Press Release by EPM
The reservoir of the Ituango hydroelectric project reached on Sunday, November 4, the level 405 meters above sea level (msnm) and began to pour safely and controlled by the structure designed for this purpose.
After achieving this important milestone for the rehabilitation of the future power generation plant, the General Manager of EPM, Jorge Londoño De la Cuesta, indicated that "in our company we continue working tirelessly in the contingency and in the recovery of the project always thinking about the safety of the communities located downstream of the dam, with the development of works that include: the reinforcement of the press with the flexible screen in benthic cement, the plugging of the tunnels and the stabilization of the mountain. , that the reservoir is pouring allows us to analyze other factors to determine when it will be possible to interrupt the flow of water through the powerhouse. "
To close the water passage through the machine house, one of the conditions is to have the landfill operating, but we must also observe how the dam, the landfill itself and the operation of the gates behave when closed at that level of the reservoir. Decisions that are made every day to continue with the project.
So the landfill works
The landfill of the Ituango hydroelectric project operates in a normal manner and with all the technical and safety conditions for this type of works. The landfill has a length of 405 meters and four radial gates, 15.4 meters wide by 19.5 meters high, through which passes the water to reach a well of quieting, where it is incorporated into the riverbed. normal of the Cauca river.
The four dump gates are enabled today to operate remotely and each of their channels are finalized. Initially, the left channel of the landfill was put into operation, where 200 m3 of water per second are evacuated. The landfill is designed to travel upstream of the Cauca River and its upper elevation is located at 401 meters above sea level (masl) of the dam and begins to pour at the level 405 meters above sea level.
These 200 m3 are now added to the 750 m3 of water flowing through the powerhouse for a total of 950 m3 of water on average, a lower flow rate than the Cauca River historically presents at this time of the year, which ranges from 1,200 and 1,300 m3 of water per second. In this way, the ecological flow necessary for the habitat in the Cauca River is guaranteed, which is 450 cubic meters of water per second and the safety of the communities that live downstream of the project is guaranteed.
The landfill of the Ituango hydroelectric project is not free flowing, where the water arrives and simply overflows, on the contrary, EPM has control way with the gates, which allows to maneuver and decide how much water can be thrown. With this, the flow of the Cauca River of environmental regulations (450 m3) is guaranteed.
This is how EPM progresses in a responsible manner in the recovery of the Ituango hydroelectric project, the future power plant that will provide 17% of the energy that the country needs to continue growing and contribute to the quality of life and well-being of millions of people. Hope is still alive, Hidroituango is Colombia.
What is the landfill?
The landfill is a hydraulic structure designed to allow the free or controlled passage of water in generation plants. It allows the water to be bathed when the reservoir reaches its maximum capacity limit and guarantees the safety of the dam, preventing the dammed water from overflowing the structure.
How big is the landfill of the Ituango hydroelectric project?
It has a total length of 405 meters and a width between 70 and 95 meters, by way of comparison, the soccer field of the Atanasio Girardot stadium in Medellín measures 110 meters long by 73.5 meters wide, therefore, the channel of the landfill corresponds to about four soccer fields.
How does it operate?
The landfill of the Ituango hydroelectric project has four gates through which the water passes, which is carried by an equal number of channels to a stilling well to stabilize its strength and return it to the Cauca River.
