This project is part of the Kolkata Municipal Corporation Sustainability, Hygiene, and Resilience (Sector) Project, which seeks to improve sanitation, urban flood management, and overall public health outcomes. Kolkata, one of India’s most densely populated cities, struggles with inadequate drainage and sewerage systems, leading to frequent urban flooding and unhygienic conditions—issues that are worsening due to climate change-driven heavy rainfall.

To address these concerns, the project will construct 84 km of combined trunk and secondary sewerage and drainage pipelines, along with 176 km of combined lateral sewerage and drainage pipelines reaching customer connections. Additionally, 50,000 new household sewer connections will be established, significantly enhancing the city’s sanitation network. The plan also includes the construction of one sewage treatment plant and five pumping stations, benefiting over 277,000 residents.

Industry and Market Outlook India’s urban infrastructure sector is witnessing increased investments in sustainable and climate-resilient projects, driven by rapid urbanisation and climate change adaptation needs. ADB’s continued financial support underscores the growing emphasis on integrated urban planning, resilient infrastructure, and environmental sustainability. As cities like Kolkata modernise their sewerage and drainage systems, the demand for advanced water management technologies, green engineering solutions, and public-private partnerships is expected to rise, fostering a more sustainable urban future.
