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) Discharge and treatment
of waste water
by the industrial sector
Statistic on public water supply andurban waste water disposal (§ 6 UStatG)
Statistic on water use and waste water disposal by mining, quarrying,manufacturing industry (§ 7 UStatG) and by production of electricity (§ 9 UStatG)
2.) Procedures, contents of the waste water statistics in Germany Structure of waste water management and statistics

6 P:independent waste water disposal
(municipalities, 13 364)
-Population without connection to urban waste water collecting systems including connection to small sewage treatment plants and discharge less pits
-Population connected to urban waste water collection systems without treatment
6 S: urban sewerage
(municipalities or companies, 7 159)
-Kind, length and year of construction of the sewerage network-Number and storage volume of the sewage system for rainwater
-Ways of transmission for the collected waste water including (volume)+ transmission to urban waste water treatment plants+ direct discharge into environment (including the location)+ transmission to industrial treatment plants
-Population connected to industrial treatment plants
6 K:urban waste water treatment
(municipalities or companies, 10 188)
-Kind of waste water treatment:primary, secondary, tertiary treatment
-Connected population (number and actual occupation in terms of inhabitant equivalents, BOD)
-Design capacity in terms of inhabitant equivalents, BOD-Volume of waste water per year-Location of discharging into water bodies-Concentration of selective emissions -Number of plants and storage volume of the sewage system for rainwater
-Sewage sludge production, treatment and disposal (tons of dry solids)

7 A / 9 A:Part IV Waste water generation and discharge
-Origin of waste water (cooling or production processes)-Transmission to + urban waste water collecting systems and treatment plants+ own industrial treatment plants + other external industrial treatment plants
-direct discharge into environment (including the location) and concentration of selective emissions
7 B / 9 B: Waste water treatment
-Kind of waste water treatmentprimary, secondary, tertiary treatment and special procedures
-Transmission to+ urban waste water collecting systems and treatment plants+ other external industrial treatment plants
-Transmission to another own industrial treatment plant -direct discharge into environment (including the location) and concentration of selective emissions
-Sewage sludge production, treatment and disposal (tons of dry solids)
Respondents: units of mining, quarrying, manufacturing and production of electricity (2001: 10 548)

3.) International Reporting on waste water (e.g. Joint Questionnaire)
Table 4: National population connected to waste water treatment plants
+ everything is available up to one position- not available: independent waste
water collecting system including secondary treatment
Table 5: Treatment capacity, in terms of BOD for the different types of treatment
Table 6: Sewage sludge production and disposal (volume and tons of dry solids) for the different types of treatment

3.) International Reporting on waste water (e.g. Joint Questionnaire)
Table 7: Part I - VolumeWaste water generation by point sources (different sectors) and non point sources
+ data are available for most of the industrial sectors
- no data from agricultural sector or construction sector
- no data for non point sources
Waste water discharged by type of collecting system
+ most of the data are available - no delivery of data on waste water
reused and for the detailed positions of waste water generated by the domestic sector
Table 7: Part II - BOD, COD, Suspended Solids, N-Tot, P-Tot, As, Population Equivalents, selected hazardous substancesfor the same classification than in part
- data are only available on effluents of urban treatment plants for COD, N-Tot und P-Tot

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
• 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)
