Fire water mains of a propritary large development shall serve multiple sprinklered buildings spaced well apart. Envision an industrial plant, an airport or a university campus including laboratories. The fire water mains shall also serve fire brigade hydrants.
In such cases we comply with a number of standards within NFPA (such as 1, 13, 24, 14, 101 and the occupancy specific standards) or similar. Add to this national regulations. Add to this hose allowance. Even add to this stakeholder demand to cope with two simultaneous fires. In complying to all requirements, water demand tends to increase by method of addition to seemingly unrealistic proportion. Each standard incorporate a kind of safety factor, so in lack of a systematic approach (like probability risk analysis) water demand is unduly increased. Any suggestion to a guide or a standard that addresses this? Any experience on determining the demand at such large proprietary fire water mains? I am not asking about the water mains design. My concern is assessment of water demand only.
