Sardar Vallabhbhai National Institute of Technology, Surat, India


For decades, researchers have been on a quest to find efficient ways to harness the natural resources of solar and water to help solve worldwide shortages of fresh water and electrical power.

The search for a solution is over. Solar desalination plants are now a reality thanks to the innovative and patented technology of Solar Water Energy. At Solar Water Energy, we provide Green Solutions for a Thirsty World.

A solar distillation system that will purify saline ground water is being installed at Sardar Vallabhbhai National Institute of Technology.

The solar desalination plant is made of steel and will have the capacity to purify up to 230,000 liters of ground water every 24 hours.

The desalination plant will meet all the needs of the institute, which anticipates future water shortages in the area. The cost of water supplied by the municipal corporation is approximately Rs 15 ($ .33 USD) per 1,000 liters. However, by sourcing its own water, the university will significantly reduce its water costs by two-thirds, to Rs 5 ($ .11 USD) per 1,000 liters.

This solar desalination plant has been in operation since May 2008, producing pure distilled water from saline ground water. It also is capturing and recycling the solar heat that is stored in the water. The stored energy can be converted to electricity using the ocean thermal energy conversion system.

The production capacity offered ranges from 26,400 gallons per day (100m3/day) to 105 million gallons per day (400,000 m3/day).

The cost of producing water is 1/10 of the cost compared to reverse osmosis.
