Water & Waste sustainability summit 2026 accelerated circular economy solutions in Chennai

Policymakers, industry leaders, sustainability experts, academicians and technology innovators convened at Hall No. 4, New Halls, Chennai Trade Centre for the Water & Waste Sustainability Summit 2026: Driving Circular Economy Solutions, organized by PHD Chamber of Commerce and Industry (PHDCCI) and Water Today. The high-impact summit aimed to advance water stewardship, waste management reforms and circular economy implementation across India at a time when climate variability, rapid urbanisation and industrial growth were intensifying pressure on natural resources.

The summit focused on translating sustainability commitments into scalable, measurable action. Deliberations centred on policy alignment, innovative technologies, climate finance and collaborative frameworks that could enable industries and urban systems to transition toward resource efficiency, zero-waste models and sustainable water use.

The summit was virtually inaugurated by Shri Sumant Narain, Joint Secretary (National Water Mission), Ministry of Jal Shakti, Government of India, who delivered the keynote address outlining national priorities for integrated water resource management and conservation. The National Water Mission, under the National Action Plan on Climate Change, had set a clear target of achieving a 20 per cent improvement in water-use efficiency across sectors. The mission was being implemented through regulatory reforms, water budgeting, data-driven monitoring and inter-sectoral convergence.

Government initiatives such as Jal Jeevan Mission, AMRUT 2.0 and Atal Bhujal Yojana reflected a strategic shift from supply augmentation to demand management, reuse and efficiency. A key policy priority was the mainstreaming of treated wastewater reuse in urban and industrial planning, integrating reuse mandates into contracts, by-laws and industrial approvals. Water audits, metering and disclosure mechanisms were expected to increasingly form part of compliance and ESG reporting frameworks.

To translate this commitment into measurable action, the Chamber announced that it would conduct a minimum of 50 training workshops and webinars, develop sector-specific operational toolkits, establish a centralized digital platform for sharing best practices, and implement annual water-use efficiency assessments aligned with transparent benchmarking and sustainability reporting frameworks.

The inaugural ceremony also featured opening remarks by Ms. Ramya Narayan, Editor of Water Today Magazine, who stated that the summit aimed to catalyse actionable solutions that moved beyond dialogue to implementation. The summit was expected to generate strategic partnerships, promote investment in sustainable infrastructure, and reinforce India’s commitment to climate resilience and circular resource management.
