Vigiñas Excavation

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

Likewise, the 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 tanks excavated in the surface of the soil in the form of an inverted cone, through which water can be stored or harvested in the rainy season for use in the dry season, when other sources are available, such as temporary rivers and others have dried up.
