If you DON’T have hydrants downstream, do you have a standpipe with hose connections and an automatic supply? I’m guessing not. If not then you don’t need the hose allowance (since there’s no place for hoses to be used).

If so, you could be looking at 180k gallons and up.

Worst case for this particular building would be OH-2. (.2/1500 = 300gpm + 250 hose. 550gpm for a minimum of 60 minutes = 33,000 gallons). Per NFPA22 (2013) 5.1.3.1 round it up to 40,000 gallons. Does that sound about right? Brian Harris, CET BVS Systems Inc.
