There are many ways to make the water drinkable even if we cannot be sure of its purity. Ιf we are getting the water from an unknown source, we can still purify it.
In order to purify the water, we need to process it through filters. If there is no way to determine if the water is drinkable, you will need to boil it.
What are the basic things we can do to make a homemade water filter, so the water will be drinkable regardless of the source we are currently getting it from?
1. Boil the water
The best way to make sure that water is safe is to boil it for ten minutes. The most difficult part is to be able to keep the fire strong for 10 minutes. This is a suggestion from most of the survival books and experts. Also, this spends a lot of time. It takes the time to lit the fire, to boil the water, to cool it so you can drink it. When all this is over, you have to start all over again.
If you do not have enough fuel and time, there is a way to purify the water in only five minutes. This method will work great unless the water is really dirty and muddy. If your fuel is limited, boil the water for one minute. This is much better than not boiling it at all. In the case of actual fuel shortage, simply heat the water to a boil, and most likely the water will be drinkable. Certainly, it will be safer than before.
Iodine is also a good way to disinfect dirty water. It just takes longer. Let iodine act between 30 to 60 minutes if it’s very cold. That’s why you should always have iodine drops in the box of first aid. Not only that it can be used for disinfection of a minor injury, but it also purifies the water.
Most iodine tinctures are sold in dark glass bottles. Pour a few drops to your water, stir it and wait about 30 minutes before consuming.
3. Filter the water
You can buy many kinds of filters which can be used whenever is necessary. Usually, we don’t have such a filtration system when we are going to nature, that’s why sometimes, we should know how to make our own homemade water filter. But it is required to get rid of the bugs and other residues from the water. In the case of water filtration need, you can improvise.
If there is a lot of water, like from a creek, it is advisable to let the water run through the filter long enough to rinse and refine any particles. Soluble filtering method will not kill or remove the parasites of the intestines but it will give the water a better taste and reduce the total amount of bacteria.
