Hydraulic millrace: The "Caz"

 
Hydraulic curve channel and power plants

The different enclaves are connected by pathways and the historical curve channel, whose older parts, dated from 1821, were made by Agustín de Larramendi (considered the first Spanish civil engineer). Above the original design of pipelines and water storage ponds, made by the pioneer Juan Jorge Graubner, this channel lead the waters of the stream Gollizo and others, necessary for the well functioning of hydraulic devices such us wheels, egrets and so on... all the way through 5 km of channelling.

It surpassed the dependence on seasonal fluctuations in rivers and streams, stocking up with a hydraulic flow more or less constant. This channel represented a structural change of the whole factory, relocating some cores to more efficient operation. In the 40-50 years of the twentieth century  the Caz  was improved to give movement to the  six hydroelectric power station, wich allowed the energetic independence of Riópar Factories.

From Toma del agua, the Caz (Spanish name for the channel) streams along the village of Gollizo, and the different industrial cores: San Rafael, San Juan, San Pablo, San Carlos and San Luis. From San Miguel to San Jorge the water used to be conducted by a wooden channel, prior being collected in the dam designed by Carlos Lemaur in late eighteenth century.

Around the charming landscape of Riópar you can walk, cycle, drive or even ride a horse to explore the joys of nature.  At the tourist office within the museum, you will be helped out on your route planning.
