GANDIKOTA LIFT IRRIGATION SCHEME

Preamble

GKLI Scheme is proposed to lift 6.00TMC of water from foreshore of Gandikota Reservoir through 2 stages of lifts

1) From Gandikota Reservoir to Paidipalem Reservoir.

2) From Himakuntla sump to PBC with a feeder channel from Paidipalem Reservoir to Himakuntla sump to irrigate gap ayacut of 41,000 acres under PBC and direct ayacut of 47,500 acres in 6 mandals.
