The Karnataka government will submit a revised Detailed Project Report (DPR) to the Centre for the Mekedatu balancing reservoir across the Cauvery river.
The Supreme Court termed Tamil Nadu's challenge to the project as "premature," potentially allowing the Cauvery Water Management Authority (CWMA) and Central Water Commission (CWC) to review Karnataka's proposal.
The Mekedatu project, estimated at ₹9,000 crore, aims to impound 67.16 TMC of water and generate 400 MW of hydropower.
Bengaluru faces a water shortage of 500 MLD, with demand projected to reach 4,000 MLD by the time the city's population hits 20 million.
Detailed Insights:
The Mekedatu project involves constructing a reservoir near Mekedatu, about 100 km from Bengaluru, submerging approximately 4,996 hectares of land, including forest and wildlife areas.
Karnataka aims to utilize an additional 4.75 TMC of water allocated by the Supreme Court in its 2018 judgment to address Bengaluru's growing drinking water needs.
Tamil Nadu fears that the project could lead to excessive water storage by Karnataka, affecting water release to the lower riparian state, especially during critical periods.
Alternatives to the project include rainwater harvesting, which could yield about 15 TMC annually, and reuse of treated wastewater, potentially providing about 16 TMC annually for Bengaluru.
The Union Ministry of Environment, Forest and Climate Change's Expert Appraisal Committee emphasized the need for an "amicable solution" between Karnataka and Tamil Nadu due to inter-State issues.
Key Concepts Involved:
Detailed Project Report (DPR): A comprehensive document outlining the plan, cost, and impact of a proposed project.
Cauvery Water Management Authority (CWMA): An authority constituted to implement the Cauvery Water Disputes Tribunal's award and manage the river's water resources.
Inter-State River Dispute: Disagreements between states over the allocation and usage of water from rivers that flow through multiple states.
