  1. Water Framework DirectivePatrick de VisscherMinistry of Transport and Water Management- National water board

  2.

  3. Stepwise development of ECP (part I) • Divide management area in water surfaces with homogeneous functions • Determine water quality goals per function • Determine status quo of water quality • Determine critical parts per function

  4. Stepwise development of ECP (part II) 5. Determine intervention level for each critical part (maximal acceptable risk, negligible risk) 6. Determine sources 7. Determine maintenance strategy 8. Put strategy into operation

  5. Source analysis (I) 137 kt/yr = total Dutch emission (1999)

  6. Source analysis (II)

  7. Measures - example: nitrogen emission • Emission limits per type of water body • Reduce nitrate emission by agriculture and communal wastewater through co-operation with local water boards • Law enforcement of 75% reduction duty • Industry state of the art N-sewage treatment • Reduction N-emission by yachting (toilets)

  8. Conclusion (I) • Distinguish general and typical problematic components • Use legislative possibilities: enforce! • Don’t forget effect of water bottom • Set up an adequate monitoring program • Run-off of agricultural land and ditches important

  9. Conclusion (II) • Weighing of measures (cost-effect) useful • Harmonization with WFD necessary • Harmonization with water boards and other regional water departments efficient
