Tap water is generally safe to drink for about 6 to 12 months when stored properly in a clean, sealed container. However, various factors such as storage conditions and the presence of contaminants can affect its safety over time. Understanding these factors helps ensure your tap water remains safe for consumption.
What Affects the Safety of Stored Tap Water?
Several factors can influence how long tap water stays safe to drink. By understanding these, you can better store your water and extend its shelf life.
- Storage Container: Use food-grade containers made of glass, stainless steel, or BPA-free plastic to avoid chemical leaching.
- Temperature: Store water in a cool, dark place to prevent bacterial growth and degradation.
- Contaminants: Ensure containers are thoroughly cleaned before use to avoid introducing bacteria or other contaminants.
How to Store Tap Water Safely?
Proper storage is key to maintaining the safety of tap water over time. Follow these steps to ensure your water remains drinkable:
- Clean the Containers: Wash containers with soap and water, then sanitize with a solution of 1 teaspoon of unscented liquid household chlorine bleach per quart of water.
- Fill and Seal: Fill containers with tap water, leaving some space at the top for expansion. Seal tightly to prevent contamination.
- Label and Date: Clearly label each container with the date it was filled to track its age.
- Check Regularly: Inspect containers for leaks or signs of contamination, and replace water every 6 to 12 months.
How to Tell If Stored Tap Water Is No Longer Safe?
Knowing when tap water is no longer safe to drink is important to prevent health risks. Here are some signs that your stored water may be compromised:
- Cloudiness or Sediment: Indicates possible contamination.
- Off Odor: Suggests bacterial growth or chemical contamination.
- Unpleasant Taste: Could indicate leaching of materials from the container or degradation of water quality.
Can Tap Water Be Treated to Extend Its Shelf Life?
Yes, treating tap water can help extend its shelf life. Here are some methods you can use:
- Boiling: Boil water for at least one minute to kill bacteria and viruses.
- Chemical Disinfection: Add 8 drops of unscented liquid household chlorine bleach per gallon of water, mix well, and let it sit for 30 minutes before use.
- Filtration: Use a high-quality water filter to remove contaminants before storage.

How Does Tap Water Compare to Bottled Water for Storage?
| Feature | Tap Water | Bottled Water |
|---|---|---|
| Cost | Low | Higher than tap water |
| Shelf Life | 6-12 months (properly stored) | 1-2 years (sealed) |
| Environmental Impact | Lower (reusable containers) | Higher (single-use plastic) |
| Taste | Varies by source | Consistent (brand-specific) |
What Are the Benefits of Using a Water Filter?
Water filters can improve the taste and safety of tap water by removing impurities such as chlorine, lead, and sediment. They are cost-effective and environmentally friendly compared to bottled water, providing clean water on demand.
How Often Should I Replace Stored Tap Water?
Stored tap water should be replaced every 6 to 12 months to ensure it remains safe to drink. Regularly checking for signs of contamination, such as cloudiness or an off odor, can also help determine when water needs to be replaced.
Is It Safe to Drink Tap Water During a Boil Water Advisory?
During a boil water advisory, it is not safe to drink tap water without boiling it first. Boil water for at least one minute to kill harmful bacteria and pathogens. Alternatively, use bottled water until the advisory is lifted.
How Can I Improve the Taste of Stored Tap Water?
To improve the taste of stored tap water, consider using a charcoal filter or adding a small amount of fresh lemon juice. Ensure containers are clean and free from odors before filling them with water.
Conclusion
Maintaining the safety of stored tap water involves proper storage techniques and regular monitoring for signs of contamination. By using clean containers, storing water in a cool, dark place, and replacing it every 6 to 12 months, you can ensure your tap water remains safe to drink.
