Just pure speculation, there appeared to be multiple chillers that serve WL and they can probably run with one down.
You can get portable chillers delivered pretty quickly they’re mounted on trucks and fully mobile. They can runoff portable generators and all you’d have to do is pipe into the existing system..
Even a broken, chilled water pipe, can be routed above ground with temporary piping.
All these issues are not uncommon, but It’s not an instantaneous fix, and it shouldn’t take more than a day or two.
If this is going on for a third or fourth day, there’s something much more serious going on.
