Nine river basin agencies are responsible for the management of water resources in Morocco. River basin agencies have a number of important responsibilities. They authorize water abstractions and wastewater discharges for all users, based on a basin master plan ("Plan directeur d'aménagement intégré des ressources en eau", PDAIRE) that they prepare. They also collect charges for abstraction and effluent discharges. They are also supposed to provide financial help and technical assistance to service providers for the prevention of water pollution and the efficient use of water resources. They also monitor the quality and quantity of both surface and groundwater and are in charge of managing water-related emergencies. Finally, they should increase public awareness about water resources. The agencies cover the following basins ranked in the order of the available water resources in each basin: Sebou River, Moulouya River, Oum Er-Rbia River, Bou Regreg River, Tensift River, Loukkos River and the Souss-Massa basin, Ziz-Er Gheris et Sakia el Hamra-Oued Eddahab. The means available to the basin agencies are largely insufficient to carry out their functions.
