The Minister of Housing added that this step comes after the completion of the civil works qualified to install the parts of the first turbine, while the total number of 9 turbines, each turbine of them reaches a capacity of 235MW with a total of 2,115MW, and civil works are carried out in parallel throughout the day without interruption. These works are carried out by the Egyptian engineers and technicians and their Tanzanian brothers. The Minister of Housing indicated the great interest and continuous follow up of President Abdel Fattah El Sisi - President of the Republic, for this project which is of great importance in highlighting cooperation with African brothers.

Eng. Sayed Farouk expressed his great appreciation for the support provided by the Egyptian government through supervision and follow up by the Ministry of Housing, Utilities and Urban Communities. He pointed out that 158,000m3 of compacted concrete has recently poured into the dam body within 20 days to take advantage of the current dry season. Thus, the total amount of compacted concrete poured in the project reached 685,000 m3 since the river diversion on 18th November 2020, in addition to the temporary dam works to retain water which required 85,000m3 of concrete, besides the rest of the project component. He added that the project witnessed rock explosions and drilling with a quantity of 2.5 million m3, and 50,000 m3 of concrete was poured for the Power House building. Eng.

Besides, the construction of a hydropower plant with a capacity of 2115mw. The plant is located on Rufiji River in Selous Game Reserve at Morogoro area, South West of Dar es Salam (largest city and commercial capital of Tanzania). It will be the biggest plant in Tanzania with a capacity of 6307 MW/hour yearly; the generated power will be transferred by 400kv transmission lines to a substation where the generated power will be merged with the public power grid. In addition to these, the project includes the construction of 4 saddle dams for reservoir impounding of water. Besides, the main spillway is located on the center of the main dam, an emergency spillway and a tunnel with a length of 660m to divert the water of the river. In addition to the construction of 3 tunnels to transfer the water to the power plant, a permanent concrete bridge and 2 temporary bridges on Rufiji River.
