Belowground Still Water

It is possible to draw moisture from the ground and plant material. This moisture, which is water, obviously would be essential to your survival.  One can do so via stills(water). You can use these in various parts of the world. Certain materials you will need to build so.

Furthermore, you will need time for them to collect. A day could get around a half to a whole liter of water. And this does so passively, so it gives you time to do other things. For this post, we will talk about building or making a belowground still.

Belowground Still: Preliminary

To make the belowground still to passively collect water, you are required of a tool for digging, a container, a transparent plastic sheet, a drinking tube, and a stone or rock.

You will need to select a site where you suspect the soil will contain moisture. Such as these are a dry steam bed or low spot where rain collects into. The soil should be easy to dig. Furthermore, light should be shining on the spot for most of the entire day.

Belowground Still: Main Steps

Start by digging a hole that is shaped like a bowl around a meter across and 60 centimeters in depth. At the center of the hole, dig then a sump. How deep it is and its perimeter is reliant upon the size of the container that you are to place inside of it. The bottom should also allow the container to stand erect.

Next, anchor then the tubing to the bottom of the container by forming a loose overhand knot in it. Afterwards, place the container upright in the sump. Extend the end unanchovered over the hole you made. These edges you must cover with soil so that it holds in place.

That center then you will need a rock placed at the center of the sheet of plastic. This sheet you then will need to lower into the hole. This you must make 40 centimeters below ground level. This now will form a cone inverted – at its apex the rock. Make sure this cone apex is directly on top of your container and that the palstic cone is not touching the sides of the hole. In regards to the touching, if so, the earth will be able to absorb the condensed water made.

Anyways, follow this all up by putting more soil on the edges of the plastic. Doing so to hold it in place and make it so that does not lose moisture.

Plug the tube whenever not used. If you do not do so, moisture will escape and evaporate.

You can drink water from this still without having to touch it through the use of a straw or similar tube.

Belowground Still: Additional

Plants are sources of moisture you can use in the hole. You can do this by digging out extra soil from the sides of the hole you made, so as that it forms a slope. Here, you place the plants.

If no more than polluted water is round, you can do the following. Try and dig a small trough just outside your around 25 centimeters from the lip of the still. Dig this 25 centimeters deep and 8 centimeters wide. Pour then the polluted inside of the trough recently made. Make sure, that no polluted water is spilled around the hole’s rim where your plastic sheet makes contact with the soil. Through these steps, you can get the trough to hold polluted water and soil to filter it. Whereas water then condenses onto your sheet and then drains into the set up container.  This works especially well when you only have salt water around.

You may need three stills to sustain yourself.
