The Hospital Canal (joining the Durançole) and the Crillon Canal (1775) were dug to irrigate the territories of Montfavet, Pontet, and Vedène. They were divided into numerous "fioles" or "filioles" (in Provençal "filhòlas" or "fiolo"). Similarly, to irrigate the gardens of the wealthy south of Avignon, the Puy Canal was dug (1808). All of these canals took their water from the Durance. These canals were initially used to flood the land, which was very stony, to fertilize them by deposition of silt.
