  1. Official European Water Statistics water losses water use in private households Jürgen Förster, Eurostat E3 Environment and Forestry Statistics

  2. 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 and water use in private households

  3. Cooperation in environment statistics • Partners in Europe • DG Environment • European Environment Agency (EEA) • Joint Research Centre • ”Group of 4“ • International coordination • OECD • United Nations (UNSD, UNEP, UNECE, FAO,…) Water losses and water use in private households

  4. OECD – Eurostat Joint Questionnaire (JQ) 1/2 • First developed by the OECD in the early 1980‘s • Joined by Eurostat in the early 1990‘s • Voluntary exercise  gentlemen‘s agreement • Several domains: waste, water, land use, wildlife,… • Biennial collection of yearly data for national territories • EU + CC + EFTA + neighbours (+ non- European OECD) • World Standard for official Water Statistics Water losses and water use in private households

  5. OECD – Eurostat Joint Questionnaire (JQ) 2/2 • JQ-Inland Waters: • Water Resources (tab. 1) • Water Abstraction (tab. 2) • Water Use (tab. 3) • Wastewater Treatment (tab. 4 – 7) • Water Quality of Rivers and Lakes (tab. 8 & 9) European Water Statistics - 2nd IWA Conference WESF

  6. Water statistics in pre-defined tables: Water losses and water use in private households

  7. Water losses and water use in private households

  8. JQ-IW Response rates by table Water losses and water use in private households

  9. Tab. 3.1: Water use by supply category and user European Water Statistics - 2nd IWA Conference WESF

  10. 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 losses and water use in private households

  11. Water flow scheme (JQ-IW) 14.08.2014 Water losses and water use in private households

  12. Water losses par capita, m³ per year Water losses and water use in private households

  13. Water losses par capita, m³ per year Water losses and water use in private households

  14. 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). Water losses and water use in private households

  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. Water losses and water use in private households

  16. Sectoral structure of JQ-IWreference to ISIC / NACE 14.08.2014 Water losses and water use in private households

  17. Water use in private households (m³ per year)latest available year (2009 … 2000) Water losses and water use in private households

  18. Water use in private households (m³ per year) Water losses and water use in private households

  19. Water use in private households - share of self supply (%) Water losses and water use in private households

  20. ESTAT Water statistics activities ahead • Regional aggregation (REQ 2012): NUTS and RBD • Data link into WISE (water.europa.eu) • International coordination and harmonization • Alignment with water accounting (SEEA-water) • Quality improvement / Enhanced EU country commitment Water losses and water use in private households

  21. Thank you for listening! Water losses and water use in private households

  22. Water Statistics Seminar for EECCA countries • 11 -13 September 2012 • Almaty, KZ • 2 participants per country • Co-operation withthe European Environment Agency • EU experience + regional experience • Topics: resources, cross-boundarywatermanagement, abstractions & use, wastewatertreatment Water losses and water use in private households

  23. Water losses and water use in private households

  24. First results of pilot projects: Bulgaria Water losses and water use in private households

  25. 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 Water losses and water use in private households
