WATER TREATMENTWATER TREATMENT

POWERING EFFECTIVE
WATER & WASTEWATER SOLUTIONS

Water treatment is a vital component of the power and industrial sectors, driven by the need for sustainable operations and compliance with stringent environmental regulations. Effective water and wastewater management is essential to minimise ecological impact, and advanced technologies like Zero Liquid Discharge (ZLD) are increasingly being adopted to support water conservation and pollution control.

At L&T-S&L, our experts bring deep domain knowledge across a wide range of water treatment technologies, Thermal Desalination, MVC Desalination, RO, Chlorination, Oil Separation, Clarification, Sewage Treatment, SWRO etc. We have successfully engineered solutions for diverse water sources such as rivers, seas, borewells, and municipal sewage systems. With a focus on innovation and environmental stewardship, L&T-S&L delivers comprehensive water treatment solutions that meet evolving industry demands and support long-term sustainability.
