbers in reasonable relative terms in the first place).
