Probe ordered into inundation
Floodwater from the dam was let into the upstream intake and downstream DT areas
Hyderabad: Telangana State Power Generation Corporation (TSGenco) chairman-cum-managing director Devulapally Prabhakara Rao ordered a high-level inquiry into the inundation of the Lower Jurala Hydel Power Station units under construction
Mr Rao said that units 1, 2 and 3 were planned to be synchronised in August and all necessary measures had been tak-en to facilitate water filling of upstream intake and downstream TRC.
On Wednesday, floodwater from the dam was let into the upstream intake and downstream DT areas at around 6 pm.
After attaining an elevation of 297 metres on the upstream side at about 9 pm, TSGenco engineers and the contractor inspected for leakages. During the inspection, the leakages were found to be very negligible. But at about 10.05 pm, a sudden gush of water was observed through the upstream gates of Unit No. 4.
Immediately after forecasting the danger of inundation of the Power House, all necessary evacuation measures were taken on a war footing and human loss was avoided. The downstream DT gate of
Unit No. 4 was opened to avoid complete inundation of the Power House.
The electrical control panels in the power house were also saved from inundation.
The extent of damage to the power house would be known only after carrying out dewatering of Intake and power house areas, said Mr Rao.
The formation of earthen bund on the upstream side has been taken up immediately and the dewatering will be taken up after completing the same. The earthen bund and dewatering are expected to be completed in about five to six days, he added.
