At L&T, water consumption is primarily driven by industrial activities associated with the execution of EPC project contracts, especially in civil works. In contrast, water usage at manufacturing facilities remains minimal. We have adopted multiple conservation strategies to minimise water consumption across our operations. These include installing water-efficient fixtures, regulating water pressure in pipelines and controlling system losses. Innovative construction practices like curing compounds and steam curing are also being implemented to reduce water usage at project sites.
Recycling and reuse are central to L&T’s water stewardship efforts. Greywater and blackwater recycling systems are promoted across work locations, with treated wastewater reused for landscaping, toilet flushing, dust suppression, equipment cleaning and fire-fighting systems. In addition, rainwater harvesting and groundwater recharge initiatives are being actively explored and implemented wherever feasible.
Wastewater from EPC project sites generally contains only suspended solids and is not characterised by high-effluent content. Nonetheless, we ensure responsible wastewater management by implementing Zero Liquid Discharge (ZLD) systems at our manufacturing units and select project sites. These are supported by Effluent Treatment Plants (ETPs) and Sewage Treatment Plants (STPs). At other locations, wastewater is either treated on-site or managed through authorised third-party service providers, ensuring minimal environmental impact. To improve data collection and reporting, particularly at EPC project sites, we have started installing flowmeters at various sites and enabled data flow automatically to the data management system.
