India’s first offshore desalination plant to set up in Tamil Nadu

India’s first offshore desalination plant will be set up by the National Institute of Ocean Technology (NIOT) about 40km from the Ennore coast in Tamil Nadu with a capacity of about 10 million litres of water per day.
The Detailed Project Report (DPR) for the plant, which is estimated to cost Rs 2,000 crore, has been submitted to the Centre for approval. The offshore plant is designed and built by NIOT scientists.
The plant will operate on the indigenously developed Low Temperature Thermal Desalination (LTTD), a low cost and environment friendly technology to get potable water. The technology is based on the temperature difference in seawater at different depths.
