Every individual situation is different and so a one size fits all water plan is not going to work. So, in this article I will go through different ideas to help get you thinking about your water storage needs.
We'll start by looking at the estimated amount of water per day that is required per person. In doing my initial research, I've seen a minimum of one gallon per day per person, to up to 3 gallons per day per person being talked about on various prepper websites. Well if you are storing water for more than a few days worth, that can amount to a huge difference in the long term. So I went looking for the sources of these numbers.
What I found was that the one gallon per day is a number taken from the U.S. Army Corps of Engineers (USACE) an emergency distribution number for basic survival purposes to keep people alive. It in no way represents a realistic long term survival number. So I kept looking to find some more information.
