More Details on Our Top Picks

  1. WaterBrick International WaterBrick Water Storage Containers for Emergency Water Storage | 6-Pack of Stackable 3.5 Gallon Water Container Bricks | Food-Grade HDPE Plastic | BPA-Free | STD Blue

    This set of six WaterBrick containers stands out for their innovative stackable design, which allows for versatile storage in tight spaces, unlike bulkier tanks that require dedicated room. Their 3.5-gallon capacity per brick makes them ideal for those who need modular, portable water storage that can double as furniture or be stored discreetly. Compared to larger tanks like the Augason Farms 55-Gallon Barrel, these are less suited for households needing high volume, but excel in adaptability and space efficiency. The BPA-free, food-grade HDPE ensures safety for long-term storage, although their smaller size means you need more units to reach the same capacity. These containers are perfect for preppers, RV owners, or campers who prioritize flexibility over volume. Tradeoffs include needing multiple units for large-scale storage and slightly more complex organization.

    Pros:
    • Highly stackable and space-efficient design
    • Made from BPA-free, food-grade HDPE plastic
    • Lightweight and portable with handles on each brick
    Cons:
    • Limited capacity per container, requiring multiple units for large needs
    • Less suitable for storing large volumes in a single tank

    Best for: Preppers and outdoor enthusiasts who need flexible, space-efficient water storage.

    Not ideal for: Large families or those seeking high-capacity tanks for long-term water storage without frequent refills.

    • Capacity per container:3.5 gallons
    • Number of containers:6
    • Material:Food-grade HDPE
    • Dimensions:9″ W x 18″ L x 6″ H
    • BPA-Free:Yes
    • Stackability:Yes

    Bottom line: This pick is ideal for users who need customizable, space-conscious water storage solutions for limited spaces or mobility needs.

  2. Water Preserver for 55 Gallon Water Tank – Purifies Water for Drinking for 5 Years – Ideal for Emergency Water Storage or Rain Collection – Survival Kit, Earthquake, Hurricane, Emergency Water-2 Pack

    This Water Preserver offers a reliable method to keep stored water safe for up to five years, surpassing the lifespan of typical chemical treatments like iodine tablets. Unlike larger tanks such as the Augason Farms 55-Gallon Barrel, which focus on volume, this product emphasizes water safety and purity, making it a smart addition for long-term preparedness. It’s compatible with all common storage containers, from small jugs to large barrels, providing versatility for different setups. The formula is EPA-licensed and easy to use—just a few drops treat large amounts of water—though it requires careful handling and storage of the bottles. This product is best for preppers and disaster kit builders who prioritize water safety over capacity. Tradeoffs include ongoing costs for refilling and replacing the preservers over many years.

    Pros:
    • Purifies water for up to 5 years per treatment
    • EPA-licensed, proven formula
    • Compatible with various container sizes
    Cons:
    • Requires careful handling and storage of preservers
    • Ongoing cost for replacement bottles over time

    Best for: Homestead preppers or disaster readiness planners focused on maintaining long-term, safe drinking water.

    Not ideal for: Casual campers or small households that only need short-term water treatment solutions.

    • Purification lifespan:up to 5 years
    • Quantity:2 bottles
    • Application:5 gallons per bottle
    • EPA licensed:Yes
    • Usage:Long-term storage

    Bottom line: This product is best suited for those who want to preserve long-term drinking water safely and reliably, despite needing to monitor supply replacements.

  3. 5-Gallon Stackable Water Storage Containers, 5 Gallons Each w/Lids + Spigot, Easy Fill, Survial Supply Emergency Water Storage for Camping and Disaster Preparedness, RV, 30 Gallon (6 Tanks)

    This 6-pack of 5-gallon tanks offers a practical solution for those with limited space who need moderate water capacity and easy access. The inclusion of spigots simplifies dispensing, making them well-suited for daily use during emergencies or outdoor activities. Compared to larger tanks like the Augason Farms 55-Gallon Barrel, these are more manageable for small spaces and quick setup, though they lack the volume for prolonged storage without multiple units. Their sturdy, leak-proof design and USA-made quality ensure durability, but stacking can be cumbersome if space is tight or uneven. These tanks are an excellent choice for RV owners, small households, or anyone seeking modular, portable storage that’s straightforward to fill and use. Tradeoffs include needing multiple units for large-scale storage and managing stacking safety.

    Pros:
    • Includes spigot for easy dispensing
    • Made in USA with durable materials
    • Stackable and easy to transport
    Cons:
    • Limited capacity per tank, requiring multiple units for high volume needs
    • Stacking can be unstable if not carefully arranged

    Best for: RV travelers, small households, or preppers needing flexible, portable water storage.

    Not ideal for: Large families or long-term storage where high capacity is essential without frequent refills.

    • Capacity per tank:5 gallons
    • Number of tanks:6
    • Material:Food-grade plastic
    • Includes:Lids and spigot
    • Made in:USA
    • Dimensions:Designed for stacking

    Bottom line: This set is ideal for those who prioritize portability and easy access over large-scale water storage capacity.

  4. WaterPrepared Portable Water Tank, Plastic Handle & Hose Spigot, 35 Gallon, Blue – Heavy-Duty Beverage and Hydration Dispenser for Outdoor and Camping Trip

    The WaterPrepared 35-gallon tank excels in outdoor environments where portability and ruggedness matter most. Its UV-proof plastic guards against sun damage, a feature that larger, stationary tanks like the 55-Gallon Augason drum don’t emphasize. The integrated spigot and garden hose connection facilitate quick water access, ideal for camping, hiking, or emergency outdoor setups. While its lightweight design (only 16 pounds empty) makes it easy to move, the tank’s horizontal shape limits vertical storage options, making it less suitable for compact indoor spaces. It’s best for outdoor adventurers or emergency outdoor hydration, not for permanent indoor storage. Tradeoffs include less suitability for long-term indoor storage and limited capacity compared to larger barrels.

    Pros:
    • UV-proof plastic resists sun damage
    • Lightweight and portable with handles
    • Includes garden hose compatible spigot
    Cons:
    • Horizontal shape limits vertical storage options
    • Limited capacity for large-scale storage

    Best for: Outdoor enthusiasts, campers, or emergency preppers needing portable, durable outdoor water storage.

    Not ideal for: Households seeking a permanent, high-capacity indoor water storage solution.

    • Capacity:35 gallons
    • Material:UV-resistant plastic
    • Weight empty:16 pounds
    • Includes:Hose spigot
    • Shape:Horizontal
    • UV protection:Yes

    Bottom line: This tank is perfect for outdoor use where mobility and durability are paramount, but less suited for indoor long-term storage.

  5. Augason Farms 55-Gallon Water Storage Barrel – BPA-Free Plastic Barrel – Emergency Water Storage Drum for Home Preparedness

    The Augason Farms 55-Gallon Barrel offers a straightforward, large-volume solution for long-term water storage, ideal for households seeking a reliable backup. Its sturdy, BPA-free polyethylene construction ensures water safety and durability over multiple seasons. Compared to smaller, stackable options like the WaterBrick, this tank provides a more centralized and less cluttered storage method, making it suitable for basements or dedicated storage rooms. Two built-in ports facilitate filling and draining, simplifying maintenance. However, its bulkiness makes it less flexible for irregular spaces or quick mobility. This model is well-suited for families or communities aiming for substantial volume with minimal handling. Tradeoffs include the large footprint and less portability, making it less ideal for limited spaces or frequent relocation.

    Pros:
    • Large 55-gallon capacity for extended storage
    • Made from BPA-free, durable plastic
    • Two accessible fill/drain ports
    Cons:
    • Heavy and bulky, difficult to move once filled
    • Requires significant space for storage

    Best for: Families or community groups planning for long-term, high-volume water backup in a fixed location.

    Not ideal for: Individuals with limited space or those needing portable, easy-to-move containers for outdoor use.

    • Capacity:55 gallons
    • Material:BPA-free polyethylene
    • Dimensions:Standard large barrel size
    • Ports:2
    • Lid type:Secure screw-on
    • Design:Heavy-duty, durable

    Bottom line: This barrel is best for households seeking a high-capacity, durable, long-term water storage solution in a fixed space.

  6. 55 Gallon Stackable Emergency Water Storage Tank for Long-Term Drinking Water Heavy-Duty Water Barrel

    This 55-gallon tank excels in combining large capacity with a space-efficient, stackable design, making it ideal for long-term water storage in garages or basements. Compared with the smaller 30-gallon tank, it provides nearly double the water, reducing the need for multiple units, though it involves a heavier initial setup. Its rotationally molded polyethylene construction guarantees decades of use, offering peace of mind during emergencies. A large twist lid simplifies filling and cleaning, and the built-in brass spigot ensures reliable dispensing. While its size might be cumbersome for very tight spaces, the robust build and high capacity make this a top choice for families looking to stock significant water reserves. The only tradeoff is the larger footprint and heavier weight when full, which may limit portability.

    Pros:
    • Large 55-gallon capacity for extended emergency preparedness
    • Space-saving stackable design maximizes storage efficiency
    • Heavy-duty rotationally molded polyethylene for decades of use
    • Easy filling, cleaning, and dispensing with a large twist lid and brass spigot
    Cons:
    • Size and weight can be challenging for limited spaces or mobility
    • Requires a dedicated, stable location due to its bulk

    Best for: Families needing a high-capacity, long-term storage solution in a dedicated space like a garage or basement.

    Not ideal for: Individuals in small apartments or those needing portable units for frequent movement, due to its size and weight.

    • Capacity:55 Gallons
    • Material Type:Rotationally molded polyethylene
    • Dimensions:21″L x 21″W x 21″H
    • Weight:24 Pounds
    • Shape:Square
    • Color:Blue

    Bottom line: This tank is ideal for those with ample space seeking a durable, high-capacity long-term water storage solution.

  7. WaterPrepared Stackable Plastic Drinking Water Storage Tank with Spigots, 55 Gallon, Blue – Portable Emergency Hydration Container for Survival or Disaster Preparedness

    This 55-gallon tank stands out for its portability, thanks to a lighter weight and integrated handles, making it suitable for emergency situations where moving supplies is necessary. It’s comparable in capacity to the BayTec 55-Gallon Barrel, but with a focus on ease of transport and stacking flexibility. Its BPA-free, UV-proof HDPE construction maintains water quality over time, and the built-in spigots facilitate quick dispensing for drinking, cooking, or cleaning. Its blue color allows quick identification in storage. However, its lightweight design might feel less sturdy under heavy use, and it lacks the ruggedness of rotationally molded tanks. This makes it better suited for those who prioritize mobility and ease of setup over maximum durability.

    Pros:
    • Lighter weight for easier handling and repositioning
    • Built-in handles for quick transport and stacking
    • UV-proof, BPA-free HDPE maintains water safety
    • Secure, space-efficient stacking design
    Cons:
    • Less rugged than rotationally molded tanks, potentially less durable over decades
    • Lightweight design may feel less sturdy under heavy use

    Best for: Hikers, campers, or homeowners needing a large, portable water container for short- or long-term use that can be moved easily.

    Not ideal for: People with permanent, dedicated water storage locations who do not need frequent relocation, as its lighter construction offers less durability.

    • Capacity:55 Gallons
    • Material Type:BPA-Free HDPE
    • Dimensions:Approximately 23″ x 23″ x 35″
    • Color:Blue
    • Features:Built-in spigots, stacking grooves
    • Weight:Varies (lighter than rotational tanks)

    Bottom line: Ideal for those who need a sizable, portable water storage option that balances ease of handling with sufficient capacity.

  8. 5-Gallon Stackable Water Storage Containers, Emergency Water Storage for Camping and Disaster Preparedness, 20 Gallons

    This set of four 5-gallon containers offers a flexible, lightweight solution for short-term water needs, perfect for camping or small household emergency kits. While each tank is easy to move and stack, their smaller capacity means you’ll need multiple units for a substantial reserve, unlike the 55-gallon tanks. The flat top and bottom facilitate stacking, and the handles make transport straightforward. Made from BPA-free HDPE, these containers ensure water safety and durability. Their compact size makes them ideal for those with limited space or for quick deployment, but they do require multiple units to meet long-term needs. The tradeoff is the need for more storage units and potential complexity in managing several smaller tanks instead of one large bulk container.

    Pros:
    • Lightweight and easy to transport
    • Stackable with flat tops and bottoms
    • Includes lids for secure sealing
    • Made from food-grade, BPA-free HDPE
    Cons:
    • Limited capacity per container, requiring multiple units for large storage
    • Less space-efficient than a single large tank for long-term storage

    Best for: Individuals or families seeking a portable, modular water supply for short-term or mobile emergency preparedness.

    Not ideal for: Homeowners with ample space who prefer a single, large storage tank for long-term needs, as these are better suited for short-term use.

    • Capacity per tank:5 Gallons
    • Number of units:4
    • Material Type:BPA-Free HDPE
    • Total capacity:20 Gallons
    • Features:Lids, handles, stackable design
    • Dimensions:Each approx. 12″ x 12″ x 16″

    Bottom line: Best suited for those needing flexible, portable water storage in manageable units for short-term or outdoor use.

  9. 30 Gallon Stackable Emergency Water Storage Tank – Heavy-Duty Water Barrel for Long-Term Drinking Water or Preparedness

    This 30-gallon tank offers a compact yet robust option for homes with limited space, providing approximately one week of water for a family of four. Its stackable design allows for vertical expansion, making it a good choice for small garages, closets, or RVs. Made from food-grade, BPA-free rotationally molded polyethylene, it promises durability and safety over long-term use. The large twist lid simplifies filling and cleaning, and the built-in spigot ensures quick access to stored water. Compared to the 55-gallon tanks, this smaller version is more manageable in tight spaces but offers less capacity, requiring more units for extensive storage. Its size and weight are ideal for smaller households or those with spatial constraints.

    Pros:
    • Compact size suitable for small spaces
    • Stackable to increase storage vertically
    • Made from durable, food-grade polyethylene
    • Easy to fill and drain with large twist lid and spigot
    Cons:
    • Limited capacity compared to larger tanks, requiring multiple units
    • Less suitable for long-term storage without expansion

    Best for: Small households, apartments, or RV owners who need a reliable, space-efficient water reserve for short- to medium-term emergencies.

    Not ideal for: Those seeking maximum long-term storage capacity or with ample space for larger tanks, as it may require multiple units for extended preparedness.

    • Capacity:30 Gallons
    • Material Type:Rotationally molded polyethylene
    • Dimensions:21″L x 21″W x 21″H
    • Weight:17 Pounds

    • Color:Blue

    Bottom line: This tank is well-suited for small households or mobile setups needing dependable, space-efficient water storage.

  10. 55 Gallon Blue Water Barrel | Solid Mold | 2 Inch Bung Holes, Good for Long Term Drinking Water Use | BPA Free

    This 55-gallon barrel from Mauser offers a rugged, reliable solution for long-term water storage, especially for those who prioritize durability and chemical resistance. Its solid mold design with 2-inch bung holes makes it suitable for gravity-fed dispensing or connection to filtration systems. As a BPA-free, high-density polyethylene container, it ensures water safety over years of storage, comparable to the WaterPrepared 55-Gallon Barrel. Its heavy-duty construction is ideal for outdoor or off-grid locations, but it may be heavier and less stackable than rotational tanks. The straightforward design emphasizes longevity and chemical compatibility, making it a strong choice for serious preppers or long-term storage needs.

    Pros:
    • Heavy-duty, solid mold construction for longevity
    • 2-inch bung holes for easy filling and dispensing
    • BPA-free, chemical-resistant HDPE material
    • Suitable for long-term outdoor storage
    Cons:
    • Heavier and less stackable than rotational tanks
    • Bulkier and takes up more space in indoor settings

    Best for: Preppers and homeowners seeking a durable, long-lasting water barrel for outdoor or off-grid use, requiring minimal maintenance over years.

    Not ideal for: Indoor or space-constrained environments where stacking or compact size is a priority, as this barrel is primarily designed for durability and outdoor use.

    • Capacity:55 Gallons
    • Material Type:High-Density Polyethylene (HDPE)
    • Dimensions:23″ x 23″ x 35″
    • Weight:22 lbs

    • Color:Blue

    Bottom line: This barrel is perfect for those needing a rugged, long-term outdoor water storage solution with minimal maintenance.

  11. 5-Gallon Stackable Water Storage Containers, Water Treatment,5 Gallons Each w/Lids + Spigot, Easy Fill, Survial Supply Emergency Water Storage for Disaster Preparedness, 20 Gallon (4 Tanks)

    This set of 5-gallon containers excels in portability and space efficiency, thanks to their flat, stackable design and integrated handles. Compared with larger tanks like the Legacy Food Storage units, these are easier to move and store in tight spaces, making them ideal for quick deployment during emergencies. The BPA-free HDPE plastic ensures safety and durability, while the twist spigots facilitate controlled pouring without air locks, a common issue in bulk tanks. However, their smaller capacity means you’ll need multiple units for long-term storage, which can add to cost and complexity. These containers are best suited for families needing flexible, transportable water solutions or for supplementing larger tanks. They are less ideal for those seeking a single, large storage solution for long-term, in-place use.

    Pros:
    • Compact, stackable design saves space
    • Includes built-in spigot for easy dispensing
    • Made from food-grade, BPA-free HDPE plastic
    Cons:
    • Limited 5-gallon capacity per tank requires multiple units for large storage needs
    • Not designed for permanent, in-place long-term storage

    Best for: Families who need portable, easy-to-move water storage for emergency preparedness or outdoor trips.

    Not ideal for: Homeowners seeking a large, single tank for long-term in-place storage, as these are meant for quick, flexible use.

    • Capacity:5 gallons per tank
    • Material:100% food-grade HDPE plastic
    • Dimensions:Not specified
    • Stackability:Yes
    • Includes:Lids, spigot
    • Weight:Approximate 1.5 lbs per tank

    Bottom line: This pick is ideal for those prioritizing portability and space efficiency in emergency water plans.

  12. Legacy Food Storage Emergency Water Storage Containers, Long Term 5 Gallon Water Tank – 4 Stackable Food Grade Tanks Included, for Camping, Prepping, Survival – 20 Gallon Total Capacity

    This set of four 5-gallon tanks is designed specifically for long-term storage, with features that prevent water degradation over time. Unlike the portable containers from the first product, the Legacy tanks are heavier and less mobile, but they excel in space-efficient, in-place storage thanks to their stackable ribs and dark blue, light-blocking exterior. This makes them suitable for garage or basement storage where long-term preservation is a priority. The large spigot and vent cap facilitate easy, controlled pouring, similar to the smaller containers but with added durability. The main tradeoff is their weight and bulk, which makes them less suitable for frequent transport or quick deployment. This option makes the most sense for individuals planning for extended crisis scenarios, where water quality preservation is critical.

    Pros:
    • Designed for long-term storage with light-blocking exterior
    • Stackable ribs for secure, space-saving stacking
    • Includes spigot and vent cap for smooth pouring
    Cons:
    • Heavy and less portable, not ideal for frequent movement
    • Requires significant space for full stack of tanks

    Best for: Preparedness-minded individuals seeking durable, long-term water storage that minimizes light exposure and fits into tight spaces.

    Not ideal for: Users who need portable, easily movable water containers for short-term use or frequent transport, due to their weight and bulk.

    • Capacity:4 tanks of 5 gallons each, total 20 gallons
    • Material:BPA-free food-grade plastic
    • Dimensions:15″ x 10″ x 12″ per tank
    • Color:Dark blue
    • Features:Stackable ribs, light-blocking exterior, spigot, vent cap
    • Weight:Approx. 40 lbs per tank when full

    Bottom line: This set is perfect for those prioritizing long-term preservation and space-efficient, in-place storage over portability.

In evaluating these products, I focused on key criteria that impact long-term reliability and user safety. Capacity was a primary factor, ensuring options suit both small-scale and large-scale preparedness. Materials and construction quality were scrutinized to guarantee water safety over extended periods, prioritizing food-grade, BPA-free plastics. Ease of use, such as spigots and stackability, was also considered to support long-term maintenance and space efficiency. Cost-effectiveness and durability influenced the ranking, with an eye toward products offering the best balance of quality and value for different types of users.

Factors to Consider When Choosing Best Long Term Water Storage Tank For Home Preparedness

Choosing the right long term water storage tank involves balancing capacity, durability, safety, and usability. Beyond initial costs, consider how much water you need, where you’ll store the tank, and how often you’ll need to maintain it. Proper selection can prevent contamination, save space, and ensure reliable access during emergencies.

Capacity and Storage Space

Assess your household water needs and available storage space. Larger tanks like 55 gallons provide long-term supply but require significant space and installation effort. Smaller containers, such as 5 or 20 gallons, are easier to handle and store but may require more frequent refills or multiple units. Think about whether your priority is a compact setup or a large, self-sufficient reservoir.

Material and Water Safety

Look for tanks made from food-grade, BPA-free plastics to prevent chemical leaching into stored water. Durable materials that resist UV degradation and corrosion ensure the water remains safe over years. Cheaper plastics may degrade quickly or introduce contaminants, so investing in quality materials pays off in safety and longevity.

Ease of Use and Maintenance

Features like built-in spigots, wide openings for cleaning, and stackable designs simplify ongoing maintenance. Tanks that are difficult to clean or refill can lead to mold or algae growth over time, compromising water safety. Consider how easy it is to access, clean, and refill the tank, especially for long-term storage scenarios.

Portability and Installation

If you need a portable solution for outdoor or off-grid use, choose tanks with handles or lightweight construction. For permanent installations, larger, heavier tanks with secure mounting options are better. Weigh the benefits of mobility against stability and space constraints to match your setup.

Cost and Long-Term Value

While premium tanks may cost more upfront, they often offer longer warranties and higher-quality materials, reducing replacement frequency. Budget options can work well if properly maintained, but beware of tanks that degrade or leak prematurely. Balance your budget with the anticipated lifespan and safety features to maximize value.

Frequently Asked Questions

How long can water safely be stored in these tanks?

Most food-grade tanks can store water safely for 6 months to a year with proper treatment and maintenance, but tanks designed for long-term preservation, like those with preservatives or sealed systems, can hold water for up to 5 years or more. Regular inspection, cleaning, and water treatment are essential to maintain safety during extended storage periods.

What maintenance is required for long-term water storage tanks?

Routine maintenance includes cleaning the interior of the tank, checking for leaks or cracks, and refilling or replacing water as needed. Using water stabilizers or preservatives can extend shelf life, while ensuring the spigots and lids are sealed tightly prevents contamination. Proper maintenance significantly extends the usability and safety of your stored water.

Are stackable tanks better than single large tanks?

Stackable tanks offer flexibility and space efficiency, making them ideal for limited storage areas or situations where you want to expand capacity gradually. However, they may require more maintenance and careful stacking to prevent tipping or leaks. Large, single tanks tend to be more stable and easier to manage but need more space and a sturdy installation location.

Is it better to choose tanks with spigots or without?

Tanks with built-in spigots simplify dispensing and reduce the risk of contamination during transfer. They make regular use more convenient, especially for long-term storage where frequent access is needed. Tanks without spigots may be cheaper initially but require additional fittings and more effort during refilling and dispensing, making them less user-friendly over time.

How do I select the right capacity for my household?

Estimate your household’s daily water usage and multiply by the number of days you want to be self-sufficient—typically 3 to 14 days for emergency preparedness. Larger families or those with specific needs should opt for bigger tanks, while singles or couples may find smaller sizes sufficient. Balancing capacity with available storage space helps ensure you are prepared without overcommitting space or budget.

Conclusion

The best overall choice for most households is the WaterPreserver 55-Gallon Tank thanks to its long-term preservation capabilities and durability. For those seeking affordability and ease of use, the WaterBrick 6-Pack offers a versatile, space-efficient solution. Beginners or small families can start with 5-gallon containers, while larger setups or off-grid users might prefer the heavy-duty, stackable 55-gallon drums. For premium buyers prioritizing safety and longevity, investing in high-quality, BPA-free tanks remains the best route. Match your specific needs, space, and budget to find the perfect long-term water storage solution for your home preparedness plan.
