The Nemmeli (India) desalination plant is officially inaugurated with a capacity of 150,000 m3/day
  • This is the country’s largest seawater desalination project for municipal use, fully developed by the consortium formed by Cobra-Tedagua and Tecton, with a production capacity of 150,000 m3/day.
  • This is an emblematic project, which has a robust pretreatment that guarantees its total reliability and ability to cope with the effects of Climate Change.On February 24, the inauguration of the Nemmeli Desalination Plant took place, located in the city of Chennai (India).

This is the most significant project in the country in terms of seawater treatment, fully developed by the consortium formed by Cobra-Tedagua and Tecton for the Chennai Metropolitan Water Supply and Sewerage Board (CMWSSB). It has a production capacity of 150,000 m3/day of drinking water that provides desalinated water supply to more than one million people in one of the most populated areas of the world.

The event was presided over by the Chief Minister, the highest authority of the state of Tamil Nadu, who was able to see first-hand the state of the facilities and the water production process along with the rest of the local authorities.

This is a project with a design based on the reliability of the installation, featuring a versatile pretreatment that includes lamellar sedimentation, DAF, ultrafiltration and the usual chemical adjustments. This makes the plant increase its adaptation against poor raw water qualities or even sudden influent variations. All this, together with a low electricity consumption, makes it one of the most robust plants to reduce the carbon footprint against the effects of Climate Change.

The project also includes the marine work with an inlet pipe of 1 km and an outfall of 600 m in length.

The water will be distributed to 14 urban areas in the south of Chennai, benefiting a densely populated area with limited access to quality water resources and exposed to water scarcity. The close collaboration between Tedagua and all related actors has made this execution a success, starting its operation for a period of 20 years, where it is expected to improve the standard of living of more than one million inhabitants.
