  • It is aimed at solving the drinking water problems of Bengaluru.
  • This project was also touted as one that could generate hydroelectricity to meet the power demand in the state.


Why does Tamil Nadu object?

  1. The state contended that “the proposed reservoir would affect the natural flows of the river Cauvery.
  2. It argued that Cauvery was already a deficit basin and the construction of the project, or any other project “would drastically affect the lower riparian State in getting their due share of waters.
  3. The total annual quantum prescribed by the Supreme Court for Tamil Nadu is 177.25 thousand million cubic feet (tmc ft) in a year. Of this, 80 tmc ft is estimated to be coming from the “uncontrolled catchments” below Kabini and KRS. The Mekedatu project will interfere with the flow of this portion of the State’s due.
