The inadequacy in supply and the shortage of clean potable water has taken centre stage in recent times. The first half of the year 2016 is already witnessing huge water scarcity in many part of the country. High growth of population coupled with rapid industrial developments in Indian subcontinent resulted in shortage of clean drinking water for people living in rural areas and remote villages especially in desert. In urban and rural areas surface or ground water is polluted due to industrial waste or rampant use of chemicals in agriculture (e.g. insecticides, pesticide and chemical fertilizers). Other dimension to the problem is acute shortage of power supply for running traditional water cleaning systems such as reverse osmosis. One of the prominent economical methods of converting the saline water to potable water is solar desalination. It distils the saline water by evaporation and condensation the way nature makes rain. Here in this paper, the goal is to provide an overview of conventional as well as solar desalination technologies available at present.
