Water Usage & Risk Assessment

Water Usage & Risk Assessment

Regular assessments to track consumption patterns, identify high-usage areas, evaluate impacts on water quality, and enhance site-specific water management strategies

Key Initiatives

trailblazing

Robotic Cleaning for Solar Modules

We transitioned from water-based to dry robotic cleaning of solar panels.

Implemented at 7% more locations in FY 2024-25

436,175 m³ water saved in FY 2024–25

22% increase in annual water savings

innovative

Water-Efficient Construction Practices

To reduce water in concrete curing, we use curing compounds that retain moisture without additional water.

Successfully piloted in FY 2022-23

Achieved 59% water reduction compared to conventional curing.

Rolled out at 8 sites in FY 2024-25
