Best locations to set up a solar still in the desert?

Choosing the Right Location

When selecting a location for your solar still in the desert, consider the natural flow of water. Look for low-lying areas where water tends to collect, such as depressions or swales. These areas can be found near the headwaters of a stream or river, where the water table is higher. A spot with a slight slope is also beneficial, as it will allow for better water collection and allow you to build a still that is partially submerged in water.

Building the Still

To set up a solar still, you will need a shallow pit or depression, a clear plastic sheet, and a collection container. Dig a pit with a diameter of about 10-15 feet and a depth of 1-2 feet, depending on the amount of water you need to collect. Place a clear plastic sheet over the pit, weighing it down with rocks or sandbags. As the sun heats the plastic, water will evaporate and condense on the underside of the plastic, dripping into your collection container.

Maximizing Water Collection

To maximize water collection, make sure your solar still is built on a south-facing slope with little to no shade. If possible, angle the still so that it is slightly tilted towards the south, allowing for better water collection. Use a series of shallow pits or a long, narrow pit to increase the surface area of the still, allowing for more water to be collected. By following these techniques, you can increase the efficiency of your solar still and collect more water in the desert.
