The refurbishment will avoid potential sources of failure and extend the structure’s life to another 50 years.

It is being carried out under Sindh Barrages Improvement Project (SBIP), which will support the gate replacement works to enhance the regulation and the flow of the barrage.

Under the project, 65 main barrage steel gates, 25 main canal head regulator gates, and hoist gears including all mechanical and electrical equipment will be replaced.

More than 2.6 million people across three million acres of irrigated land in Kashmore, Ghotki, Jacobabad, Sukkur, and Shikarpur districts of Sindh, and Nasirabad and Jafarabad districts of Balochistan will receive reliable supply of water.

It will improve flood management and reduce risks of embankment breaches.

World Bank Country Director for Pakistan Rachid Benmessaoud said: "In addition to physical rehabilitation of barrage infrastructure, this project will also support the Sindh Government in training and technical assistance in procurement, financial, social and environmental safeguards for operating hydraulic irrigation infrastructure."

The World Bank’s loan will have a maturity of 25 years, including a 5-year grace period.
