The first phase of the preliminary study will last 4 months and will consist in carrying out a preliminary technical study of the 21 sites identified in the watersheds. At the end of this study, the list of a maximum of ten identified sites will be validated
The second phase will consist in the realization of preliminary design studies on the 10 priority sites to confirm their feasibility on all required aspects. At the end of the Preliminary project studies, which will last 4 months, a maximum of five efficient sites will be selected that present immediate financing opportunities
The third phase is the study of the preliminary designs and the preparation of the tender documents for the five sites selected in the second phase. The PDA studies on these five sites will allow, from extensive field investigations, to define the precise characteristics of the dams and the various associated hydro-agricultural facilities. The CAD will allow the preparation of the tender notice for the construction of the dams on the five sites studied
