Chennai: The Confederation of Indian Industry’s Indian Green Building Council (CII-IGBC) has launched a report on nature-based wastewater treatment solutions for Tamil Nadu, highlighting sustainable approaches to wastewater management, water reuse and environmental protection.
The report, Nature-Based Solutions for Treating Wastewater in Tamil Nadu, was unveiled at a conference on October 22, 2026, at ITC Grand Chola, Chennai.
The event brought together government officials, industry experts, researchers and sustainability professionals to explore decentralised, nature-inspired treatment systems.
Thiru Simranjeet Singh Kahlon, IAS, Managing Director of Chennai Rivers Transformation Company Limited (CRTCL), and Thiru Bakan Jagdish Sudhakar, IFS, CEO of Tamil Nadu Green Climate Company, launched the report.
Kahlon stressed the need to address gaps in sewage collection and treatment across urban and rural local bodies. He said nature-based solutions could support decentralised wastewater treatment, while larger urban areas require systems suited to high and fluctuating wastewater volumes. He also highlighted their role in river restoration and urban waterbody conservation.
Sudhakar said nature-based approaches could strengthen climate-resilient infrastructure and support ecosystem restoration. He noted that such wastewater treatment solutions were already being implemented in schools across Greater Chennai and called for wider adoption through collaboration.
Mahesh Anand, Chairman of the IGBC Chennai Chapter, said the state had 1,520 IGBC-registered projects covering approximately 1.02 billion sq. ft.
He said the report and guidebook would help urban local bodies, engineers and planners adopt suitable treatment technologies and safe water reuse practices. A panel discussion examined challenges in scaling these solutions across cities and communities.
Technical presentations showcased innovative treatment systems and decentralised approaches for sustainable communities.
The initiative aims to encourage locally adaptable wastewater solutions, improve water resource efficiency and strengthen collaboration among government, industry and technical institutions.
