Reduced height of Yellampalli project causes concern

KARIMNAGAR, OCT. 2. The ambitious Yellampalli project (Sripada Sagar project) on the Godavari at Yellampalli village in Ramagundam mandal of Karimnagar district will be fruitful only if the project is constructed at a height of 148 metres to store 20 tmcft of water.

But, the State Government's decision to construct the project at a height of 143.5 metres to store only 9 tmcft of water is causing concern among the people of the district. Notification issued

Recently, the Government issued notification inviting consultants for preparation of the project report to get all clearances from the Central Water Commission and other departments and construction of project at a height of 143.5 metres.

The Chief Minister, Y.S Rajashekhar Reddy, at the stone-laying function for the Yellampalli project, had assured of measures for constructing the project at a height of 148 metres.

According to official sources, the dependable yield available at Yellampalli barrage site is about 65 tmcft of water of which 60 tmcft can be utilised -- 7 tmcft for NTPC, Ramagundam, and 53 tmcft for drinking and irrigation requirements of the region. "For utilising 60 tmcft of water, 4,600 cusecs water is required for 150 days. In view of SRSP and Kadam projects on the upstream of this scheme, there will not be perennial in flows to the barrage even in rainy season.

The Government has given administrative sanction for the first phase of the Yellampalli project for Rs. 900 crores at a height of 143.5 metres to store 9 tmcs of water.

But there is every possibility of getting silt and thus reducing the live capacity up to 4 tmcft or even less. Even this 4 tmcft will not be sufficient for 10 days.

If the project is constructed at a height of 148 metres to store 20 tmcft of water, even if 8 tmcft of water is lost due to silt, the balance of 12 tmcft of water can be sufficient for 30 days of pumping.

Cost-cutting move

The proposal to integrate the Pranahita river water with Godavari river water at Yellampalli project to irrigate about 20 lakh acres of upland regions of Telangana districts by utilising about 140 tmcft of water, will be most economical in capital cost as well as recurring cost when compared to Devadula lift irrigation scheme, irrigation officials said.

There would not be any problem of submergence, officials said adding that for the construction of project at 143.5 metres, the spill-way vents will be around 108. For the height of 148 metres, the spill-way vents would be 79 saving a huge amount of civil works. The difference amount of Rs. 75 to 80 crores saved through civil works can be distributed towards land acquisition compensation, they suggested.
