No amount of rejuvenation by any means can perpetuate the 114 year old deteriorated Mullaperiyar dam. Ageing is a nonretrievable process in the case of water retaining structures also, as is the case with living objects. Mullaperiyar dam began to age sending a series of warning signals about its diminishing strength and capacity. There is a limit to the number of years one can keep dams in service through maintenance and strengthening measures. All over the world, citizens, Governments and organizations have begun to review the safety of their dams as per modern standards and design criteria. Hundreds of dams have already been dismantled or decommissioned in an attempt to allay the fears of the people living downstream and to ensure safety to their lives and properties.

Rebuilding of a new dam below the old Victoria dam in Australia in 1981, when the old dam was found unsafe as per modern safety requirements is one of the many examples.
