Cadagua

The Cadagua or Kadagua River drains the Biscayan area of Encartaciones (Basque: Enkarterriak), from the Castilian valley of Mena to Barakaldo and Bilbao, where it forms the border between these municipalities and ends at the Estuary of Bilbao.

Cadagua village is located in Valle de Mena (Burgos, Spain) surrounded by the beautiful landscape of "La Peña" mountains.

Four small hydropower plans produce electricity thanks to the river Cadagua.

Until the last decades of the 20th century, this water power was also used by several mills that can be nowadays seen by the river basin.

This company designs, plans and builds water treatment plants in order to improve the environment.
