Good job.

I've had to deal with assorted water problems, thankfully not 
recently.  Some lessons were learned.  These water problems were 
indirectly or directly caused by firefighting.

1. When the data/comm center is on a bottom floor, consider floor drains at
   the time of installation. Might want emergency access to pumps, or even
   wet-dry shop vacs.

2. We had a repeated problem in several moderate-rise buildings where there
   were fairly frequent, although small, fires on upper floors. Water, of
   course, runs downhill.  Some things done (this was the US Senate offsite
   computer center)

   a. Put waterproof gaskets on the emergency stairs that had entrances
      from the control room.
   b. When it happened often enough, we mounted rolled-up plastic tarps on
      rollers suspended from the ceiling, with a good solid handle dangling
      down on a rope. During the peak problem period, we'd hear an alarm,
      pull the tarps over the equipment, and then do a fast power-down (not
      necessarily emergency pull--this depended on heat buildup). The tarps
      were a few inches over the top of the racks, to leave some room for
      emergency airflow during cooldown.

3. Consider putting data centers not in the ground floor on the basement,
   but not too high either.  Sean, I believe, knows the specific NFPA rule,
   but IIRC you can't have a UPS with acid electrolyte above the third floor.
   So, you can put a data center on the 2nd floor and both allow the UPS
   and have a place for the water to drain.
