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).

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 Coverage Quality  filling of gaps, additional information  better resolution in time and space  improve accuracy & timeliness
