We emphasize in our hydraulic heritage the set of Islamic arcades, that extend the orchard lands. In the lower part of the ravine of the Castle, we find the Raft and Ark of the Gatell, and in the ravine of Adzeneta, the Ark and the Azud of the ravine d''At. These two arcades carried drinking water to Bèlgida. The Andalusían Big Ark aqueduct represents the beginning of the irrigation ditch of the Huerta Nueva de Carrícola. Its factory is made of irregular masonry, joined with mortar, while its ditchgutter, is built with solid clay brick.
