According to the American Red Cross and the FDA the average person consumes a minimum of 1 gallon of water per day. Many experts argue that actual water usage is closer to 2-3 gallons, per person, per day. Given this information, we strongly recommend storing no less than 3 gallons, per person, per day, and no less than a two-week supply. For those who care about personal hygiene we suggest rounding-up your water needs rather than rounding-down. Also, don't forget the needs of your pets and garden.
