CMGO Bretagne Sud


UEPG Sustainable Development Awards 2020

Grand-Champ -

The objective of CMGO Bretagne Sud Carrière de Grand-Champ was to create and restore 400 linear metres of watercourses and thus act as a drain for adjacent wet plots. To facilitate the installation and to ensure the return of fish, several weirs had to be strategically positioned and caches were established. Three years after the restoration of the watercourse, the objectives had been achieved, low-water level support is provided even in winter, winter overflows ensure the evolution of wetlands and the feeding of ponds. Each year, an engineering firm (ALTHIS) carries out a follow-up study that shows that species have recolonised the watercourse.
