If water pipes are damaged, contact the water company and avoid the water from the tap. You can obtain safe water by melting ice cubes. If your well has been flooded, assume the water in your home has been contaminated. Follow the directions on the right side of this page to disinfect your well. If you are on public water, your local health jurisdiction will let you know, through local media, if your water is not safe to drink.
Bottled water is the best choice.
If you can, get commercially bottled water that has been stored for less than 6 months in tightly sealed containers. Plan for one gallon per person per day. If the water from your tap is clear- Boil it for 3 minutes to disinfect. If water is cloudy - Filter it by pouring it thru a coffee filter and then boil it for 3 minutes. Let it sit for 1 hour.
