It's like sprinkler hydraulics in that the size of the piping may have to be calculated, which is based on the available flow and pressure from whatever water supply you're starting with. Usually, and I emphasize usually but not always, a 6-inch lateral is adequate for a single hydrant but not if its 450 feet long.

I see where this particular project requires 1500 gpm @ 20 psi for 2 hours, what is needed to translate that into required underground/tap size?
