How to Store Water for Long-Term Survival

Water is one of the most essential resources for survival, and it’s important to store enough of it to last during an emergency or long-term survival situation. Properly storing water can ensure you have access to clean, drinkable water when natural disasters, power outages, or other emergencies strike. Here’s how to store water for long-term survival.

1. Determine How Much Water You Need

The first step in storing water is determining how much you need. For a minimum supply, you should plan on storing at least 1 gallon of water per person per day. For a family of four, that’s 4 gallons per day. This amount accounts for drinking, cooking, and basic hygiene. It’s a good idea to store at least a 3-day supply of water, but a 2-week supply is recommended for longer-term preparedness.

2. Choose the Right Containers

Water should be stored in food-grade containers that are durable, airtight, and BPA-free. Some of the best options for water storage containers include:

• Water Storage Barrels: Large, 55-gallon barrels are ideal for bulk water storage. They are sturdy, can store large quantities, and take up minimal space when sealed properly.
• Water Jugs: 1- to 5-gallon water jugs are easy to transport and store in small spaces. They’re also great for household use during emergencies.
• Water Bottles: If you need to store water in smaller quantities, individual water bottles can be used, but ensure they’re stored in a cool, dry place.
• Mylar Bags: Mylar bags with food-grade liners can be used for storing water in bulk. They are lightweight, compact, and can be stored in larger spaces.

3. Use Water Treatment or Purification Tablets

For long-term water storage, it’s recommended to treat the water to prevent contamination and bacterial growth. Use water purification tablets, drops, or chlorine bleach to disinfect water. Follow the manufacturer’s instructions on the proper dosage to ensure the water remains safe for consumption over time. If using chlorine bleach, use 8 drops per gallon of water.

4. Store Water in a Cool, Dark Place

Water should be stored in a cool, dark environment to prevent algae growth and the degradation of water quality. Avoid storing water in direct sunlight or areas with high temperatures, as this can affect its safety and taste. A basement or closet that remains cool and dry is an ideal location.

5. Rotate Your Water Supply

Even though water doesn’t spoil, it’s still a good idea to rotate your supply every 6 months to ensure its freshness and safety. When you rotate your water supply, use the older containers for everyday use, and replace them with freshly treated water. Mark your storage containers with the date so you can track when they were filled.

6. Consider Using Water Filters

In addition to storing water, it’s important to have the means to purify water in case your storage supply runs out or becomes contaminated. Water filters, such as portable filtration systems, activated carbon filters, or UV water purifiers, can help make water from natural sources safe for consumption. Be sure to store these filters in your emergency preparedness kit.

7. Check for Leaks and Contamination

Regularly check your water storage containers for leaks, cracks, or contamination. Over time, plastic containers can degrade, so it’s important to inspect them periodically. If you notice any contamination, dispose of the water safely and replace it with fresh, treated water.

8. Use Water Preservatives

Some people choose to use water preservatives, such as sodium benzoate or potassium sorbate, to extend the shelf life of water stored for long periods. These preservatives can help prevent the growth of bacteria and algae and keep the water fresh for longer. Always follow the recommended usage guidelines when using water preservatives.

9. Be Prepared for Water Shortages

In a long-term survival situation, water may become scarce, and your stored water may be the only supply available. If this happens, you can use alternative methods to source water, such as rainwater collection, filtering water from streams or lakes, or melting snow. Always be sure to purify any water you collect before drinking it.

Final Tips

Storing water for long-term survival requires preparation, knowledge, and the right storage equipment. By following these tips and ensuring you have enough safe water for yourself and your family, you can be ready for emergencies and unforeseen situations. Regularly check your water storage and replenish it as needed to maintain a sustainable water supply.
