water storage needs of woman and child

Key Factors:

  • The CDC recommends storing 1 gallon of water per individual per day for emergencies.
  • I like to recommend preppers retailer 1.5 gallons per individual per day.
  • Our water calculator may help you crunch the numbers on how a lot you want.
  • Water is cumbersome and heavy, requiring cautious storage planning.

How a lot water do it’s essential to retailer? Water storage is just not the sexiest factor to speak about on the subject of prepping, nevertheless it’s in all probability crucial. Precisely how a lot water do you have to retailer? I made a calculator to assist reply that, however mainly…

I like to recommend storing 1.5 gallons of water per individual per day as a normal guideline. Nevertheless, that’s an exceptionally subjective quantity. It’s about like calculating how a lot ammo you want – extra! The reply is at all times extra.

“Extra” is just not a useful reply, nevertheless. In the event you’re like me, you need to plan your preps, not simply go at it willy nilly. You save money and time by going about prepping strategically, by constructing a SHTF plan after which growing a plan to fulfill your wants ought to circumstances take a flip for the more serious. “Extra” simply means there’s by no means an finish, and I prefer to really feel like I’m making progress in my preps.

Water storage isn’t precisely as straightforward as simply filling bottles, nevertheless…

Water takes up house!

See a number of of the completely different water containers I’ve under. The SureWater tank on the left holds 260 gallons. The tenting water jug within the center holds 5 gallons. The Wurx container on the suitable holds 20 gallons.

Totally different sized water containers.

I’m lucky to have the house to retailer water, however the house required makes “extra” a very ineffective reply, as a result of for most individuals, cupboard space shortly turns into a problem you probably have lofty objectives, i.e. you need to retailer months’ price of water. In the event you reside in a small home, or an residence, it will likely be a problem to retailer sufficient water for your self – much more so you probably have a household.

Image your normal five-gallon fish tank. It’s not enormous, nevertheless it takes up sufficient house that it normally calls for its personal designated house on a small desk. Now think about you need to retailer 50 gallons of water to begin. You want ten of these tanks. Out of the blue you’re trying round your house questioning… the place!? How do you do that with out turning your home into an aquarium?

Water can also be heavy!

One gallon of water weighs 8.345 kilos. That very same 50 gallons described above, not solely are you now in search of house, however you’re in search of house that may simply maintain 417.25 kilos (50 x 8.345). You’ll be able to retailer bulk meals on a closet shelf. That’s not going to occur with water. And for those who get even heavier with extra gallons, you’ll quickly be trying completely at ground house in basement or on a concrete slab.

I don’t blame you for those who’re now considering this isn’t price it, I’ll return to constructing my bug out backpack. That’s actually extra enjoyable, however earlier than you try this, let me clarify why overlooking water storage is such a foul thought.

Right here’s the calculator. Plug in your assumptions, examine your outcomes, after which lets dig additional into this topic of how a lot water it is best to retailer.

5 Causes Each Prepper Ought to Begin Storing Water

I make the case why each prepper ought to begin their provides with water in my prepper provides article. The final gist lies within the following ideas.

#1 – Lack of Clear Water is Widespread in Catastrophe Conditions

Put up-disaster, clear water goes to vanish – and this might occur in a single day. We presently reside in a society the place water is ever current, and for a lot of, we’ve come to take entry to scrub water with no consideration.

Nevertheless, after many pure disasters, clear water is usually the very first thing to go. I emphasize “clear” as a result of there’s normally nonetheless water accessible – someplace. The truth is, within the case of a flood, the issue is an excessive amount of water! However anybody that’s been round a flood or two is aware of the inflow of water usually contaminates ingesting water and ends in boil water advisories.

In accordance with the College of Nebraska-Lincoln Institute of Agriculture and Pure Sources:

Floodwaters can absolutely inundate water wells for days or perhaps weeks. The drive of floodwaters also can disrupt or injury effectively or water provide infrastructure and instantly introduce the contaminated water into the effectively.

Past floods, water usually turns into an issue when the facility goes out. When you have a effectively pump you want a generator to attract from it. In the event you’re on public water it ought to nonetheless circulation because the stations have mills. If the facility goes out for good (suppose EMP), you’re out of luck. You’re left with the pure water that is perhaps round you outdoors, or what you will have saved. If it’s a drought, issues are even worse.

#2 – Organic Want – Hydration

Maybe the obvious cause to begin your water storage is as a result of all of us want water to remain alive! People can solely go a 3 days with out water, and even making an attempt to get that far with out it will be depressing. In the event you’re outdoors doing strenuous work within the solar, going with out sufficient water will result in complications, irritability, and heat-related accidents.

#3 – Cooking

In the event you’re going to cook dinner post-disaster (and you’re), then it’s essential to have water put aside for laundry meals and boiling meals. Preppers are recognized for his or her storage of beans, bullets, and band-aids, however have you ever ever tried to eat dried beans with out water? You’ll be able to’t.

Whether or not we’re speaking concerning the sacks of rice, beans, flour, lentils, or no matter different dried items you’ve been storing, you’re going to want some approach to make these meals edible, and means water.

Even for those who suppose you’re simply going to reside off MREs within the aftermath of a catastrophe (they’re not as wholesome as you suppose), you continue to want water to activate the chemical heater. What’s extra, all of that freeze-dried survival meals to procure, that can want water to turn into rehydrated.

#4 – Cleansing

When the facility goes out, it’s not an enormous deal to go and not using a bathe for a day, however remembering the Maine ice storm of of 1998, when freezing rain fell for about 50 hours leading to about 200,000 studies of energy outages, it took as much as 20 days for some components of the state to get energy again. Folks had been stealing mills. Any restaurant with energy was flooded with individuals in search of a sizzling meal. Many ended up renting resort rooms simply to get a sizzling bathe.

On my backpacking journeys, I could make it a few most of 2-3 days earlier than I want to search out some approach to clear myself. Any longer than that and I’m feeling fairly gross. Granted these are exercise-filled, sweaty days, however correct hygiene is an should for post-disaster populations. Those that let that slip to the wayside are at an elevated threat of contracting varied illnesses.

Past our our bodies, in any kind of grid down/collapse scenario, we’ll finally want to scrub our garments. We’ll want to scrub our dishes. We’ll want to scrub surfaces. In different phrases – we’ll want clear water.

#5 – Water is an Simple (and Free) Place to Begin

With regards to prepping, there’s actually no cause not to begin with water. Earlier than catastrophe hits, you could find it nearly in all places, and the very best half is, it’s both extremely low cost or solely free! Simply flip in your faucet and begin storing. You’ll instantly have a way of prepping progress as you stack saved water.

How A lot Water Do You REALLY Have to Retailer?

water tower
It would really feel such as you want a water tower to retailer sufficient for the apocalypse, however dthere are some workarounds.

In the event you don’t like my recommendation of 1.5 gallons per individual per day, that’s fairly effective. It’s not a regular that’s going to work for everybody, not to mention one that everybody can agree on. If you wish to give you your individual metric to find out how a lot it is best to retailer, it’s important to determine how a lot water you actually want?

To reply that query, it’s essential to determine two issues:

  1. How a lot water you employ at present
  2. The place you’re keen to chop water consumption throughout a disaster

How A lot Water Do Individuals Use?

In accordance with the EPA, the common American household makes use of 300 gallons of water per day at house. Roughly 70% of that’s indoor use. In the event you determine the common household is a household of 4, that’s 75 gallons per individual per day.

How can that be!? you would possibly surprise. And right here I’m suggesting 1.5 gallons per day. Fairly a distinction!

Contemplate the common American house. We take lengthy showers (generally baths), we wash garments, we’ve got dishwashers, we’re continuously flushing the bathroom, we wash our vehicles, we water our lawns, the listing goes on and on.

water usage chart

The 300 gallons quantity additionally accounts for all use, even oblique use, averaged out by household depend. We’re not directly utilizing way more water than we expect. The meals we purchase on the grocery retailer, there was water used to provide that. The power used to energy our properties, water went into that too.

So, you’ll be able to see how a lot water is getting used – a ton (1.25 tons per household to be exact (8.33lbs per gallon x 300 gallons = 2,499 kilos)). You may also start to see how, in a catastrophe scenario, our water consumption will drop off dramatically.

How Do We Lower Water Use in a Disaster?

There may be nothing “regular” a few disaster. That’s what makes it a disaster, in any case. So, you’ll be able to throw that 300 gallons per household determine the window. Right here you’re going to have a look at precisely what you’re going to want water for, your direct and quick consumption wants in a disaster.

That is made simpler by crossing some “regular” water makes use of off the listing:

  • You’ll not be watering your garden, washing your automobile, or something like that.
  • Assuming you’ll be able to even run a garments washer, you’re not going to want to clean garments every day. Just a little grime in your denims received’t be the top of the world.
  • You’ll be able to wash dishes by hand and save lots of water over utilizing a dishwasher.
  • In accordance with a 2016 examine, we use roughly 17 gallons of water for an eight-minute bathe. We received’t want every day showers after a collapse. Ever hear of a sponge tub? They’re not only for infants.
  • Will you actually need to flush your bathroom that always? If it’s yellow let it mellow! Alternatively, dig a latrine to your poop and pee outdoors!

Give attention to Your Water Wants

For planning functions, fairly than ranging from the place you’ll be able to minimize water, you can too begin from the place you should have water. That is going to come back down to a few core classes: hydration, cooking, and cleansing.


How a lot water do it’s essential to keep hydrated? That relies upon. How a lot do you weigh? What’s local weather are you residing in? Are you partaking in bodily labor? As a tough information, take into account this recommendation:

Intercourse Beneficial Day by day Water Consumption
Feminine 11.5 cups (0.72 gallons or 2.7 liters)
Male 15.5 cups (0.97 gallons or 3.7 liters)

Out of the blue 1.5 gallons doesn’t look like lots, does it? Add in some cooking and a few cleansing and also you’re at that 1.5 gallon per individual per day suggestion fairly simply. If it’s important to account for a sizzling/humid local weather and/or bodily labor, the quantity begins creeping up fairly shortly.

In fact, for those who’ve ever tried to drink a gallon of water a day you realize it’s not straightforward, however that’s straight water consumption below regular circumstances. In a standard day you might also be ingesting espresso, tea, soda, juice, and so on. Lower all of these out and drink nothing however water and a gallon a day isn’t as tough.


Cooking requires water use as effectively. The usual for pasta, for example, is 4-6 quarts of water per pound of pasta. That’s a minimal of 1 gallon of water to 1 pound of pasta.

We may minimize the “normal” water-to-pasta ratio in a disaster, however simply taking a look at freeze dried meals, the place the entire water finally ends up absorbed within the meals itself, you continue to want loads of water.

Take for example the 2 photos under. I took these off some freeze-dried merchandise I bought from Emergency Necessities. The primary is from a #10 can of white cheddar mac and cheese. The second is off single serving of their excessive protein vanilla shake combine.

freeze dried mac cheese directions
Freeze dried mac & cheese requires 1 cup of water for each 1/3 cup of pasta.
vanilla meal shake directions
A vanilla meal shake requires 1.5 cups of water.

Arthur T. Bradley, bestselling creator of the Handbook to Sensible Catastrophe Preparedness for the Household, places his cooking/ingesting quantity considerably decrease. In accordance with him, the common human can get by with only a gallon of water a day on the subject of each ingesting and cooking. He appears to be following the CDC tips, and that “one per one” does make for a simple calculation.

There’s nothing mistaken with beginning with 1 gallon per individual per day. One thing is healthier than nothing, and if nothing else, that determine will get you 66% of the way in which to my suggestion.


That is the place the water wants can add up. Investing in a five-gallon tenting bathe is a smart thought as a prepper. If we assume you’re solely going to take 2 showers/week (and use the total 5 gallons), that’s 10 gallons per week. You’ll be able to minimize that showering assumption, as I discussed, with a sponge tub, however… anybody with lengthy hair would possibly disagree.

Regardless, let’s additionally say that you just’re going to make use of a 3rd of a gallon/day for laundry your fingers, and one other 1/3 gallon per day to clean dishes. Add that in.

outhouse as a water saver
The bygone outhouse, it may show to be one in all your greatest water savers in a disaster.

What about bathrooms? In the event you’re in a scenario with out energy, you’ll need to pour water in the bathroom tank as effectively. You don’t need to waste clear water on this although. In the event you can catch your used grey water (from showers, dish washing, hand washing, and so on.) this water could be excellent for flushing.

Personally, I’ve a Luggable Bathroom for such a scenario. Past the Luggable Bathroom, you would additionally construct a latrine outdoor for those who’re residing someplace rural.

In a short-term winter storm-type scenario, certain, I’ll use water to flush a bathroom. However in a grid down, EMP kind SHTF scenario – there’s no method I’m utilizing clear water to flush a bathroom. Pond water, stream water – these are choices. You possibly can additionally try and seize any bathe water for flushing a bathroom. In different phrases, you would discover methods to get artistic and in some circumstances, use water twice.

If we assume that we’re going to hand-wash our garments as soon as per week utilizing a Scrubba, for example, that makes one other 7 gallons of water/week/individual.

We are able to lower total water wants by taking fewer showers, utilizing a compost bathroom, utilizing disposable plates and silverware, melting winter ice (now you’re stocking extra gasoline), and so forth. My total level right here is that…

I Stand By 1.5 Gallons Per Individual Per Day

Higher to overprepare than underprepare, and 1.5 gallons per individual per day – I believe – is just not overpreparing.

That stated, I acknowledge that your ends in the water calculator could appear intimidating. The truth is, it in all probability is, however relying on the place you reside, you might have strategies to reinforce this water storage with water assortment methods, drawing water from a pond, constructing a rain catchment system, and so on. Nonetheless, it’s good to have clear, potable water saved regardless.
