Water Filtering Devices

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 still 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.

Remove the odor from water by adding charcoal from your fire. Let the water stand for 45 minutes before drinking it.
