Agreed water can be a great revenue generator. Had a utility vault with with (2) 2000kw pad mounts in it, used to tie in to basement of 2 buildings that had just been demoed, when they filled in the basements with dirt they didn't water proof the walls exteriors. Not to mention the slope of the site was draining all the water to the vault. Little sump pump didn't have a chance of keeping up. Neither transformer blew and both the 12470 bushings and the 480v blades all completely under water.
Owner made the GC replace both transformers and the 15kv feeders back to the switch. We lost money on the actual building because of this GC but we made a killing off their insurance company on this part.
