Hyderabad: The rejuvenation of Krishna river, an initiative by the India Water Council (IWC), should start with routing of the Koyna water back to the basin, said V Prakash, Chairman, Telangana Water Resources Development Corporation, on Thursday.
As a member of the IWC, he visited the Koyna dam and its hydel units to take stock of the diversion of the Koyna waters beyond the basin.
The IWC members, at the national meet on Krishna rejuvenation held here recently, voiced concern over use of over 100 TMC of water of Koyna only for power generation at the hydel unit before it was let off to the Arabian Sea.
The Koyna project chief engineer and senior officials explained him about the use of water for power generation in different stages by showing tunnels, penstocks, generators and underground substations put up with France technology.
Koyna’s four phases had the capacity to generate 1956 MW before the water is diverted from Krishna basin to Arabian Sea. He said if Maharashtra decides to generate 1956 MW with 100% PLF, even 400 TMC of water also would be insufficient for the project.
If Maharashtra gives Koyna water to lower basin States, they can give power in return, he added. Rainfall in Koyna basin is 4,000 to 6,000 mm.
He also visited Ralegansiddhi and met Anna Hazare.
