Something that should be high on your priority list when creating a food storage and products storage stockpile is a water stockpile. Every person needs water to survive so it should be one of the first things that you stockpile.
It is recommended that you store enough water for each person in your family for 2 weeks. Each persona should have 1 gallon of water each day in the stockpile so if you have 2 people in your family, you should have 28 gallons of water. If this is too much for you (if space is an issue) you should at least have 3 days of water stored for each person at the bare minimum.
What stockpile water? In case something contaminates your water source, in case you may be out of electricity and your well can’t function, in case bad weather comes and freezes your pipes. There are many different reasons to stockpile water, each one of them as important as the last.
If it works well for you, I’ve seen large food grade 55 gallon drums that you can store water in. If you are short on space but still want a decent water stockpile, this may be a good option for you. You shouldn’t use milk jugs to store water long term because they aren’t meant to hold liquid long term and the plastic will eventually break down. A good way to store water is in old pop liter containers or gallon size vinegar type plastic jugs. The plastic is thicker on both (and if you order them new you can get BPA free I believe) so they will last longer without breaking down. You can also get nice water storage containers online that hold more than 1 gallon and some are even stackable!
Store the water in a cool, dark area (like a pantry or a basement) to avoid wearing down the containers prematurely.
