The largest river linking project in India has seen its estimated cost rise by more than 60 billion (bn) before construction has begun, according to officials. The revision reflects an increase to earlier budgetary estimates as planners prepare to finalise contracts and mobilise resources. The rise comes while preliminary approvals remain under completion and procurement is being planned. Officials noted that the revision factors in updated design standards and general inflationary pressures, which were not fully accounted for in earlier estimates.

Officials attributed the increase to a combination of higher input costs, delays in land acquisition and extended timelines for environmental clearances. Compensation and rehabilitation estimates were revised upwards and logistics and material prices added to the fiscal burden. Project managers indicated that contingency provisions had been exhausted in preliminary budgeting. Revised estimates also reflect extended stakeholder consultations and the complexity of resettlement planning that has emerged during preparatory work.

The upward revision is likely to prompt fresh funding discussions between central and state authorities and may require supplementary allocations in coming budgets. Lenders and contractors are expected to seek clarity on cost-sharing arrangements and revised schedules. Analysts warned that prolonged uncertainty could increase overall expenditure further and affect project delivery. Observers expect parliamentary and audit scrutiny to intensify until a clear financing plan and revised delivery schedule are presented.

Officials said reviews and technical audits would be undertaken to rework timelines and cost controls, and procurement procedures would be revisited to improve outcomes. If completed as envisaged, the linkage is intended to enhance irrigation and water availability in deficit regions and support broader economic objectives. The outcome will depend on efficient management of resources and timely resolution of regulatory and land issues. Authorities plan to engage with stakeholders and consider phased implementation to contain costs while aiming to preserve the long term objectives of the linkage.
