Rockwell Exodus 35 Gallon Stackable Emergency Water Storage Tank, BPA-Free, Made in USA
The Rockwell Exodus 35 Gallon Tank excels in safety, with BPA-free materials and NSF/ANSI/FDA compliance, making it ideal for storing drinking water. Its impact-resistant walls are thicker than many competitors, offering added durability. While its 35-gallon capacity is less than larger models, this makes it more manageable and easier to move — especially with the included hardware for filling and dispensing. Compared to the 55-gallon options, this tank is perfect for campers who prioritize water safety and need a more portable solution. However, its smaller size means you’ll need multiple units for larger water needs, and it can be heavy when filled, which might require assistance. Overall, this model fits best with those who want a high-quality, safe water container for short-term or moderate use.

Our verdict“A top choice for safe, impact-resistant drinking water storage in a manageable size for camping or emergency use.”
55 Gallon Stackable Emergency Water Storage Tank – Food Grade BPA-Free Water Container for Long-Term Home Preparedness
This 55-gallon tank is designed with long-term survival in mind, made from food-grade, BPA-free rotationally molded polyethylene. Its stackable design makes it suitable for stacking in a stable outdoor or indoor setting, and it includes a built-in brass spigot for easy dispensing. While its large capacity makes it excellent for family preparedness, its weight when filled can be a challenge for movement, and it doesn’t come with water or accessories — so it’s primarily a storage solution rather than a ready-to-use unit. Compared to the other options, this tank emphasizes safety and durability for extended storage, but it’s less portable and better suited for stable environments within a camping setup. This makes it ideal for off-grid living or long-term emergency supplies rather than frequent campsite refilling.
Pros:- Large capacity suitable for family preparedness
- Made from food-grade BPA-free polyethylene
- Stackable for space efficiency
Cons:- Heavy when filled, difficult to move
- No included water or accessories
Best for: Campers and preppers focused on long-term, safe water storage for emergencies

Factors to Consider When Choosing Best Large Water Storage System For Camping
Choosing the right large water storage system for camping depends on your specific needs, including capacity, portability, safety, and intended use. The key is to balance these factors to find a tank that offers enough water for your trip, fits your space constraints, and withstands outdoor conditions. In this guide, I’ll walk through the main considerations—capacity, material, safety features, portability, and stacking ability—that will help you select the best option for your camping adventures.
Capacity and Size
Capacity is the most obvious factor—how much water do you need? Larger tanks like 55 gallons provide ample supply for extended trips, but they also take up more space and are heavier when full. If you’re camping in a spot with limited space or need to move the tank frequently, a smaller capacity like 35 gallons might be more practical. Consider your water needs, storage space, and whether you’ll need to transport the tank often.
Material and Durability
The material impacts how well your tank withstands outdoor conditions. UV-proof high-density polyethylene (HDPE) is common and offers good resistance to sunlight and impacts. Food-grade BPA-free plastics are essential if you plan to store drinking water for long periods. Thicker walls and impact-resistant designs add durability, especially for off-grid or long-term storage scenarios.
Safety and Food-Grade Certification
For drinking water, safety certifications like NSF/ANSI/FDA compliance are critical. BPA-free materials prevent leaching of harmful chemicals, making the tank safe for potable water. If your goal is to store drinking water, prioritize tanks with these certifications and BPA-free construction to protect your health during camping or emergencies.
Portability and Stackability
Most large tanks are stackable, which saves space, but their weight can make moving them challenging. Consider tanks with handles, sturdy construction, or hardware that facilitates filling and dispensing. If frequent movement is required, models with lighter materials or smaller capacity may be better, even if you need more units to reach your desired total capacity.
Additional Features and Accessories
Look for features like integrated spigots, drain plugs, and easy-to-use lids. Some tanks come with hardware for filling and dispensing, which can save setup time. Additionally, durability features like UV resistance and impact strength extend the lifespan of your tank, especially if it will be exposed to outdoor elements for long periods.
Frequently Asked Questions
How much water capacity do I need for camping?
The amount of water you need depends on the number of people, duration of your trip, and planned activities. For a solo camper on a weekend, 10-20 gallons may suffice, but for a family or longer trip, 35-55 gallons offers more comfort and flexibility. Larger tanks reduce refill frequency but require more space and effort to move or store.
What material is best for outdoor water storage tanks?
High-density polyethylene (HDPE) is the most common and reliable choice, providing UV resistance and impact durability. For drinking water, BPA-free HDPE ensures safety and prevents chemical leaching. Food-grade, BPA-free options are especially important if you plan to store potable water long-term.
Are stackable water tanks safe for long-term storage?
Yes, provided they are made from food-grade or BPA-free materials and are designed for long-term storage. Properly sealed and stored tanks resist contamination and UV damage, making them suitable for extended use. However, weight and space considerations are important, especially when stacking multiple units.
Can I use a large water tank for both drinking and non-potable water?
While some tanks are designed for potable water, using the same tank for non-potable water can lead to contamination if not cleaned properly. It’s best to use a dedicated, food-grade tank for drinking water and reserve other tanks for gray or non-potable water to prevent cross-contamination.
How do I maintain and clean my water storage tank?
Regular cleaning with mild soap and water, followed by thorough rinsing, is recommended to prevent algae and bacterial growth. For long-term storage, sanitizing the tank with a diluted bleach solution periodically helps maintain water quality. Always ensure the tank is dry and stored in a cool, shaded area when not in use.
Conclusion
For campers needing large capacity and durability, the WaterPrepared 55 Gallon Tank offers reliable, space-efficient storage. Those focused on safe drinking water should consider the Rockwell Exodus 35 Gallon Tank for its BPA-free, impact-resistant design. If long-term preparedness or multi-use storage is your priority, the 55-Gallon Food Grade Tank provides a safe, durable solution, though it’s less portable. Matching your choice to your camping style and water needs ensures a well-prepared outdoor experience.
