The top court had modified the Cauvery Water Disputes Tribunal (CWDT) award of 2007. It had raised the 270 tmcft share of Cauvery water for Karnataka by 14.75 tmcft and reduced Tamil Nadu’s share, while compensating it by allowing extraction of 10 tmcft groundwater from the river basin, saying the issue of drinking water has to be placed on a “higher pedestal”
