In a crisis, you need to make sure you have enough water to drink, for hygiene, and for cooking. Normally, most people need to drink at least two quarts of water each day. If you have pets, you need to ensure that you allow for 1 quart per day for each dog or cat. Remember, the more water you stockpile, the better off you are in an emergency.
In addition to water, stocking emergency powdered and dehydrated milk can add much-needed protein and nutrients. Drinking powders can help relieve boredom and encourage additional hydration, especially needed when your body is under stress.
