Excavation of Vigiñas
Vigiñas are excavations in the ground with a diameter of approximately 10 to 20 meters and a depth of 1 to 2.5 meters. These technologies provide water for the dry season and help the regrowth and growth of forage species. Likewise, vigiñas or qotañas can be of different sizes and storage capacities, depending on the water requirement and availability of areas for their construction.

Likewise, vigiñas or qotañas can be of different sizes and storage capacities, depending on the water requirement and availability of areas for their construction. These technologies are water deposits dug into the surface of the ground in the form of an inverted cone, through which water can be stored or harvested in the rainy season to be used in the dry season, when other available sources, such as temporary rivers and others, have dried up.
