Maybe it started with a headline about war, a storm warning, or a bare shelf at the store. Whatever set it off, you want a plan you can follow, not a list that makes you panic.
Here is the answer in one line: start with water. Ready.gov, the federal preparedness site, advises storing at least one gallon of water per person per day for several days and knowing how to make more water safe.
This guide takes you through that plan step by step, from how much water to keep, to food, outages, people and pets, and the product guides you may come across.

| Minimum water | At least 1 gallon per person per day, for several days, for drinking and sanitation (Ready.gov water page) |
| Normally active adult | About three quarters of a gallon of fluid daily, from water and other beverages |
| Very hot weather | Water needs can double |
| Boiling | Bring water to a rolling boil for one full minute, then let it cool |
| Household bleach | Regular unscented bleach at 5.25 to 6.0 percent sodium hypochlorite: 1/8 teaspoon per gallon, stand 30 minutes |
| Self-filled containers | Replace every six months. Commercially bottled water stays in its sealed original container |
| Not recommended by Ready.gov | Iodine, and camping or surplus-store treatment products that do not use 5.25 or 6.0 percent sodium hypochlorite as the only active ingredient |
Where are you starting?
Step 1: Figure out how much water you need
You are starting with the biggest question: how much water to keep on hand. Ready.gov says to store at least one gallon of water per person per day for several days, for drinking and sanitation.
A normally active person needs about three quarters of a gallon of fluid daily from water and other drinks. Children, nursing mothers and sick people may need more, and a medical emergency can add to that need. Ready.gov also says never ration drinking water unless authorities order it.
On the question of a war: the water guidance on Ready.gov is written for emergencies in general, not for one war. The same steps apply whatever caused the disruption: store water, know how to make more safe, and keep it rotated.
What this means for you: Count the people in your home, multiply by the number of days you want covered, then add extra for children, sick people and hot weather. Write that number down before you buy anything.

30-Day Water Storage Plan for a Household: how to scale your daily number into a month.
For the wider picture, see the food and water storage guide, and use the household water worksheet to write your numbers down.
Once you know the number, the next question is whether your tap can be trusted, and how to make water safe if it cannot.
Step 2: Learn how to make water safe
Your stored water runs out, or your tap water looks or smells wrong. This is the step that keeps you from getting sick.
Ready.gov says to treat all water of uncertain quality before you drink it, cook with it, wash dishes, brush your teeth or make ice. It warns that contaminated water can carry germs that cause dysentery, cholera, typhoid and hepatitis.
Boiling is the safest method according to Ready.gov. Bring water to a rolling boil for one full minute, allowing for some evaporation, then let it cool. If the water is cloudy, let particles settle or strain it through coffee filters or clean cloth first.
| Method | Kills microbes | Removes other contaminants (heavy metals, salts, most chemicals) |
|---|---|---|
| Boiling | Yes | No |
| Chlorination (bleach) | Yes | No |
| Distillation | Yes | Yes |
If you cannot boil, Ready.gov describes chlorination with household liquid bleach. Add 1/8 teaspoon per gallon, stir and let it stand 30 minutes. The water should smell slightly of bleach; if it does not, repeat the dose and wait 15 more minutes. If it still does not smell of chlorine, discard it and find another source.
Distillation removes more. Fill a pot halfway, tie a cup to the lid handle so it hangs upright without touching the water, and boil for 20 minutes. The water that drips into the cup is distilled.
Your tap water is a separate question. MedlinePlus, from the U.S. National Library of Medicine, says the water supplier must give you annual reports that list where your water came from and what contaminants are in it. A 2016 review in Current Environmental Health Reports notes that young children, pregnant women and fetuses may be especially susceptible to perchlorate in water.
What this means for you: Boil first. Use bleach only when you cannot boil, and use the exact bleach strength Ready.gov lists. Skip iodine and camping-store treatments that do not use 5.25% or 6.0% sodium hypochlorite as the only active ingredient.

Compare the methods in the water purification comparison, and keep the boil water advisory checklist for when your utility issues a notice.
With safe water in hand, the next job is keeping it safe while it sits on your shelf.
Step 3: Store water so it stays safe
Water you store is only useful if it is still safe when you need it. Ready.gov gives clear rules for how to keep it that way.
- Buy commercially bottled water and keep it in the sealed original container, in a cool, dark place.
- If you fill your own containers, use food-grade containers only.
- Clean them with dishwashing soap, then sanitize with one teaspoon of unscented liquid household chlorine bleach per quart of water.
- Replace water that was not commercially bottled every six months.
- Label every container you fill with the date, so you can see what to rotate first.
What this means for you: Set a calendar reminder for every six months. Rotate the water you filled yourself, and keep the sealed bottled water on the shelf until you need it.

For the storage details, read how to store water for emergencies. If you live in an apartment, the urban apartment storage guide covers small spaces.
Food is the last big piece, and it is easier once water is handled.
Step 4: Build a food supply you will actually rotate
Most people asking about food want a list. Start with a list that matches what your household eats, then keep it moving.
Ready.gov, on its water page, links to a recommended emergency supplies list in PDF form. Use that as your printable base, then swap in foods your family will eat. Ready.gov is the federal site, so it is a sound starting point.
You will see many “top 10”, “C’s of survival” and “20 items” lists. Treat them as checklists, not rules. The 3-3-3 rule is a memory aid for setting priorities, not a timer to test.
What this means for you: Buy one extra of what you already eat each shop, put new items behind old ones, and use the oldest first. That habit beats any shopping list.

Food and water both need to be ready for the power to go out, so the next step covers the outage itself.
Step 5: Plan for the toilet, the fridge and the outage
When the power goes out, the questions shift to flushing, sanitation and the food in your fridge.
The flush guide walks through the checks to run first.
Ready.gov says to treat water of uncertain quality before you use it for washing dishes, brushing teeth or making ice. Plan hand washing and toilet routines that do not depend on running water, so you are not improvising.
What this means for you: Test your toilet and tap before you need them. Write down what to do if water stops, and keep that note with your supplies.

Can You Flush During a Power Outage?: the checks to run first.
For the fridge, the power outage food safety guide explains when refrigerated food must be discarded. For a full household routine, read the emergency sanitation during a water outage guide.
Outages hit people differently, so the next step covers the household members who need more.
Step 6: Plan for people and pets with extra needs
Your household may include small children, a nursing parent, a sick family member, or pets. Each one changes the plan.
Ready.gov says children, nursing mothers and sick people may need more water, and a medical emergency may require additional water. If someone in your home has a health condition that affects fluid needs, ask their clinician how much water they should keep on hand.
Pets need water on your list too. Give them their own line in the plan, not whatever is left after people are covered.
What this means for you: Write a separate line for each person and pet with extra needs, and keep the medicines and contacts list with that line.

Once the household plan is set, you can look at products. Do that with a checklist, not a hurry.
Step 7: Read product guides with a buyer checklist
You may have seen an ad for a water generator, a filter or a survival kit. Our product guides lay out what each seller says the product does, its price and its refund terms. The seller’s claims stay the seller’s claims, and the guide shows you what to check.
- Confirm the exact product name and version.
- Read what the seller says it does, in the seller’s own words.
- Add up the total price, including shipping and any recurring charges.
- Find the refund terms and who pays return shipping.
- Check whether the product replaces your stored water or treatment, or only adds to it.
- Look at any study the seller cites, and check whether it tested this product or a different one.
Nothing in a product sale replaces the basics in Steps 1 to 3. A product is an extra, not the plan.
What this means for you: If a product’s pitch skips the price, the refund terms or the exact model, pause. Ask the seller for those details in writing before you pay.

Last, keep the plan working over time.
Step 8: Keep your plan current
A water plan goes stale unless you keep it current. Most of the work is small and repeats on a schedule.
Ready.gov says self-filled water should be replaced every six months. Keep copies of your key papers in a safe place. Keep receipts for what you buy and what you lose, since those records help after an emergency.
What this means for you: Put a date in your calendar every six months for water rotation. Check your evacuation route at the same time.
