India, ADB sign $230 million loan to upgrade Chennai water supply system

• The Union government and the Asian Development Bank (ADB) signed a $230 million loan to modernise and expand Chennai’s water supply and sanitation infrastructure.

Highlights of the project:

• The Chennai Climate-Resilient Water Security and Sewerage Project will improve access to safe and reliable water supply and better sanitation services across Chennai. 

• ADB’s latest investment builds on earlier projects in the city to expand access to safe and equitable water and waste management services, in line with the Government of India’s flagship urban development interventions, such as the Atal Mission for Rejuvenation and Urban Transformation 2.0 and the Urban Challenge Fund.

• The project will construct over 170 kilometers of water supply pipes and sewer pipes, upgrade seven water pumping stations and 38 sewer pumping stations, and strengthen water utility assets and operations management through performance-based contracts. 

• Chennai will become the first Indian city to implement a comprehensive ring-main solution. 

• It is a closed-loop system designed to maintain balanced water pressure and deliver water efficiently across service areas, improving reliability, equity, and resilience to natural hazards in its urban water supply system.

Asian Development Bank

• The Asian Development Bank (ADB) envisions a prosperous, inclusive, resilient, and sustainable Asia and the Pacific, while sustaining its efforts to eradicate extreme poverty in the region.

• From 31 members at its establishment in 1966, ADB has grown to encompass 69 members — of which 50 are from within Asia and the Pacific and 19 outside.

• ADB assists its members, and partners, by providing loans, technical assistance, grants, and equity investments to promote social and economic development.

• ADB maximises the development impact of its assistance by facilitating policy dialogues, providing advisory services, and mobilising financial resources through co-financing operations that tap official, commercial, and export credit sources.

• Committed to pursue a differentiated approach for states at different stages of development, ADB prioritises projects on basic services, critical infrastructure and services, institutional strength, and private sector development through sovereign operations in low-income states.

• Support for more developed states focuses on transformational programmes with policy and knowledge advice, combined with non-sovereign operations.

History of ADB

• ADB was conceived in the early 1960s as a financial institution that would be Asian in character and foster economic growth and cooperation in one of the poorest regions in the world.

• A resolution passed at the first Ministerial Conference on Asian Economic Cooperation held by the United Nations Economic Commission for Asia and the Far East in 1963 set that vision on the way to becoming reality.

• The Philippines capital of Manila was chosen to host the new institution, which opened on December 19, 1966, with 31 members that came together to serve a predominantly agricultural region. Takeshi Watanabe from Japan was ADB’s first president.

ADB and India

• India was a founding member of ADB in 1966 and fourth largest shareholder.

• ADB started operations in India in 1986.

• India is among the largest recipients of public sector support from ADB.

• As of July 2026, ADB has committed 683 public sector loans, grants, and technical assistance totaling $63.8 billion to India.
