10. Work on NAMWA in the Netherlands Based on an experimental NAMWA published in 1996Based on an experimental NAMWA published in 1996 Collaboration between RIZA and Statistics NetherlandsCollaboration between RIZA and Statistics Netherlands 2002: Extension of original NAMWA2002: Extension of original NAMWA 2003-2005: further extension: addition of more pollutants, more detail for river basins2003-2005: further extension: addition of more pollutants, more detail for river basins

11. Scale: National and River Basins

13. Economic parameters – National: overview of the expenses (vertical) and receipts (horizontal) with specific attention to water (waterboards, sewage taxes etc.) – Regional: production, use, value added, number of employees per industry

23. Water accounts Water survey from the CBS (national and regional) every 5 years production and use of fresh water (ground-, surface- en drinking water) per NACE

24. Use of water in 2001

25. Results so far National NAMWA for 1996 t/m 2003 Regional NAMWA for 1996 t/m 2002

26. Usefulness of NAMWA for WFD (1) NAMWA provides a consistent integrated economic- environmental accounting framework which provides information about: - Intensity of water use by branches of industry - Intensity of water use by branches of industry - The physical flows of supply of water services - The physical flows of supply of water services - Production costs of water services - Production costs of water services - Environmental taxes related to water - Environmental taxes related to water at National and River Basin level at National and River Basin level

27. Usefulness of NAMWA for WFD (2) Hence NAMWA provides indicators about: - Extent and relative significance of water services - Extent and relative significance of water use - Cost recovery - Application of Polluter Pays Principle
