Some misconceptions about Diamer Bhasha Dam need to be addressed.
Its construction has been under scrutiny since the 1980s. The initial feasibility report was prepared by MONENCO of Canada. He proposed the construction of a clay-filled ECRD. It was not a CFRD nor was the dam designed by General Safdar Butt.
A detailed feasibility study conducted by the NECA consultant, which included top experts, considered different types of dams. CFRD and ECRD were also reviewed and rejected on the following grounds.
2) The means of obtaining plastic clay were not available in adequate quantities, so ECRD could not be constructed. 2
2) The soil brought by the river was soft and full, which means that anything built on clay will not be sustainable. Therefore, laying the foundation of the dam on this soil was ruled out
2) There are many cases of Glacial Leak Out Burst Flood (GLOF) in the northern areas of the Indus River. This leads to sudden floods. ECRD or CFRD can be filled and such dams cannot afford full filling. But an RCC dam can afford it.
Considering the above and many other issues, RCC type dam was proposed. It was claimed that the cost of CFRD would be half that of RCC. This is incorrect because the cost was estimated at a detailed feasibility stage and the cost of CFRD and RCC was the same.
Another concern in the media is the delivery of cement and other goods from Khyber Pakhtunkhwa via the Karakoram Highways. This is definitely a challenge. During the feasibility and design testing phase, some solutions were proposed by reviewing the transportation of the goods and the problems encountered. Another very important point is that various experts have presented reviews for the construction of dams on the Indus River in the same area. These include Bunji Dam and Dasu Dam, among others.
All these experts suggested RCC type dams. From all the technical and technical distractions, the same conclusion was reached that RCC Dam is the best option for this area. The initial feasibility study of the Bhasha Dam was carried out in 1984 by the Montreal Engineering Company of Canada (MONENCO). The goal of the review was to build a dam with a capacity of 3,360 megawatts of electricity and 5.7 million acre-feet of water. It was reviewed by countless individuals and organizations.
The feasibility study report was reviewed by Diamer Bhasha Consultants, Engineering Design and Tender Documentation, with the support of Lemar International Germany and Barqab & PES, AMEC Canada.
The DBC proposed was a 272 m high RCC dam with a capacity of 4,500 MW to generate electricity and store 6.4 million acre feet of water. It is worth mentioning here that DBC used many studies done during the previous work.
The global panel of experts invited included Fabio Villages, Hydropower Layout Planning Expert, Dr. Walter Whitkey, Rock Mechanics Expert, Brain Forbes, RCC Expert and Dr. Abdul Shakoor, Geologist. The Diamer Bhasha Dam has gone through three phases, Feasibility Study (1984) and Detailed Design (2008).
Internationally renowned Pakistani firms have completed the design, which is now ready for construction. Therefore, it is wrong to say that the dam project has not been revised.
It was said that an RCC dam would not be able to withstand an earthquake. There is no technical evidence for this claim. All the dams in the world are built in mountainous areas. The sites of all the dams are the same. It is also a well-known fact that these areas are prone to earthquakes, so dams are designed to withstand earthquakes.
It has very strict design, very strict technical inspection and excellent quality. All international standards for Diamer-Bhasha Dam were set and adopted.
Earthquake hazards are the same for all dams. The key features of the dams are that they are able to withstand this intensity.
Nespak is the largest consultancy firm in Pakistan. It has extensive experience and expertise in building dams in Pakistan and other countries. He skillfully completed a number of projects, such as the Ghazi Brotha Hydropower Project, the Neelum Jahm Project and the Mangla Dam Elevation Project. The Dia Marbhasha construction project is a joint effort involving Nespak, Harza, Stan Tech, Poora, Dolsar, Mitt McDonald International, China Water Resources Biafang.
Some misconceptions about the Kala Bagh Dam are also being linked to the current project. The Pakistani nation cannot live without water and electricity while waiting for the resolution of the Kala Bagh Dam dispute. It faces severe shortages of water and electricity.
Apart from Diamer Bhasha Dam, other dams should also be built. Now the construction phase of Diamer Bhasha has started. We have already suffered a lot because of the Kala Bagh controversy. We have poured billions of dollars into these conflicts. No more stupidity.
