In Morocco, artificial reservoirs often constitute the principal source of water supply. Yet, they faced natural risks such as the siltation, this phenomenon is increasing in all dams around the world. As a result, governments are constantly looking for innovative solutions and encourages studies in this field. In this perspective, we are trying to valorize the mud from the reservoir of one of the oldest and most important dams in Morocco; the Lalla Takerkoust dam, which is suffering from high sedimentation rates. This study is subdivided into two parts, a social part where we conducted questionnaire surveys, and a technical part, where we carried out a series of physicochemical and mechanical analyses on sediment samples collected from the Lalla Takerkoust reservoir. The results obtained show that the sediments of the studied reservoir can be used in several domains, which the local population can use to improve their living standards by setting up social enterprises.
