From the slums of Nairobi to the most remote corners of the Andes, clean water is a necessity. But without significant investment in sanitization infrastructure, this resource is incredibly difficult to provide. But after years of research and development, a cheap, reusable and nearly universally effective system of water treatment has been developed.
You can use stills in various areas of the world. They draw moisture from the ground and from plant material. You need certain materials to build a still, and you need time to let it collect the water. It takes about 24 hours to get 0.5 to 1 liter of water.
To make the aboveground still, you need a sunny slope on which to place the still, a clear plastic bag, green leafy vegetation, and a small rock (Figure 6-6).
If the water you find is also muddy, stagnant, and foul smelling, you can clear the water–
• By placing it in a container and letting it stand for 12 hours.
• By pouring it through a filtering system.
Note: These procedures only clear the water and make it more palatable. You will have to purify it.
To make a filtering system, place several centimeters or layers of filtering material such as sand, crushed rock, charcoal, or cloth in bamboo, a hollow log, or an article of clothing (Figure 6.9).
Rainwater collected in clean containers or in plants is usually safe for drinking. However, purify water from lakes, ponds, swamps, springs, or streams, especially the water near human settlements or in the tropics.
When possible, purify all water you got from vegetation or from the ground by using iodine or chlorine, or by boiling.
Purify water by–
• Using water purification tablets. (Follow the directions provided.)
• Placing 5 drops of 2 percent tincture of iodine in a canteen full of clear water. If the canteen is full of cloudy or cold water, use 10 drops. (Let the canteen of water stand for 30 minutes before drinking.)
• Boiling water for 1 minute at sea level, adding 1 minute for each additional 300 meters above sea level, or boil for 10 minutes no matter where you are.
Water is one of your most urgent needs in a survival situation. You can’ t live long without it, especially in hot areas where you lose water rapidly through perspiration. Even in cold areas, you need a minimum of 2 liters of water each day to maintain efficiency.
More than three-fourths of your body is composed of fluids. Your body loses fluid as a result of heat, cold, stress, and exertion. To function effectively, you must replace the fluid your body loses. So, one of your first goals is to obtain an adequate supply of water.
Water – when Tony asked me to pen a piece about water I pondered the content – how should I start it?
“Water, water everywhere and not a drop to drink!”? Nope waters to important a subject for so predicable and dull a start – so how about this …………
Without an adequate supply of safe drinking water you will die in one to three days – give or take a few days due to climate and activity ect ……….would that be a good start??
No one wants to die right?
For our native British ancestors water was the gateway to the spirit world, to the lands of their Gods. Into which they gave precious offerings and prayers. But, to modern man water has become a dumping ground, into which we throw our waste and chemicals!
In some parts of Sweden water can be drunk straight from the lakes, it’s safe and clean. Unfortunately over most of the rest of the world we have to purify our water before drinking it, to be safe.
Below are details of the main two nasties we are trying to avoid.
