Vedanta Aluminium recycles ~14 billion litres of water

Vedanta Aluminium Business, India’s largest producer of aluminium, has recycled 14 billion litres of water as of January 2022, leveraging advanced technologies for focused control and monitoring of water consumption.

Their water sustainability efforts are guided by its robust Water Management Policy. In line with the company’s commitment to the 6th UN Sustainable Development Goal – Clean Water and Sanitation, they strive to ful-fill its water sustainability goals in three ways – increasing water reutilisation, reducing freshwater consumption, and ensuring zero liquid discharge from operations. They are also working with local communities and farmers in the regions where it operates to construct water harvesting and conservation infrastructures for perennial water supply, to boost irrigation potential and reduce dependency on monsoons for cropping. 

With this year’s World Water Day theme of ‘Groundwater: Making the invisible visible’, Vedanta Aluminium has undertaken robust measures to optimise water consumption across its value-chain and increase the share of recycled and reused water, such as:

• Water-screening assessment to develop and implement stringent control measures to ensure zero discharge operations. 
• Deployment of High-Concentration Slurry Disposal (HCSD) systems in ash management, which ensures maximum water recycling through feedback loops. 
• Regular water consumption-related audits, and appropriate measures to ensure continually improved performance. 
• Optimisation of freshwater intake by maximising usage of water recycled through Effluent Treatment Plants (ETP), augmented with Ultra Filtration (UF) and Reverse Osmosis (RO). 
• Rainwater harvesting infrastructure and on-site water reservoirs have been created for water sourcing during contingency scenarios.

Working towards sustainable livelihood and climate impact mitigation, the company is building hundreds of community water infrastructure to help communities get perennial access to water for household and irrigation purposes.
