  1. IUWM for Silesia Metropolitan Area: towards holistic basin management in urban spaces. Resilient Cities 2012 3rd Global Forum on Urban Resilience and Adaptation Bonn, Germany Jan Bondaruk Anna Siwek-Skalny Central Mining Institute Katowice Poland 12 - 15 May 2012

  2. Introduction Polish cities, especially in Silesia Metropolitan Area, in the face of progressive social and economic transformation, concentrate on reconstruction of their function from industrial to wellbeing cities aware of their environmental constraints and challenges resulted from heritage of heavy industry age.

  3. Introduction • Structural and cohesion funds significantly supporting Polish cities in a long-term transition process towards more sustainable settlements. • Cities concentrate on investments in water and sewage water infrastructure. • Analysis of the last decade of investment boost in this field lead to following remarks: • „To spend funds” attitude – political pressure • Superficial demographic trends analysis – demographicforecast • Underestimated tarrifs – affordability analysis • Insufficient consultancy – undefined risks • Organisational changes and transformations – W&S system in transition • Disregard of legal and environmental law tendencies (i.e. sludge management) – EU and national law coherence Page 3

  4. SMA location Page 4

  5. SMA potential • Silesia Voivodeship: • Inhabitants: 4,64 million • Area: 12 334 km2 • Silesia Metropolitan Area: • Inhabitants: 2 million (and 300thou. in Katowice - region capital city) • Area: 1 218 km2

  6. National obligations 1577 agglomerations >2000 PE The National Programme for Municipal Waste Water Treatment (NPMWWT) This document imposed on the Polish Government the obligation to construct, expand and/or modify municipal waste water treatment plants and combined sewerage networks in agglomerations by the 2015 time horizon. The total implementation cost of the NPMWWT in 2005 - 2015 amounts to about 42.6 billion PLN. ~app. 10 bilion Euro Page 6

  7. Changes in lenght of sewerage network in selected cities in Poland, 1999-2010

  8. W&S Investment in Silesia Metropolitan Area • Investment projects for • water and sewage system: • Żory, 2005 - 2008 • Rybnik, 2008, 2010 • Cieszyn, 2006 - 2009 • Kłobuck, 2007 – 2008 • Zawiercie, 2005 • Będzin, 2004 - 2007 • Katowice, 2005-2011 • …….. Percentage increase in municipal sewage systemin 2002 – 2010 Area covered by sewage system in 2010

  9. Sewage system in Katowice Investment phase of WWTP Gigablok Complex investment programme (Masterplan) launched 2002 and finished 2009 was co-financed by Cohesion Fund ca. 45 mln Euro (Phase I) Operating phase 40 000 m3 per day PE = 200 000 NowadaysitisconductedPhase II of theMasterplan(additional 161 km of sewage will be constructed and 2 WWTP’s will be modernised) Till 2015 itisplanned to invest ca. 305 mln Euro as a result 93% of inhabitants will be connected to sewagenetwork Electricity is cogenerated from biogas togetherwithheat (yield - 300 m3/hr) Page 9

  10. Complexity of projects Water and sewage management in Żory – filling the gaps in the system • Project aimed at: • approximately 106 km of gravity sewage system, • approximately 11 km of discharge sewage system, • 21 pumping stations, • 1 water pumping station, • 45 km of storm water collectors, • 17 separators, • 8 potable water reservoirs, • 60 km of water supply network, • the water treatment plant expansion and reconstruction of the sewage treatment plant. App. 50 mln Euro investment cost Page 10

  11. Integrated Water Resources Management IntegratedWaterResources Management (IWRM) is a process which promotes the coordinated development and management of water, land and related resources in order to maximise economic and social welfare in an equitable manner without compromising the sustainability of vital ecosystems and the environment(Global WaterPartnership (…), 2000). • Objectives of IWRM at river basin level: • Achievement of water security, • Risk management, • Effective and reliable delivery of water services, • Coordinating and balancing the various water-using sectors as a part of sustainable water management. • IWRM objectivesat urban level – need to be redefined including specific local conditions. IUWM – Integrated Urban Water Management

  12. Integrated Urban Water Management Integrated Urban Water Management (IUWM) takes a comprehensive approach to urban water services, viewing water supply, stormwater, groundwater and wastewater as components of an integrated physical system and recognizing that the physical system sits within an organizational framework and a broader natural landscape. Understanding of urbanwatercycle?? This integrated approach enable synergies to be identified and realized, providing opportunities for more sustainable, more cost-effective solutions to the challenges of managing the urban water cycle.

  13. General barriers… • Barriers for implementation of the IUWM principles: • Passing costs on the end user (false and unfavourable interpretation of the "polluter-pays" principle), • Lack of legal and economic mechanisms ensuring an interregional (transboundary) cooperation, • There are no uniform methodology for determining the urban catchment (sewage system, morphology). • Lack of system solutions for the analysis of changes in sewage catchment resulted from urbanization and imperviousness of the area. The riverbasin do not respectadministrativeboundaries

  14. TRADITIONAL APPROACH • Drainage systems • Troubleshooting • Dominant role of engineers • Protection of property • Pipes and ducts • Administrativedecisions • Ownership of Local Government • Focusing on extreme phenomena • Action on “the peakflow!" • INTEGRATED APPROACH • Ecosystems • Prevention (Preventing impacts) • Multidisciplinary teams • Protection of property and the environment • The imitation of natural processes • Decisions based on consensus • Broad partnership • Rainwater management, integrated land use • Action on „thecatchment capacity"! Sustainable rainwater management Page 14

  15. Business „as usual” Local flooding, higher operational costs, signifficant impact on aquatic ecosystems (degradation and accumulation) The amount of supplied water / discharged sewage (dam3/year)in Silesia Year supplied water discharged sewage Page 15

  18. Net unit price for water supplied and sewage disposal in selected cities in Poland, 2011 In somecities the tariff for sewage services doubledduringlastdecade

  19. One decade of IUWM - keyfindings • Risk and comparative analysis of available technical and financial options (forget about „proven” solutions not adjusted to your local conditions), • Complex analysis of investment and long–term operational costs including environmental fees to avoid „unpayable” tariffs for water and sewage services, • Demographic trends and migration scenarios are important factor of water and sewage networks effectiveness, • Combined sewage systems should be transferred into separate sewage and storm water systems. • Public participation in the WFD implementation process of is required at each stage of the planning circuit. • Aware, well educated and involvedlocal societies are needed to enhance successful implementation of IUWM.

  20. One decade of IUWM - keyfindings WWTPs as a centres of education?? Why not, it really works

  21. IUWM - goodexamples • Heat and electricity production from biogas as a by-product of wastewater sludge digestion • Implementationof water network hydraulic model dividedintosupplyclusters (SCADA) = moreeffective management and significantwaterlossesdecrease) • Specificpollutantsloadmenagement – effectivecollaborationbetweenindustry park and sewagewatertreatmentplant • WWTP technologycircuits(for agglomertaionabove 100 thou of PE) aremodernised for increased biogen (N, P) removal

  22. To implementholistic „principles” – project REURIS The overarching aim of REURIS project is to implement strategies and activities at reconstruction of natural and cultural resources and management of urban river spaces. REURIS connects experiences of 8 partners from 6 cities –Plzeň and Brno (Czech Republic), Stuttgart and Leipzig (Germany), Bydgoszcz and Katowice (Poland). www.reuris.gig.eu • Goals of theproject: • implementation of strategies and activities aimed at revitalisation and management of urban river spaces, • testing strategies and tools in practice and assessment of effectiveness, • consensus among all interested parties (e.g. local tenants, planners, administrators of water resources), • integration of spatial, socio-economic and engineering issues in the process of preparation, realisation and management of the implemented activity, • creation of common set of methods & procedures allowing for coordinated work of multidisciplinary teams as well as effective stakeholder involvement.

  23. Challenges • Water management integrated with land use planning and local development including catchment dimension =>better understanding of interrelations between spatial planning, pollutant discharge and quality of water bodies (surface and groundwater) in reference to specific local conditions • Scenario and credible data base analysis (quantitative and qualitative) => BALANCING SYSTEM OFPOLLUTION LOADS INCATCHMENT SCALE • Networking collaboration between researchers, decision-makers, ecologists and engineers as well as harmonisation of interest groups to mitigate an intense pressure of urban areas on aquatic environment. • Practical implementation of decision support tools and cyclical analysis as a part of resource and service management, • Organizational and system solutions (including cross-sector and transboundary cooperation), • Identified and visualized risks with reference to WFD principles.
