Water Resources Management in the Pyanj River Basin Project (Second Additional Financing): Report and Recommendation of the President

The grant will contribute to financing the cost overrun of the original project for the construction of a sediment excluding basin (SEB). This is a key infrastructure component for achieving the project’s outcome and for optimizing project costs. The SEB will ensure that the water quality in the Chubek Irrigation System (CIS) is suitable for agricultural production. It will optimize operation and maintenance (O&M) costs of the CIS in the long-term by reducing sediment inflow. The cost overrun was identified during detailed technical surveys and structural design under the original project. Actual site conditions were inconsistent with the assumptions applied for the feasibility-level design of the SEB prepared during project preparation. The technical design of the SEB requires substantial revision to achieve its anticipated sediment-removing function. This will result in a cost overrun.

The report and recommendation of the President to the Board of Directors (RRP) document describes the terms and conditions of a project for consideration and approval by ADB's Board of Directors.
