Yearly Pantry, week 6: water

This week's challenge concentrates on water. Fill some water jugs or buy water purification tablets, as I intend to do.
In case of an emergency, water is vital. You can live longer without food than water. Tenzicut at Down to the Roots, who came up with this list, suggests 2 gallons a person per day for drinking and sanitizing.
When we lived in Tennessee for most of the time without running water, I can tell you that we can make water stretch because we know what a precious resource it is. We bathed, washed hands and cooked out of gallon water jugs that we filled at neighbors' houses or at the nearby park.
We have a large creek flowing behind our house so I'd like to have a store of water purification tablets on hand. I'll be ordering some from Emergency Essentials.
