sectors

- no delivery of data on waste water reused
and for the detailed positions of waste
water generated by the domestic sector

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

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)
