The missions of GEOS, a subsidiary of the Ingerop group, consisted of designing a fish ladder for the existing Verbois dam. Due to the significant fall and in order to enhance the attraction flow in terms of energy efficiency, the construction of this crossing structure for fish was combined with a hydroelectric micro-plant for the use of the attraction flow.
