Recommendations for an Emergency Home Water Supply
- Thoroughly wash your water container. If the container has been used, make sure it formerly contained only something that was safe for human consumption.
- Disinfect the container by filling it with a solution of tap water and a few drops of bleach. Let it stand for 20 minutes.
- Empty the container and rinse well with tap water.
- Fill the container with tap water and store in a cool, dark place.
- While this water can be safe indefinitely, it is good to change it yearly.
Methods for Disinfecting Tap Water when there's a Boil Water Notice
After an emergency "Boil Water Order," do one of the following:
- Bring water to a rolling boil and boil for 3 to 5 minutes.
- Add 16 drops of bleach per gallon of water and let stand for 30 minutes before using. If water does not have a slight bleach odor, repeat the treatment and let stand for another 15 minutes.
Note: Use only regular bleach with 5.25 percent sodium hypochlorite. Do not use scented or color-safe bleach.
- Purchase disinfectant tablets at a sporting goods store. Use 1 tablet to disinfect one quart of water or 2 tablets for cloudy water.
