Project Objectives:
Sustainable irrigation supplies to about three million acres of fertile land of seven districts of Punjab;
Ensured safe passage of floods due to enhancement of design capacity of the new barrage; and
Provision of communication link across the river
Project Cost: Project was executed with the financial assistance of the ADB (SDR 143.729 million = USD 270 million) while counterpart fund provided by the Punjab government (USD 39 million).
Problems:
Aging effect;
Capacity constraint;
Lack of effective control on river regulation;
Inefficient and insufficient physical communication between the two banks of the Chenab River;
Mixture of several design & construction techniques.
Project Components:
A new modern barrage, 900 ft downstream of existing weir and incorporating an AR Bridge
New head regulator of L.C.C;
Re-aligned head reach of L.C.C originating from new head regulator and joining existing LCC at RD 5
Improvement of roads on both river banks, buildings and other infrastructure.
Rehabilitation of River Training works
Status:
