Other Water Harvesting Methods:
By James Quaid
This is the second in our Water Solution Series. We’re going to be exploring Fog Fences and Solar Stills. These solutions are used typically in arid mountainous areas and deserts close to the ocean. The amount of water these devices collect depends on location, location, location.
The “Air Well / Dew Pond” was known to the Ancients, where they collected copious amounts of water in arid locations. See Wiki entry below.
In an emergency situation, a simple solar still can be constructed with some visquine plastic sheeting, a small shovel, and a container. Where you find dry wash or a creek bed, dig a hole in a low spot. Dig down far enough until you find moister soil. Put the container in the center of the hole, cover the hole with the visquine, and then put the excavated soil around the edges of the visquine to hold the visquine in place. Place a pebble in the center of the visquine directly above the container. This will channel condensation into the container. Construction should be done in the early AM, and by the late afternoon there should be liquid water in the container. Note: The 2nd video below uses a variation of this method.
