Fast Summary
- the Polavaram project Authority (PPA) has stated that Andhra Pradesh’s proposal to divert 200 tmc ft of water under the Polavaram-Banakacherla Link Project (PBLP) can only be considered after the completion of Polavaram up to its full reservoir level (FRL) of 45.72 meters.
- Phase-I of the Polavaram project plans to store water at a level of 41.15 meters, with a revised cost approved by the Union Cabinet in August 2024 at ₹30,437 crore. Operational constraints have impeded full realization of benefits in Phase-I.
- the diversion proposal is not part of Polavaram’s approved detailed project report (DPR).
- Polavaram seeks utilization of 449.78 tmc ft Godavari water for irrigation, stabilizing existing ayacut, supplying domestic and industrial needs, and providing interstate allocations to Odisha and Chhattisgarh.
- Right Main Canal and Left Main Canal were planned with capacities of 11,654 cusecs and 8,123 cusecs respectively but are being executed with higher capacities (17,560 cusecs each).The Center reimburses expenditure only as per approved DPR capacities.
- For further linkages like Tadipudi canal integration into PBLP-serving an ayacut area spanning over 83,607 hectares-a complete feasibility study on required capacity upgrades is essential before obtaining approvals.
Indian Opinion Analysis
The development around Andhra Pradesh’s request highlights critical challenges involved in large-scale infrastructure projects related to inter-state river management. While the proposed diversion under PBLP could enhance irrigation and drinking water supply systems across regions if implemented successfully after comprehensive studies, fulfilling operational conditions for Phase-II depends on addressing existing constraints within current frameworks. Additionally, interstate considerations involving Odisha and Chhattisgarh demand adherence to tribunal decisions for equitable resource distribution among all stakeholders.
Such projects underline the need for thorough planning based on dependable data while balancing state priorities against national interests surrounding shared freshwater resources amidst increasing demand pressures across competing sectors like agriculture and industry.
