How to Clean Water for Survival Using A Filtering Tripod, Solar Still, and a Transpiration Bag

Filtering and Purifying Water in the Wild

Water purification and filtering methods in the wilderness. No matter where you are you will need water. There is almost always a way to obtain it. You just have to know how to extract it from the land around you. Many times there is plenty of water around, it is just dirty water unsafe for consumption. There are often times very dangerous parasites in unfiltered water sources. Learn here how to obtain clean, potable water using natural filter making techniques.

Make A Solar Still For an Emergency Water Source

Purifying Water in a home made Solar Still for Survival.

In a Desert finding water can be a real task, and near the ocean finding fresh water can also be difficult. The Solar still will allow you to get every possible drop of it. In most survival situations it would be a good idea to make as many of these as possible, because this does not produce a lot of water. But it does produce water when there is no other alternative. Using this method you can not only convert your own urine into potable water, but you can actually desalinate saltwater for drinking. This will make extremely clean water. Any metals, salts, bacteria etc. will be eliminated. When the water is evaporated from the ground, into your solar still, the elements that you cannot drink are left behind.

To make the solar still you will need a cup or something to catch water, a plastic sheet, or bag, and a couple rocks.

  1. You will need to dig a hole in the ground. Try to find a spot that will likely be moist.
  • ​Place your water receptacle directly in the center of the bottom of the hole.
  • ​Lay your plastic sheet over the hole.
  • Put a rock, or something small and somewhat heavy in the center of the plastic. This will make a low point to concentrate the water to this spot, where it will drip into your cup below.
  • You will also need a few rocks, to put around the top of the plastic to hold it secure.  You could also use dirt if you needed to.

Around the perimeter of your still you should dig a shallow trench. This will be where you will deposit your urine (if the ground has little to no moisture content).  You would also pour saltwater into this trench. Make sure to dig you trench about 12″ from your still, so that the water flowing into it to be evaporated will already be filtered by the sand and dirt.  You can also shred up vegetation and put it into your still. The sun will extract the moisture from these plants as well.

How to make a Water Filter Tripod

Filter water using natural materials in a water tripod filtration device.If there is ever a time where you are in a survival situation and you need water, this is a great way to make pure clean drinking water out of easily found materials.

Filter water with just sand, charcoal, grass, and a few pieces of cloth or towels

  •  You will start by making a tripod out of three logs or large sticks. Tie your towels or cloth material in three layers on the tripod.
  •  The first layer will be grass, this is used to remove the largest material. The water will quickly move through this layer.
  •  The second layer of your home made survival filter is sand. This will remove the smaller impurities in the water.
  • The third and final layer is charcoal from a recent fire. You will want this to be well burned coals. This layer works to remove any final impurities that are in the water, also will improve the taste and odor of the water.

This will remove most problematic things from the water, but you will still need to choose your water sources carefully. This will likely not remove giardia, or cryptosporidium.  Try not get water from sources where there is a strong likely hood of animal feces in the water.

How to make a Transpiration Bag

The Transpiration bag is a very effective and easy way to secure water in almost any environment during a survival situation. Anywhere there is vegetation, it can be done.Making a Transpiration Bag to clean water to drink.

As you can see in the image it is a very simple procedure. Wrap a bag around leafy branch on a tree. Tie the bag on with rope or string so none of the moisture can escape. The condensation should begin to accumulate in the bag shortly after the sun starts to beat on it. You can easily Put several of these on one tree. The branch does need to be in full sun for this to be effective. Please make sure that the tree is not poisonous! Poisonous trees will equate to poisonous liquid.
Place a rock in the bottom of the bag in the corner. This will encourage the water to all end up in one corner and make it easier for you to extract. There are a couple different ways to get the water out of this. You can either run a straw or a reed through the top of the bag down into the water, or you can cut a corner off the bottom of the bag and let the water pour out. Be sure to tie this hole off before you walk away, otherwise there will be no water there the next time you come by.

 

What is Transpiration?

Transpiration is the evaporation of water from parts of plants, especially from leaves but also from stems and flowers.

A fully grown tree might lose hundreds of gallons of water through its leaves on a hot day. About 90% of the water that enters a plant’s roots is used in the transpiration process.

Using the above filters and purification methods you should be able to clean water in almost any environment. Knowing how to clean water is an important skill.
