If it's for rainwater what's the hazard you'd be protecting? Would you protect a retention pond? Not trying to be snarky but just trying to post some parallels for thought.
It's outside, non-combustible, so no, I wouldn't propose any type of internal sprinklers. Now if it was right up against a building and it would contain appreciable amounts of non-diluted combustible or flammable chemicals due to a spill within the building there may be cause to look at some exposure protection for the building but that would take a lot more information and analysis. We've used this approach on many projects where secondary containment was required Craig L.

The building is a laboratory. So there are hazardous substances. I still need to check what gets collected in the pit. The maintenance guy told me it is for storing rain water. Assuming it is rain water (till I check it out) would this pit have to be sprinklered? If it is for containment of spills of chemicals, would it have to be sprinklered then?

Is this "secondary containment" per IFC/IBC?

See NFPA 13/2010 8.5.5.3.1. Note that nothing is said about what's under the grated floor being relevant. Earlier versions have, if not exact, similar language.
