Minjur Seawater Desalination Plant, water desalination plant in Kattupalli, Chennai, India
Minjur Seawater Desalination Plant is a facility in Tamil Nadu that converts seawater to drinking water, located on the coast of the Bay of Bengal. The plant uses reverse osmosis technology with high-pressure pumps to remove salt and impurities from seawater, producing about 100 million liters of clean water daily.
The project was approved in 2005 with construction beginning in 2007 and completion in 2010, making it the largest facility of its kind in India at that time. A cyclone during construction caused delays, but the plant was successfully built by local and international companies and was to be operated by a private partner for about 25 years.
The facility is named after the nearby Minjur locality in Chennai. It represents how the city has adapted to water scarcity and shows the daily work of operators who maintain the machinery that keeps water flowing to homes and businesses.
Visitors should follow designated routes and obey all instructions from staff to stay safe and avoid interfering with plant operations. It is best to check ahead about current visit conditions, as the facility sometimes undergoes technical maintenance or operates at reduced capacity.
The plant uses energy recovery devices that capture and reuse power from the high-pressure brine waste, lowering operating costs. This innovative approach shows how modern water technology can reduce both expenses and environmental impact while solving urban water needs.
