Fourteen gallons of water per person is the suggested amount to store for a 2 week emergency situation. One thing to note is that this amount is enough for sustenance purposes only, 2 qts. for drinking and 2 qts. for cleaning and bathing purposes a day. When you consider that a person normally uses in excess of 140 gallons of water per day for drinking, bathing, laundry, dishes, watering lawns, etc. This is not a lot of water. If you have the room to store more you probably will want to do so.
