Water Management

Recognizing the need for Water conservation, Infosys has chosen to move beyond mere compliance, embedding water conservation and restoration into our water strategy. Aligning with our climate-positive goals, Infosys has turned this challenge into an opportunity by transforming our campuses into hubs of water regeneration. Through large-scale recharge initiatives, we have sequestered billions of liters of water, revitalized local ecosystems, and enhanced water availability for surrounding communities.

As a signatory to the UN Global Compact’s CEO Water Mandate in 2014, we recognize that responsible water stewardship is both an operational need and a societal responsibility. To this effect, we have enhanced our initiatives around water conservation, efficient water use, rainwater harvesting, and maintaining zero wastewater discharge across our owned campuses in India. Wastewater from international locations and leased sites in India is responsibly discharged into municipal sewer systems, in compliance with local regulations.

Risk Response

Risk assessment enables Infosys to understand its water related vulnerabilities while shaping a comprehensive response strategy that considers location specific challenges with a long term perspective. Our assessment framework includes hydrological and hydrogeological studies, climate-variability analysis, infrastructure resilience, and community impact. Using tools such as the WRI Aqueduct, we assess water risk across all locations and implement actions that are socially equitable, environmentally sustainable, and operationally efficient. By adopting a risk to response approach, we gain a more nuanced understanding of water risks and identify opportunities for value creation. We manage water in ways that are fair for people, protect the environment, and make good economic sense.

We aim to make the campuses water sustainable. We continue our focused efforts to reduce freshwater sourcing and aim to achieve water positivity through our 3M and 7R approach. 3M (Map, Monitor, Measure), 7R (Reduce, Recycle, Recover, Recharge, Rejuvenate, Recognize/Respect)

Water is managed in the following ways:

• Rainwater harvesting at scale.

  Rainwater harvesting is an important part of our water stewardship goal, and rooftop rainwater harvesting, harvesting tanks, recharge wells, and artificial lakes are built on India campuses to reduce external freshwater dependency and help replenish the groundwater table in the communities we operate. We continue our efforts to extend this initiative across locations to optimize freshwater consumption. Roof-top rainwater harvesting systems have been installed on most campuses, helping us reduce freshwater consumption. Roof rainwater harvesting has been highly beneficial for offsetting freshwater consumption from external sources. This is an initiative we have as a long-term target to achieve water positivity.

  Our campuses function as groundwater recharge zones, channeling millions of liters back into depleted aquifers.

  • 405 deep injection wells strategically installed across India campuses with a combined recharge capacity exceeding 20 million liters
  • 40 artificial lakes created with a 430 million-liter holding capacity, designed not just for storage but as active recharge systems
  • Surface runoff harvesting during monsoons directs rainwater into underground aquifers through engineered infiltration systems

  Treated wastewater from STPs is channeled to recharge wells, ensuring every drop serves dual purposes. We ensure seamless and efficient operations through maintenance, installation, or upgradation of water treatment systems across locations to treat water to the necessary levels (e.g., Softener, reverse osmosis) and repurposing the same.

• Smart infrastructure and technology

  We leverage technology to monitor and manage our water consumption efficiently. Smart water metering systems across most of our campuses enable early detection of issues such as leaks and blockages, reduce unaccounted water, identify conservation opportunities, and generate insights that inform future facility designs. These meters are integrated into our central monitoring platform, allowing us to track water flow and real time consumption patterns with greater accuracy and control.

• Smart irrigation systems

  Smart irrigation systems are piloted at a few of our campuses. We are evaluating this project and plan to expand it gradually across other campuses. Additionally, we are working to reduce lawn cover and increase tree cover to lower irrigation water demand. Our other initiatives include using native species and continuing to develop irrigation infrastructure, such as automated and drip systems.

• Integrated water management through building design

  At Infosys, we ensure design reviews and infrastructure development that take water sustainability into account.We have also installed retrofits in our plumbing systems, such as low-flow fixtures, pressure-compensating aerators, waterless urinals, and sensor-based taps in high-usage areas, enabling us to meet our water conservation goals.

• Re-engineering and retrofit projects

  To conserve fresh water in existing buildings, various measures have been undertaken to minimize water demand. Water distribution and treatment strategies have been enhanced with re-engineering and modifications. This includes upgrading existing plants with high-recovery treatment systems, energy-efficient electromechanical equipment, and automated monitoring of flow and levels, as well as specific water-quality parameters.

• Wastewater recycling

  We remain committed to the long-term goal of zero wastewater discharge and to 100% wastewater recycling across our campuses. All wastewater generated – entirely domestic – is routed to the state-of-the-art Sewage Treatment Plants (STPs), where it undergoes tertiary treatment using advanced membrane bioreactor technology, producing output that meets environmental/legislative requirements. Older plants have been retrofitted to improve recovery, efficiency, and treated water quality. Treated water is then fully reused for secondary applications such as landscaping, flushing, and cooling towers, supported by dual-piping systems and continuous quality monitoring to ensure full compliance with environmental norms. This process significantly reduces our dependence on freshwater sourcing and enhances operational resilience across locations, including leased sites where wastewater is directed to centralized treatment facilities.

• Restore: Replenishing water-stressed ecosystems

  Infosys recognizes that true water stewardship extends beyond our campus boundaries. In regions where groundwater depletion threatens communities, we are investing in large-scale restoration initiatives that actively replenish aquifers and revive degraded water bodies.

• Water Positive Certification

  In continuation of our efforts on achieving water positive / neutral status based on NITI AAYOG guidelines in our campuses. We are water positive at our Bangalore campus and have recently achieved Scope 1 certification at nine of our campuses in India – Chennai Mahindra City, Chennai Sholinganallur, Trivandrum, Mysore, Hyderabad SEZ, Hyderabad STPI, Chandigarh, Bhubaneshwar SEZ, and Bhubaneshwar STPI this year. Scope 1 covers operational efficiency and focuses on direct water resource offsets, considering both quantity and quality and evaluation of site-level water use and impact at the watershed level.
