I have been considering a emergency water storage system for my home. My current thoughts are to "plumb in" a 50 gal food grade plastic barrel into my basment water line feeding a exterior faucet. The occasional use of the faucet should keep the water fresh and a valve above would allow the source to be cut off if needed. A faucet would also be placed in the barrel at its low point to allow direct access from the interior of the basement. Any thoughts or comments on this idea would be welcome.
