Kerala Chief Minister Oommen Chandy and Opposition Leader in state assembly V S Achuthanandan jointly met the PM here and submitted a memorandum stressing their concerns over the dam's safety.
They urged Modi to get Tamil Nadu to agree for construction of a new dam, which will continue to meet its water demand, while at the same time will not be endangering the lives and properties of the people of Kerala.
Kerala also sought the Centre to impress upon the Chairman of the Supervisory Committee and CWC to ensure a fair hearing and treatment for Kerala's concerns.
"The Chairman may ensure that Tamil Nadu should not build up storage above 136 ft when if any one of the 13 spillway gates is not functional and to review the operational efficiency of the 13 spillway gates and the capacity of the generator power to operate these gates in the event of an emergency - something which the committee has not done due to the objections of Tamil Nadu," the memorandum added.
The Ministry of Water Resources had issued the order in the wake of a Supreme Court order on May 7 last year, which had allowed Tamil Nadu to raise the water level to 142 feet and ultimately to 152 feet after completion of strengthening measures on the dam.
