More Details on Our Top Picks
Reliance Products Aqua-Tainer 7 Gallon Rigid Water Container, Blue
This 7-gallon container stands out for its space-efficient, rectangular shape, which makes it easier to store in tight spaces compared to round tanks. Its molded contour grip and reversible spigot cap enhance handling and convenience during emergency setups or outdoor activities. Unlike larger, bulkier tanks, the Aqua-Tainer is lightweight enough to move easily, but it does have a significant downside: prolonged sunlight exposure can cause degradation, and the plastic may become brittle if not stored properly. Compared to the 5-gallon options, it offers more capacity without taking up excessive space, making it a balanced choice for medium-sized households or groups. However, it’s less suited for prolonged outdoor sun exposure; storing it in shaded areas is essential. This container makes the most sense for those needing a reliable, space-saving emergency water supply that’s easy to handle and store in various environments.
Pros:- Space-saving rectangular design for efficient storage
- Reversible spigot for versatile use
- Molded contour grip simplifies handling
- Suitable for outdoor and emergency use
Cons:- Degrades with prolonged sunlight exposure
- Plastic may become brittle if not stored properly
Best for: Families or individuals who want a durable, space-saving container with easy dispensing for moderate emergency water needs
Not ideal for: Anyone planning to store the container in direct sunlight long-term, as UV exposure can weaken the plastic
- Capacity:7 gallons
- Dimensions:11.3 x 11.0 x 15.3 inches
- Color:Blue
- Material:Rigid plastic
- Warranty:Five-year manufacturer’s warranty
Our verdict“This is an excellent all-around choice for those needing a reliable, easy-to-handle emergency water container that fits into limited storage spaces.”
Legacy Food Storage Emergency Water Storage Containers, 5-Gallon, Pack of 4
This set of four 5-gallon tanks offers a cost-effective solution for long-term water storage, especially when compared to buying single units like the Aqua-Tainer. Their stackable design maximizes storage space, and the dark blue, light-blocking exterior helps keep water fresher for longer. Including water treatment drops adds peace of mind for maintaining water safety over years, unlike simpler containers that lack such features. However, the heavy weight—about 40 pounds per tank when full—can make handling cumbersome, especially for users with limited strength. The assembly required for caps and spigots adds extra steps, but this is a small tradeoff for the long-term benefits. This makes the set ideal for preppers looking to stockpile large quantities of safe, long-lasting water storage on a budget.
Pros:- Includes water treatment drops for extended safety
- Stackable design optimizes storage space
- Light-blocking dark blue color prolongs water freshness
- Easy to pour with spigot and handle
Cons:- Heavy when full, about 40 lbs per tank
- Limited to 5-gallon capacity per tank
- Requires assembly of caps and spigot
Best for: Preppers or households planning for long-term storage with a focus on maximizing space and safety
Not ideal for: Users needing lightweight, portable containers for frequent transport or short-term use
- Capacity:5 gallons per tank
- Total Capacity:20 gallons
- Dimensions:15″ x 10″ x 12″ per tank
- Material:BPA-free food-grade plastic
- Includes:4 tanks, water treatment drops, spigot, caps, handle, strap wrench
Our verdict“This set offers a reliable, space-efficient long-term water storage solution for those prioritizing safety and cost-effectiveness over portability.”
AquaBrick 3 Gallon Long Term Water Storage Container, Stackable, BPA Free, Blue (6)
The AquaBrick excels in offering a compact, stackable solution for those with limited storage space. Its 3-gallon capacity is ideal for small households or individuals who want to store multiple units without sacrificing much space. The leak-proof, BPA-free construction ensures safe water storage, and the stackable design allows for organized, efficient stacking in closets or cabinets. Compared to larger containers like the Aqua-Tainer, it’s less suitable for big families or high-volume needs, but it compensates with easy handling and storage flexibility. The main tradeoff is the limited capacity of each unit, which may require multiple containers for larger needs. This product suits those seeking a lightweight, manageable option for long-term emergency preparedness in confined spaces.
Pros:- Leak-proof and easy to pour
- Stackable for efficient storage
- BPA free and food safe
- Compact size fits in limited storage areas
Cons:- Limited to 3-gallon capacity per container
- Only available in blue color
Best for: Individuals or small households needing space-efficient, long-term water storage solutions
Not ideal for: Families requiring large quantities of water stored in fewer containers for convenience
- Capacity:3 gallons
- Material:BPA Free
- Color:Blue
- Stackable:Yes
Our verdict“This is a practical choice for compact, long-term water storage, especially when space is at a premium.”
Bathtub Emergency Water Storage Bladder Up To 100 Gallon Capacity with Hand Pump – Food Grade, BPA Free
This large bladder transforms your bathtub into a substantial emergency water reservoir, capable of holding up to 100 gallons. Its food-grade, BPA-free material guarantees water safety, while the quick setup—taking about 20 minutes—makes it a practical choice for sudden emergencies. The included hand pump simplifies dispensing, making it easier to access water during crises. Compared with smaller containers, this bladder offers unparalleled capacity, suitable for large families or community needs. The main drawback is its dependency on bathroom space and the fact that it’s for emergency use only; it’s not meant for daily consumption or frequent refilling. Water must be replenished or replaced every 16 weeks, which could be inconvenient for some users. It’s best suited for those who want a large, temporary water reserve that’s easy to set up without permanent modifications.
Pros:- Large capacity suitable for whole families
- Made from food-grade, BPA-free materials
- Easy to install without tools or permanent modifications
- Includes a hand pump for simple dispensing
Cons:- Requires bathtub space and setup time
- Limited to emergency use; water needs replacement every 16 weeks
- Not suitable for daily or regular water needs
Best for: Large households or community emergency preparedness where space in the bathroom is available
Not ideal for: Individuals with limited bathroom space or those requiring daily water access
- Capacity:Up to 100 gallons
- Material:Food-grade, BPA free plastic
- Setup Time:Approximately 20 minutes
- Included:Siphon hand pump
Our verdict“This bladder provides a high-capacity emergency water reserve ideal for large households with available bathroom space.”
5 Gallon Water Jug, BPA-Free Portable Water Dispenser with Spigot for Camping and Emergency Use
This 5-gallon jug combines portability with safety, making it an excellent choice for camping, outdoor activities, or emergency situations. Its lightweight design—just 2.2 pounds empty—makes it easy to carry, unlike heavier, stationary containers. The reinforced, leak-resistant spigot and wide mouth facilitate quick filling and cleaning, improving usability over simpler bottles. While its 5-gallon capacity is suitable for small groups or personal use, it may be insufficient for larger families or prolonged emergencies. The multiple components, like the extension tube and storage bag, add versatility but could be misplaced or require careful handling to prevent leaks. Overall, this jug is perfect for those who need a reliable, portable water source for short-term use or outdoor adventures.
Pros:- Lightweight and portable for outdoor activities
- Made from food-grade, BPA-free materials
- Leak-proof spigot with dust covers
- Wide mouth for easy filling and cleaning
Cons:- Limited to 5-gallon capacity, may be heavy when full
- Spigot may require careful handling to prevent leaks
- Includes multiple components that could be misplaced
Best for: Campers, outdoor enthusiasts, or individuals needing a portable water solution in emergencies
Not ideal for: Large households or long-term storage needs where bigger capacity is required
- Capacity:5 gallons
- Material:PE (food-grade, BPA-free)
- Weight:2.2 lbs
- Spigot:Reinforced, leak-resistant
- Mouth Diameter:3.6 inches
- Includes:Cleaning brush, adjustable spigot, extension tube, storage bag, collapsible water bag
Our verdict“This pick is ideal for outdoor use and short-term emergencies where portability and ease of use are priorities.”
55 Gallon Stackable Emergency Water Storage Tank – Food Grade BPA-Free Water Container for Long-Term Home Preparedness
This 55-gallon tank stands out for its enormous capacity, making it ideal for families preparing for extended emergencies. Its stackable design helps optimize storage space, especially in smaller utility areas, setting it apart from smaller options like the 5-gallon containers. Made from durable, food-grade BPA-free polyethylene, it offers peace of mind about water quality over long periods. However, the sheer weight when full—over 400 pounds—means it’s not suitable for frequent moving without assistance. Its focus on water storage only simplifies maintenance but limits versatility if you need multi-purpose containers. Compared to the Reliance Aqua Tainer, this tank’s capacity far exceeds, but it requires more space and effort to handle. This pick is ideal for homeowners seeking a reliable, long-term solution for large water reserves, willing to invest in heavier, less portable storage.
Pros:- Enormous capacity suitable for extended family needs
- Space-saving stackable design
- Durable, food-grade BPA-free construction
Cons:- Heavy when full, difficult to move alone
- Limited to water storage only, no multi-use functionality
Best for: Families or small communities looking to store substantial water supplies in a compact, stackable format for long-term emergency planning
Not ideal for: Individuals with limited storage space or those needing lightweight, portable containers for frequent transport
- Capacity:55 gallons
- Material:Rotationally molded polyethylene
- BPA-Free:Yes
- Stackable:Yes
- Filling Lid:5-inch twist lid
- Spigot:Built-in brass spigot
Our verdict“This tank is best suited for large-scale, long-term water storage where space and weight are manageable concerns.”
Reliance Products Aqua Tainer 7 Gallon Drinking Water Storage Container Tank (4 Pack)
This 4-pack of 7-gallon containers offers a practical balance between size and portability, making it ideal for outdoor use or smaller emergency supplies. Its rectangular shape with molded contour grips maximizes space efficiency, especially when combined with other storage options like the 5-gallon containers. The inclusion of a screw-on vent and hideaway spigot enhances ease of use, especially during outdoor activities or quick dispensing. Compared to the larger 55-gallon tank, these containers are easier to handle and move but provide significantly less capacity. The plastic material’s durability can degrade over time if not properly maintained, unlike the more robust material of the 55-gallon tank. This set suits outdoor enthusiasts, campers, or small households needing reliable, portable water storage that can be easily stacked or stored in limited spaces.
Pros:- Durable and suitable for outdoor or emergency use
- Space-efficient rectangular design
- Includes a spigot for easy dispensing
Cons:- Bulkier when filled, which may limit storage options
- Plastic may degrade over time without proper maintenance
Best for: Outdoor adventurers, campers, or small households needing durable, portable water containers for short- to medium-term emergency use
Not ideal for: Large families or those seeking long-term, high-volume water storage solutions due to limited capacity
- Capacity:7 gallons per container
- Quantity:4 pack
- Design:Rectangular with molded contour grip
- Features:Screw-on vent, hideaway spigot
- Warranty:5 years
- Material:Durable plastic
Our verdict“This set offers a versatile, portable water storage solution ideal for outdoor or short-term needs, but less suitable for long-term or large-scale storage.”
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 practical, lightweight option for those who need manageable water storage options for camping or small-scale emergencies. Their stackable design helps optimize limited space, and the inclusion of handles and twist ports makes handling and pouring straightforward. Compared to the 7-gallon Reliance containers, these are easier to carry and more flexible for travel or quick deployment. However, their modest capacity means multiple sets are necessary for substantial reserves, and their weight—around 40 pounds when full—may be a challenge for some users. The dimensions are not specified, which could limit placement options in tight storage areas. These containers suit outdoor enthusiasts and preppers with limited space who prioritize portability over large volume storage.
Pros:- Stackable, space-saving design
- Made from durable, BPA-free plastic
- Handles and twist ports for easy handling
Cons:- Heavy when filled, around 40 lbs
- Limited total capacity of 20 gallons for the entire set
Best for: Campers, outdoor enthusiasts, or small households needing portable, easy-to-handle water containers for short-term emergencies
Not ideal for: Large families or those preparing for long-term, high-volume water needs, due to limited total capacity and weight concerns
- Capacity:5 gallons per container
- Number of containers:4
- Material:BPA-free HDPE plastic
- Weight when filled:about 40 lbs each
- Features:Handles, twist ports
Our verdict“This set provides a portable, easy-to-handle water storage option ideal for outdoor use or small-scale emergencies, but not for extensive long-term reserves.”
How We Picked
These products were evaluated based on several critical factors relevant to emergency water storage. Capacity was a primary consideration, ensuring options suited both short-term and long-term needs. Durability and material safety, especially BPA-free and food-grade plastics, were essential for health and longevity. Usability features such as spigots, portability, and stackability were also assessed, as these impact how easily water can be accessed and stored in different environments. Cost was considered alongside build quality to recommend options that balance value and performance. The ranking reflects a combination of these factors, favoring versatility, safety, and user-friendly features suitable for emergency preparedness.Factors to Consider When Choosing Emergency Water Storage Containers
Choosing the right emergency water storage container involves balancing capacity, durability, safety, and ease of use. Understanding these factors helps prevent common mistakes, such as overestimating storage space or selecting materials that degrade over time. It’s also important to consider your available storage area and how you plan to access water during an emergency. A well-chosen container can save time and effort when it matters most, making your preparedness more reliable and efficient.Capacity and Storage Needs
Assess how much water your household will need during an emergency, considering the duration and number of people. Larger tanks provide long-term storage but require significant space and handling effort, while smaller containers are easier to transport and store but may require frequent refills. Opt for a capacity that aligns with your overall preparedness plan, avoiding both over- and underestimation.
Material Safety and Durability
Prioritize containers made from BPA-free, food-grade plastics to prevent water contamination. Look for sturdy construction that withstands rough handling, UV exposure, and temperature fluctuations. Cheaper options may degrade faster, risking leaks or water quality issues, so investing in higher-quality materials can save money over time.
Design and Usability
Features like built-in spigots, stackability, and collapsibility influence how easily water can be accessed and stored. Spigots simplify pouring, especially during emergencies, while stackable designs optimize limited storage space. Collapsible bladder systems are excellent for maximizing space when not in use, but they may be less durable than rigid tanks for long-term storage.
Long-Term Storage and Maintenance
For extended preparedness, select containers designed for long-term storage, with materials resistant to algae growth and contamination. Regular maintenance, cleaning, and rotation are necessary to keep stored water fresh. Larger tanks often require additional filtration or treatment systems to maintain water safety over time.
Cost and Value
While budget-friendly options are tempting, they often compromise on durability or capacity. Investing in higher-quality, long-lasting containers offers better value over time, especially for those planning for long-term emergencies. Balance your budget with your needs to choose containers that provide reliable performance without unnecessary expenditure.
Frequently Asked Questions
How long can I store water in these containers safely?
Stored water can typically remain safe for up to six months if kept in clean, food-grade containers and stored in a cool, dark place. Regular rotation of stored water, at least every six months, helps maintain freshness and safety. Some containers are designed for longer-term storage, but water should be treated or filtered before use if stored for extended periods.
What is the best way to clean and maintain my emergency water storage containers?
Cleaning involves rinsing containers with soap and water, then sanitizing with a solution of one teaspoon of unscented bleach per quart of water. Rinse thoroughly to remove any residual chemicals. Regular inspections for cracks, leaks, or mold are essential, especially before refilling. Proper maintenance extends the lifespan of containers and ensures safe drinking water during emergencies.
Are collapsible water bladders a good long-term solution?
Collapsible bladders are excellent for maximizing storage space and portability, especially in small or temporary setups. However, they may be less durable over many years compared to rigid containers and can be susceptible to punctures or mold if not stored properly. They’re best suited for short to medium-term use or as supplementary storage in emergency plans.
Can I store other liquids in these containers besides water?
While many containers are labeled as food-grade, they are primarily designed for water. Storing other liquids, especially corrosive or sugary substances, can degrade the material and compromise safety. If you plan to store other liquids, check the manufacturer’s recommendations and consider dedicated containers designed for specific substances.
What features should I look for if I want to set up a long-term water storage system?
For long-term setups, choose containers made from durable, UV-resistant, BPA-free materials with secure lids to prevent contamination. Stackable or modular designs help optimize space, while features like spigots facilitate easy access. Regular maintenance, water treatment options, and the ability to rotate stored water are also important considerations to ensure safety and reliability over time.
Conclusion
For most households starting their emergency preparedness journey, the Reliance Products Aqua-Tainer 7 Gallon offers an excellent balance of portability, capacity, and ease of use. Those with space and planning for long-term storage may find the 55 Gallon Tank more suitable, despite its larger footprint. Budget-conscious buyers should consider smaller, BPA-free options like the 5-Gallon Dispenser for flexibility, while advanced preppers might prioritize high-capacity, stackable systems. Beginners should prioritize simple, reliable containers, whereas seasoned planners can invest in modular, long-term solutions to cover all scenarios.
