La Savasse

The Savasse, which flows through the communes of Peyrins, Mours Saint Eusèbe and Romans sur Isère, can flood the inhabited areas of these communes. In 1993, overflows from the Savasse flooded dozens of homes and caused considerable material damage. Faced with the need to protect the population, the Communauté de Communes du Pays de Romans, which came into existence in 2007, embarked on a vast project to control flooding on the Savasse. From the Peyrins bridge to the Isère river at Romans, the major project to protect against a 100-year flood involved the creation of 6 flood expansion fields formed by 6 dams and a discharge channel to the Isère. These works were accompanied by various ecological restoration sites: winding of the Savasse and the Béal Rochas, tiered vegetation adapted to the watercourse, restoration of wetlands and creation of ponds. The various flood protection structures are well integrated into the landscape thanks to their vegetation. The effectiveness of all these measures was demonstrated during the last major flood on October 23, 2013. Today, these structures are managed by the GEMAPI (Gestion milieux aquatiques et prévention des inondations) department of Valence Romans Agglo.
