Edited sentence: A recent law, promulgated by the Kerala government against increasing the storage level has not been objected to by the Supreme Court of India, which  termed it as not unconstitutional.But so far Kerala has not objected in giving water to Tamilnadu.Increasing the level would add more pressure to be handled by already leaking dam.Obviously no masonry dam will survive for 999 years so a new dam may replace the existing one in near future.Their main cause of objection is the dams safety as it is as old as 110 years
