Water towers/tap water depend entirely on the amount of heat you are trying
to lose divided by the amount of space you have to lose it in. I am sure
some colos can just open the windows (if they have any) and run some fans.

We use chilled water (4-8 C) with regular tap water as a backup (separate
system). We have a water tower nearby, they say they can give us very high
probability that any one of these two will provide cooling at any given
time. As far as I know none of them have failed during the past two years
of operation.
