Most people could live a while without food as long as they have water. Stocking water reserves and learning how to purify contaminated water should be among your top priorities in preparing for an emergency. Store a total of at least one gallon per person, per day. This is a good estimate, although everyone s needs will differ, depending upon age, physical condition, activity, diet and climate. A normally active person needs to drink at least two quarts of water each day.
Hot environments can double that amount.
Children, nursing mothers and ill people will need more. You can minimize the amount of water your body needs by reducing activity and staying cool. You will need additional water for food preparation and hygiene. Storing Emergency Water Supplies Plastic, glass, fiberglass or enamel-lined metal containers are suitable for storing water supplies. Intact, durable plastic containers, such as soft drink bottles or those you purchase water in, are best.
