The Asian Development Bank (ADB) has approved a $200 million loan to develop climate- and disaster-resilient sewerage and drainage infrastructure in Kolkata, aiming to enhance urban livability and reduce flood risks.
The investment is part of the Kolkata Municipal Corporation Sustainability, Hygiene, and Resilience (Sector) Project, which seeks to improve public health and living conditions, particularly for vulnerable groups such as women and children, ADB said in a statement.
Kolkata, one of India’s most densely populated cities, struggles with inadequate drainage and sewerage systems, leading to urban flooding and unsanitary conditions. These challenges are worsening due to the increasing frequency of heavy rainfall linked to climate change, ADB noted.
To address these issues, the project will include the construction of 84 kilometers of trunk and secondary sewerage and drainage pipelines, 176 kilometers of lateral pipelines extending to customer connections, and 50,000 new household sewer connections. Additionally, it will establish a new sewage treatment plant and five pumping stations.
Once completed, the initiative is expected to benefit over 277,000 residents, significantly improving sanitation and flood resilience in the city.
