A remote project site does not have any water utility available.
Under the latest edition of NFPA 22 (2018 Edition of Water Tanks for Private Fire Protection, Section 4.1.1), the "size... of tanks shall be determined by the required fire flow and duration for the attached fire protection system(s) and the pressures required."
Is this implying that the site fire flow for firefighting operation should be included as part of the storage volume for the water storage tank?
For this project the sprinkler system's required water supply would be about 40,000 gallons, while water storage for site fire flow would be well over 240,000 gallons under IFC fire flow or 140,000 gallons under NFPA 1142. Prior versions of NFPA 22 required "the size... of the tank shall be determined by conditions at each individual property after due consideration of all factors involved."
