Residents of Arles and nearby towns such as Port-Saint-Louis, Beaucaire, Saint-Gilles, and Tarascon may notice patrol teams inspecting dikes on Tuesday, October 13. This is a full-scale exercise required by the Municipal Safety Plan and the Dike Decree for the Symadrem, a regional organization responsible for managing dikes in the area. The test, held every two years, ensures that teams follow proper procedures and can effectively use equipment in case of an emergency. The exercise will take place throughout the day, with a command post set up in Arles to coordinate activities. This will involve mobilizing all staff and deploying surveillance teams across about 250 kilometers of dikes managed by the syndicate. The area has been divided into 51 sectors based on the local municipalities. During the exercise, teams—made up of municipal agents or local volunteers—will walk the dikes to detect fictional disturbances, such as water inflows, erosion, subsidence, cracks, and overflows. These teams will be supervised by six dike guards from the Symadrem, who will maintain direct communication with the command post in Arles. The exercise comes at a time when Pierre Raviol, the newly elected president of the Symadrem, has taken on the role of leading the association France Digues. Created in 2013 by the Symadrem and the Symbhi, France Digues brings together local authorities to improve dike management and represents them to the Ministry of Ecological Transition. The association currently includes 193 members who oversee 4,000 kilometers of dikes across the region.
