Tata Steel Kalinganagar Cuts Freshwater Use by Over 40%

29 Jul 2025 CW Team

Tata Steel Kalinganagar, located in Jajpur district of Odisha, has achieved a significant milestone in water conservation by reducing its freshwater consumption by more than 40 per cent through the adoption of advanced water management technologies and sustainable practices.

According to the company, the reduction is the result of multiple process optimisations and the implementation of cutting-edge technologies over the past seven years. Key initiatives include the installation of a Central Effluent Treatment Plant with High-Efficiency Reverse Osmosis, Mechanical Vapour Recompression (MVR) systems, and a BOD (Biological Oxidation and Dephenolisation) Plant with tertiary treatment capabilities.

Rainwater harvesting and zero discharge practices

In a further commitment to water stewardship, the plant has developed a ‘Rainwater Harvesting-cum-Percolation Pond’ spread over 10,500 square metres, with a water storage capacity of 46,000 cubic metres and a green cover of over 10,000 square metres. This initiative is designed to enhance groundwater recharge and ensure efficient utilisation of rainwater.

Tata Steel Kalinganagar also operates as a ‘Zero Effluent Discharge Plant’, ensuring that all water used in operations is treated through advanced effluent treatment systems and fully reused within the facility. No untreated water is released into the environment, underlining the plant’s focus on responsible water use.

Integration of renewable energy

As part of its broader sustainability strategy, the plant has integrated renewable energy into its operations through the commissioning of a 10.1 MWp floating solar power project on its reservoir, further reducing its environmental footprint.

These efforts collectively position Tata Steel Kalinganagar as a benchmark for sustainable industrial practices within the steel sector.
