Power Plant
Looks like backup batteries. It can't be backup for the town. I think it's probably battery power for the lights and electronic systems in case there is an outage...
These generators are beasts. You've gotta wear 2 layers of hearing protection to go in and the whole place vibrates from those suckers...
Looks like heat exchangers...
Lots of meters and buttons to push...
Water Treatment Plant
Apparently they desalinate 50,000 gallons of sea water a day for town use. Tastes delicioussss
I don't know much about any of this stuff. I'm pretty sure the white tubes are part of the desalination system...
These are all carbon dioxide cylinders. Since they're all painted red and connected into a big manifold my guess is that it's part of the fire suppression system. The water treatment plant is pretty important since we only have one. I can't imagine how bad things would get if that place burned down. We'd probably be melting snow for drinking water, while we waited for the weather to clear enough to evacuate, assuming that could even be done at all. Lets just hope those little red bottles do their job if God forbid they're ever needed!
This looks like it might be where they do tests on the water to make sure it's clean and all that...
