Jim,
An inexpensive way to store a couple hundred gallons of water is simply in install an extra water heater. Electrics are cheap (a couple bucks a gallon), and don’t even need to be electrically connected. The fresh water continually flows through, and can be drained down for short-term needs during an interruption. If installing in new construction, it’s even easier, and an electrical connection means that you have hot water in the event of a natural gas interruption. Plumbing and valving should ensure that the tank can be gravity drained, and that either heater may be taken out of the loop as needed. Joel Skousen’s book The Secure Home is a good reference for a practical plumbing/valve layout for this sort of installation. – Mr. Bravo
