Why in News

The Karnataka government is likely to pressurise the Centre for approval of the construction of the Mekedatu Project on the Cauvery river.

  • Mekedatu, meaning goat’s leap, is a deep gorge situated at the confluence of the rivers Cauvery and its tributary Arkavathi.
  • Ontigondlu is the proposed reservoir site, situated at Ramanagara district in Karnataka about 100 km away from Bengaluru. It is the midst of the Cauvery Wildlife Sanctuary.
  • The Rs. 9,000 crore project aims to store and supply water for drinking purposes for the Bengaluru city. Around 400 megawatts (MW) of power is also proposed to be generated through the project.

Key Points

  • The project was first approved by the Karnataka state government in 2017.
  • It received approval from the erstwhile Ministry of Water Resources for the detailed project report and is awaiting approval from the Ministry of Environment, Forest and Climate Change (MoEFCC).
    • The approval from MoEFCC is crucial because 63% of the forest area of the Cauvery Wildlife Sanctuary will be submerged.
    • 5,051 hectares of forests would be submerged, including 3,181 hectares in the sanctuary and 1,870 hectares in the reserve forest.
  • 4.75 thousand million cubic feet of water could be drawn from the reservoir to partially meet the drinking needs of Bengaluru.
  • Tamil Nadu has approached the Supreme Court (SC) against the project even if Karnataka has held that it would not affect the flow of water to Tamil Nadu.
  • Reasons for Opposition by Tamil Nadu:
    • Tamil Nadu is opposed to any project being proposed in the upper riparian unless it was approved by the Supreme Court.
    • Karnataka has no right to construct any reservoir on an inter-state river without the consent of the lower riparian state i.e. Tamil Nadu in this case.
      • The project is against the final order of the Cauvery Water Disputes Tribunal (CWDT) in which the SC held that no state can claim exclusive ownership or assert rights to deprive other states of the waters of inter-state rivers.
    • The CWDT and the SC have found that the existing storage facilities available in the Cauvery basin were adequate for storing and distributing water so Karnataka’s proposal is ex-facie (on the face of it) untenable and should be rejected outright.
    • It has also held that the reservoir is not just for drinking water alone, but to increase the extent of irrigation, which is in clear violation of the Cauvery Water Disputes Award.
