In a home fallout shelter, however, you and your family would be largely on your own. You would have to take care of yourselves, solve your own problems, make your own living arrangements, subsist on the supplies you had previously stocked, and find out for yourself (probably by listening to the radio) when it was safe to leave shelter. In this situation, one of your most important tasks would be to manage your water and food supplies, and maintain sanitation. The following guidance is intended to help you do this.
Care and Use of Water Supplies
The average person in a shelter would need at least 1 quart of water or other liquids per day to drink, but more would be useful (to allow some for washing, etc.). Therefore a rationing plan might be required in your home shelter, so as to make your available liquids last for 14 days. (Many communities may continue to have potable water available, and families could relax their rationing plans.)
In addition to water stored in containers, there is usually other water available in most homes that is drinkable, such as:
--Water and other liquids normally found in the kitchen, including ice cubes, milk, soft drinks, and fruit and vegetable juices.
--Water (20 to 60 gallons) in the hot water tank.
--Water in the flush tanks (not the bowls) of home toilets.
