New Delhi, Aug 21: The Government of India and the Asian Development Bank (ADB) have signed a $230 million loan agreement to modernise Chennai’s water supply and sanitation infrastructure, strengthening the city’s water security and supporting its long-term, climate-resilient urban development.
The Chennai Climate-Resilient Water Security and Sewerage Project is aimed at improving access to safe, reliable and efficient water and sanitation services while contributing to better public health and quality of life for residents.
The project will support the construction of more than 170 km of new water supply and sewer pipelines and the upgrading of seven water pumping stations and 38 sewer pumping stations. These improvements are expected to strengthen the city’s existing network and improve the delivery of essential services.
A major highlight of the initiative is the planned introduction of a comprehensive ring-main water distribution system. The closed-loop network is designed to maintain more balanced water pressure, improve distribution efficiency and strengthen the reliability of water supplies across service areas. Chennai is set to become the first Indian city to implement such a system at this scale.
The project will also bring greater use of digital technology into water and sanitation management. Real-time monitoring and data-driven systems will support better decision-making, quicker responses to service issues and improved customer services. Advanced technology will also help reduce hazardous manual sewer inspections and enable faster identification of blockages, enhancing worker safety.
The investment is expected to make Chennai’s water infrastructure more prepared to deal with climate-related pressures and natural hazards. At the same time, improved utility management and performance-based contracts will support more efficient and financially sustainable operations.
The initiative is aligned with the Government of India’s urban development priorities, including AMRUT 2.0 and the Urban Challenge Fund, while building on ADB’s previous support for water and urban infrastructure in Chennai.
The agreement was signed by Saurabh Singh, Deputy Secretary in the Department of Economic Affairs, Ministry of Finance, on behalf of the Government of India, and Mio Oka, Country Director of ADB’s India Resident Mission, on behalf of the Asian Development Bank.
The $230 million partnership represents a significant investment in Chennai’s future, combining modern infrastructure, digital innovation and climate-resilient planning. The project is expected to contribute to better water security, stronger sanitation services, healthier communities and a more sustainable urban environment.
With the initiative bringing together international financing and India’s urban development priorities, Chennai is set to take an important step towards building a modern, reliable and resilient water system capable of meeting the needs of its growing population.
