I don't know of any restrictions in code or standards that would preclude a "central plant" water supply, and I think the AHJ is over-reaching in his interpretation of separate. NFPA 13 and 14 speak to connection of systems to adequate water supplies, which can take any one of a number of forms. Those can even be a combination elements - tanks, pumps, wells - that collectively make up an adequate water supply. The "separate and complete stand-alone fire suppression system" is still to be furnished: separate service from the point of connection to the water supply, separate control valve(s) and FDC(s), separate riser, separate local alarm, separate supervisory system, separate monitoring address, etc. So long as the existing automatic water supply is adequate to meet whatever demands are created in the new building, there's no prohibition against using it.

Local AHJ states IBC requires a separate complete stand alone fire suppression system thus requiring the owner to provide a new fire pump and city water connection for the building. Has any one run across this IBC requirement or is the AHJ incorrect in his statement?
