Solar Water Distillators

Solar water distillation replicates the way nature makes rain. Brackish or salty water is placed inside Solar Still via an inlet near the base of the Still. The sun's energy heats water to the point of evaporation. As the water evaporates, water vapor rises, condensing on the glass surface for collection. This process removes impurities such as salts and heavy metals as well as eliminates microbiological organisms. Solar stills can easily provide enough water for family drinking and cooking needs. 

The demonstration stills that will be constructed for 3 households in the project area are easy to replicate, using standard building materials, of which 95% are available locally "off the shelf". The still produces an average of 75 liters of drinking water per day in the summer months. Winter production is expected to be 1/2 that amount. There are no moving parts in the solar still, and only the sun's energy is required for operation. These types of solar distillators are already used in three communities of Georgia.
