How are hydrants and standpipes connected to the overall water supply network addressed in NFPA 13E?

• A. As a separate topic unrelated to the water supply.
• B. Only when there is a known shortage.
• C. As part of the water supply assessment, ensuring adequate pressure and flow to meet protection goals without compromising the public supply.
• D. Only for new buildings.

Answer: (C)

Hydrants and standpipes are treated as part of the building’s water supply assessment under NFPA 13E, not as separate or isolated components. The standard requires evaluating whether the public water supply can deliver the required pressure and fire-flow to meet protection goals without overloading or compromising service to the broader community. This means checking the available supply, potential demand from the sprinkler and standpipe system, and any need for on-site storage, pumping, or alternative sources to ensure reliable operation during a fire while maintaining adequate pressure for other users. The goal is to design and evaluate the system so fire protection demands are met without negatively impacting the public water system, reflecting the integrated approach NFPA 13E promotes for existing occupancy protection.
