Can a commercial pool be used as the required secondary water supply to a high-rise sprinkler system?
The 2019 IBC/CBC Section 403.3.3 requires an automatic secondary water supply in certain seismic design categories. This is typically met by installing a dedicated tank that meets the minimum demand for 30 minutes.
I have a developer asking if they can run a feed line to their 100k +/- gallon commercial pool so it can serve this purpose.
Outside of the engineering challenges and value engineering their team must address, I'm wondering if this arrangement is even allowed. I cannot find anything in IBC/CBC, NFPA 24, NFPA 13, etc. that wouldn't allow this. Any help is appreciated.
