Creating Water-efficient Infrastructure

TCS’ green building-compliant premises use less water, fully recycle sewage, and harvest rainwater.


Water is material for the operational sustainability of every large corporation, including TCS. Our water conservation plan is based on design efficiency, water treatment, recycling, and replenishment. To achieve its ambitious goal of achieving water neutrality by 2020, TCS has implemented water-efficient fixtures at new offices and campuses, ensuring 100% treatment and recycling of sewage and rainwater harvesting. Sewage is treated using state-of-the-art technologies and recycled for use in HVAC cooling towers, flush tanks, and irrigation (in that order). Employee engagement also plays a big role in our water sustainability strategy.

Water Performance (baseline year 2007-08):

  • Specific water consumption reduced by 14.59%
  • 7.5 million kL of water recycled
  • 598,227 cubic meter of rainwater harvesting potential created
