Water Statistics Activities under the PHARE and TF-Programmes – Lessons learned, Challenges for the Future Meeting of the Working Group "Statistics of the Environment“ Sub-Group "Water“ 9 - 10 October 2007 Luxembourg Michael Nagy

Contents of the Presentation Some slides about the 2001 and 2004 PHARE / TF Programmes on Water Statistics Results Lessons learned, recommendations and challenges for the future

Facts about PHARE and TF Projects on Water Statistics 1st Project (PHARE 2001): Project Period 2003-2004 Wastewater Tables 4-7 Project organisation: BC Grants + external experts + 2 Workshops 2nd Project (PHARE 2004, Transition Facility 2004) Project Period 2006-2007 All JQ-Tables Project organisation: BC Grants + external experts + 3 Workshops

Main Objectives of the Programmes Significant and lasting improvement of response rates to JQ Consistency of JQ-data with WFD, UWWTD, EPER/PRTR,… Expert reports with proposed action points Country specific guidelines assisting in the application of the Eurostat data collection manual for the JQ on Inland Waters Expert Report on the completeness and quality of the data collected and transmitted to Eurostat in 2006 Online helpdesk for the duration of the project Synthesis report summarizing the key issues for all BCs

Participating Countries Legend: P = Pilot project :Eurostat Grant M = Mission by external expert

Types of Pilot Projects Inventories on UWWTPs and industrial water users Glossaries and national water statistics manuals Setting up rules for cooperation of NSI with other institutions Database development Modification of existing NSI questionnaires according to JQ terminology and structure Re-classification of activities according to NACE Linking of registers of different institutions Use of emission coefficients Use of GIS for water statistics

Results I: Improved Response Rates Optimized use of existing data: Initiation of formal and informal cooperations between NSI and other institutions Motivation to provide data which is calculated or estimated Initiation of new data collections e.g. UWWTD-Registers Use of coefficients, e.g. hydraulic capacity / load  p.e. calculation of emission loads calculation of water abstraction and water use

Results II: Improved Data Quality Clear and agreed national terminology Development of quality checking procedures Multiple use of data (consistency and coherence) Use of metadata

Institutional Dimension Institutional Cooperation: Required the Consideration of 3 or more Dimensions… Institutional Dimension Water Authorities Ministries Env. Agency NSI Water Assoctiation Hydrographical Institute Households Industries Agriculture Thematic Dimension Wastewater Water abstraction and use Hydrography Sewage Sludge Reporting Dimension UWWTD WFD JQ on Inland Waters Sewage Sludge-Directive EEA WISE SEIS

Results III: Proposal for (small) modifications of the JQ on Inland Waters Extension / clarification of definitions Clear up inconsistencies  change / deletion of some definitions Structured metainformation-system

Examples for proposed changes of JQ Definitions to be changed, e.g: „Other wastewater treatment“: include WW treatment of army camps, hospitals, hotels… seperate „industrial wastewater treatment“ (tbd) Explanation of difference between „Total sludge production“ and „Total sludge disposal“ Clear definitions for „Septic tanks“ and „Cess pools“ „Industrial (process) wastewater“ is misleading and could be deleted Structural changes of the JQ: Type of WW collection in Table 7 Metadata system: simple to fill in, considering data coverage, accuracy and determination of data (M/C/E) „Recharge minus ecological discharge“ really necessary? Link to Water Accounting (e.g. SEEAW, NAMEA Water): To be discussed…

Discussion of „tricky“ case examples I City 5. How to consider the WW of this city in the JQ? 6 Factory fence of softdrink producer (NACE 15) Car pool Activity: NACE 60 4 5 Wastewater of car pool 3. Is this to be considered as water supply to NACE 60 1 Wastewater of water purification unit Water abstraction and purification for own use (operated by softdrink producer) Activity: NACE 41 IWWTP Activity: NACE 90 10 94 Wastewater of bottling unit Electricity production Activity: NACE 40 4. How to consider this WWTP and its WW in the JQ? Bottling unit Activity: NACE 15 19 100 149 150 1. ´Water abstraction by NACE 15 / 41 / 40? 100 or 250 units? 2. Is this cooling water discharged by NACE 15 or 40? IWR

Discussion of „tricky“ case examples II City Discussion of „tricky“ case examples II Factory fence of softdrink producer (NACE 15) How to report the water supply of this city in the JQ? Car pool, NACE 60 2 Wastewater of car pool Canteen, NACE 55 3 Wastewater of canteen 30 2 Wastewater of water purification unit 1 1 Water abstraction and purification for distribution and own use, NACE 41 Wastewater treatment, NACE 90 5 64 Wastewater of production and bottling Electricity production, NACE 40 Softdrink production and bottling, NACE 15 8 100 149 150 IWR

Lessons learned / Recommendations Inter-institutional cooperation is very important (formal or informal): NSI Environment Agencies Ministries Hydrographical Institute Water Association … Covering all themes of T1 – T7 Covering all relevant EU Directives and EEA-Reporting  Implement and maintain a system of IDs which allows links to other databases

Lessons learned / Recommendations Double-check reported classification of activities (which establishments might be considered differently in different reporting frameworks and water accounts?) Double-check the used classifications, in particular: UWWTP other WWTP Sludge generation / sludge production Independent treatment Collecting system Septic tank Cess pool

Lessons learned / Recommendations Use existing data!!! PRTR for industrial emissions UWWTD-Reporting for UWWTD data WFD-Reporting Provide metainformation (footnotes): Coverage of data (e.g. > 80% of emissions) Source of data (e.g. PRTR) Accuracy of data Determination of data (measured / calculated / estimated) Don‘t provide blank cells (if data is not available, indicate „n.a.“) Develop a national glossary on water statistics terms together with water administration In case of „tricky situations“ (e.g. public water supply is carried out by a soft-drink company)  case by case decision, but be consistent in time series.

Challenges for the Future JQ as data basis for water accounts? How to deal with principal / secondary / ancillary activities? Maintenance of a JQ-Hotline / Helpdesk? Integration of JQ on Inland Waters into WISE Data on diffuse pollution Structural changes of the JW on Inland Waters Change / extension of existing definitions Benefit from the WISE on the data input side Further promote the use of JQ data

…and don‘t forget the social aspects of water statistics Thank your for your attention!
