Réalisations

In response to the decline of the Souss aquifer, which threatened the agricultural perimeter of Sebt El Guerdane, the Mokhtar Soussi Dam was built on the Oued Aouzioua (a tributary of the Souss) and inaugurated in 2002. SGTM participated in the construction of this concrete-faced earthfill dam, approximately 62 m high, which creates a reservoir of 50 million m³ and regulates 45 million m³ per year. A distinctive feature is the transfer of water to the nearby Aoulouz Dam (20 km downstream) via a 90 km feeder canal, designed to optimize regional distribution. Mokhtar Soussi secures irrigation for 10,000 ha in the Guerdane–Oulad Teima plain, an area threatened by aridity, and also contributes to the local drinking water supply. The works included the construction of an embankment totalling 1.8 million m³, installation of a lateral flood spillway (design flow ~3,450 m³/s), and integration of structural monitoring equipment (instrumentation for dam auscultation). SGTM ensured the stability of the structure in sedimentary terrain through close geotechnical monitoring. The dam strengthens the Souss-Massa hydraulic system and has been designed to allow for a future heightening (a planned project aiming for a 200 million m³ capacity).
