European Water Research Series – serie

First book to consider citizens playing a role in the science-policy interface to help formulate durable responses to sustainability challenges Discusses all aspects to enhance the connectivity of actors in the sustainable water management field, with three pilot case studies showing how citizens and stakeholders can be engaged early and effectively in the river basins and coastal waters planning processes Provides tips and recommendations for the transferability of the approach in different coastal areas of Europe and beyond. Sustainable Water Ecosystems Management in Europe examines the anthropogenic deterioration of water ecosystems, in particular in coastal areas. It proposes a new approach to enhance connectivity between research and policy-making. The book exploits the concept of integrated adaptive ecosystem management, by engaging scientists, policy makers and the public (the latter including both stakeholders and lay citizens/water users) in comparable case studies. Emphasis is given to the role of the public to enlarge the concept of organisational learning to the wider concept of social learning. The EC 7th Research Framework Program funded project AWARE engaged a panel of randomly selected citizens living in three different coastal areas of Europe – in a pilot experience of knowledge brokerage with water scientists and decision makers focused on coastal waters quality.  Results and lessons learned from the project are summarized in this volume, and recommendations are made for this pilot’s replication and transferability to different coastal areas and sustainable water management tasks - and beyond to other sustainability research and policy issues. This book is a must-read for water managers and policy makers looking to effectively organize citizen and stakeholder participation in river basin and coastal water planning, as required by the EU Water Framework Directive. Sustainable Water Ecosystems Management in Europe provides useful recommendations for organising effective participation of citizens in the science and policy dialogue, promoting a collective awareness of the plans and actions needed to protect the water environment and ensure sustainable use of water resources. Editor: Carlo Sessa, AWARE Project Coordinator, Director at ISIS – Institute of Studies for the Integration of Systems, Italy

The European project MINOTAURUS explored innovative bio-processes to eliminate emerging and classic organic pollutants. These bio-processes are all based on the concept of immobilization of biocatalysts (microorganisms and enzymes) and encompass bioaugmentation, enzyme technology, rhizoremediation with halophytes, and a bioelectrochemical remediation process. The immobilization-based technologies are applied as engineered ex situ treatment systems as well as natural systems in situ for the bioremediation of groundwater, wastewater and soil. The selection and application of tailored physico-chemical, molecularbiological and ecotoxicological monitoring tools combined with a rational understanding of engineering, enzymology and microbial physiology is a pertinent approach to open the black-box of the selected technologies. Reliable process monitoring constitutes the basis for developing and refining biodegradation kinetics models, which in turn improve the predictability of performances to be achieved with technologies. Immobilised Biocatalysts for Bioremediation of Groundwater and Wastewater delivers insight into the concepts and performance of a series of remediation approaches. A key strength of this book is to deliver results from lab-scale through to piloting at different European reference sites. It further suggests frameworks for structuring and making evidence-based decisions for the most appropriate bioremediation measures.

CARE-W was a joint European initiative to develop a framework for water network rehabilitation. The project was supported by the European Commission under the Fifth Framework Programme for Research and Development. The aim of CARE-W was to support European water companies in their decisions on upgrading their water supply. The system has been developed for and tested by cities representing all parts of Europe. CARE-W consists of software dealing with fundamental instruments for estimating the current and future condition of water networks, including tools to assess performance indicators (PI), to predict pipe failures (FAIL) and to calculate water supply reliability (REL).  Based on the results of these tools, annual rehabilitation projects are selected and ranked (ARP tool). Information of network is further used for the estimation of long-term investments needs (LTP). The tools are operated jointly within the "CARE-W Manager", which also contains facilities for using pipe network databases, geographical information systems (GIS) and input/output routines. The results from using the procedures are presented by reports, in tables and graphically. Aimed at planning engineers, water utilities and municipalities and consultants working in the increasingly growing field of the planning of rehabilitation of water networks in cities.

In most network industries, new dynamics are leading to an unprecedented opening up to competition and private sector participation. With the development of a single European market, the in-stages liberalisation process of public utilities has spread to almost all sectors. However, the water supply and sanitation (WSS) sector is considered somehow different and it has been excluded until recently from the restructuring processes achieved in other sectors. Water and Liberalisation: European Water Scenarios presents a better understanding of the specific demands of the WSS sector. Covering the operators' strategies, the regulatory dynamics as well as their interactions on the evolution of the sector, it addresses the likelihood, the nature, and the forms the WSS sector may take in Europe in the foreseeable future. Adopting a neutral political stance, the book analyses the implications of alternative scenarios in economic, ecological, social, legal, and institutional terms. Key sections include: In depth introduction to the current situation in the WSS sector; The European water supply and sanitation markets; The institutional framework of the water supply and sanitation sector in the EU: a comparative analysis; Analysis of the EU explicit and implicit policies and approaches in the sector; Analysis of the strategies of the water operators in Europe scenarios on the evolution of the water sector in Europe; Economic, environmental, & social implications of the scenarios; Major implications per scenario.

CARE-S presents the result of an extensive EU project, Computer Aided Rehabilitation of Sewer and Storm Water Networks. The projects developed a complete management system for sewer and storm water assets, including methods and software. It comprises methods and models for the three levels necessary of management, namely the long-term planning, the project ranking and the technology selection. The results of a comprehensive testing of CARE-S in representative European cities are also included in the book. Long-term planning relies on state-of-the-art description, judgement of future service-life and available measurements, including CCTV. This information is handled in tools for Performance Indicators, network condition prediction and investment needs. Project ranking is conducted by an elimination system and includes analysis by tools for structural condition, hydraulic performance and customer requirements. The system identifies projects that can be included within actual budget limits. Selection of appropriate technologies relies on a comprehensive database for renovation and repair techniques and their properties, applied into the conditions of the single projects. The purpose of this book is to present a new generation management system of sewer and storm water assets. Due to ageing systems and increasing demands to these networks, and the complexity of systems and problems, advanced management systems are necessary to secure an optimal use of limited resources for repair, maintenance and renewal. In the future, management should be based on solid objective information given by computer programs and databases, and judged by professional management engineers. The market for modern urban water network management including software and consulting services is expected to increase substantially during the coming years. This is the first book to consider a complete management system for sewer and storm water assets. The book presents a system that will improve the cost-effectiveness of sewer and storm water assets by at least 10%. The book presents the methodology and software for modern maintenance and renewal of wastewater networks.

This project aims at the evaluation of eight various routes that potentially may allow wastewater treatment plants to produce less sludge (from 5% to 100%). It has been possible to define several routes that could be applied efficiently with knowledge of possible side-effects (risk management) and an estimation of associated costs (OPEX/CAPEX), which are quite comparable to those used in conventional sludge treatment and disposal.

This Report synthesizes the main results obtained throughout the ADVISOR research project ("Integrated Evaluation for Sustainable River Basin Governance") funded by the European Commission, under the - 'Energy, Environment and Sustainable Development' theme of the 5th Framework Research Programme. The aim of ADVISOR was to improve the understanding of evaluation processes as part of river basin planning and management and to provide a framework supported by a toolkit for the conduct of integrated and participatory evaluations. The project comprised four work-packages. Work Package 1 examined past water project or plan evaluation cases in five EU states and drew insights on the problems of past evaluation practices. Work Package 2 interpreted these past experiences from different analytical angles leading to a theory for an integrated evaluation process, emphasising issues of deliberation, multiple values, quality in the use of information and governance. Work Package 3 moved from theory to practice. Different tools which could contribute to integrated evaluation processes were tested in experimental case applications. These included scenario workshops, mediated modelling supported by a quality assurance protocol, social multi-criteria evaluation, cost-effectiveness analyses and monetary valuation. Work Package 4 aimed at transferring the experience and lessons learned during the ADVISOR project to policy makers, contributing especially to the implementation process of the Water Framework Directive. A guidance document for designing and implementing Integrated Deliberative Decision Processes (IDDP) was developed, detailing a step-by-step procedure to achieve integrated evaluations. The synthesis of the main results achieved throughout the ADVISOR project is presented in this report in three parts: Part A sets the stage for the role of integrated evaluations in river basin planning and management; Part B unfolds the set of relevant principles and tools developed in the project and Part C concludes with futures challenges for integrated evaluation processes.

Sewer systems constitute a very significant heritage in European cities. Their structural quality and functional efficiency are key parameters to guarantee the transfer of domestic and industrial wastewater to treatment plants without infiltration nor exfiltration. Infiltration of groundwater is particularly detrimental to treatment plant efficiency, while exfiltration of wastewater can lead to groundwater contamination. The European research project APUSS (Assessing infiltration and exfiltration on the Performance of Urban Sewer Systems) was devoted to sewer infiltration and exfiltration questions. It was structured in three main Work Areas dealing respectively with i) the development of new measurement methods based on tracer experiments and accounting for detailed uncertainty analyses, ii) the implementation of models and software tools to integrate structural and experimental data and to facilitate data display, operational management and decision-making processes and iii) the integration of economic and operational questions by means of cost estimation, economic evaluation, performance indicators and multi-criteria methods applied to investment/rehabilitation strategies. This final report describes the objectives, methods and main results for each Work Area. References to detailed methods, protocols, reports and tools are given in this final report which will be an invaluable source of information for all those concerned with the performance of urban sewer systems.

The European DayWater project has developed a prototype of an Adaptive Decision Support System (ADSS) related to urban stormwater pollution source control. The DayWater ADSS greatly facilitates decision-making for stormwater source control, which is currently impeded by the large number of stakeholders involved and by the necessary multidisciplinary knowledge. This book presents the results of this project, providing new insights into both technical and management issues. The main objectives of its technical chapters are pollution source control modelling, risk and impact assessment, and evaluation and comparison of best management practices. It also covers management aspects, such as the analysis of the decision-making processes in stormwater source control, at a European scale, and stormwater management strategies in general. The combination of scientific-technical and socio-managerial knowledge, with the strong cooperation of numerous end-users, reflects the innovative character of this book which includes actual applications of the ADSS prototype in significant case studies. DayWater: an Adaptive Decision Support System for Urban Stormwater Management contains 26 chapters collectively prepared by DayWater scientific partners and end-users associated with this European Research and Development project. It includes: A general presentation of the DayWater Adaptive Decision Support System (ADSS) structure and operation modesA detailed description of the major components of this ADSS prototypeThe assessment of its components in significant case studies in France, Germany and SwedenThe proceedings of the International Conference on Decision Support Systems for Integrated Urban Water Management, held in Paris on 3-4 November 2005. The book presents the ADSS prototype including a combination of freely accessible on-line databases, guidance documents, “road maps” and modelling or multi-criteria analysis tools.  As demonstrated in several significant case studies the challenge for stormwater managers is to make the benefits of urban stormwater management visible to society, resulting in active co-operation of a diversity of stakeholders. Only then, will sustainable management succeed. DayWater: an Adaptive Decision Support System for Urban Stormwater Management advances this cause of sustainable urban management through Urban stormwater management, and makes achievable (by means of risk and vulnerability tools which are included) the goal of integrated urban water management (IUWM).

Integrated Deliberative Decision Processes for Water Resources Planning and Evaluation is part of the ADVISOR ("Integrated Evaluation for Sustainable River Basin Governance") research project funded by the EC, under the "Energy, Environment and Sustainable Development" theme of the 5th Framework Research Programme. The aim of ADVISOR is to improve the understanding of evaluation processes as part of river basin planning and management and to provide a framework supported by a toolkit for the conduct of integrated and participatory evaluations. Integrated Deliberative Decision Processes for Water Resources Planning and Evaluation is Work Package 4 of the project and helps to transfer the experience and lessons learned during the ADVISOR project to policy makers, contributing especially to the implementation process of the Water Framework Directive. An Integrated Deliberative Decision Process (IDDP) is proposed to be adopted as the platform to achieve integrated evaluations and this book explains and provides a step-by-step guidance on how to design and run such a process. Integrated Deliberative Decision Processes for Water Resources Planning and Evaluation has been written especially for policy makers, with theoretical reflections also provided where these bear importance to practical implementation.

The Adaptiveness of IWRM provides new insights and knowledge on the challenges and solutions that current water management faces in a situation of complexity and uncertainty. Drawing on the available results from a wide range of European research projects under several framework programmes, the book provides an overview of the state of the art in European research on Integrated Water Resources Management on the topics of Participation, Transboundary regimes, Economics, Vulnerability, Climate change, Advanced monitoring, Spatial planning, and the Social dimensions of water management. The achievements of EU research projects are considered in view of the extent to which IWRM responds to the current complexity and uncertainty water management is facing. These achievements are positioned in a wider context of worldwide developments in the respective topics which account for the future challenges. From this, the book concludes with the required focus of European research in the near future and promotes the concept of Adaptive Water Management as the preferred direction for the development of IWRM.     The book presents the achievements of European IWRM research on a range of water management topics and offers conclusions and recommendations for research foci that will be invaluable to water managers, policy-makers and academic researchers working in the field of IWRM.

This book (the research outcome of the EU-INCO FP6 research project Jayhun: Interstate Water Resource Risk Management: Towards a Sustainable Future for the AralBasin) focuses on and discusses the results of research done on the risk assessment levels associated with relevant regional variables in the Aral Basin and develops a strategy for an improved management of the region’s water resources. The book provides current and reliable information on the rate of glacial retreat in Central Asian and the implications for future water resources in the region. The impact of global changes on annual precipitation is assessed. The rates of reservoir siltation are established by hydrographic surveys, and analyses of wastage and effectiveness of water usage in the large irrigation massifs are conducted. Water resources models are used to analyse existing and newly generated data. These are calibrated with existing data and subsequently used for simulating various possible future scenarios. The book thereby provides a risk analysis for water resources management in the Aral Basin and identifies sustainable options for improved management of the region’s water resources.

About 4000 medical compounds are being used in the drugs applied today. It is estimated that worldwide consumption of active compounds amounts to some 100,000 tons or more per year. Consequently, there is a need to highlight the most important questions and issues related to presence of pharmaceuticals in the environment. Pharmaceuticals in the Environment: current knowledge and need assessment to reduce presence and impact brings together results of previous and on-going EU projects with published data from both governmental sources and scientific literature and manufacturers’ data on production and usage of pharmaceuticals. This book puts together the current knowledge and emphasises questions that deserve attention such as: What is the spectrum of most relevant pharmaceutical products (PPs) for the aquatic environment? Which indicators for supporting environmental managers, health authorities? What is the efficiency of urban and industrial sewage treatment plants over a year? What is the fate and behaviour of PPs in sewage treatment plants? If receiving waters are used for potable water supplies, does the presence of these compounds represent a potential hazard to human health? Could we solve some problems by environmental or cleaner technologies? What regulatory approaches, incentives, prevention actions can be implemented in order to lower PPs concentration in the environment? Does a European practical guidance can be developed? Can the impacts of PPs on the environment be reduced through the use of eco-pharmaco-stewardship approaches including the use of clean synthesis, classification and labelling, and better communication of methods of 'good practice'? How can we better monitor the environmental impact of a pharmaceutical once it has received a marketing authorisation?

Reverse osmosis is the dominant technology in water desalination. However, some critical issues remain open: improvement of water quality, enhancement of the recovery factor, reduction of the unit water cost, minimizing the brine disposal impact. This book aims to solve these problems with an innovative approach based on the integration of different membrane operations in pre-treatment and post-treatment stages. Membrane-Based Desalination: An Integrated Approach (acronym MEDINA) has been a three year project funded by the European Commission within the 6th Framework Program. The project team has developed a work programme aiming to improve the current design and operation practices of membrane systems used for water desalination, trying to solve or, at least, to decrease the critical issues of sea and brackish water desalination systems. In the book, the main results achieved in the nine Work Packages constituting the project will be described, and dismissed by the leaders of the various WPs. The following areas are explored in the book: the development of advanced analytical methods for feed water characterization, appropriate fouling indicators and prediction tools, procedures and protocols at full-scale desalination facilities; the identification of optimal seawater pre-treatment strategies by designing advanced hybrid membrane processes (submerged hollow fibre filtration/reaction, adsorption/ion exchange/ozonation) and comparison with conventional methods; the optimisation of RO membrane module configuration, cleaning strategies, reduction of scaling potential by NF; the development of strategies aiming to approach the concept of Zero Liquid Discharge (increasing the water recovery factor up to 95% by using Membrane Distillation - MD; bringing concentrates to solids by Membrane Crystallization or Wind Intensified Enhanced Evaporation) and to reduce the brine disposal environmental impact and cost; increase the sustainability of desalination process by reducing energy consumption (evaluation of MD, demonstration of a new energy recovery device for SWRO installations) and use of renewable energy (wind and solar). Colour figures (PDF, 6MB)   Visit the IWA WaterWiki to read and share material related to this title: http://www.iwawaterwiki.org/xwiki/bin/view/Articles/WaterdesalinationandEuropeanresearch

The strategy and methodology for improved IWRM project, (STRIVER) has developed interdisciplinary methods to assess and implement IWRM. Based on the development of a multidisciplinary knowledge base assessment in all case studies (policy, social and natural sciences) and an early stage development of IWRM conceptual framework, this book investigates IWRM in the four selected twinned catchments covering six countries in Europe and Asia. Twinning activities based on a problem-based approach have been performed in four case river basins: Tunga Bahdra (2 states in India), Sesan (Vietnam/Cambodia), Glomma (Norway), Tejo/Tagus (Spain/Portugal). The problems covered are water regimes in transboundary regulated rivers; environmental flow; land and water use interaction; and pollution under the IWRM framework. The research used sub-basins of each river basin in all cases to allow more detailed studies and easier integration of all stakeholders, for transferability purposes. Integrating Water Resources Management develops guidelines for interdisciplinary methods to assess and implement IWRM assesses the transferability of case study results enhances the dialogue between decision-makers, stakeholders and scientists disseminates data and information to stakeholders to promote participatory planning and integrated decision-making, taking adequate account of the rights of poor people and gender roles More information about the book can be found on the Water Wiki in an article written by the author here: http://www.iwawaterwiki.org/xwiki/bin/view/Articles/IntegratingWaterResourcesManagement

Innovative and Integrated Technologies for the Treatment of Industrial Wastewater deals with advanced technological solutions for the treatment of industrial wastewater such as aerobic granular biomass based systems, advanced oxidation processes integrated with biological treatments, membrane contactors and membrane chemical reactors. Wastewater from pharmaceutical, chemical and food industries as well as landfill leachates are specifically considered as representative of major problems encountered when treating industrial streams. The economic and environmental sustainability of the above solutions are also reported in the book and compared with the alternatives currently available in the market by life cycle assessment (LCA) and life cycle costing (LCC) methodologies. The implementation of the considered solutions at large scale could support and enhance the competitiveness of different industrial sectors, including the water technology sector, in the global market. Innovative and Integrated Technologies for the Treatment of Industrial Wastewater also makes a contribution towards defining: new concepts, processes and technologies in wastewater treatment with potential benefits for the stable quality of effluents, energy and operational costs saving, and the protection of the environment new sets of advanced standards for wastewater treatment new methodologies for the definition of wastewater treatment needs and framework conditions new information supporting development and implementation of water legislation.

The adoption of the Urban Waste Water Treatment Directive requires sewage sludge to be subsequently treated and the Sewage Sludge Directive regulates the uses and properties of stabilised sludge for being either recycled or disposed. Both directives drive specific actions in two complementary ways. Reduction, Modification and Valorisation of Sludge aims at developing strategies for the disposal and reuse of waste sludge. It aims to develop several processes for reducing both amount and toxicity of sludge, with simultaneous transformation into green energy vectors such as methane or hydrogen. Mesophilic and mainly thermophilic and autothermophilic conditions are explored as classical alternatives for sludge stabilisation, assuring sanitary conditions of the treated sludge. Valuable materials are obtained from sludge, such as activated carbons, which are used in conventional adsorption processes and in innovative advanced oxidation processes. Guidelines are provided for technology selection in agreement with the geographic, economic and technical characteristics of the sewage plants, demonstration of the feasibility of new applications for the sewage sludge, manufacturing of activated carbon from sludge sewage as innovative recycling of sludge waste, and a deep understanding of the methods involved.   Visit the IWA WaterWiki to read and share material related to this title: http://www.iwawaterwiki.org/xwiki/bin/view/Articles/GLOBALATLASOFEXCRETAWASTEWATERSLUDGEANDBIOSOLIDSMANAGEMENTMOVINGFORWARDTHESUSTAINABLEANDWELCOMEUSESOFAGLOBALRESOURCE

Many EU cities are experiencing increasing problems with their water pipeline infrastructure. The cost of replacing these old, worn-out systems, if left to deteriorate beyond repair, is astronomical and clearly beyond the resources of many communities. Replacement, however, is not the only choice as many of these systems can be rehabilitated at 30 to 70 percent of the cost of replacement. Accordingly, resources are now increasingly being allocated to address pipeline rehabilitation management issues. Due to the emphasis on sustainable management, risk-based approaches for the rehabilitation management of the water supply network need to be developed. Rehabilitation decisions should be based, interalia, on inspection and evaluation of the pipeline conditions. Yet, utilities cannot locate a number of their old pipes and current inspection technologies typically do not provide the needed detailed information on pipeline damage. The objectives of this book are to describe the research work carried out in the framework of WATERPIPE project aiming: To develop a novel, high-resolution imaging ground penetrating radar for the detection of pipes, leaks and damages and the imaging of the damaged region and evaluate it at a test siteTo produce an integrated system that will contain the equipment in "1" and a Decision Support System (DSS) for the rehabilitation management of the underground water pipelines that will use input from the inspections to assess, probabilistically, the time-dependent leakage and structural reliability of the pipelines and a risk-based methodology for rehabilitation decisions that considers the overall risk, including financial, social and environmental criteriaTo field test the equipment and the DSS
