The Bihar government has embarked on a significant initiative aimed at enhancing irrigation management and flood control within the state. Recently, the cabinet approved a substantial project worth ₹4,415 crore focused on water security and the modernization of irrigation systems.

Under the leadership of Chief Minister Nitish Kumar, the state cabinet endorsed the Water Resources Department's proposal for the 'Bihar Water Security and Irrigation Modernization Project' (BWSIMP), which is supported by the World Bank.

This project is designed to improve irrigation efficiency, bolster institutional capacity, and enhance flood risk management. It aims to prepare the state for disaster and emergency situations through effective capacity building.

The initiative prioritizes districts that are frequently impacted by floods, waterlogging, and drought. It aims to manage excess water flow from major rivers to reduce flood risks. Key measures include modernizing dams and restoring irrigation capabilities in drought-stricken areas.

The project is primarily funded externally, with an estimated cost of ₹4,415 crore. The Bihar government will contribute 30% (₹1,324.50 crore), while the remaining 70% (₹3,090.50 crore) will be financed through a loan from the World Bank.

The project comprises four main components, allocating ₹2,487 crore for climate-resilient irrigation, ₹1,525 crore for flood risk reduction, ₹243 crore for water governance, and ₹160 crore for project management.

The project includes the modernization of essential irrigation systems to lessen reliance on rainfall, ensuring farmers have access to irrigation even during adverse weather conditions.

Key initiatives involve rehabilitating the Son, Gandak, and Kosi barrages, modernizing the Son Western Main Canal, and upgrading the Western Kosi irrigation systems, along with the Jhanjharpur Branch Canal and the Saran Main Canal.

Additionally, the project focuses on rehabilitating and strengthening embankments and spurs identified for flood risk mitigation. Advanced design technologies will be employed in collaboration with World Bank consultants.

Key initiatives include elevating and reinforcing the left embankment of the Bagmati River, conducting anti-erosion work in the Katihar district, and renovating various spurs of the Eastern Kosi embankment.
