Hydroitango reduces the possibility of avalanches



The reservoir reached level 405 and opened the first gate of the landfill so that the water flows safely and controlled. Now the work will focus on closing the flow of water through the plant, where there are turbines of electricity production.

The Ituango hydroelectric power plant reached a level of 405 meters above sea level yesterday and began to pour out and control the structure intended for this purpose, EPM said in a statement on its website.

"The Hidroituango Landfill works in a normal way and with all the technical and safety conditions. The landfill has a length of 405 meters and four radial gates, 15.4 meters wide and 19.5 meters high, through which water flows to the well, where it is built into a trough the river, the normal river Cauca, "they said.

For EPM, this action has reduced avalanche capability in municipalities such as Valdivia, Caceres, Taraza, Caucasia, El Bagre and Nechi; which are located downstream from the hydroelectric power plant and which were at risk from a huge avalanche; however, the authorities keep a warning in case of any case.


EPM Manager, Horhe Londono de la Cuesta, explained that after reaching level 405, it was ordered to open one of the four doors of the landfill.

EPM Director Jorge Londono de la Cuesta explained that, after reaching level 405, it was ordered to open one of the four doors of the landfill, which allowed the evacuation of about 200 cubic meters of water per second. For now, the three remaining gates will remain closed while behavior is monitored.

Now, the main objective of the EPM is to close the flow of water through the plant, where there are turbines of electricity generation. The manager said he would continue to work on strengthening dams with a flexible screen in benthic cement, closing the tunnel and stabilizing the mountain.

In a dialogue with Caracol-Radio, Osvaldo Ordonez Carmona, a professional engineer-geologist and professor at the National University, convinced communities that they could feel calm because leaving the Cauca landing at the landfill gave a piece of calm, the most significant since the beginning to defend the river by collapsing one of the tunnels to redirect Hidroituango.

"Let's say the project is well 50%, it surely means the dam works for which it is designed, the project is 50% saved because dams and landfills together account for 50% of the work and it's a very good thing," said Professor of the National University of Medellin.

During the Hidroituango crisis, which took place six months ago, the force with which the waters of the Cauca River collapsed Puerto Valdivia corregimiento, destroying more than 60 houses and two pedestrian bridges. At least 120,000 people are at risk of plant failure, which would, if rescued, generate 16 percent of the country's electricity.
