  1. MunServNet - Component B - 1st Expert panel11-13 July 2006, Chania Perspectives and priorities in drinking water in Debrecen Zoltán Karácsonyi University of Debrecen Centre for Environmental Management and Policy József Ányos Debrecen Waterworks Co.

  2. Developments regarding drinking water • Main fields: • Water production • Water network

  3. Developments in water production • Water supply concerns • 85.000 households • 13.735 thousands m3/year • Reconstruction of the drinking water supply system in 2000-2002

  4. Reconstruction of the drinking water supply system in 2000-2002 (1) • Main reasons for the reconstruction: • Level of capacity exploitation has been reduced to 50% • Cost effectiveness declined • 4,1 million CHF (~ 2,6 M EUR) support – SECO (Swiss State Secretariat for Economic Affairs) • 57% of total costs ensured by SECO • Implementation started on 11.12.2000

  5. Reconstruction of the drinking water supply system in 2000-2002 (2) • Results: • Structural modernisation, living labour saving (46 persons instead of the earlier 96 persons) • Changes in cost structure (depreciation instead of maintenance costs, reduction in other input) • High-rated automation • Energy savings, reduction of electricity use • Service safe • Improvement of water quality

  6. Reconstruction of the drinking water supply system in 2000-2002 (3) • New equipments in • Water production (wells, submersible pump) • Water cleaning (filters, disinfection)

  7. Reconstruction of the drinking water supply system in 2000-2002 (3) • Control engineering system • 2-step system: • Global level (city) • Basic level (sub-unit) • Drinking water supply (network pumps, water tower)

  8. Developments in water network (1) • Main developments between 1995-2003 • Water network expansion • 86 km network built • Important contribution of the inhabitants

  9. Developments in water network (2) • Number of households connected into drinking water network

  10. Developments in water network (3) • Number of inhabitants getting public water supply

  11. Laboratory developments (1) • Quality measures (2004) • Drinking water: 1,85 (number of analysis divided by stipulated number of analysis by national law) • Exceeding the limit: in case of drinking water: 0,3%

  12. Laboratory developments (2) • Latest development • New central laboratory inaugurated in November 2005 • Up-to-date laboratory technology • 1300 m2, 62 rooms • Investment: about 1,5 million EUR • Chemical, biological, microbilogical analysis relating to water supply • Quality control of wastewater and wastewater sludge

  13. Drinking Water Quality Improvement (1) • Programme for the Hungarian North Great Plain Region • Existing problems: • fragile water bases • Secondary pollution • micro-pollution • No water treatment technology is applied with a large number of settlements • over-dimensioning of the distribution pipes • material of pipeline is mainly rigid, fragile asbestos-cement (network loss – 25-45%)

  14. Drinking Water Quality Improvement (2) • 1st phase project approval: August 2005

  15. Drinking Water Quality Improvement (3) • 1st phase project elements • Technology: technological developments at the 25 waterworks (filter equipments, electronic control units, chemical feeding equipments, pumps, dehumidifier basins etc. ) • Pipeline reconstruction: Changing the sections of worst quality in the pipeline networks of the settlements (breaks, leakage, asbestos-cement material) • Network cleansing: Improve the remainder parts of networks for enabling the cleansing by foam swabbing – investment-type developments (bolts, connection elements, branches etc.)

  16. Drinking Water Quality Improvement (4) • 1st phase financial background • 75% EU support (Cohesion Fund) • 15% Hungarian governmental co-financing • ~3-5% Fund of Ministry of Home Affairs • ~5-7% Municipal own resources

  17. Drinking Water Quality Improvement (5) • 2nd stage preparations • North Great Plain Regional Development Council provided support for the starting the preparation: it bases the planning phase • New situation analyses finalized December 2005 • Further support from National Development Office – appr. 2,8 Million EUR for the complete preparation (planning, FS, CBA, EIA, AF, tender documentations etc.)
