Deputy chief minister Ajit Pawar’s proposal to seek 10 TMC water from Tata Dam for the district may not materialise because it would affect the areas under Mumbai and Konkan divisions, stressed senior officials of the irrigation department.
The diversion of water would affect the hydropower generation and lead to violation of the Krishna Water Dispute Tribunal norms, set for Maharashtra and three neighbouring states — Karnataka, Andhra Pradesh and Telangana — on the water allocation from the Krishna river basin, the officials claimed.
The Tata Dam gets 42.5 TMC water from Mulshi, Shirwata, Walvhan, Lonavala, Thokarwadi and Kundli to feed three power houses — Bhira, Khopoli and Bhivpuri — for generating 447MW electricity for the Mumbai region.
After the Pune municipal commissioner sought allocation of a separate dam to meet the city’s water needs, the deputy chief minister had said on Monday there was no space to construct any new dams. He also said he would request Tata Dam to divert water for the city and rural areas in the district, as was done earlier in 2015.
The irrigation department officials stressed that the diversion of water from Tata Dam would not be in the interest of the state in view of the tribunal restrictions and the technical importance of hydropower generation. “The diversion of 10 TMC water will mean non-availability of peak power to the commercial capital of India,” said an official.
The Krishna Water Dispute Tribunal distributed the water available in Krishna Basin between Maharashtra, Karnataka, Andhra Pradesh and Telengana. Maharashtra’s share is 25%. Tata and Koyna were then allowed to divert the east-flowing water to the west side for power generation.
“If any water is made available to Bhima basin from Tata Dam, the other states will claim their rights on it,” he said.
