On Monday, the protective bund of the Tarbela Dam 5th Extension Project's Tunnel-5 tunnel collapsed, leading to a sudden water surge, officials informed the news agency Dawn. The Water and Power Development Authority (Wapda) issued an emergency declaration, halting construction activities and instructing workers to relocate to safer zones.
Wapda explained that the incident occurred due to a weak rock mass collapse during excavation work, causing water from the Intake Pit to enter the under-construction power house area and a tunnel of the Tarbela Dam 5th Extension Project. All workers were swiftly evacuated, and Wapda announced that the water from the Intake Pit had been completely drained, with no further water entering the downstream work sites.
The authority also clarified that reports of the T-5 tunnel collapse were inaccurate, stating that the main tunnel, under-construction power house, tailrace culvert, and switchyard remained unharmed. Furthermore, Wapda reassured the public that there were no casualties or loss of life among the workforce.
