It highly depends on every data center, but it is very likely that they do use municipal water for cooling. Mainting a Reservoir is extremely expensive for the amount of thermal mass it requires, these things kick off HEAT.

I don't know why they aren't using reclaimed water from treatment plants. I don't see why potable water is necessary as long as the substitute isn't corrosive, but I might be missing something here.

You'd have to get the gray water in, and it's more efficient to just continue treating it and using the municipal water system.
