How to Choose the Best Water Storage Containers for Your Home

How to Choose the Best Water Storage Containers
for Your Home

While we can never store enough water, there is a limit on how much we feasibly can store. Larger containers are more useful for long-term storage but are treated differently. You must first decide where your long-term water storage is going to be placed before you select which containers to buy. The more room you have, the bigger container options become available to you.

Selecting storage locations

Assess your storage space for the following:

  • Should provide optimal conditions that are cool, dry, and dark. Light exposure promotes organism growth, quickly reducing your water storage time.

  • Larger spaces can include basements, cellars, and garages.
  • Garages must be used with caution as temperatures fluctuate dramatically. Make plans to block the light and rotate your water storage every six months even if you are using a water preserver.

  • Storing water in small spaces like apartments can be challenging, but innovative solutions are available. Choosing the right spots can help you store water without visible clutter. Learn more about storing water in limited spaces.

Long-Term Water Storage
Water Container Options

Once you’ve chosen the best places that offer the best conditions, you can move on to finding the containers that serve your space the best. The more space, the more storage container options there are to choose from.

Long-term water storage containers come in heavy-duty food-grade plastic, glass, or stainless steel. For long-term storage, some experts recommend heavy-duty BPA-free plastic, as plastic is more durable and easier to handle. The plastic containers listed here are not the only ones available, but they are some of the most popular.

Long-Term Water Storage
Which Options Are Right For You?

Bathtub Water Liner

Plastic water storage containers, such as WaterBob and AquaPod, are designed to hold large volumes of water safely and are made from durable, food-grade plastic to ensure water remains clean and uncontaminated. When needed, place it in your bathtub and fill it with water. It is a one-time use product, however, its ability to store large amounts of water due to its unique application makes this a powerful, yet affordable storage option.

Holds: up to 100 gallons of water

3.5 Gallon Water Bricks

Water bricks work best for smaller spaces. They can be stored in tight spaces under couches, beds, or in closets. They are great if you need that flexibility. They also stack so you can store more with less floor space required. These are the easiest to use and transport.

Weight when full: 29.2 lbs.
Accessories needed: water spigot

5 / 7 / 15 Gallon Water Jugs

These containers are very sturdy and made of food-grade plastic, which is a must, and most are stackable. The blue color helps to restrict light exposure, preventing algae growth. You must consider thickness before you buy one if you are interested in stacking them. The thicker, stackable ones cost more but this is great for limited space.

Weight when full: 5g = 41.7 lbs., 7g = 58.4 lbs. / 15g = 125.2 lbs.
Accessories needed: water spigot

20 Gallon Containers

The 20-gallon water container is a portable, space-saving water storage solution. This container is stackable up to three high and has built-in handles that make it easy to move. This serves as a middle option between 5-gallon and 55-gallon containers and is a good choice for apartments and other small spaces.

Weight when full: 166.8 lbs.
Accessories needed: bung wrench & siphon hose

55 Gallon Barrels

These units are standard in the shipping industry for all kinds of goods. If you go this route, make sure you purchase one specifically for water storage. This gives you the ability to store more with less floor space and is one of the most popular water storage options on the market today.

Larger Drums & Tanks

Larger size drums and tanks are efficient at storing larger quantities of water. They come in different sizes, anywhere from 160 gallon to 500-gallon tanks, and even larger. In some cases, the larger the tank the more money you will save. The price break is unbelievable when comparing the same amount of water stored in 5-gallon containers. Some models may include a detachable spigot.

Weight when full: varies at 8.34 lbs. per gallon.
Accessories needed: none - but an optional pump can be purchased.

Outdoor Barrel System

An outdoor barrel system allows you to store at least 30 gallons of non-stagnant water by continuously rotating the water. These systems are typically UV-resistant, meaning they are designed to withstand sunlight, unlike most other containers that require protection from light exposure. While sun exposure is fine with these specialized systems, it's important to use food-grade hoses to ensure water safety.

Weight when full (at 30 gallons): 250.2 lbs.

Cistern

Cisterns are specifically designed for collecting and storing rainwater, often used for irrigation, household use, and emergency water supply. These systems can collect water from multiple downspouts and have a much larger capacity, typically ranging from 1,000 to 10,000 gallons or more. Cisterns require regular maintenance and water testing.

Accessories needed: Pump and hose for extraction

Plastic Suitable For Storing Water

Now that you know what type of containers you want to buy, here are a few pointers when looking for a reputable vendor. Remember, not all plastic is created equal when it comes to water storage.

Buying the right type of water container

What to look for when buying

  • Look for food-grade containers – they are explicitly labeled by responsible vendors, ensuring they meet safety standards for storing consumables including water.
  • They are made from BPA free, HDPE (high density polyethylene) food grade plastic. Glass and
  • They are often blue and opaque so light cannot get through easily.
  • Ensure the container comes with a secure, airtight lid to prevent contamination and keep water fresh for long-term storage.

What not to buy or use

Helpful tips

  • Avoid non-food-grade containers, especially those with recycling codes #3 (PVC) and #6 (PS), as they can leach harmful chemicals into stored water.
  • 1-gallon plastic containers and empty soda bottles from grocery stores are not suitable for long-term storage. Their plastic can degrade, crack, or leach chemicals over time. They should only be used for short-term rotation.
  • Never use damaged, old, or unknown containers, as they may compromise water quality. If a container’s previous use is unclear, it’s best to avoid it altogether.
  • Do not buy used food containers from online marketplaces like Craigslist or eBay unless you personally know the seller. Containers may have stored harsh chemicals that do not fully dissipate, leading to potential water contamination.
Water Storage
Storage Conditions

Once you have invested your time and money, this last step is vital to the success of your long-term storage.

Storage Environment

Choose a location that provides optimal conditions—cool, dry, and dark, with temperatures between 50°F and 70°F. (Note: Garages can become very warm in the summer; consider using your garage only as a last resort, unless you are willing to rotate your water supply every six months.)

Control Light

It is imperative that you minimize the light, or at the very least, direct sunlight. Light exposure promotes organism growth, quickly reducing your water storage time.

Placement

Store your water containers at least 6 inches from the ground. Learn more about water storage placement.
