Why you need it
Water is the first thing to run short and the hardest to improvise. Three litres per person per day covers drinking and basic cooking, and having it already in the house means you never join the queue for it.
What to look for
Sealed bottles or food-grade containers holding three days' worth per person, kept somewhere cool and dark. Write the date on them and swap the stock out twice a year.
