Abstract: “Water plays a key role in our day to day life. A common man tend to use about 250 litres per day. Due to poor rainfall and contamination of the ground water the source of fresh water is decreasing drastically. Thus the alternative method for the source of water is by, Conversion of Sea water in Fresh water. The normal conversion of sea water into drinking water is tedious and costly. Thus an alternative method is used to remove salt from the water. The Boiling point of liquid under vacuum condition or low pressure is generally low. Thus this process involves Evaporation and Condensation of sea water, which is done under Vacuum condition, by using only Natural resource as the main source of energy. The major source of energy used in this process is solar energy. Solar water heater is used for producing the heat needed for the Evaporation zone and Sea water is used for cooling purpose in Condensation zone. The solar energy used to generate electricity, which is used for Conversion of Sea”
