Tamil Nadu has rights both on legal and humanitarian grounds to implement the second phase of the Hogenakkal Drinking Water Project, Water Resources Minister Duraimurugan said here on Saturday. Responding to his Karnataka counterpart Govind Karjol, Duraimurugan cited several aspects of the final award of the Cauvery Water Dispute Tribunal including clause-18 and consumptive use and the Supreme Court judgment of February 16, 2018 to underscore that Tamil Nadu has rights to execute this project, which is essential for drinking water needs.
