A major hydroelectric venture being constructed in Pakistan with Chinese assistance has run into serious trouble. A sudden failure of a temporary barrier designed for protection has occurred at the fifth extension project, known as T-5, of the Tarbela Dam situated in Haripur within the Khyber Pakhtunkhwa province. Following this unexpected collapse, a massive volume of water rushed directly into the under-construction tunnel.
Realizing the gravity of the deteriorating situation, authorities immediately evacuated all personnel, including Pakistani laborers and Chinese engineers, from the site. While initial reports confirm that no casualties or injuries occurred in the incident, the development work on the project has been brought to a halt for an indefinite period.
Significance for the National Power Grid
This infrastructure project holds immense importance concerning Pakistan's pressing electricity requirements. Upon successful completion, it was expected to inject an additional 1,410 megawatts of power into the country's electricity grid. However, with the main tunnel now inundated with water, uncertainty looms over when work will resume.
According to the Deputy Commissioner of Haripur, the protective barrier erected at the construction site to hold back water gave way abruptly. Consequently, water began surging rapidly into the main tunnel of the T-5 project.
Panic and Swift Rescue Operations
The temporary structure had been intentionally put in place to prevent water seepage during the excavation and construction phases of the tunnel. Its sudden rupture triggered panic across the work site. Rescue teams acted swiftly, managing to safely evacuate all the Chinese engineers and local workers in time.
Local officials and individuals associated with the project have pointed fingers at the Chinese contractor, citing negligence as the primary factor behind the accident. Nevertheless, the exact cause of the failure will only be determined after a thorough investigation concludes.
Uncertainty Over Timelines and Damage Assessment
The fifth extension of the Tarbela Dam serves as a critical component of Pakistan's broader strategy to expand its power generation capacity. Its core objective remained adding 1,410 megawatts of capacity to the national grid.
Draining the accumulated water from the tunnel and assessing the structural damage sustained inside is expected to take considerable time. Consequently, authorities fear significant delays in meeting the project deadlines.
A high-level inquiry has been initiated to probe the accident. This investigation will specifically examine how the temporary water-retention barrier failed and where safety protocols fell short.
