Is it a high-rise building with a 30 minute automatic water supply? Or is it a low-rise or mid-rise with a manual standpipe system? If the latter, where is the water coming from for the FD to pump into the standpipe?

There will also be standpipes in the building with 2 1/2" hose valves.

If there are hydrants downstream of the tank, are you going to have to meet site fire flow requirements per the IFC? If you have to do that, your tank size is going to be huge!
