  • Made In The USA

Materials: High Quality LLDPE Plastic

Features: BPA-Free, UV Resistant tank

Stackable with Similar Units

If you want to store multiple 50-gallon tanks of water, the Smart Tanks are completely stackable. Not only that, but even when they’re stacked up, you can access the spigots and even the inlets for adding water. Molded side-handles also allow you to maneuver the barrels easily.

Made in the USA

Items made in the domestic US are often a big draw for buyers. Whether you want to ensure there are no harmful chemicals in your products or if you want to make sure you can get in-country support for any problems, buying US-made might be a priority.

UV-Resistant (and BPA-Free)

UV resistance means your water storage barrel won’t break down if it’s exposed to sunlight. While you want to store your water in as cool and dark a spot as possible, you can rest easy knowing nothing will be leaching into your water from the container.


  • Stackable units—with access to spigots even when stacked
  • Water inlet and outlet pre-drilled with spigots

High Water Storage Capacity

At 65 gallons, the RomoTech reservoir can handle a lot more water storage than alternative options. Plus, RomoTech offers sizes up to 550 gallons for home (or homestead) water storage. Compatibility with a standard garden hose plus other attachments makes these tanks easy to fill and empty.

Easy Water Level Visibility

With a see-through design, you can tell exactly how much water is in your tank. There are molded-in graduation marks in both liters and gallons, so you’ll never have to wonder how much water is left.

  • Meets NSF/ANSI Standard
  • Tank Ball Valve Included Connection To RO Systems

Materials: Food Grade Material

Works Horizontally and Vertically

Wherever you want to put the iSpringT32M storage tank, it can still deliver the pressure you need. It works both horizontally and vertically, so fitting it into your home (or even under the sink) won’t be an issue.

Arrives Pre-Pressurized

While you’ll want to check the pressure before using this four-gallon tank, it comes pre-pressurized. That means you shouldn’t need to mess with pressure adjustments—just fill and go with the tank.


  • Can work with nearly any installation configuration
  • Meets NSF/ANSI standards
  • Pre-pressured to 7-10 PSI
  • Comes in multiple sizes to suit your water storage needs
  • Flavorless water storage—metal interior with a food-grade coating


  • Need to test the pressure before using—it may be off by a few PSI
  • The internal pressure bladder can be damaged
  • The label says four gallons, but the instructions note 3.2 gallons (given the size of the bladder inside)
  • Relatively short life expectancy

4. RO Expansion Tank 4 Gallon – NSF Certified – Compact Reverse Osmosis Water Storage Pressure Tank by tankRO – with Free Tank Ball Valve

RO Expansion Tank 4 Gallon – NSF Certified – Compact Reverse Osmosis by tankRO – with Free Tank Ball Valve

  • 1/4" Tank Valve Is Included
  • Quick Connect Compatible
  • NSF Certified
  • Post Cured Diaphragm Keeps Your Water Safe

Compact Size

When you need to store water under the kitchen sink, a trim profile is a necessity. The RO Expansion Tank stores underneath your countertop or anywhere else easily. Its four-gallon size doesn’t take up much space.

Compatible Fittings for Valves

If you’re installing the tank under your sink, you probably want to connect it to your existing faucet. The compatible fittings allow you to hook the tank into your water delivery system. So, you can connect your water filtration equipment to the tank, then connect the sink to the tank. Then, you’ll have clean, filtered water on demand.

Works Side-Lying and Upright

While it fits just about anywhere, the RO tank can also lie on its side and still offer adequate pressure. That means even more installation options, no matter where you need to put it.


  • Installs on its side or vertically
  • Food-grade materials
  • Pre-pressurized
  • NSF Certified
  • Fits nearly anywhere


  • Only holds 3.2 gallons despite being a “four-gallon” model
  • Aims to last about five years—so a limited lifespan
  • Can be challenging to sanitize since it doesn’t open at the top
  • Supplied valves aren’t universal, so you might need additional equipment to install

5. Reliance Products Jumbo-Tainer 7 Gallon Jerry Can Style Rigid Water Container

Reliance Products Jumbo-Tainer 7 Gallon Jerry Can Style Rigid


  • Dual Handles Facilitate Simple Lifting And Pouring
  • Reliable Tap-Style Spigot
  • Durable And Affordable
  • NSF Certified

Materials: 100% Polyethylene

Features: BPA Free Plastic

Stores Horizontally or Vertically

With two handles and a rectangular shape, the can-style jug can rest vertically or horizontally. Since the spigot is sealed until you press the lever, there’s no risk of water leaking out. You can also stack the units together to save space.

Easily Portable

The shape, size, and built-in handle of Reliance Products’ water jug makes it easy to take on the go. While you’d need multiple to establish a potable water supply in an emergency, the seven-gallon size is handy for moving and maneuvering.

Opaque Design Protects Water

Even if your water isn’t stored in complete darkness, the opacity of the jugs can help block UV light. This means safer potable water if you need to store it over a longer period. The “hideaway” spigot also detaches, so you can store the jugs indefinitely without keeping the spigot attached.

The caps appear to be compared with the containers themselves


  • Portable with two built-in handles
  • Stores vertically or horizontally
  • Detachable spigot for storage
  • Easy to maneuver since it holds seven gallons

Materials: 100% Polyethylene

Features: BPA Free Plastic

Rugged Design

Wherever you need to fill, transport, and store your water, Norwesco’s rugged tank can withstand whatever abuse you throw at it. Its dense polyethylene is also shaped so you can use tie-downs to strap the tank down during transport or while filling it.

Standalone Style

If you need to place your water storage tank in a basement, garage, or elsewhere, its standalone style is a benefit. It stands upright on “feet” for a stable installation wherever you need to set it up. Of course, transporting it will be the challenging part.

Compatible with Hoses and Fittings

While the Norwesco 35-gallon tank doesn’t come with fittings, it’s compatible with standard hoses and other connectors. You can attach water filtration systems or pipe water through to your sink or another outlet. Filling and emptying the tank is simple, too, with a top lid and bottom spigot area.


  • Rugged polyethylene design
  • Molded spots for straps to tie it down
  • Top filling port plus a lower spigot area
  • Compatible with water hoses and other accessories
  • Transparent so you can easily check water levels

7. Augason Farms Water Storage Barrel 55-Gallon Drum

Augason Farms Barrel 55-Gallon


  • Up To 30 Days Of Restoration
  • Meets Strict EPA Guidelines
  • Perfect For Emergency Food Or Water Storage
  • Leaves No Unpleasant Aftertaste

Materials: 100% Food-Grade Polyethylene

Features: BPA Free Plastic

Food-grade Polyethylene Construction

This large-scale water storage drum looks rugged, but its materials are food-grade. You can securely store 55 gallons of clean water without worrying about BPA or other byproducts of plastic.

Two Plug Fittings

Whether you want to drink the water or drain the reservoir, two plug fittings let you access your reserves. The tank is sealed up, but you can add a spigot, hose, or another accessory to drain water or create a tap system for drinking water or other uses.

High-Capacity with Water-Safe Structure

It can be tough to find a water-safe drum of this size, but Augason’s barrel is food-safe and has a high capacity. Not only is the unit safe for drinking water, but it’s also a solid color, which helps prevent light from reaching your water supply.


  • Holds 55 gallons—almost enough water for an entire month for two people
  • Is opaque so light won’t affect your water safety or quality
  • Has two convenient drain holes (with optional seals) to access water
  • Compatible with pumps and faucets for easier water access


  • The top is not removable, so the unit can be hard to sanitize
  • You’ll have a hard time seeing inside to check water levels
  • Moving a 55-gallon drum full of water isn’t easy
  • You need a torque wrench to open one of the water valves (bung cap holes)

8. Eagle 1610MB Blue High Density Polyethylene Lab Pack Drum with Metal Lever-Lock Lid, 14 Gallon Capacity

You could also secure food items with this type of container.

Removable Lid

While some water storage containers are pump-in, pump-out, the entire lid comes off the Eagle lab pack drum. With the metal lever-lock ring on top, you can rest assured that your water won’t go anywhere. Of course, you need to lock on the lid securely each time you open or close the bucket.

Easy to Clean

Since the entire lid comes off, this storage drum is easy to clean. Its wide-mouth design lets you sanitize or scrub as necessary. Plus, the high-density material can handle industry-grade sanitizing products, too.

Designed for Potable Water Storage

Specially designed for potable water storage, the WECO tank is uniquely configured for drinking water. It’s made of polyethylene (blue, which blocks UV rays) and has a vented manway, too.

Unlike some tanks that need horizontal floor space, the WECO tank stands upright—a lot like a water heater. It’s cylinder shape and small footprint mean it can fit inside your home or garage without taking up much space.


  • Meets FDA regulations for potable water storage
  • Comes with fittings to install
  • Stands vertically and doesn’t take much floor space
  • Has a high capacity for whole-property water storage


  • Takes a long time to fill/refill
  • May be challenging to sanitize since it has only one inlet and one outlet

Easy to Clean/Sanitize

Since the top of the Igloo cooler comes off completely, it’s easy to rinse out and even sanitize. The shape and size also lends itself to dumping water out the top, if you need to, in order to clean or sanitize. You can also use other beverages in the cooler without worrying about being able to properly clean afterward.

No Additional Equipment Necessary

Since the cooler is a water cooler itself, you don’t need additional equipment to use it for your potable water (or other beverages). The bottom spigot allows you to access fresh water, while the top lid allows easier and faster pouring as necessary.


  • Easy to transport since it’s a small size
  • Simple to clean since it has a removable lid
  • Built for water and beverage dispensing
  • Built-in handles for portability
  • Stackable even while dispensing
  • Insulates against heat for short durations

  • Durable material for backpacking and other rugged conditions
  • Compatible with many water filter add-ons
  • Lifetime warranty
  • Variable temperature compatibility

Final Verdict

Smart Tank Stackable Water Storage Tank

When you need to store a lot of potable water, protect it from UV damage, and have easy access, there’s one excellent solution: the Smart Tank 50 Gallon Stackable Water Storage Tank.

It’s our top pick because it holds 50 gallons of water but offers handy perks of smaller storage containers. Once you fill your tank, you can easily access the water whenever you need it. Plus, you can stack these units to create the H2O stockpile your household needs.As far as water safety, the ability to block UV rays is a top concern for water safety. Other tanks offer visibility so you can check water levels, but the Smart Tank protects your water from damage while keeping it secure and healthy.

How to Pick the Perfect One for Your Needs

When it comes to the best water storage containers, think about the following points. Planning ahead might help you avoid buying the wrong type of storage container for your water.

Planned Water Usage

If you’re storing drinking water, that’s vastly different than storing water for washing clothes or flushing the toilet.

So, the first consideration is what type of water you need to store. If you’re stowing drinking water, you want food-safe materials and an easy way to get the water out of the container.

In contrast, if you’re setting aside water for other household purposes, the sterility of the container won’t matter as much. It may not even matter if anything is leaching into the container—whether from plastic or corroded metal—if you don’t plan to drink the water.

Length of Water Storage

Emergency water storage is a smart idea, but how long can you actually store water? Per the FDA, “there is no limit to the shelf life of bottled water,” notes the International Bottled Water Association.

Properly sealed water stored in cool conditions away from sunlight is good for more than two years, the IBWA explains. However, this applies to professionally bottled water, since it’s produced under “sanitary” manufacturing practices.

Water Storage Container Size

The size of your ideal water storage container depends on your planned usage for it. Large water containers are helpful for storing H2O reserves for an entire household, while smaller options may get you through a few days of an emergency.

Along with considering how and when you might need your stored water, you also need to plan where you’ll store it. To that end, a larger container may not make as much sense as multiple, smaller containers.

Think about how much water you want to store and where you plan to keep it to determine the appropriate container size.

Where to Buy Water Storage Containers

Typically, you can buy water storage containers at feed supply and hardware stores. However, you may not be able to find emergency water storage containers at your local retailers. Fortunately, shopping online is often an ideal way to buy a water storage container.

The benefits of water storage are practically endless.

  • Drinking water storage containers ensure you never run out of potable water.
  • Large water storage containers can equip you for emergencies.
  • Keeping water nearby eliminates the need to travel during a crisis.
  • You don’t need to purchase bottled water for any reason.
  • You can filter the water using methods you know and trust.
  • You won’t need to spend money to find safe water in an emergency.
  • It’s more convenient to store water in big batches rather than run the tap to refill more frequently.
  • Bottling your own water can be safer than using plastic bottles from a manufacturer.
  • You can be self-sufficient and not need stores to supply your water.
  • With at-home filtration systems, you can use and refill the containers as many times as you want.
  • Stored water doesn’t lose its value or healthy properties.
  • You know exactly how long you can go before replenishing emergency supplies, by calculating the water storage and your household’s consumption.
  • You won’t be impacted by short-term water shutoffs in your neighborhood.
  • You won’t pay for water delivery or any type of commercial maintenance.


Here are commonly asked questions about water storage containers.

a. How long can you store water in a container?

The FDA says there’s no shelf life for water. Whether you have a large water tank or smaller plastic water containers, there is technically no limit to how long it’s “good.”

That said, commercially bottled water uses sanitary practices for bottling. At home, you may not be able to replicate the safety of water bottling.

b. What is the best way to store drinking water long term?

The FDA says that the best way to store drinking water long-term is by keeping it in food-safe containers in a temperature-controlled environment. You want cooler temperatures and preferably a darker space—like your pantry—to store drinking water.

c. Is it safe to store water in a plastic container?

The short answer is that it depends on the type of container. You want a BPA-free container with as few potential toxins as possible. But plastic (and plastic-type material) can be a safe way to store water, if you do your research.

d. How often should water tanks be cleaned?

How often you clean the water tanks depends on how often you refill and reuse them. Keep an eye out for any mold growth or other problems—and clean them if you see any issues.
