People with far more knowledge about this: when a data center “uses” water, what happens to it? Does the act of cooling servers with water “use up” the water or can it be cycled back into the water system? And if it is theoretically possible for it to be cycled back into the system as opposed to being dumped like sewer water, why isn’t it?

I have a lifetime subscription to Filen that I got a year or so ago and have been very happy with, much nicer than Proton Drive in my experience.
