Image of Legutio, not of the place itself.

The Urrunaga reservoir (also called Santa Engracia), inaugurated in 1957 on the river Zadorra, has been connected since 1973 by a 15.5 km gallery, 4.25 m in diameter, to the Biscay reservoir of Undurraga in Barazar; after generating electricity, the water is channeled through another tunnel of about 16 km to the water treatment plant of Arrigorriaga, to supply Bilbao.
