During tunnel excavation of the 2nd Bench Connecting Tunnel, a weak rock mass collapsed, causing water from the Intake Pit to enter the Tunnel and the Power House area.

All workers were immediately evacuated safely.

The water from the Intake Pit has been completely drained and no further water is entering the downstream work sites. Dewatering from under construction power house has started.

Senior WAPDA Officers, the Engineer and Contractor are currently assessing the situation to cater for any challenge to the Project T-5 . The information in circulation about collapsing of the T -5 Tunnel is incorrect . There is no damage to main Tunnel, under construction power house , tailrace culvert or switch yard . Moreover, there has been no injury or loss of life to the work force.
