The configuration of the departmental estate of the Chateau d'Avignon, leaning on the banks of the Petit Rhône, indicates that, from the 18th century on, mastering water for irrigation and the desalination of the lands was a fundamental stake in the enhancement and exploitation of the Camargue.

At the end of the 19th century, conversions in the estate bore mainly on the modernization of the hydraulic network. From the river, the water is canalized, purified and distributed by machines, basins, canals and pipes. Moving, the water flows in a discreet manner, from drop by drop to evaporation, or noisily circulates in the powerful brewing of the pumps and water circuits.

These technical spaces are dedicated to providing comfort and hygiene.
