Va Tech Wabag, a water technology company, has won a design, build, operate order from Chennai Metropolitan Water Supply and Sewerage Board for building 400 million litres per day sea water reverse osmosis desalination plant at a total cost of about Rs 4,400 crore.
The project has been funded by Japan International Cooperation Agency (JICA) and seeks to improve Chennai’s water security through a stable source of drinking water in the form of desalination.
The project will be executed by WABAG in a joint venture with Metito Overseas Ltd. Once completed, the project will be the largest desalination plant in the South East Asian Region.
The contract includes design, engineering, procurement, construction, installation, testing, and commissioning of the 400 MLD SWRO desalination plant and the associated sea water intake system over 42 months followed by 20 years of operation & maintenance, according to a statement.
The desalination process will include lamella clarifiers, a dissolved air flotation system, and gravity dual media filters followed by reverse osmosis and re-mineralisation to produce clean drinking water which will be further distributed by Chennai Metropolitan Water Supply and Sewerage Board to the residents of South Chennai.
