|White Orange Juice Containers of Water|
When the water is frozen, put them in your refrigerator. Put MORE in the freezer and when those are frozen, leave them there.
If your power goes out the jugs and bottles of water will help keep your food cold and thus be available to eat. If you run out of water you can defrost the frozen jugs and bottles and bingo, there's fresh clean water for drinking.
And if you happen to have empty space in your freezer, keep some jugs or bottles of water in there all the time, don't wait for a storm warning. This will not only provide you with instant water and a method of keeping food cold, it also saves energy because a full freezer doesn't have to work as hard.
