Pakistan's strategic important project "Diamer Bhasha dam" is under construction since last quarter of 2019. This multi-purpose dam will be used for water storage, flood mitigation, divert water for irrigation and vitally for generation of cheap energy. Since then, the construction activities are going on around the clock and accelerated with the passage of time.
On Indus River near Chilas (Khyber Pakhtunkhwa & Gilgit-Baltistan), 315 km u/s from Tarbela Dam, and about 40 km downstream of Chilas Town.

The construction of the permanent bridge over Indus River is in progress. Three temporary cable bridges are already providing access for heavy vehicles of the project.

To build the 272 meters high dam, a diversion system with two tunnels and a diversion canal has been designed. The excavation works at the diversion system going on and gaining momentum with the passage of time. Millions of cubic meters of excavation are involved with high-cut slopes. The excavation works are in progress and tons of explosive material and hundreds of earthwork machinery are being utilized.

About 2,000 m long diversion tunnels are being excavated on left bank of Mighty Indus River. About 16.9m heigh and 16m wide tunnels will divert the river water and provide the area for dam founding. The excavation and support work of diversion tunnel number 2 has already been completed and the concrete lining of the tunnel and works on the inlet structure are in progress.

Recently Chairman WAPDA visited the construction site and it was apprised that all is set for diversion of Indus river through diversion tunnel in dry sesson (November, 2023).

Before the construction of main dam, Upstream and downstream coffer dams are designed to construct. The foundation works, drilling of cut off wall, plastic concrete works are in progress. More than 8,000 square meter drilling has been involved. The drilling has been divided into different panels. After completion the drilling, the plastic concrete are being poured.

Several percussion drilling machines and grab machine for debris removal are engaged to complete the task. To fulfil the construction needs of concrete, the construction of the main batching plant, aggregate processing plant and Power generation plant are in progress.

The project completion is scheduled in 2029. On completion, the Dam will have a gross water storage capacity of 8.1 million acres feet to irrigate 1.23 million acres of additional land. It will also provide 18 billion units of green and clean hydel electricity to the National Grid per annum.
