CASE STUDY: LEADING WITH WATER POSITIVITY | MAHINDRA SUSTEN Overview Mahindra Susten has set a new benchmark in sustainable infrastructure by becoming 100% water positive across its portfolio, with independent validation from TÜV Nord in FY24. Recognising the intensive water demands of solar operations—a typical 1 MW plant consumes up to 8,000 litres of water monthly, comparable to a household’s consumption—Susten reimagined its practices to eliminate its water footprint and deliver regenerative impact. The Journey to Water Positivity • Phase 1: Construction Efficiency (2019–20): Introduced concrete and high-efficiency spray pump admixtures, resulting in reduced water usage during civil construction. • Phase 2: Robotic Innovation (2020–21): Deployed robotic dry-cleaning technology to eliminate water use in solar module cleaning, replacing traditional wet methods. • Phase 3: Replenishment and Recharge (2021–22): Implemented scaled rainwater harvesting and recharge systems through artificial ponds and percolation techniques across sites. 15x Water Positivity Index Returning 15 times more water than consumed 67 Million litres saved annually in the operational phase 30% 30% reduction in water usage per MWp during construction WATER SECURITY & CONSERVATION Water stewardship is not merely an operational focus but a strategic pillar of our Planet Positive agenda. We are committed to achieving water positivity by 2030, ensuring we replenish more water than we consume. This ambition strengthens our resilience to water stress, mitigates operational risks, and advances our Zero Liquid Discharge (ZLD) goal. Our integrated approach includes proactive leak detection, deployment of water-efficient technologies, rainwater harvesting, and large-scale community water rejuvenation projects. KEY PRINCIPLES GUIDE OUR WATER STEWARDSHIP APPROACH: • Efficiency: Optimising water use within operations through technologies, real-time leak detection, and reuse systems. • Replenishment: Investing in rainwater harvesting, aquifer recharge, and watershed restoration. • Collaboration: Supporting community water rejuvenation efforts to create shared value. KEY HIGHLIGHTS OF FY25: • Tech Mahindra: 291 million litres of water reused in FY24 and earned an ‘A’ Leadership score from CDP for Water Security. • Mahindra Susten: Achieved 100% water positivity at the portfolio level and is on track to reach the same milestone at the project level by FY26. • Mahindra Lifespaces: Targeting net-zero water use and water-positive developments by 2030. • Mahindra Logistics: Continues integrating sustainable water practices across its operations and infrastructure. Note: Due to increased production, total water consumption are higher in FY25 compared to FY24. This year’s scope has been expanded to include area offices, which has contributed to a decrease in the overall percentage of water recycled/reused. Total Water Consumption (m³) Water Reused/ Recycled percentage 21,62,342 39% 28,80,263 34% FY24 FY25 Environmental KPIs Rise For A More Equal World | 57 MAHINDRA & MAHINDRA LTD.
