In what could ease the water woes of the city, the Brihanmumbai Municipal Corporation (BMC) is considering increasing the height of the Tansa dam by one foot. This would increase the storage capacity of the damn by approximately 13,500 million litre – which is a month’s additional supply of water from the dam to the city.
Currently, the Tansa dam contributes 455 million litre of water a day, of the total 3,3550 million-litre daily supply of water to the city.
Former deputy municipal commissioner PR Sanglikar had mooted a similar proposal in September 2008, in the wake of the water crisis, the proposal was not considered seriously.
Standing committee chairman Rahul Shewale has put the fresh proposal forth. "I am putting this proposal before the civic administration, for the height of the dam to be increased," he said.
"The dam currently stores 1.80 lakh million litre of water. After the height is increased, it will be able to accommodate additional 13,500 million litres," said a senior official from the water department.
Rajiv Jalota, additional municipal commissioner, said that the proposal would be considered and reviewed. "As it is old dam, we have to consider about its capacity to handle load, and also the surrounding area that is submerged" The dam has constructed in 1892, over 115 years ago, oldest in the country.
However, Shewale said that as the dam had been strengthened around five years ago, its age should not cause an issue. "There will not be any problem for it to bear the additional load," he said.
