|Approved water storage containers|
"You should store at least one gallon of water per person per day" and to Keep at least a three-day supply of water per person." "A normally active person needs at least one gallon of water daily just for drinking however individual needs vary, depending on age, physical condition, activity, diet and climate." http://www.ready.gov/water
However, I would suggest it is more advisable to store at least:
3 gallons of water per person per day
and to keep at least:
5 day supply of water per person
This will better account for drinking, sanitation, and possible medical emergencies.

CHARLESTON, W.Va. (AP) - A chemical spill left the water for 300,000 people in and around West Virginia's capital city stained blue-green and smelling like licorice, with officials saying Friday it was unclear when it might be safe again to even take showers and do laundry.
...For now, there is no way to treat the tainted water aside from flushing the system until it's in low-enough concentrations to be safe, a process that could take days.
...People across nine counties were told they shouldn't even wash their clothes in affected water, as the compound can cause symptoms ranging from skin irritation and rashes to vomiting and diarrhea.
...The spill brought West Virginia's most populous city and nearby areas to a virtual standstill, closing schools and offices and even forcing the Legislature to cancel its business for the day. Officials focused on getting water to people who needed it, particularly the elderly and disabled.
