During flood, drinking water should be:

Boiled:
- Boiling water is the most effective way to kill harmful bacteria, viruses, and parasites that may be present in floodwater.
- It is recommended to bring the water to a rolling boil for at least one minute to ensure it is safe to drink.

Filtered:
- Filtering water can help remove any sediment, debris, or contaminants that may be present in floodwater.
- Using a water filter designed to remove bacteria, parasites, and other impurities can make the water safer to drink.

Sedimented:
- Allowing sediment to settle at the bottom of a container can help improve the clarity of the water.
- After letting the sediment settle, carefully pour off the clear water into a clean container for drinking.

All of the above:
- It is recommended to use a combination of boiling, filtering, and sedimenting techniques to ensure that the drinking water is safe during a flood.
- By following these steps, you can minimize the risk of waterborne illnesses and protect your health.
