Water is the most essential resource for survival. Whether you’re preparing for emergencies, natural disasters, or just want a reliable backup, knowing how to store water properly can be a lifesaver. Improper storage can lead to contamination, bacteria growth, and even water shortages when you need it the most.
In this guide, we’ll break down the best ways to store water safely, ensuring it remains clean, drinkable, and ready for use whenever you need it.
Why Proper Water Storage Matters
Water can become unsafe due to bacterial growth, chemical contamination, and improper storage conditions. Poorly stored water can harbor pathogens that cause diseases like cholera, dysentery, and E. coli infections. By following proper storage methods, you ensure access to safe drinking water in any situation.
How Much Water Should You Store?
The CDC and FEMA recommend storing at least one gallon of water per person per day for a minimum of two weeks. If you live in a hot climate or have high water needs, you should store more.
Breakdown of Water Needs
| Household Members | Minimum Water Needed (14 Days) |
|---|---|
| 1 Person | 14 Gallons |
| 2 People | 28 Gallons |
| 4 People | 56 Gallons |
| 6 People | 84 Gallons |
This includes drinking, cooking, and minimal hygiene needs. If you plan to use stored water for cleaning and sanitation, consider storing double this amount.
Best Containers for Water Storage
Not all containers are safe for long-term water storage. The wrong type of container can leach harmful chemicals into the water or allow bacteria to grow. Here are the best options:
1. FDA-Approved Food-Grade Plastic Containers
- Look for BPA-free, high-density polyethylene (HDPE) containers.
- Choose containers specifically labeled as safe for water storage.
- Avoid reusing old milk jugs, as they degrade over time and are difficult to clean properly.
2. Glass Containers
- Must be sterilized before use.
- Ensure they have airtight lids.
- Store away from light to prevent algae growth.
3. Stainless Steel Water Containers
- Highly durable and resistant to chemical contamination.
- Do not store chlorinated water in stainless steel, as it may cause corrosion.
4. Large Water Barrels (55-Gallon Drums)
- Ideal for long-term storage.
- Must be food-grade plastic and kept off the ground.
- Use a siphon pump for easy access.
5. Water Bricks and Stackable Containers
- Space-efficient and portable.
- Excellent for emergency kits or bug-out bags.
How to Properly Store Water
1. Choose a Safe Storage Location
- Keep water in a cool, dark place, away from direct sunlight.
- Avoid storing near chemicals, gasoline, or cleaning products, as plastic containers can absorb fumes.
- Store on a raised surface (e.g., wood pallets) to prevent contamination from flooring.
2. Treat Water for Long-Term Storage
Even tap water needs treatment if stored long-term. Use one of the following methods:
Chlorination (Bleach Method)
- Add 8 drops of unscented household bleach per gallon of water.
- Mix well and let sit for 30 minutes before sealing the container.
- Label with the date of treatment.
Boiling (for Small Batches)
- Bring water to a rolling boil for at least 1 minute (or 3 minutes at high altitudes).
- Allow it to cool before storing in sanitized containers.
Water Purification Tablets
- Follow the manufacturer's instructions.
- Commonly used for emergency water storage.
How Long Can You Store Water?
Tap Water (Treated)
- Can last 6 months to 1 year with proper storage.
- Refresh stored water every 6 months for best quality.
Commercially Bottled Water
- Typically has a 2+ year shelf life, but check expiration dates.
- Store in a cool, dark place to maintain quality.
Long-Term Water Storage with Stabilizers
- Water treated with a water preserver can last up to 5 years without needing rotation.
- Best for large water drums and barrels.
Signs Your Stored Water Has Gone Bad
Even properly stored water can become unsafe over time. Check for:
✅ Cloudy or discolored appearance.
✅ A musty or foul odor.
✅ Floating particles or algae growth.
✅ A slimy texture inside the container.
If any of these signs are present, discard the water and disinfect the container before refilling.
Additional Water Storage Tips
✔️ Label all containers with the storage date and treatment method used.
✔️ Rotate water every 6 months unless using long-term water stabilizers.
✔️ Have multiple storage options—a mix of large barrels and portable containers.
✔️ Keep purification methods on hand (bleach, filters, boiling equipment).
✔️ Prepare for extreme weather—store in insulated spaces to prevent freezing.
Final Thoughts
Water is life, and proper storage ensures that you and your family always have access to clean, safe drinking water. Whether you’re prepping for an emergency, a natural disaster, or just want a reliable backup, following these storage guidelines will keep you ready for anything.
