How much water for 1 person per day?

Question

How much water do you need for 1 person for 1 day?

Answer 1

Experts say 1 gallon per person per day and that you should have 3 days stored at a minimum. But you really should have more - think of all the disasters where people don't have clean drinking water for a week or more! The last thing you want to do is run out of water.
