Transition period of 10 years was permitted in which India was bound to supply water to Pakistan from its eastern rivers until Pakistan was able to build the canal system for utilization of waters of the western rivers. Per Article 5.1 of IWT, India agreed to make fixed contribution of UK Pound Sterling 62,060,000/= (Pound Sterling sixty two million and sixty thousand only or 125 metric tons of gold when gold standard was followed) towards the cost of construction of new head-works and canal system for irrigation from western rivers in Punjab province of Pakistan. India had paid the total amount in ten equal annual installments despite the 1965 Indo-Pak war.
