If there are separate feeds from two different municipal service zones that are sufficiently remote and permit concurrent maintainability of the underground supply, there may be a benefit to this. We have been working at a large campus that includes two data centers, each with redundant feeds. Obviously a very high value asset. This is an FM insured facility, but this may not necessarily have been their recommendation when the buildings were constructed (circa 1990).
The secondary feed could be from a separate municipal zones, from a campus tank/pump, or from an elevated tank. The intent is to eliminate single points of failure the originate outside the facility. I think you need to know more about what is upstream of the facility before you can draw a conclusion.

What I mean is two parallel run-ins, each with a PIV going to serve the same sprinkler riser. I have never done this before and I know FM (insured) and NFPA do not advocate this kind of arrangement. Has this ever been done before and if so why? I am trying to respond that I don't think it is a worth while investment to "ensure" continuous water supply.
