Eurostat – the general & legal setup The Statistical Office of the European Union A Directorate-General of the European Commission „European Statistical Law“
(Regulation EC 223/2009 of the European Parliament and of the Council of 11 March 2009)
– statistical governance and quality principles
– European Statistical System (ESS): NSI + all national authorities developing, producing and disseminating official statistics
Individual statistical laws for various domains – e.g. Regulation 2150/2002 on European Waste Statistics
ESS cooperation / coordination– EFTA + EU Candidate countries
– other International Organisations

Water losses – definition (JQ-IW)
Volume of water lost during transport
through leakage or evaporation
between a point of abstraction and a point of use,
between a water supplier/distributor and a point of use
or between points of use and reuse.

Water use - definition (JQ-IW)
In contrast to water supply (i.e. is delivery of water to
final users including abstraction for own final use),
water use refers to water that is actually used by end
users for a specific purpose within a territory, such as
for domestic use, irrigation or industrial processing.
Excludes returned water (19).

Resident population - definition (JQ-IW)
The average over a year of the number of persons
belonging to the permanent population living in a
territory.

Challenges ahead for (European) Water Statistics
Drivers: EU Water Framework Directive, SDS,… Climatic change floods and droughts
Current statistics are incomplete and insufficient!
Response needed: Reliable + adequate water statistics Completeness filling of gaps, additional information Coverage better resolution in time and space Quality improve accuracy & timeliness
