SOO 4.02 states: “All work and materials will be based on NFPA 22 Standard requirement for the design, construction, installation, and maintenance of tanks and accessory equipment that supply water for fire protection.” NFPA 22 does not appear to require a water level indicator.

Will this be allowable in the new design of tank and fill piping? If so, will the new and existing water line be required to be insulated and jacketed above ground?

Answer: The existing tanks will remain in service until the new system is operational, so new piping and valve shall be installed. The contractor shall refer to SOO 4.03 and 4.04.03

21. SOO 4.04.02 states: “Contractor shall install one (1), new 40,000 gallon (minimum) steel water storage tank…”. Is this specification intended to mean 40,000 gallons of usable water?
