The plain constitutes more than half the area of the town (1,275ha) which has long been neglected by fear of floods. In the 18th century, it was conquered on the river by building dams in order to control the Durance. A fruit and vegetable agriculture has developed there. 600km of canals allow each plot of land to be irrigated and drained. A mill, a factory (beetroot refinery), a power plant bear witness to the past use of the driving force of the water.
