One of the biggest issues for many people if SHTF is going to be finding and maintaining a consistent, safe water supply. Though our planet is covered in water, only one half of 1 percent is drinkable! ……….

There are ways to make that water potable, though, and science is finding even more ways. In order to turn salt water into drinking water, you need to desalinate it first. That just means that you need to remove the salt. There are many methods for doing this but the most efficient and realistic way to do it at home in a survival situation is by using the distillation by evaporation method.

Distillation by Evaporation

One of the easiest ways to convert salt water to drinking water is by using heat. You simply heat the water until it turns to steam, then capture the steam.

………..

Evaporation Distillation Method 1

This is a simple method but won’t net much fresh water at a time. If you’re on the run or just need enough for a couple of people, it will work, though. You’ll need a metal cup heavy enough not to float or heat-resistant glass, a pot with a domed lid and heat.

Evaporation Distillation Method 2

This method for turning salt water into drinking water allows you to distill a bit more water though you’ll still be using quite a bit of energy. It operates on basically the same theory as an alcohol still. You’ll also need a heat-resistant glass or metal bottle, a cork or rubber seal for the bottle, a few of feet of tubing and a catch-basin.

Evaporation Distillation Method 3

This method is sort of a morphing of the two processes we’ve already discussed and may come in handy if you’re on the run and don’t have access to anything other than your camp pan. We always include aluminum foil in the list of things to keep in your bug-out bag and this is yet another use for it. You’ll need tubing too, so toss a few feet of it into your bag as well.

…………..

Along with desalinating water, all of the methods that we’ve described today also distill the water, effectively removing bacteria, viruses and other impurities from the water. If you’re using any of the solar methods, be sure to filter the water before you try to desalinate it because the process works best when the water is clear. Murky water will still work but it will take much longer.
