Project Details


The reservoir would be used to provide irrigation security in the area surrounding the Chillán river, which is an agricultural region. The irrigation infrastructure along the river is in disrepair and inefficient. Many water intakes are in poor condition or placed above the typical water level of the river. Building a reservoir would provide 85% irrigation security to 8,788ha, allowing for a significantly larger cultivated area than the 3,110ha that are planted.
