Water has been on my preparedness list for a long time.
I have emergency water containers. I’ve made room for them in the garage. I’ve thought about how much water my family would need if something happened to our normal supply.
In my head, water storage was something I had at least partially addressed.
Then I started working on this article and realized something I’m not particularly proud of.
Every one of my emergency water containers is empty.
I own the containers.
I have the storage space.
But if the water stopped flowing tonight, none of that would give my family a single gallon of stored water.
That realization sent me down another preparedness rabbit hole, starting with a deceptively simple question:
How much water should I actually be storing?
And once I started doing the math, the answer got big very quickly.
The Official Recommendation Is a Starting Point
According to the CDC's emergency water-supply guidance, households should store at least one gallon of water per person per day for three days, and should try to store a two-week supply if possible.
That water isn't just for drinking. Water may also be needed for cooking, brushing teeth, and other basic uses.
The CDC also recommends considering additional water for circumstances including pets, illness, pregnancy, and hot climates.
Here in Washington, the Washington State Department of Health recommends one gallon per person per day for at least two weeks.
For my household, even that adds up quickly.
There are five people in our family.
At one gallon per person per day:
3 days = 15 gallons
1 week = 35 gallons
2 weeks = 70 gallons
30 days = 150 gallons
And that's before accounting for our three dogs.
But I've decided I don't want to build our water plan around the minimum.
I'm Planning Around Two Gallons Per Person
My personal goal is closer to two gallons per person per day.
That's not an official recommendation. It's the planning number I've chosen for our family because I want some margin for more than simply having enough water to drink.
Drinking obviously comes first, but we'd also potentially need stored water for cooking, brushing our teeth, limited dishwashing, and basic hygiene.
I would rather plan high and conserve during an emergency than plan for the absolute minimum and discover that we need more.
But two gallons per person per day changes the math considerably.
For five people:
1 day = 10 gallons
1 week = 70 gallons
2 weeks = 140 gallons
30 days = 300 gallons
Then there are the dogs.
Suddenly my idea of eventually having a month's worth of water isn't a few containers sitting in the corner of the garage.
It's hundreds of gallons of water.
And water is heavy.
A gallon of water weighs a little over eight pounds. Three hundred gallons would weigh roughly 2,500 pounds.
That was the point where this stopped being a question of simply buying enough containers.
It became a question of building a realistic system.

What I Already Have
My current containers are 7-gallon Reliance Aqua-Tainers.
According to the manufacturer, the Aqua-Tainer is a food-safe water container with an integrated handle and reversible spigot, which makes it useful for both storing and dispensing water. Reliance Outdoors — Aqua-Tainer
I currently own nine of them.
Nine containers at seven gallons each gives me:
63 gallons of water-storage capacity.
Except, as I mentioned earlier, they're currently empty.
That's an important distinction.
Owning water containers isn't the same thing as storing water.
I think this is an easy trap to fall into with preparedness gear.
You buy something because you've identified a vulnerability. It goes into the garage, closet, emergency kit, or storage room. Mentally, that problem starts feeling checked off.
But equipment that hasn't actually been incorporated into your emergency plan may not solve the problem you bought it to solve.
My nine Aqua-Tainers are a perfect example.
I had planned to clean, sanitize, and fill them while working on this article. I even planned to take pictures of the process.
Then I couldn't find the drinking-water hose I wanted to use for filling them.
Then the weekend got busy.
And here we are.
They're still empty.
I could have waited to publish this article until everything looked finished, but I think that would miss one of the more important lessons I've learned through this project.
Knowing what you should do and actually getting it done are two very different things.
My First Goal: 84 Gallons
Where I currently store the Aqua-Tainers, I have room for twelve.
So my immediate plan is pretty simple:
Buy three more.
Clean and sanitize all of the containers.
Fill them from a safe drinking-water supply.
Label them with the date.
And actually turn that storage capacity into stored water.
Twelve 7-gallon containers would give us 84 gallons.
At the official one-gallon-per-person-per-day baseline, that's more than two weeks for our five-person household before accounting for the dogs.
At my more conservative two-gallon planning target, however, it's only about 8.4 days for the five of us, again before accounting for the dogs.
That surprised me.
Twelve fairly large water containers take up a meaningful amount of space, yet they still wouldn't give us anywhere near the month of water I'd eventually like to have.

Stored Water Has to Be Maintained Too
Another thing I needed to learn was that filling the containers isn't the end of the job.
The CDC recommends washing reusable water-storage containers with soap and water and rinsing them completely before sanitizing them.
For sanitizing, the CDC recommends a solution of 1 teaspoon of unscented household chlorine bleach containing 5–9% sodium hypochlorite mixed with 1 quart of water.
The container should be closed and shaken so the solution contacts all of the interior surfaces. The CDC says to wait at least 30 seconds before pouring out the solution and allowing the empty container to air-dry before use.
Once filled, the CDC recommends labeling the container as drinking water, including the storage date, and replacing self-filled stored water every six months.
The Washington State Department of Health also recommends replacing self-filled water every six months and keeping containers tightly sealed in a cool, dark location.
That means water storage isn't something I can simply fill once and forget about.
It needs to become part of our normal preparedness maintenance.
But 84 Gallons Still Isn't a Month
This is where my longer-term plan starts changing.
I'd eventually like to add a couple of much larger food-grade water-storage tanks. Two 55-gallon tanks would add another 110 gallons.
Combined with twelve Aqua-Tainers, that would put us at roughly:
194 gallons of stored water.
That's a lot of water.
It's also still less than the 300 gallons represented by my two-gallon-per-person, 30-day planning target—and that's before I've properly accounted for the dogs.
I don't think the answer is necessarily to keep buying containers until every possible gallon we might need for a month is sitting in the garage.
Instead, I'm starting to think about water preparedness in layers.
Layer 1: Portable Stored Water
The Aqua-Tainers give us water that is relatively easy to access, dispense, and move.
A full seven-gallon container is heavy—nearly 60 pounds of water alone—but it's still movable.
That portability could become important later.
Layer 2: Bulk Water Storage
Larger tanks would significantly increase the amount of water we could keep at home without requiring dozens of individual containers.
They wouldn't be particularly portable, but they wouldn't need to be.
Their job would be extending the amount of time we could remain independent of the normal water system.
Layer 3: Finding More Water
Eventually, though, almost any practical stored supply can run out.
At that point, the problem changes.
It isn't:
How much water do we have stored?
It becomes:
Where can we get more?
We have a potential natural water source within reasonable walking distance of our home. We also own a folding wagon that could carry a couple of the 7-gallon Aqua-Tainers.
That means those containers could eventually serve a second purpose. They aren't just storage—they could become a way to transport additional water home.
But there's an enormous caveat.
Finding water and finding safe drinking water are not the same thing.
Water collected from a river, lake, stream, or other untreated source shouldn't simply be assumed safe because it looks clean.
And, as the CDC notes in its emergency water guidance, water contaminated with fuel, toxic chemicals, or radioactive materials cannot be made safe simply by boiling or disinfecting it.
That's important enough that I'm not going to squeeze it into the end of this article.
It's what I'm researching next.
The Hole I Found in My Own Preparedness
When I started thinking about this article, I expected it to be about how much emergency water a family should store.
Instead, it exposed a hole in my own preparedness.
I have backup power.
I have ways to cook when the power is out.
I've spent time thinking about food, communications, emergency information, and plenty of other things that could become important when normal systems aren't available.
I even bought dedicated emergency water containers.
But right now they're empty.
If our water stopped flowing tonight, having nine blue containers sitting in my garage wouldn't help very much.
That's uncomfortable to admit.
But it's also exactly why I'm doing The Ready Dad Project.
I'm not trying to build the perfect emergency setup and then tell everyone else how to do it.
I'm trying to look honestly at where my family is prepared, where we're not, and what we can realistically improve.
Water just moved much higher on that list.
My next step isn't another complicated preparedness project.
It isn't another piece of technology.
And it isn't buying a bunch of new gear.
It's filling the containers I already own.
Sixty-three gallons won't get my family through a month.
But 63 gallons of actual water is infinitely more useful than 63 gallons of empty storage capacity.
And that's where I'm starting.
The Ready Dad Challenge
Take five minutes and figure out how much emergency water you actually have in your home right now.
Not how many empty containers you own.
Not how much water you could theoretically collect.
Not what you plan to buy someday.
How many gallons of usable water do you have available if the faucets stopped working tonight?
Then compare that number with the number of people—and animals—depending on you.
You might be surprised by the answer.
I certainly was.
Next: Stored water eventually runs out. In Article 8, I'm going to look at the other half of the problem: finding additional water and making it safe enough for my family to use.
Practical resilience for everyday families.
