Tata Projects had earlier designed, supplied, installed and commissioned on turnkey basis a seawater desalination plant to produce potable water of a capacity of 2.4 million litres per day to cater to the requirement of an industrial colony in Kudankulam in coastal Tamil Nadu for Nuclear Power Corporation of India. This desalination plant draws water directly from the sea and is in successful operation from November 2002 for Phase-I and from April 2004 for Phase-II. 

The company has also developed a mobile sea water desalination plant of 4000 litres/hour capacity which is first of its kind in the country. The company has recently developed a de-fluoridation plant of 1000 litres/hour capacity for removing fluorides and arsenic to provide safe drinking water, which is under successful operation at Gangadevapalli village of Warangal District in Andhra Pradesh. 

Close on the heels of these developments, Tata Projects has now secured a prestigious EPC contract from Nuclear Power Corporation of India Ltd. for the execution of 7680 cu.m. per day seawater desalination plant with an extended O&M period of five years, to be implemented within 20 months at Kudankulam in coastal Tamil Nadu. This plant will cater to the need of DM and potable water requirement of the 2000 MW Nuclear Power Plant project. This will be the first sea water desalination plant adopting multi-vapour compression (MVC) technology in India. The contract value is over Rs 1000 million.
