It's not like an adequate water supply It's a connection through which the fire department can pump "supplemental water" into the sprinkler system. How much water does it take to supplement the supply?

Just because it is the same piece of equipment doesn't mean that they have the same objectives or levels of criticality. Try submitting a proposal next cycle showing the friction loss and try to change it. WHat is the loss at 250 gpm and 500 gpm?
