I've never truly understood water cooling in computer setups, but my thought had always been that it doesn't utilise continually running water (ie like when having a shower), but by having water tanks filled, then pumping the water in/out/across the heatsinks; ergo, if the Utah data centre had a tank holding a few gigalitres, then they aren't reliant upon whether the mains is turned on of off, as they have the water already on site.

(Someone please correct me if I'm wrong)

Even if they shut the water off, it's not a stretch of the imagination that water tanks would be built, and water carrying helicopters are chartered to fly in the required h2o.
