Choosing the Right Long-Term Water Storage Containers
Storing water for emergencies is a smart move. When the unexpected happens, having safe drinking water is crucial. This guide helps you pick the best containers to keep your water fresh for years.
Key Features to Look For
Good water storage containers have specific features that keep your water safe and make storage easy. Always check for these important points before you buy.
1. Durability and Strength
- Crack Resistance: Containers must be strong. They should not crack if bumped or dropped, especially when full of heavy water.
- Stackability: Look for containers that stack well. This saves valuable space in your closet or basement.
2. Light and UV Protection
- Opaque Color: The best containers are dark blue, black, or opaque (not see-through). Sunlight causes algae and bacteria to grow. Dark colors block the light effectively.
- BPA-Free: Ensure the plastic is certified “BPA-free.” BPA is a chemical that can leak into your water over time.
3. Ease of Use
- Wide Mouth Opening: A large opening makes cleaning the inside easy. You must clean containers regularly to keep water safe.
- Secure Lids: Lids must seal tightly. A good seal keeps contaminants out and prevents slow leaks.
Important Materials for Water Storage
The material your container is made from heavily affects how long the water stays good and how safe it is.
High-Quality Plastics (Food-Grade)
- HDPE (High-Density Polyethylene): This is the gold standard. HDPE plastic is very tough, resists punctures, and blocks light well. Most reliable water bricks and barrels use HDPE.
- Polypropylene (PP): This is another good, sturdy option often used for smaller containers.
Stainless Steel
- Stainless steel is extremely durable and does not leach chemicals. It is often more expensive but lasts virtually forever. Ensure it is food-grade stainless steel (like 304 grade).
Factors That Improve or Reduce Quality
What makes a container great or terrible often comes down to small details.
Improving Water Quality Over Time
- Thick Walls: Thicker plastic walls offer better protection against temperature changes and physical damage.
- Ventilation (When Storing Empty): If the container is empty and stored for a very long time, it should be stored with the lid slightly loose. This allows trapped air to escape and prevents the container from warping.
Reducing Water Quality Over Time
- Thin Plastic: Cheap, thin plastic degrades faster. It often lets more light and air through, spoiling the water sooner.
- Improper Cleaning: If the container is not thoroughly cleaned and sanitized before filling, bacteria will grow, regardless of the container quality.
- Exposure to Heat: Storing containers near a furnace or in direct summer sun rapidly reduces water safety and can warp plastic.
User Experience and Use Cases
Think about how you plan to use the water. This dictates the best shape and size for you.
For Home Shelves (Bulk Storage)
Many people use large 55-gallon blue barrels for storing water in a basement or garage. These hold a lot of water but are hard to move once filled. They are best for long-term, stationary storage.
For Go-Bags and Portability
Water bricks or smaller 5-to-7-gallon containers are excellent if you need to move your supply, like taking it to a vacation cabin or keeping it ready in a vehicle. They fit better on shelves or under beds.
Always remember to rotate your water supply every one to five years, even if the container is high quality. Check the water for any strange smells or cloudiness before use.
10 Frequently Asked Questions (FAQ) About Long-Term Water Storage
Q: How long can I safely store water in these containers?
A: If you use food-grade containers and treat the water properly (using unscented bleach or purification tablets), water can last five years or more. Always check local guidelines.
Q: Should I treat the water before putting it in the container?
A: Yes. Always fill the container with water that has been treated with a small, measured amount of household bleach (check online guides for exact ratios) to kill bacteria.
Q: What is the best place to store my water containers?
A: Store containers in a cool, dark place. Basements or closets away from direct sunlight and heat sources are ideal. Keep them off concrete floors if possible, using wood pallets.
Q: Why must the containers be opaque (not clear)?
A: Clear containers let light in. Light encourages algae and bacteria growth, which makes the water unsafe to drink over long periods.
Q: Is plastic or metal better for long-term storage?
A: Both are good if they are food-grade. Plastic (HDPE) is lighter and cheaper. Metal (stainless steel) is more durable but costs much more.
Q: What does “BPA-free” mean?
A: BPA is a chemical sometimes found in plastics. “BPA-free” means the plastic will not leak this potentially harmful chemical into your drinking water.
Q: How do I clean a large water barrel?
A: You must scrub the inside with a mild soap and rinse thoroughly. Then, sanitize it with a bleach solution before refilling it with fresh water.
Q: Can I store water outside?
A: No. Storing water outside exposes it to extreme temperatures and direct sunlight, which damages the plastic and spoils the water quickly.
Q: What is the standard size for emergency water containers?
A: The common sizes are 5, 7, 10, 30, and 55 gallons. Most experts recommend at least one gallon per person per day.
Q: How heavy is a full 55-gallon barrel?
A: Water weighs about 8.3 pounds per gallon. A 55-gallon barrel weighs roughly 450 pounds when full. You need a strong dolly or moving equipment to handle it.
