The acquaintance of the Head of State Emomali Rahmon began on the place of overlapping of the river and the process of construction of the upper dam. As the Founder of Peace and National Unity - Leader of the Nation, President of the Republic of Tajikistan, His Excellency Emomali Rahmon was informed, the total amount of work on the dam is 2.7 million m3. After the change of the riverbed, Salini Impregilo layed more than 2 million m3 of a mixture of stones and gravels for the construction of the dam. At present, 23 to 26 thousand m3 of overlapping materials are filled and fixed per day for the construction of the dam and the gateway of the first stage of the hydroelectric power station.
According to the information of the responsible persons of the Rogun HPP, along with the execution of ground operations, welding and installation of control and measuring equipment was also carried out simultaneously. It was reported that 47 units of control equipment have been connected and installed at the dam of the power plant until today.
According to the design and technology of dam construction, it is necessary to import 32,200 m2 of geomembranes building materials that are produced in Europe. Geomembranes are installed in the front part of the lock in parts and layers in a mixture with other protective materials and layers, which is provided for the overlap of water.
At present, the welding and installation work of the geomembrane on the dam is being continued, up to date they were completely connected and installed on an area of more than 18 thousand m2, joints continue to be connected. The installation of this anti-filtering material will enable the water from the reservoir to flow through the sluices. In Tajikistan, this is the first experience.
The Leader of the Nation, Emomali Rahmon, during his conversation with the Roghun HPP engineers and builders instructed them to pay attention to quality and safety first of all, since this "Temple of Light" is vital for the nation and guarantee of a dignified life for the people of Tajikistan.

Today, Leader of the Nation, Emomali Rahmon also got acquainted with the progress of work in the construction of tunnel of the third tier, which is considered the main facility of the Roghun HPP. The length of tunnel is 1,794 meters and it has the capacity to contain 3500 m3 of water per second.
The third tier tunnel, as a spill tunnel, is mainly used to regulate water in the reservoir of the power station in the probable cases, including when the water level in the Vakhsh River increases. The Head of State Emomali Rahmon, during his acquaintance with the site of the construction of the repair-emergency gates located at the entrance area of the named tunnel, gave specific instructions and tasks to the responsible persons of OJSC "Rogun HPP" and the contractors' companies for the timely completion of the remaining work.
It was stressed that the construction of the repair-emergency gates was fully completed taking into account all the requirements and modern construction standards, and now the work is progressing steadily at the gate control facilities.
Also all works are fully completed in the construction tunnel No. 3, from the entrance to a distance of 994 m. The Leader of the Nation Emomali Rahmon, during familiarization highly appraised the quality of the completed works and called the construction of this tunnel, which is considered one of the main stages of the construction of this hydroelectric power plant, important and timely for the accelerated continuation of the construction of the Rogun dam.

It should be noted that the main emergency-repair gates, if necessary, serve to prevent high water pressure. With this in mind, the vertical tunnels and the strength of the gates are comprehensively studied and constructed using special iron sheets.
During the construction and after the complete commissioning of the Roghun Hydroelectric power station, in cases of rising water levels in the river and reservoir, the gates in the named tunnel automatically open and eliminate the possible emergency cases. In this case, the gate opens, and the excess water of the reservoir flows into the river.
It was stressed that the monthly volume of connected and installed glands and metals in the construction tunnel of the third tier is on average about 400 tons, and in total this figure reached 4191 tons. Tunnel and anchor work on the inclined side and on the exit section of the tunnel are completed, nowadays the workers and specialists in some sections are engaged in reinforcing, concrete and cement work.
At the exit of the construction tunnel of the third tier, President Emomali Rahmon was informed that till today ground works in the volume of more than 1 million m3 have been completed.
At present, construction works in this tunnel are continued in two-shift basis, i.e. day and night. The Head of State Emomali Rahmon, during his acquaintance with the process of implementation of works in the construction tunnel No. 3 and conversations with workers and specialists, stressed that this is an important measure to continue the creative work in the Rogun Hydroelectric Power Plant, which is aimed at the achievement of full energy independence.
