You need to provide 1 gallon of water (3.7 liters) per person per day for you and each of your family members if you don't have access to clean water or a faucet.

Think about that for a minute. That's a lot of water. 

A half gallon (2 liters) is what you need for drinking each day - in warm weather or during periods of high stress or activity that amount could double.

Floods are perhaps the deadliest and most destructive of all natural disasters. The rush of water can destroy buildings, wash away cars and people in a matter of minutes.

They can happen anywhere: cities, towns, the countryside. Even desert dwellers can be surprised with flash flooding. 

You only need to watch a few videos to see what can happen in the extreme cases, and flash floods happen all the time in the US.
