3. Database for water use statistics Background
Reporting
EU/OECD Joint Questionnaire, Regional Q
EEA reporting
National reporting
Various data sources for the reporting
Various ways of reporting the data
Various data for the reporting
Various variable definitions

4. Database for water use statistics Background
Briefly
Reporting has been a mess!
Time consuming and difficult to report data of high quality

5. Database for water use statistics Objectives
Facilitate future JQ-reporting
Reporting on environmental objectives
Calculating data for various reports
Data are secured for the future
Server system with routines of backup
Storage of data is secured

6. Database for water use statistics Tasks
inventory of data sources for JQ-reporting
listing variables and data format
modelling the database
constructing a database compatible with the system at Statistics Sweden
constructing an interface for registration of data
importing existing data into the database
designing functions for data extraction according to JQ    
documentation of the system
report writing

7. Database for water use statistics Method
All available data sources for JQ-reporting were identified and analysed
Variables and data formats were listed

8. Database for water use statistics Method
Data tables included in the database:
Agricultural water use
Water for livestock
Water for irrigation
Public water supply
Public water delivery to municipalities
Public water purification plants and points of withdrawal
Water for households, private supply
Water for industry
Nuclear energy plants

9. Database for water use statistics Data
Most recent available data
Data originates from years in a range from 1985 to 2004
Geographical levels (parish, municipality, county and water district)
Type of water: surface water, ground water, non fresh water (marine and brackish water) and water of unknown origin
Data on wastewater has not been included in the first version of the database

10. Data was imported from different sources
AF01 Livestock
Subject actor
<<System>>
WaterDatabase
AF03 Industry
AF05 Water and sewage standard
AF06 Municipality
AF07 Codes
AF02 Irrigation
AF04 Nuclear power plant
Data was imported from different sources

11. The database consists of the following tables

12. Database for water use statistics Technical implementation
The application was developed in Visual Studio.Net and the DBMS MS SQL Server 2000 has been used.
For instance to import data on livestock, choose the alternative “Import, Jordbruk, Djurhållning” as shown in the application user interface below.

13. Database for water use statistics Technical implementation

14. Database for water use statistics Conclusions
Prerequisites:
integration can be performed between two tables only if they are aggregated to the same geographical level.
Waste water:
no clear connection between the waste water statistics and other water statistics at Statistics Sweden.
Needs a lot more manual preparations to manage the JQ-demands. Future work.

15. Database for water use statistics Conclusions
Possible improvements:
To add data on municipal sewage treatment plants and waste water. A good starting point would be to include data on waste water for the most water-consuming industries, which already are incorporated in the file "Water for industry“
To add data on water accounts

16. Database for water use statistics Conclusions
Possible improvements:
To add data on water use for private and public services outside urban areas
More recent and more accurate data is also desirable
