Infosys Collaborates with Siruthuli for the Rejuvenation of Thangal Lake in Chennai
Infosys, in collaboration with Siruthuli, a not-for-profit organization focused on environmental conservation and water body restoration, inaugurated the rejuvenated Thangal Lake in Sholinganallur, Chennai. The inauguration was attended by Shri. ECR.P. Saravanan, Member of the Legislative Assembly, Sholinganallur Constituency, Shri. Aftab Rasool, IAS, Regional Deputy Commissioner (South), Greater Chennai Corporation, Mr. Anil Kumar P.N., Senior Vice President and Center Head, Chennai, Infosys, and Mr. Niladri Prasad Mishra, Senior Vice President and Head of Global Infrastructure, Infosys, along with other dignitaries.
The rejuvenation of Thangal Lake reflects Infosys’ ongoing efforts to support environmental sustainability through ecosystem restoration initiatives that enhance water security, strengthen biodiversity, and create lasting value for local communities.
Supported through a CSR grant of over INR 5 crore, the project has transformed Thangal Lake into a more resilient urban ecosystem. The rejuvenation has nearly doubled the lake’s storage capacity, from approximately 150 million liters to nearly 300 million liters, enhancing its ability to retain water, improve flood resilience, and support groundwater recharge. By addressing water pollution, flooding risks, and habitat degradation, the initiative demonstrates the role of nature-based solutions in strengthening urban sustainability.
The restoration involved a range of ecological interventions, including deweeding, desilting, bund strengthening, sewage diversion, lagoon and island development, creation of floating wetlands, plantation, and fencing. These measures have helped improve water quality, restore ecological balance, and enhance the overall health of the lake ecosystem.
The project also focused on strengthening biodiversity through the creation of bird habitats, introduction of fruit-bearing trees, implementation of erosion-control measures, and deployment of natural treatment solutions. Together, these interventions are helping create a healthier environment for a variety of plant and animal species.
In addition to its ecological benefits, the rejuvenated lake has been developed as a community space. Walking pathways, seating areas, a children’s play area, an outdoor gym, and solar-powered lighting have improved accessibility and encouraged greater community engagement with the restored water body.
