Any reference of it w.r.t NFPA code
Is it according to point No 7.2.9.1 mentioned in NFPA 22??

It's based on the last three chemical plants I've been in charge where Fire fighting system were designed based on NFPA XX and audited by Insurance.

What you are refering is the resplenishment of the tank after an event .Your tank must be "always" full of water in case .

Here you need to talk to the fire fighting bureau where the plant is or will be located to ensure the compliance with regulations.
