This project, led by the Syndicat Intercommunal d’Assainissement de la Haute Vallée du Garon (SIAHVG), follows a public inquiry conducted in 2026. The inquiry commissioner submitted their reasoned conclusions on June 9, 2026.
The decree authorizes the execution of the works in accordance with the general work plan attached. It also stipulates that any expropriation of parcels necessary for the project must occur within a period of five years from the decree's publication.
The decree is published in the official administrative records of the Rhône prefecture and will be displayed for two months at the town hall of Soucieu-en-Jarrest. The project plans can be consulted at the Rhône prefecture and the town hall, or downloaded online.
