Water is the single most important item in any emergency plan. A person can go three weeks without food but only three days without water, and the average American uses 80 to 100 gallons a day without thinking about it. When the tap stops, the question is not whether you need stored water but how much and in what container.
Our top pick is the WaterPrepared 55-Gallon Stackable Tank because it stores the most water in the smallest footprint, stacks to free up floor space, and includes built-in spigots so you can dispense without a pump. For modular storage you can spread across a home, the WaterBrick system is unbeatable.
Before you buy, run the numbers with our Water Storage Calculator so you know exactly how many gallons your household needs.

1. WaterPrepared 55-Gallon Stackable Tank: Best Overall
WaterPrepared 55-Gallon Stackable Tank
A rectangular, wall-hugging tank that stores 55 gallons in a tiny footprint, stacks two high, and dispenses through built-in spigots with no pump required.
The WaterPrepared tank solves the two biggest problems with bulk water storage: footprint and dispensing. Its flat, rectangular shape sits flush against a wall and stacks two units high, so a single column holds 110 gallons in roughly the floor space of a kitchen trash can. Round 55-gallon barrels simply cannot match that density.
Two built-in spigots, an upper and a lower, let you draw water by gravity without a siphon or bung wrench. The food-grade, BPA-free polyethylene is rated for long-term potable storage, and the wide fill cap makes cleaning and refilling straightforward. For most households this is the best single foundation for a two-week or longer water reserve.
Who it's for: Homeowners and apartment dwellers who want maximum stored gallons in minimum space, with easy dispensing built in.
What We Like
- Stackable design saves floor space
- Two built-in spigots, no pump needed
- Food-grade BPA-free construction
- Sits flush against walls
- Add tanks as your needs grow
Limitations
- Heavy and immobile once filled (about 460 lbs)
- Higher cost per unit than a plain barrel
- Needs a level, load-rated floor
2. WaterBrick Storage Containers: Best Modular System
WaterBrick Storage Containers
Brick-shaped 3.5-gallon containers that interlock and stack like building blocks, letting you tuck water into closets, under beds, and onto shelves throughout your home.
WaterBricks turn water storage into a modular system. Each container holds 3.5 gallons (about 28 lbs filled, light enough for most adults to carry), and their interlocking cross-stack design lets you build stable stacks up to four feet tall. Because each unit is small, you can distribute your supply across the house rather than dedicating a single large area to it.
The food-grade, BPA-free containers double as portable water if you have to evacuate, something a 55-gallon tank can never do. The molded-in handle and ventilated spout (spigot sold separately) make pouring easy. For renters, small spaces, and anyone who values flexibility, WaterBricks are the gold standard.
Who it's for: Apartment dwellers, renters, and preppers who want distributed, carryable storage rather than one heavy tank.
What We Like
- Interlocking, stable stacks
- Each unit is portable when full
- Distribute storage anywhere
- Food-grade BPA-free plastic
- Doubles as evacuation water
Limitations
- Higher cost per gallon
- Spigot often sold separately
- Many small caps to manage
3. Saratoga Farms 5-Gallon Stackable Set: Best 5-Gallon Set
Saratoga Farms 5-Gallon Containers
A four-pack of flat-bottomed 5-gallon jugs that nest and stack, with twist breathing ports for air-lock-free pouring. About 40 days of drinking water in one kit.
Five-gallon containers hit the sweet spot between capacity and portability. One filled unit weighs about 40 lbs, manageable for most adults to lift and carry short distances, and 20 gallons across four containers covers roughly 40 days of half-gallon-per-day drinking water for one person. The flat tops and bottoms nest together so you stack more water in less space than round jugs allow.
The built-in twist breathing ports are a small but meaningful touch: they vent air as you pour so the container does not glug and air-lock. For households that want to rotate water frequently and keep some of it grab-and-go portable, this set is a practical, mid-priced choice.
Who it's for: Families who want stackable storage in carryable units and the flexibility to grab a container and go.
What We Like
- Stackable flat-top design
- Carryable when full
- Twist breather ports stop air-lock
- Easy to rotate and refill
- Good capacity-to-portability balance
Limitations
- Less dense than a single tank
- 40 lbs is heavy for some users
- More caps and seals to check
4. WaterStorageCube Collapsible Container: Best Budget Pick
WaterStorageCube Collapsible Container
A food-grade collapsible jug with a spigot that folds nearly flat for storage and expands to hold up to 5.3 gallons when you need it. The cheapest way to add emergency capacity.
If you want emergency water capacity without dedicating permanent space to it, a collapsible container is the answer. Empty, the WaterStorageCube folds nearly flat and tucks into a drawer or bug-out bag. When a storm or boil-water notice is forecast, you unfold it, fill it from the tap, and use the built-in spigot to dispense. At around $22 it is the most affordable way to add capacity.
The food-grade, BPA-free material handles freezing better than rigid plastic because it flexes as ice expands. The tradeoff is durability: collapsible containers are best for short-term and on-demand use rather than years of continuous storage. Keep one or two on hand to top up your supply ahead of a known event.
Who it's for: Budget-minded preppers, renters with no spare space, and anyone who wants on-demand capacity ahead of a forecast event.
What We Like
- Around $22
- Folds flat when empty
- Built-in spigot dispenses easily
- Flexes instead of cracking when frozen
- Packs into a kit or car
Limitations
- Less durable than rigid tanks
- Best for short-term use
- Can develop seams leaks over time
5. Scepter 5-Gallon Water Can: Best Rugged Jug
Scepter 5-Gallon Water Can
A military-style rigid water can built for camping, off-road, and emergency use, with a leak-resistant easy-pour spout and rugged walls that shrug off rough handling.
Scepter built its reputation on military fuel and water cans, and that durability carries over to this 5-gallon model. The thick, impact-resistant walls and reinforced corners survive being tossed in a truck bed, dragged across a campsite, or stacked in a garage. The molded handle and easy-pour spout make controlled dispensing simple, even one-handed.
This is the container you want for vehicle kits, overlanding, and anywhere your water might take physical abuse. It is heavier and pricier per gallon than basic jugs, but it is built to last and rated for potable water. Keep one in each vehicle and your home reserve gains a mobile component.
Who it's for: Vehicle and overland kits, campers, and anyone who needs a tough container that survives rough handling.
What We Like
- Extremely durable construction
- Easy-pour spout for clean dispensing
- Great for vehicle and camp kits
- Rugged molded handle
- Trusted Scepter build quality
Limitations
- Pricey per gallon
- Heavier empty than thin jugs
- Single 5-gallon capacity
6. HOANK 55-Gallon Barrel: Best Value Barrel
HOANK 55-Gallon Water Storage Barrel
A traditional food-grade 55-gallon drum that delivers the lowest cost per stored gallon for households with the floor space to dedicate to bulk water.
When cost per gallon is your priority and you have the space, a classic 55-gallon barrel is hard to beat. The HOANK drum is made from food-grade, BPA-free plastic rated for long-term potable storage, and at around $115 it stores 55 gallons for less than many smaller kits. One filled barrel covers a family of four for nearly two weeks of drinking and cooking water.
The tradeoff is convenience. A round barrel does not stack efficiently, weighs over 450 lbs filled and cannot be moved, and you will need a siphon pump and bung wrench (often sold separately) to dispense. For a stationary basement or garage reserve where you simply want the most water for the least money, it is the value champion.
Who it's for: Homeowners with dedicated storage space who want maximum bulk water at the lowest price and do not need the tank to be portable.
What We Like
- Lowest cost per gallon
- Food-grade BPA-free plastic
- Large single-unit capacity
- Proven long-term storage format
- Simple, durable design
Limitations
- Round shape wastes space
- Needs a siphon pump and bung wrench
- Immovable once filled
How We Chose
We did not lab-test these containers ourselves. Instead, we researched and compared 25+ water storage products using manufacturer specifications (capacity, materials, dimensions, BPA-free and food-grade certifications), third-party safety listings, and patterns across hundreds of verified owner reviews. We weighed storage density, dispensing method, portability, durability, and cost per gallon to match each container to a real use case. Prices and availability change often, so confirm current details on the product page before buying.
Researched, Not Professional Advice
This guide is researched and educational, not professional emergency, medical, or safety advice. Recommendations are based on published specs and verified owner reviews, not in-person testing. Always follow manufacturer instructions, local water-safety guidance, and official FEMA, CDC, and Red Cross recommendations. Use stored water at your own risk.
Buyer's Guide: Choosing Emergency Water Storage
Step 1: Calculate How Much You Need
FEMA recommends a minimum of 1 gallon per person per day, with a 2-week supply for sheltering in place. A family of four needs roughly 56 gallons for two weeks before accounting for pets, hot climates, or medical needs. Start with our Water Storage Calculator to get your exact number.
Step 2: Match the Container to Your Space
- Have a basement or garage: A stackable WaterPrepared tank or a 55-gallon barrel gives you the most gallons per dollar and per square foot.
- Apartment or small home: WaterBricks or 5-gallon containers let you distribute storage across closets and under beds.
- Renters or no spare space: Collapsible containers store flat and fill on demand before a forecast event.
- Vehicle or evacuation: Rugged 5-gallon cans travel with you and survive rough handling.
Step 3: Prioritize Food-Grade and BPA-Free
Only store drinking water in containers specifically rated food-grade for potable water. Never reuse containers that held milk, juice, or chemicals; residual sugars and contaminants breed bacteria. All six picks above are BPA-free and food-grade.
Step 4: Plan Your Dispensing
A barrel is cheap but useless in a power outage if you cannot get water out of it. Tanks with built-in spigots, containers with pour spouts, or a dedicated siphon pump turn stored water into usable water. Decide how you will dispense before the emergency, not during it.
Rotate and Label Your Water
Label every container with the date you filled it and rotate stored tap water every 6 to 12 months for best taste. Keep containers out of direct sunlight, off bare concrete, and away from gasoline, pesticides, and other chemicals, which can permeate plastic.
Frequently Asked Questions
How much water should I store for emergencies?
FEMA recommends at least 1 gallon per person per day, with a 3-day minimum for evacuation and a 2-week supply for sheltering in place. A family of four needs about 56 gallons for two weeks. Hot climates, pregnancy, pets, and medical needs increase the amount. Use our Water Storage Calculator to size your supply.
What is the best container for long-term water storage?
For bulk long-term storage, BPA-free food-grade stackable tanks like the WaterPrepared 55-gallon tank offer the best density and easy dispensing. For modular storage spread across a home, WaterBricks are unmatched. For portability and rotation, 5-gallon stackable containers or rugged jugs are easiest to carry.
How long can you store water before it goes bad?
Water itself does not expire. In a clean, food-grade, BPA-free container kept out of sunlight and away from chemicals, stored water stays safe for a long time, but the Red Cross recommends rotating stored tap water every 6 to 12 months for best taste. Commercially bottled water has a printed shelf life of 1 to 2 years.
Do I need to treat tap water before storing it?
Municipal tap water is already chlorinated and usually does not need extra treatment in a clean container. For added protection or well water, you can add about 8 drops of unscented 6 percent household bleach per gallon before sealing. Always start with a clean, sanitized, food-grade container stored in a cool, dark place.
Are stackable tanks worth it over barrels?
Stackable rectangular tanks fit flush against walls and stack vertically, storing more gallons per square foot than round barrels, and they include built-in spigots for dispensing. Barrels are cheaper per gallon but round, harder to dispense from, and require a bung wrench and siphon pump.
Will stored water freeze and crack the container?
Water expands about 9 percent when it freezes, which can crack rigid containers filled to the brim. If storage may freeze, leave headspace and fill to about 90 percent. Collapsible and flexible containers handle freezing better than rigid tanks. Store off bare concrete on a pallet or shelf.
