| MULLAPERIYAR DAM |
- JOIN HANDS FOR NEW DAM ,SAVE 35 LAKH PEOPLE IN KERALA
Mullaperiyar dam is 116 years old as of 2011. It has outlived its expected life span of 50 years.Strengthening the existing dam has its limitations and may not prove to be effective in the event of a disaster (reference: Morvi Dam)
- Construction Material: The dam was constructed using lime & surki mixture (consisiting of sugar &calcium oxide). Seepage and leaks from the dam have caused concern
- Earthquakes: The dam is situated in a seismically active zone . CESS has reported that the dam cannot withstand earthquakes above 6 point on the Richter scale. An earthquake measuring 4.5 on the Richter scale occurred on June 7, 1988 with maximum damage in Nedumkandam and Kallar (within 20 kms of the dam). Several earthquake tremors have occurred in the area in recent times. These could be reservoir-induced seismicity, requiring further studies according to experts.
- Changing weather patterns leading to incessant rains, flooding and overflow of the dam.
- Inadequate safety maintenance and safety monitoring of the dam
The Idukki Hydroelectric project, located 30 km downstream was completed in 1976 by the Kerala government After Independence the areas downstream of the Mullaperiyar become heavily inhabited, as Kerala has a very high population.If Mullaperiyar dam- breks idukki dam can,t withstand leading to huge disaster.
Presently mulaperiyar dam contain 11.75 T.M.C water .Idukki has a capacity to retain 74 T.M.C water ,dam presently has almost 65 T.MC water.Logically not possible to store powerful water rush at 18000 joules power (10 times stonger than atom bomb bursted at Hiroshima ) - SAFETY FOR KERALA , WATER FOR TAMIL NADU
