Water

Water, it’s something everyone needs and can’t live without. No matter what the situation, having clean water on hand is a must. According to FEMA, you should have at least a three-day supply of water and you should store at least one gallon of water per person per day. A normally active person needs at least one-half gallon of water daily just for drinking.
There are many different ways to store water, you can get cases of water, that are easy to rotate (just drink them, lol). There are water storage containers that require less rotation, but take up more room and when time does come to rotate, can call for some imagination. And of course, there are barrels to store water in.
Because Water takes up so much space, if you are starting out, go small and work up. Buy an extra case of water at the store next time, or if they are on sale, buy three. Whatever you choose, water is a must.  Here is a link that is helpful with storage and amount ideas.
