I feel like you'd want the monitoring station not at the top level entrypoint where someone could break in then monitor your whole complex and the outside.

Feels like that should be closer to the panic/shelter room.

Also like someone else called out, you don't want your generators on the bottom floor. If you do something like that, you should dig another level below that's purely for drainage/runoff like a giant water reservoir. You can put a sump pump there to pump it all back up to the surface if you'd like, but you need some way to both collect and excrete water or drainage of some sort.

I don't see room for a water processing plant, so I think you're dealing only with pre-treated stored water in this system. That's the last thing that needs to be solved for. There needs to be some way to recover water if you want this to be a closed system.
