  1. OVERVIEW OF QUANTITY AND QUALITY WATER MANAGEMENT IN SPAIN Ángel García Cantón Head of Hydrological Planning and Studies Department CEDEX SPAIN

  2. NATURAL CONDITIONS CONCERNINIG WATER RESOURCES Precipitation Year UNESCO moisture index ( EUROSTAT) Time A singular case in the European context Irregularity Average annual natural runoff 109,000 hm3 Space )

  3. Superficial Groundwater Both TOTAL WATER DEMAND Demand for urban supply(mm/year) Total water demand (mm/year) 5,000 hm3 Industrial demand (mm/year) 6,500 hm3 Demand for irrigation 24,500 hm3 Urban, industrial & agricultural demand 36,000 hm3

  4. WATER BALANCE Total resource(mm/year) Total demand (mm/year) - + Water shortage (mm/year) Water surplus(mm/year) Measures are necessary

  5. Natural regulation Current regulation Average natur reg. Average current reg. INCREASING AVAILABLE RESOURCES THROUGH DAM REGULATION % Natural cumulative flow River basin name

  6. DAM CONSTRUCTION DEVELOPMENT IN SPAIN Num dams Year Storage Number Cumulative storage Storage Cost (2006)

  7. Inhabitants equivalent WATER QUALITY STATUSBY THE 1990’S Mean general quality index Measures continue to be necessary

  8. INTEGRATED APPROACH: RIVER BASIN MANAGEMENT PLANS FIRST RIVER BASIN MANAGEMENT PLANS IN 1998: Integrated approach quantity and quality (essentially from a chemical point of view) • NEW RIVER BASIN MANAGEMENT PLANS TO BE FINISHED BY THE END 2009 (WATER FRAMEWORK DIRECTIVE) • Integrated approach quantity and quality from an ecological point of view • Environmental requirements represent previous conditions to water resources systems • Meet environmental objectives for water bodies Measures are taken to Satisfy water demands )

  9. 368 Hm3/year 836 Hm3/year 1,030 Hm3/year NON CONVENTIONAL RESOURCES WASTE WATER REUSE Next planning cycle 2009 2015 DESALINATION Planned measures in Mediterranean coast to increase production to get 900 hm3/year IRRIGATION SYSTEMS IMPROVEMENT • Efficiency increase in irrigation (up to 2008): • acts on 570,000 ha • foreseen water volume to be saved: 1,400 hm3/yearinvestment cost: 1,500 Million € • A new plan to start in 2010 is in preparation

  10. IMPROVEMENT OF FLUVIAL SYSTEMS NATIONAL STRATEGY FOR RIVER RESTORATION • Restoration of aquatic and riparian ecosystems • Reduction of floodplains fragmentation • Reduction of river fragmentation WATER QUALITY NATIONAL PLAN: 2007-2015

  11. 19,372 million € WATER QUALITY NATIONAL PLAN: 2007-2015Main objectives Secondary treatments in all agglomerations > 2,000 p.e. in inland waters and estuaries and > 10,000 p.e. in coastal waters, where it is not installed yet (77% p.e. compliant in 2005).Appropriate treatments in agglomerations < 2,000 p.e. in inland waters and estuaries and < 10,000 p.e. in coastal waters.Stringent treatment in agglomerations > 10,000 p.e in sensitive areas, including latest declared sensitive areas (84% p.e. compliant in 2005).Collecting systems and devices for the limitation of pollution of receiving waters due to storm water overflows (stormwater tanks).Improvement in R&D about biodiversity and water quality

  12. DROUGHT MANAGEMENT PLANS FOR EACH RIVER BASIN (finished 2006) • CLIMATE CHANGES STUDIES • Impact on natural water resources (provisional assesments used in river basin managment plans) • Impact on water demands • Impact on water ecosystems • Impact on water resources availability
