Resilient Cities 2012 3rd Global Forum on Urban Resilience and Adaptation Bonn, Germany12 - 15 May 2012Jan BondarukAnna Siwek-SkalnyCentral Mining Institute KatowicePoland

11Introduction

Page 2 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.

22Introduction

Page 3 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 pressureSuperficial demographic trends analysis demographic forecastUnderestimated tarrifs affordability analysis Insufficient consultancy undefined risksOrganisational changes and transformations W&S system in transitionDisregard of legal and environmental law tendencies (i.e. sludge management) EU and national law coherence

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 Euro1577 agglomerations >2000 PE

Complex investment programme (Masterplan) launched 2002 and finished 2009 was co-financed by Cohesion Fund ca. 45 mln Euro (Phase I)

Investment phase of WWTP GigablokNowadays it is conducted Phase II of the Masterplan (additional 161 km of sewage will be constructed and 2 WWTPs will be modernised) Till 2015 it is planned to invest ca. 305 mln Euroas a result 93% of inhabitants will be connected to sewage network

Operating phase40 000 m3 per day PE = 200 000Electricity is cogenerated from biogastogether with heat (yield - 300 m3/hr)

1010Integrated Water Resources 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 Water Partnership (), 2000).Integrated Water Resources ManagementObjectives 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 objectives at urban level need to be redefined including specific local conditions.

IUWM Integrated Urban Water Management

Integrated Urban Water ManagementIntegrated 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 urban water cycle??

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.

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.

Net unit price for water supplied and sewage disposal in selected cities in Poland, 2011In some cities the tariff for sewage services doubled during last decade

One decade of IUWM - key findingsRisk and comparative analysis of available technical and financial options (forget about proven solutions not adjusted to your local conditions),Complex analysis of investment and longterm 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 involved local societies are needed to enhance successful implementation of IUWM.

One decade of IUWM - key findings

WWTPs as a centres of education?? Why not, it really works

Heat and electricity production from biogas as a by-product of wastewater sludge digestion Implementation of water network hydraulic model divided into supply clusters (SCADA) = more effective management and significant water losses decrease)Specific pollutants load menagement effective collaboration between industry park and sewage water treatment plantWWTP technology circuits (for agglomertaion above 100 thou of PE) are modernised for increased biogen (N, P) removal IUWM - good examples

To implement holistic 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.Page 22

Goals of the project: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.

REURIS connects experiences of 8 partners from 6 cities Plze and Brno (Czech Republic), Stuttgart and Leipzig (Germany), Bydgoszcz and Katowice (Poland).
