Water is life. Everyone who has a prepper mindset has thought about the problem of
having safe water.
Unlike some parts of the world, in the US we are blessed with a large amount of fresh
water, however, most of it is not safe to drink untreated.
Most of us tackle this problem by buying filters. Nothing against them, I own a couple
myself. However, even the best of them will eventually stop working. Then what?
An acronym for a Swiss developed water disinfection program, SODIS is being used in
Africa to help prevent diarrheal illness in children. It is cheap, easy to use, and it
works. Using the ultraviolet radition from the sun.
Take a clear plastic water/soda bottle, peel off the label. Fill with water and let it
lay out in the sun for 6 hours.
The UVA radiation will kill all bacteria, viruses, and parasites. It works on cloudy days
as UV isn't stopped by clouds.
Remember how all the tree huggers talk about how our water bottles will sit forever in

You can use plastic bottles, glass jars, hell you could even fill a ziplock baggie with

water. Even if it does, the chemicals might kill you in a couple of decades. Montezuma's
Revenge can kill you in a week.
There are a couple of things SODIS cannot do. It can't desalinate water. And it can't
remove heavy chemicals or pesticides. If those are a concern then you need to construct a
