There's going to be a lot of things that don't work, and a few things that do work. But at least they'll have substantial power available to operate big pumps that can move a LOT of water. And with any luck, they'll be able to use some of the existing piping in the damaged structures.
Hopefully the few things that work will be the pumps and valves. A couple of sensors would be nice but I'd settle for the pumps and valves. :-}
