What is the least amount of water you could store per person per day? My rule has been one gallon but storing that much water for 8 people for 7 days is just too much in a dorm room. (The way these things are built the floor would give out) <img src="/images/graemlins/grin.gif" alt="" />

Soo...how much water do I need for just hydration per person per day with little to no activity?
