Vedanta Aluminium Business has recycled 12.5 billion litres of water as of February during FY 2022-23. The company has undertaken the groundbreaking ceremony of a new Sewage Treatment Plant (STP) with a processing capacity of 440 kilo litres per day (KLD), at its mega aluminium smelter in Jharsuguda. Once operational, the treated water from the facility will be reused within the plant premises, reducing fresh water consumption by 15 crore litres per year. This reiterates the company’s commitment to become ‘Net Water Positive’ within the decade, leveraging advanced technologies for efficient water utilisation and community participation towards building a sustainable water footprint.
According to Rahul Sharma, CEO, Vedanta Limited, Aluminium Business, the company recommits to its mission of becoming Net Water Positive and ensuring a sustainable water footprint in the regions where they operate. The quality of lives and business sustainability is contingent on the planet and hence, excellence in ESG (Environment, Social & Governance) forms the bedrock of the organisation’s aspirations. Water is a critical shared resource that is crucial to sustaining the ecology and communities around, and hence, Vedanta’s endeavours are aimed at ensuring the sustainability of its operations and making more water available for local communities and biodiversity.
As per Ajay Pandey, COO, Power, Vedanta Jharsuguda, Vedanta’s operations maintain a laser-focus on ensuring the judicious usage of precious water resources. By deploying a strategic mix of resource conservation and source rejuvenation programs, the company has been successful in achieving a steady improvement in its water management efforts. The new Sewage Treatment Plant provides an additional fillip to the efforts in this regard and will help accelerate the company’s roadmap to water positivity.
The company has a structured four-pronged approach to water sustainability, which involves:
Robust monitoring of water usage:
- Water management is integrated into decision-making processes for all projects
- Water-related risk assessments have been carried out to identify the degree of water stress, and accordingly, undertake mitigation measures
- All water quality parameters, including reduction of specific water consumption, are strictly monitored
- Quick Response Teams respond to extreme weather conditions, including unprecedented heavy rainfall
- Internet of Things (IoT) and other leading-edge technologies deployed for efficient and automated water management
Ensuring maximum water reutilisation:
- Stringent control measures and technologies adopted to ensure zero discharge operations
- High-Concentration Slurry Disposal (HCSD) system deployed for ash management to ensure maximum water recycling through feedback loops
- Operational excellence in cooling tower systems have resulted in one of the best Cycles of Concentration (COC) globally; higher the COC, less is the additional freshwater intake
Creating a positive water footprint:
- Partnership with TÜV SÜD, a global leader in sustainability solutions, for creating the roadmap for Vedanta Aluminium to become net water positive
- Rainwater harvesting infrastructure and on-site water reservoirs created for water sourcing during contingency scenarios
Working with local communities:
- Restoration and rejuvenation of over 40 community waterbodies in the vicinity of its operations in Chhattisgarh and Odisha in this fiscal alone
- Training communities on growing climate-resilient crops and adopting better methodologies (like SRI technology in paddy cultivation) for improving yield in the face of irregular climatic conditions
- Helping local farming communities adopt drip-irrigation, treadle pump, solar powered water pumps, rainwater harvesting structures like percolation tanks, etc. to boost irrigation potential and reduce dependence on monsoons for cropping
- Construction of hundreds of community water infrastructures like check dams, tube wells, bore wells, farm ponds, percolation tanks, etc. to help communities get perennial access to water for household and irrigation purposes
- Integrated watershed management benefiting thousands of communities through livelihood creation, capacity building, new livelihood opportunities and more
On World Water Day, the company had organised an interactive session with Ramveer Tanwar, popularly known as the ‘Pond Man of India’ and a noted pond conservationist, to encourage employees and community members to work towards water conservation in their personal and professional capacities
