WETLANDS RECOVERY

Two wetlands in the Region of Murcia with reclaimed wastewater have been included in the RAMSAR CONVENTION LIST OF WETLANDS OF

INTERNATIONAL IMPORTANCE ( January 4th, 2011)


ACHIEVED OBJECTIVES


• MORE WATER : 100 Million m3

• SEGURA RIVER RECOVERY

• WETLANDS RICOVERY (TWO ‘RAMSAR LIST’)

• EU WASTEWATER TREATMENT DIRECTIVE (100% Agreed)


The ‘General System for Wastewater Reclamation and Reuse. Region of Murcia’ has been awarded
