The Ultimate Prepper’s Guide to Water Use & Storage

Out of all the elements to consider when preparing for a disaster, few are as logistically challenging as water use and storage.

Let’s break down this common preppers question so you’re prepared if an emergency situation ever shows up in the United States.

How Much Water Should I Use Per Day?

Long term water storage is heavily dependent on how much water you have to consume every day. Only then can you figure out how to cut back on water consumption.


The official medical recommendation is that men drink about 15.5 cups or 3.7 L of water per day, while women need to consume 11.5 cups or 2.7 L per day. That’s just for drinking and healthy hydration.


However, you’ll naturally get a little bit of your daily required water from your food, so you can safely drop this down a bit.

You also have to account for other uses of water, like:

  • Radiator Cooling
  • Washing
  • Cooking
  • Sanitation

Furthermore, your water consumption may need to go up during the hotter months of the year or if you live in a particularly humid environment. The same is true if you spend a lot of time outside doing physical activity.

Don’t discount the fact that pregnant women and sick require more water storage as well.

So how much water should you consume per day?

If you’re looking to adequately prepare, assume that you’ll need something closer to 5 L of water per day per person, especially to give yourself a little bit of wiggle room. That’s a little bit over 1 gallon of water per person per day.

Now you can see how much water containers you’ll need and how quickly it all piles up.

How Much Water Should I Store?

This is dependent on exactly how bad the current crisis is and how long you need to hold out.


A good rule of thumb is that, if rescue doesn’t come within two weeks, it probably isn’t coming at all.


That’s why it may be a good idea to have about two weeks’ worth of water stored at your home or at a safe hideout. This gives you enough water supply to survive for a good chunk of time while you gather information and wait out the immediate danger of whatever crisis you’re facing.

However, even one week’s worth of water is better than none. Go higher if you can, of course, but don't overdo it.

Remember that all storage containers you store takes up space, time, and energy.

What is the Best Way to Store Water?

There’s lots of literature about how to store your water supply in a crisis, created thanks to the real experiences of people who lived through terrible events.


Here are some good general water storage tips:


  • Only order water containers with a top that can be closed securely
  • Obtain water storage containers made of durable and non-breakable materials, like plastic, instead of glass
  • Avoid plastic water bottles
  • Use a container with a narrow neck – this allows you to pour the water accurately
  • Only use clean containers that have not been contaminated with pesticides or bleach
  • If necessary, go through a water purification process by boiling it
  • If possible, set up a water filtration system

It’s a good idea to have a central water storage location in your home where you and your family can retrieve water when necessary.

DO NOT give this location out freely since, depending on the circumstances, your water sources might turn into a target for looters.

Surviving a crisis will be tough, no doubt about it. But following these tips will go a long way toward ensuring your safety.
