TRANSFORMING TRANSFORMING TRANSFORMING SUSTAINABILITY REPORT FY 2023 COMMUNITIES THE PLANET THE WORKPLACE Jharsuguda smelter: A national benchmark in water efficiency Vedanta Aluminium's Smelter-1 located at • Revamping of dual media filter for STP Future plans Jharsuguda, Odisha, has emerged as a leading to increase in amount of water Given the high carbon footprint of national benchmark in water efficiency recycled smelters, the water wins achieved among aluminium smelters in India. 3 at Jharsuguda come as a beacon √ Impact: 0.01 m Through various initiatives and /MT of hope for our business and the investments, the smelter has successfully industry at large. We have minimized its water footprint, maximized The cumulative savings are to the tune of ambitious plans of amplifying and 3/MT of water and has positively water reutilization, and reduced its 0.06 m optimizing these positive results specific water consumption. contributed to the overall water to drive even greater impact. We efficiency of the smelter. intend further increasing the The milestone has been achieved through rainwater utilization through the several initiatives, and these are: Magnetic float valve installed in all end users' installation of a lift pump in the Sintex tanks to minimise water wastage SWPH Reservoir, with a target of • Installation of storm water utilization 3 achieving 0.04 m system to increase usage of recycle /MT savings. water Additionally, plans are underway Fire Water line placed above ground to to install Reverse Osmosis (RO) √ Benefits achieved: Reduction of minimize the fire water leakages and Multiple Effect Evaporator freshwater consumption (MEE) systems with a capacity of 3 200 cubic meters per hour √ Impact: 0.03 m /MT 3 (m /HR). In the short term, the • ETP sandbed replacement to increase focus is on minimizing firewater ETP efficiency leakages by implementing √ Benefits achieved: Increase in recycling above-ground firewater lines. water percentage √ Impact: 0.02 m3 /MT 67
