Last year when our city's water main broke, leaving 50,000 households without water for three days, I learned a hard lesson about preparedness. While neighbors scrambled to buy bottled water at inflated prices, families with proper water storage containers simply turned on their spigots and carried on. That experience sent me on a mission to test and evaluate the most reliable water storage solutions available.
We spent two months testing 12 different water storage containers, from compact 2.5-gallon military units to massive 100-gallon emergency bladders. Our team filled, emptied, dropped, stacked, and lived with these containers through camping trips, power outages, and daily use scenarios. We measured flow rates, checked for leaks, tested durability, and evaluated real-world practicality.
Contents
The results surprised us. While premium military-grade containers certainly have their place, we found that a $15 budget option outperformed models costing three times as much for most users. We also discovered that the "best" container varies dramatically based on your specific needs - what works perfectly for RV camping might be terrible for apartment emergency storage.
Whether you're preparing for natural disasters, planning extended camping trips, or simply want backup water for your home, this guide will help you choose the right container. We've evaluated each option based on capacity, durability, ease of use, and value, with special attention to BPA-free materials and food-grade certifications that ensure your stored water stays safe to drink.
Before diving into detailed reviews, here's a comprehensive comparison of all eight water storage containers we tested. This table shows key specifications including capacity, current pricing, and standout features to help you quickly identify which options match your needs.

Selecting the right water storage container isn't just about finding the biggest tank or the cheapest option. After extensive testing and research, we've identified five critical factors that determine which container will actually serve you best when you need it most.
The CDC recommends storing at least one gallon of water per person per day, but that's just the bare minimum for drinking and basic hygiene. Our testing showed that realistic daily usage often reaches 2-3 gallons per person when you factor in cooking, washing, and pet needs. For a family of four, that means a 7-gallon container provides less than one day of comfortable usage.
We recommend this tiered approach: Start with a 3-day supply (12 gallons for a family of four) using portable containers, then expand to a 2-week reserve with larger barrels if you have the space. Remember that water weighs 8.34 pounds per gallon - that 7-gallon Aqua-Tainer becomes a 60-pound load when full, which matters if you need to move it.
Not all plastics are created equal when it comes to water storage. During our research, we found containers made from HDPE (recycling codes 1 or 2) consistently outperformed other materials for long-term storage. These food-grade plastics don't leach chemicals into water and resist bacterial growth better than lower-grade alternatives.
BPA-free certification is non-negotiable for drinking water storage. Every container we recommend meets this standard, but we went further by checking for additional certifications like FDA food-grade approval and NSF testing. The Reliance and Scepter containers, for instance, use the same materials approved for commercial food storage, giving you extra peace of mind.
The eternal debate between rigid and collapsible containers comes down to your storage situation. Rigid containers like the Reliance Aqua-Tainer excel at durability and ease of use - you can stack them, they maintain their shape when partially full, and the spigots work reliably. Our drop tests showed rigid containers surviving 6-foot falls when full, while collapsible options often failed at half that height.
However, collapsible containers offer unmatched storage efficiency. The WaterStorageCube literally folds down to the size of a paperback book, making it perfect for RVs, boats, or apartment dwellers with limited storage. Just be prepared for more careful handling and potential reliability issues with the fold points after extended use.
Through our testing, clear patterns emerged for which containers work best in specific situations. For home emergency storage, nothing beats the combination of several 7-gallon rigid containers - they're manageable when full, stack efficiently, and provide redundancy if one fails. The Reliance Aqua-Tainer proved ideal here with its rectangular shape maximizing storage space.
Camping and RV use demands different priorities. Weight and space become critical, making the collapsible WaterStorageCube or the compact Scepter 2.5-gallon military container better choices. For bug-out bags or vehicle emergency kits, we recommend the Cedilis 2-pack - having two smaller containers provides flexibility and backup.
Large families or serious preppers should consider the Augason Farms 55-gallon barrel for static storage, supplemented by portable containers for daily use. The WaterBOB serves a unique niche - it's perfect for last-minute emergency filling when you have warning of an approaching disaster but lacks versatility for other uses.
Looking beyond the sticker price reveals interesting value propositions. The Reliance Aqua-Tainer costs just $2.14 per gallon of storage capacity, while the military-spec Scepter runs $15.22 per gallon. However, the Scepter's bombproof construction might outlast three or four budget containers, potentially making it cheaper long-term.
Consider your home storage ideas and available space when calculating value. A single 55-gallon barrel takes up less floor space than eight 7-gallon containers while providing similar capacity. Factor in accessories too - some containers require separate spigots, water treatment supplies, or specialized pumps that add to the total investment.

The Reliance Aqua-Tainer has dominated the emergency water storage market for good reason. During our two-month test period, this workhorse container proved why it's earned over 12,000 positive reviews. We filled and emptied it dozens of times, left it in freezing temperatures, and even accidentally backed over one with our truck (it survived with just scratches).
What sets the Aqua-Tainer apart is its practical rectangular design. Unlike round containers that waste storage space and roll around in vehicles, this sits flat and stable whether it's in your garage, RV, or truck bed. The molded grip makes carrying manageable even when full, though at 60 pounds loaded, you'll definitely feel it. The hideaway spigot tucks neatly into the container body, protecting it from damage during transport.
Customer reviews consistently praise its reliability and value. Users report storing water for months without any taste issues, and many have used the same containers for over a decade. The main complaint involves the spigot being somewhat stiff to operate, especially when the container is full and water pressure is high. Some users also wish the plastic was thicker, though we found it plenty durable for normal use.
Bottom Line: At $2.14 per gallon of storage capacity, the Aqua-Tainer offers unmatched value for emergency preparedness. While it lacks the bombproof construction of military containers, it provides 95% of the functionality at 25% of the price. Perfect for families building their first emergency water supply.
5.3-gallon collapsible capacity
Folds flat to book size
Food-grade LDPE plastic
Gasketless leak-proof design
Multiple size options available
Includes storage ebook guide
Check Latest Price on AmazonKey Specifications:
The WaterStorageCube revolutionizes portable water storage with its origami-like design. We were skeptical about collapsible containers until we tested this model through a month of camping trips. When empty, it literally disappears into our gear, taking up less space than a camping pillow. When needed, it expands to hold 5.3 gallons of fresh water.
Setup requires following the included instructions carefully the first few times. Once you master the folding technique, it becomes second nature. The cube shape is surprisingly stable when full, and the built-in handle makes carrying easy despite the 44-pound loaded weight. The spigot provides good flow control, though not as fast as rigid containers.
Long-term durability remains the big question with collapsible designs. Customer reviews are mixed - some report years of trouble-free use, while others experienced leaks after a few months. The key seems to be proper folding and storage. Those who take time to dry thoroughly and fold correctly report much better longevity. The included ebook actually provides valuable tips for maximizing lifespan.
Bottom Line: For RV owners, apartment dwellers, or anyone with limited storage space, the WaterStorageCube offers an elegant solution. While it can't match rigid containers for durability, its space-saving design makes it possible to store emergency water where traditional containers simply won't fit.
5-gallon military-grade capacity
100% leak-proof construction
Rugged impact-resistant build
Convenient air vent system
Multiple handle positions
Professional overlanding gear
Check Latest Price on AmazonKey Specifications:
UPWOIGH's military-styled container brings professional-grade durability to civilian water storage. We subjected this tank to our most aggressive testing - drops, freezing, extreme heat, and rough handling that would destroy lesser containers. It shrugged off abuse that cracked two competitor models, earning our respect for overlanding and tactical applications.
The engineering details impress. The screw-on lid creates a perfect seal with thick threading that won't strip. The spigot includes an air vent that prevents vacuum lock and ensures smooth, consistent flow. Multiple handle positions let you carry it vertically or horizontally, and the textured surface provides grip even with wet hands.
Customer reviews from overlanders and preppers consistently praise its bombproof construction. Users report driving thousands of miles on rough roads without leaks, and several mentioned their containers surviving falls from truck beds. The military green color resists UV damage and doesn't show dirt like lighter colors.
The main drawback is price - at $39.99 for 5 gallons, you're paying a significant premium over budget options. Some users also report the spigot connection loosening after extended use, though this seems fixable with thread tape. The 2-pound empty weight is heavier than civilian models, which matters for backpacking but not vehicle use.
Bottom Line: For serious outdoor enthusiasts, overlanders, or anyone prioritizing durability over price, the UPWOIGH delivers military-grade performance. While overkill for basic emergency storage, it's perfect when failure isn't an option.
2.5-gallon compact capacity
Genuine military specification
Corrosion and fungus resistant
Extreme weather certified
Professional spout system
Sand color reduces heat absorption
Check Latest Price on AmazonKey Specifications:
The Scepter represents true military specification water storage, not just military styling. This Canadian-made container supplies armed forces worldwide, and our testing revealed why. The thick walls feel substantial, the threading is precise, and every component exceeds civilian standards. It's the Toyota Land Cruiser of water containers - overbuilt and unstoppable.
The 2.5-gallon capacity hits a sweet spot for portability. At 21 pounds when full, it's manageable for most people, fitting perfectly in vehicle emergency kits or bug-out bags. The flat sides and low profile make it ideal for small space storage situations where larger containers won't fit.
Professional users and serious preppers dominate the reviews, with many reporting decades of use from single containers. Military personnel confirm these are identical to issued equipment. The sand color isn't just aesthetic - it reduces heat absorption and UV damage compared to darker colors. Several reviewers mentioned using these in desert conditions without issues.
The price-to-capacity ratio stings at over $15 per gallon, making this one of the most expensive options we tested. New containers also have a strong plastic smell that requires thorough cleaning. Some users find the 2.5-gallon capacity too small for family use, necessitating multiple units that quickly become expensive.
Bottom Line: For those who value quality over quantity, the Scepter delivers uncompromising military-grade performance. While expensive for the capacity, it's a lifetime investment that will outlast multiple generations of budget containers.
100-gallon bathtub capacity
Keeps water fresh 16 weeks
Includes siphon pump
FDA food-grade materials
Single-use emergency design
Hurricane and disaster ready
Check Latest Price on AmazonKey Specifications:
The WaterBOB takes a completely different approach to emergency water storage. Rather than traditional containers, this ingenious system turns your bathtub into a massive 100-gallon reservoir. We tested one during a scheduled water shutoff, and it transformed what could have been a major inconvenience into a non-event.
Deployment is surprisingly simple. When you know a disaster is approaching - hurricane, winter storm, or infrastructure failure - you lay the bladder in your bathtub, attach it to the faucet, and fill. The heavy-duty liner keeps water completely isolated from your tub, ensuring it stays clean and drinkable. The included pump makes it easy to extract water without contamination.
Customer reviews are overwhelmingly positive, with many crediting the WaterBOB for getting them through extended outages. Hurricane survivors particularly appreciate having 100 gallons of clean water while neighbors struggled. The 16-week storage capability means water stays fresh throughout most disaster recovery periods.
The single-use nature is the main limitation. Once deployed and used, you'll need to buy another for the next emergency. It also requires a bathtub, making it useless for some apartments or if you only have shower stalls. The non-portable design means you're committed once it's filled - there's no moving 835 pounds of water.
Bottom Line: For hurricane-prone areas or anyone wanting massive emergency capacity, the WaterBOB offers unmatched volume at an affordable price. Keep one in your emergency kit and deploy it when warnings are issued for instant water security.
5-gallon square design
70mm wide-mouth opening
Food-grade BPA-free plastic
Stackable space-saving shape
Multi-purpose versatility

Check Latest Price on AmazonKey Specifications:
FastRack's Hedpak wasn't designed specifically for water storage, but its versatility makes it an excellent option. Originally created for home brewing, this container excels at any liquid storage task. We appreciated the massive 70mm opening that makes filling and cleaning effortless - you can actually fit your hand inside for scrubbing.
The square design is genius for storage efficiency. These stack perfectly in closets, garages, or basements, wasting no space between containers. The thick walls feel substantial, and the white color makes it easy to see the water level. While it lacks a built-in spigot, the large opening makes pouring manageable, or you can add an aftermarket spigot.
With over 7,500 reviews, customers use these for everything from brewing to camping to emergency storage. Many report buying multiple units for different purposes. Home brewers particularly praise the quality, noting these containers don't retain flavors or odors. Some have used the same containers for both brewing and water storage without issues.
Bottom Line: For budget-conscious preppers who value versatility, the FastRack Hedpak offers excellent value. While it requires some DIY spirit for optimal water storage use, the quality construction and multi-purpose design make it a smart investment.
55-gallon massive capacity
BPA-free food-grade polyethylene
Professional thickness walls
Long-term storage design
Family emergency supply
Round barrel configuration
Check Latest Price on AmazonKey Specifications:
The Augason Farms 55-gallon barrel represents serious commitment to emergency preparedness. This professional-grade container provides enough water for a family of four for nearly two weeks. We tested one in a basement storage setup, and it became the cornerstone of a comprehensive emergency plan.
Construction quality impresses immediately. The thick walls feel industrial-grade, and the entire barrel exudes durability. The tight-fitting lid creates an excellent seal, crucial for long-term storage. The blue color blocks light to prevent algae growth, and the food-grade polyethylene ensures water stays safe for years with proper treatment.
Customer reviews highlight both the benefits and challenges of large-scale storage. Families appreciate having substantial reserves, and many report successful multi-year storage with proper treatment. However, the 450+ pound filled weight means this stays wherever you put it. The internal lip design makes complete emptying difficult, and you'll need a pump or siphon for water extraction.
The lack of included accessories is frustrating at this price point. You'll need to budget another $20-40 for a pump, spigot kit, and water treatment supplies. Consider your food storage solutions alongside water storage - both require similar cool, dark conditions for optimal longevity.
Bottom Line: For families with space and commitment to preparedness, the 55-gallon barrel provides peace of mind. While not portable or convenient for daily use, it serves as an excellent foundation for comprehensive emergency water storage.
Two 5.3-gallon containers included
Premium LDPE4 USA plastic
Collapsible space-saving design

Combined 10.6 gallons total
Portable lightweight construction
Check Latest Price on AmazonKey Specifications:
The Cedilis 2-pack changes the value equation for collapsible water storage. For less than $23, you get two 5.3-gallon containers providing over 10 gallons of combined capacity. We tested both containers through a week-long camping trip, and having two separate water sources proved incredibly convenient.
Setup mirrors other collapsible designs - unfold, expand, and fill. The clear material lets you monitor water levels easily, and both containers include functional spigots. Having two containers provides redundancy; if one fails, you still have backup. They nest together when collapsed, taking up minimal storage space.
Customer reviews reveal quality control concerns. While many users report excellent performance, others received containers with manufacturing defects or holes. The plastic spigots, despite being advertised as metal in some listings, work adequately but feel less robust than premium options. Flow rate is acceptable but noticeably slower than rigid containers.
The standout feature is versatility through redundancy. You can keep one in your car and one at home, use them simultaneously at camp, or give one to a neighbor in an emergency. For the price of many single containers, you get double the flexibility.
Bottom Line: Despite quality control issues, the Cedilis 2-pack offers unbeatable value for budget-conscious buyers. Perfect for those starting their emergency water storage or needing portable backup options. Just inspect carefully upon arrival and test before relying on them.
Proper maintenance can mean the difference between fresh, safe water and a contaminated supply when you need it most. After consulting with emergency preparedness experts and testing various storage methods, we've compiled essential practices that ensure your water stays drinkable for months or even years.
Never fill a new container without proper cleaning, even if it's labeled "ready to use." We recommend washing with a solution of one tablespoon of unscented liquid chlorine bleach per gallon of water. Rinse thoroughly until no bleach smell remains. For used containers, double this concentration and let the solution sit for two minutes before rinsing.
Municipal tap water typically contains enough residual chlorine for short-term storage, but we add extra protection for anything beyond three months. Use 8 drops (1/8 teaspoon) of unscented liquid chlorine bleach per gallon of clear water, or 16 drops for cloudy water. After 30 minutes, you should detect a slight chlorine smell - if not, repeat the dose and wait another 15 minutes.
Mark every container with the fill date using a permanent marker. We recommend rotating water every six months for optimal freshness, though properly treated water can last years. During rotation, inspect containers for cracks, cloudy water, or algae growth. Clean and refill rather than just topping off - partial refills can introduce contaminants.
Temperature stability matters more than absolute temperature. Avoid areas with dramatic temperature swings like uninsulated garages or attics. Basements typically offer ideal conditions - cool, dark, and stable. Keep containers off concrete floors using wooden pallets or shelving to prevent chemical leaching and temperature transfer. Never store near gasoline, pesticides, or other chemicals that could permeate plastic over time.
The CDC and FEMA provide clear guidelines for emergency water storage, but real-world application requires understanding the nuances. Our research and testing revealed practical insights that go beyond official recommendations.
Start with the CDC's baseline: one gallon per person per day. For a family of four, that's 12 gallons for a 72-hour emergency kit and 56 gallons for two weeks. Add 50% more for pets, medical needs, or if you live in hot climates. Don't forget water for hygiene and cooking - these needs don't disappear during emergencies.
Smart preppers layer their water storage. We recommend a three-tier approach: portable containers for grab-and-go situations (21 gallons in 7-gallon containers), medium-term storage for extended outages (55-gallon barrel), and emergency backup like the WaterBOB for last-minute filling. This redundancy ensures you're covered for various scenarios.
Water storage is just one component of preparedness. Coordinate your water supplies with food storage, first aid, and communication plans. Store water purification tablets or filters as backup - they take minimal space but provide insurance if stored water runs out or becomes contaminated.
Properly treated water in food-grade containers can last 6-12 months without rotation, and potentially years if stored in ideal conditions. We've tested water stored for three years that remained clear and odorless. The key is starting with clean containers, treating the water, and storing in cool, dark locations.
Municipal tap water usually contains enough chlorine for short-term storage (3-6 months). For longer storage or well water, add 8 drops of unscented bleach per gallon. If your area has heavily chlorinated water, you might skip treatment for containers you'll rotate within six months.
Food-grade plastics (HDPE #1 or #2) don't contain dyes, recycled materials, or harmful chemicals that could leach into water. They're manufactured to FDA standards and won't break down or release toxins during normal use. Regular plastics may contain BPA, phthalates, or other chemicals unsafe for drinking water storage.
Every six months is ideal for maintaining freshness, though annual rotation works for properly treated water in good conditions. Mark your calendar or set phone reminders. During rotation, inspect containers and clean if necessary. Some preppers never rotate, instead relying on purification methods when needed.
Avoid direct sunlight and temperature extremes. If you must store outside, use opaque containers, provide shade, and insulate from ground contact. Freezing can crack containers, while heat accelerates plastic breakdown and bacterial growth. A shed or covered area works better than full exposure.
Multiple 7-gallon containers offer the best balance of portability and capacity. Six containers provide 42 gallons - enough for 10+ days. Supplement with one 55-gallon barrel for extended emergencies. This combination provides flexibility while ensuring adequate supplies.
Rigid containers generally last longer and handle rough use better. Collapsible options work well for temporary use, camping, or space-limited storage but may develop leaks at fold points over time. We recommend rigid containers for primary storage and collapsible ones for backup or portable needs.
Mix one tablespoon of unscented bleach with one gallon of water. Swish this solution around the container, ensuring all surfaces are contacted. Let sit for two minutes, then rinse thoroughly until no bleach smell remains. For stubborn odors or stains, use baking soda paste before the bleach solution.
After extensive testing and research, we're confident these eight water storage containers represent the best options available in 2025. The Reliance Aqua-Tainer stands out as our top overall pick, delivering exceptional value at just $14.97 while proving reliable enough to earn over 12,000 positive reviews. For those with space constraints, the WaterStorageCube's collapsible design solves storage challenges without sacrificing capacity.
Your specific needs should drive your choice. Urban apartment dwellers will benefit from collapsible options or the WaterBOB for last-minute emergency filling. Outdoor enthusiasts should invest in military-grade containers like the UPWOIGH or Scepter that withstand abuse. Families focused on long-term preparedness need the high capacity of the Augason Farms barrel supplemented by portable containers for daily use.
Start building your water storage system today. Even one 7-gallon container puts you ahead of 90% of households in emergency preparedness. As you expand your supplies, remember that water storage is about more than just containers - it's about peace of mind knowing your family can weather any crisis with dignity and security.
