The Barrios de Luna, Villameca, Selga de Orgás, Benamarías, Valdesamario and Azud de Santa Marina dams, included in Zone A of the Operating System of the Duero Hydrographic Confederation, are of vital importance for the supply of water for both the irrigation of around 52,500 ha in the Páramo Leonés region and the supply of local populations, including the cities of Astorga and León, among others.

  • Technical inspections of dams.
  • Analysis of the performance of the dams.
  • Review of the dam auscultation system.
  • Technical Support to the Operations Manager.
  • Provision of support personnel for the operation of the dams
