Our work consists in finding, through the application of the cost-effectiveness analysis method, the optimal investment sequence, that would cover, with a lower cost, the future water demand in the Algerian coastal basin 02a, by the horizon 2030. Eight supply management and demand management measures were studied and the results show that demand management measures, which promote water saving and the rational use of this resource, have better cost effectiveness ratios than supply management measures. The ranking of these cost-effectiveness ratios allows us to stagger and prioritize the different investment projects in the water sector, with the aim of achieving the dual objective, social (meeting the water demand) and economic (minimize public spending).
