Water storage is essential for emergency preparedness, but how long can you safely store water? Generally, you can store commercially bottled water for about two years if kept in a cool, dark place. However, if you are storing water yourself, it’s best to use food-grade containers and replace the water every six months to ensure safety and freshness.
How Long Can You Store Water Safely?
Water is a critical component of survival, and understanding how to store it properly can make a significant difference during emergencies. Long-term water storage requires careful attention to ensure the water remains safe to drink. Let’s explore the best practices for storing water and how long it can last.
What Are the Best Containers for Storing Water?
Choosing the right container is crucial for maintaining water quality. Here are some options:
- Food-grade plastic bottles or jugs: These are ideal for storing water as they are designed to hold consumable liquids without leaching harmful chemicals.
- Glass bottles: While they are heavy and breakable, glass is a non-reactive material that doesn’t affect water taste or safety.
- Stainless steel containers: These are durable and do not leach chemicals, but they should not be used if you plan to treat the water with chlorine, as it can corrode the steel.
How to Prepare Water for Long-Term Storage?
To ensure your stored water remains safe, follow these steps:
- Clean the containers: Wash them with soap and water, then sanitize with a solution of one teaspoon of unscented liquid household chlorine bleach to a quart of water.
- Fill with water: Use tap water that has been treated with chlorine. If using well water, consider adding a few drops of bleach to disinfect.
- Seal tightly: Ensure lids are secure to prevent contamination.
- Label and date: Mark the containers with the date of storage to track when it needs replacement.
How Often Should You Rotate Stored Water?
For self-stored water, it is generally recommended to rotate your supply every six months. This ensures that you always have fresh, safe water available. Commercially bottled water can last longer, typically up to two years, but it’s wise to check expiration dates and store them properly.
What Are the Signs That Stored Water Has Gone Bad?
Even with careful preparation, stored water can sometimes become unsafe. Look out for:
- Cloudiness or particles: Indicates possible contamination.
- Off smell or taste: Suggests bacterial growth or chemical leaching.
- Damaged containers: Cracks or leaks can lead to contamination.
How to Treat Stored Water Before Drinking?
If you suspect your stored water might not be safe, here are some treatment options:
- Boiling: Bringing water to a rolling boil for at least one minute can kill most pathogens.
- Chemical disinfection: Use water purification tablets or unscented household bleach (8 drops per gallon) to disinfect.
- Filtration: Use a portable water filter designed to remove bacteria and protozoa.

Can I Use Milk Jugs for Water Storage?
Milk jugs are not recommended for long-term water storage because they are biodegradable and can break down over time, leading to leaks and contamination.
Conclusion
Proper water storage is a key component of emergency preparedness. By using the right containers, regularly rotating your supply, and knowing how to treat water before use, you can ensure that your stored water remains safe and reliable. Always plan for at least a two-week supply per person, and remember to check your storage conditions regularly.
