MULLAPERIYAR ISSUE
HISTORY
Mullaperiyar dam is a masonry gravity dam on the Periyar River in the Kerala state of India.The Mullaperiyar Dam is a gravity dam made with concrete prepared from limestone and "surkhi" (burnt brick powder), and faced with rubble.Gravity dams use their weight and the force of gravity to support the reservoir and remain stable.The Periyar National Park in Thekkady is located around the dam's reservoir.
Who benefited from the dam?
The dam is located in Kerala on the river Periyar.but the dam is controlled and operated under a period lease by neighboring Tamil Nadu state.Apart from providing drinking water to the people of Madurai, Theni, Sivaganga and Ramanathapuram.
what is the problem now?
The dam is one of the oldest dam in service in the world, at 105 years. The average life-span of a well-built and well-designed dam is considered to be 50-60 years by experts. When the British built the dam, they expected its life span to be around 2,000 years.The Mullaperiyar Dam was made using old technology, and not based on the modern parameters for design of dams. In this case, much of the building material used in the construction has been leached out, by wear and tear.But then again, in 1930s, Tamil Nadu engineers bored 80 holes in the dam and injected 40 tonne of cement solution to plug seepage. Again in 1933, grouting technology was used to strengthen the dam. In 1960, 502 tonne of cement solution was injected. All this was done without any outside prodding.
