WAPDA confirms workers safe after water enters tunnel
A WAPDA spokesperson said the rock collapse occurred during excavation of the second bench of the connecting tunnel at the Tarbela 5th Extension Hydropower Project.
The collapse allowed water to flow from the intake pit into the connecting tunnel and the powerhouse being constructed.
Workers were immediately evacuated. WAPDA said no loss of life was reported.
The spokesperson added that water had been completely drained from the intake pit, while efforts to remove water from the powerhouse were continuing.
