  1. Contents of the presentation • Introduction: Water and waste water situation in Germany • Procedures, contents of the waste water statistics in Germany • International Reporting on waste water (e.g. Joint Questionnaire) • Problems to fulfill the requirements

  2. 1.)Introduction: Current data The German river basin districts according to theWater Framework Directive

  3. 1.)Introduction: Current data Key data: Rain-laden climate: precipitation 779 mm

  4. 1.)Introduction: Current data 1) Incl. foreign water and precipitation water from the sewage system, excl. unused water.

  5. 1.)Introduction: Current data

  6. 1.)Introduction: Current data

  7. 1.)Introduction: Current data

  8. 1.)Introduction: Current data

  9. 2.) Procedures, contents of the waste water statistics in Germany Structure of waste water management and statistics Disposal of waste water generated by the domestic and the industrial sector through urban waste water collection systems and treatment plants run by municipalities or companys (governmental or private) Statistic on public water supply and urban waste water disposal (§ 6 UStatG) Discharge and treatment of waste water by the industrial sector Statistic on water use and waste water disposal by mining, quarrying, manufacturing industry (§ 7 UStatG) and by production of electricity (§ 9 UStatG)

  10. 2.) Procedures, contents of the waste water statistics in Germany Statistic on urban waste water disposal

  11. 2.) Procedures, contents of the waste water statistics in Germany Statistic on industrial waste water disposal Respondents: units of mining, quarrying, manufacturing and production of electricity (2001: 10 548)

  12. 3.) International Reporting on waste water (e.g. Joint Questionnaire)

  13. 3.) International Reporting on waste water (e.g. Joint Questionnaire)

  14. 4. Problems to fulfill the requirements General reasons: • For collecting new data a modification of the law is necessary • The long tradition hinders modification • Actually the politics plan to reduce the „statistical burden“ for enterprises • „ Länder“ also collect data, this results in double surveys parallel to the statistics- Water politics are primarily in their hand - The European Commission requires data, e.g. Urban Waste Water Directive“ • Other additonal data collection: Environmental agency; EPER • Data collection is conducted only every three years • Some sectors are not included (services, contstruction, agriculture) • Overlapping parts are difficult to report while the statistics are subdivided in two parts

  15. 4.) Problems Institutions in charge 16 „Länder“ (states) Ministries of environment Regional Environment agencies Regional authorities Federal governement Federal ministry of environment Federal environment agency Wastewaterpolicy Regional statistical offices Regional Environment agencies Regional authorities Federal statistical office Federal environment agency Federal agency for Water Protection German meteorological agency Data collection Several associatons

  16. 4. Problems to fulfill the requirements Specific reasons • Degree of detailing is particular very high, but • the political need is not clear • the tables are often organized from a more theoretical point of view • Deviation of definitions Conclusion • Concentration of the priority data • Extension of the use of other databases (UGR, EPER) • Improvement of coordination between the different requirements(primarily within the EU)
