In Korea, I have seen huge 300 gallon tanks on the roofs in rural
areas. They have something similar to a toilets valve...as the water
level drops, the valve opens and lets in the city water to fill the
tank. If the city water stops, there is still three hundred gallons on
the roof in the tank. All the water pressure to the house is provided
by gravity since it is roof mounted. Really a simple idea. No batteries
or turning valves or nothing. You wouldnt even know if the city water
was off or not.

That's a very simple and interesting solution. Not sure it would pass
muster with the local US inspectors, but it's certainly got appeal for a
number of reasons. Thanks for the idea!
