The Asian Development Bank (ADB) has sanctioned a $200 million loan to support the development of climate- and disaster-resilient sewerage and drainage infrastructure in Kolkata. This initiative, part of the Kolkata Municipal Corporation Sustainability, Hygiene, and Resilience (Sector) Project, aims to enhance the city's livability while addressing flood risks and improving sanitation.

Kolkata, one of India's most densely populated cities, struggles with inadequate drainage and sewerage systems, leading to frequent urban flooding and unsanitary conditions. The situation has worsened due to increasing heavy rainfall linked to climate change. To mitigate these challenges, the project includes the construction of 84 kilometres of combined trunk and secondary sewerage and drainage pipelines, along with 176 kilometres of lateral pipelines extending to customer connections. Additionally, 50,000 household sewer connections will be installed. The initiative will also establish a new sewage treatment plant and five pumping stations, benefiting over 277,000 residents.

Beyond infrastructure development, the project focuses on strengthening the Kolkata Municipal Corporation's operational capacity. It includes the implementation of an IT-based asset management system and measures to enhance property tax revenue collection. The city's early flood warning system, introduced in a previous ADB initiative, will be expanded to improve disaster preparedness. Furthermore, efforts will be made to raise community awareness about water, sanitation, and hygiene, alongside programs to support women's employment through skills training and internships.

ADB, a key multilateral development bank, plays a crucial role in fostering sustainable and resilient growth across Asia and the Pacific. Established in 1966 and comprising 69 member countries, it leverages financial resources and strategic partnerships to address complex development challenges and improve infrastructure.
