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).

15
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
