Drought Management Plans were passed by the ORD MM/698/2007, of 21 st march 2007, led by the Dirección General del gua, developed by River Basin Organizations and with the support of the Drought xpert ommittee. he recurring and severe droughts that egura River Basin has suffered have been the main reason for the designation of this basin as: Water carcity and Drought Pilot River Basin.

11 4.3 Regulations ROYL DR 1620/2007, of 7th December, on ewage water reuse. R U It establishes legal procedures which allow to use treated sewage water as an alternative water resource, and at the same time fostering plans dealing with water reuse and with more efficient use of water resources. It defines the reuse term, it introduces the renewed water concept, it establishes the necessary requirements to carry out the utilization of renewed water and the procedures to obtain the legal water rights, and it includes regulations about admitted uses and minimum quality requirements in each case. Besides, it gathers minimum quality criteria to meet when using renewed water in each case of use. Before its reuse, sewage water has to undergo a renewal treatment to meet health and environmental required quality levels, which will be different for each type of use. Renewed waters will be allowed to be used for urban, agricultural, industrial, recreational and environmental purposes. ertain uses are banned for being dangerous to health and environment.

26 O L U I O OLUIO egura River Basin is characterized by a permanent water scarcity situation and by frequent drought episodes, increasingly severe. his situation requires an integrated water resource management, considering the different water sources (surface water, groundwater, water transfer, reuse, desalination) It has been absolutely necessary to develop a wide and efficient hydraulic infrastructure for urban supply, irrigation and other uses. he legal framework regarding water management together with a suitable economic and financial regime allow the existence of organisms like Mancomunidad de anales del aibilla (M) and Public organisms in charge of sewage water treatment (MUR, PR) which provide urban supply fares and sewage water treatment fares, which are economically and financially affordable. Water Framework Directive challenges for Mediterranean river basins, like eguras s, will need the developing of new suitable economic and financial mechanisms, from the point of view of recovery of costs, in order not to endanger water-related economic activities
