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. :) DJ

Some facilities (Terremark comes to mind) offer chilled water from the local power company so you don't need to have your own chillers. What is the fault tolerance requirement for a power-company chiller plant though?
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.
