Water Resiliency
Water-resilient strategy
Water: A shared resource, a shared responsibility
Our Net Zero Water approach focuses on reducing demand through low-flow fixtures, treating and reusing wastewater via on-site STPs, harvesting rainwater for recharge or reuse, and installing smart water meters to influence user behaviour. Water is a critical resource across the lifecycle of our residential projects—for construction, dust suppression, and during occupancy. In our IC & IC business, we provide utility services to industrial clients, where reliable water access is essential. Given India’s growing urban footprint and declining water reserves, we prioritise water-secure developments. Water is sourced from rainwater, borewells, municipal supply, tankers, and treated wastewater. Our water sustainability strategy involves classifying sites as groundwater stressed or non-stressed, enabling tailored mitigation plans integrated across the project lifecycle—from design to post-occupancy. We also conduct hydrogeological studies to assess groundwater recharge potential and hydrological study to identify flood risks and decide mitigation measures. Our approach to water conservation is both strategic and site-specific. It is embedded early in our project lifecycle; it begins right from site selection and extends through design, construction, and occupancy. Through this integrated strategy, we aim not just to reduce our dependency on freshwater but also to build resilience for our communities and future developments.
