I said in a recent post that one person requires 1 gallon of water a day on average for drinking, cooking, basic cleaning and grooming. Of course, under normal circumstances, we use many times this amount.
In a survival situation, this would mean that you need 30 gallons per person for a month. Bottled water often comes in 1/2 liter bottles (16.9 oz) and a case of 24 would give you about 3 gallons. So, for one person that would be 10 cases of bottled water per month. For a family of 4 it would be 40 cases for a month supply.
For a year, you would need 500 cases. Of course, water is not something that you need to store a year supply of. You need to have enough on hand to get you through a short-term emergency.
I recommending storing water for a week which is 28 gallons for a family of four. And if you start worrying about the water supply, you can fill up the bathtubs and cooking pots in your house beforehand. If you have a freezer that is not full, you should make it full with 1 gallon milk jugs of water that will freeze into large 1 gallon blocks of ice. If power goes out, your freezer will stay cold a lot longer if it filled with blocks of ice than if it is half empty. And you can drink the water later, or use it to cook.
After that initial period, if there is still a water problem, you need to have the supplies and know-how to purify your needed water from natural sources.
Ways to make water drinkable include:
- coffee-filter and boil
- chemical treatment
- high-tech filtration
We will discuss each of these in future posts…
