Wasser ist eine globale Ressource für heutige Gesellschaften – Wasser war eine globale Ressource vormoderner Gesellschaften. Die manigfaltigen unterschiedlicher Wassersysteme für Prozesse der Urbanisierung und das urbane Leben in der Antike und dem Mittelalter ist bislang kaum erforscht. Die zahlreichen Beiträge dieses Bandes fragen nach der grundlegenden kulturellen Bedeutung von Wasser ( bzw. power of water) in der Stadt und Wasser für die Stadt aus unterschiedlichen Perspektiven. Symbolische, ästhetische oder kultische Aspekte werden ebenso thematisiert wie die Rolle von Wasser in Politik, Gesellschaft oder Wirtschaft und dem alltäglichen Handeln, aber auch in Stadtplanungsprozessen oder städtischen Teilräumen. Nicht zuletzt stellen die Gefahren von verschmutzten Wasser oder Überschwemmungen die städtische Gesellschaft vor Herausforderungen. Die Beiträge diesen Band lenken den Blick auf die komplexen und vielfältigen Beziehungen zwischen Wasser und Menschen. Das Sammelwerk präsentiert die Ergebnisse einer internationalen Tagung in Kiel 2018. Es wendet sich gleichermaßen an Leser aus den altertumskundlichen wie mediävistischen Fächern und darüberhinaus an alle Interessierten, die sich über die Vielfalt von Wassersystemen im Stadtraum der Antike und des Mittelalters informieren möchten.
Focusing primarily on understanding the steady-state hydraulics that form the basis of hydraulic design and computer modelling applied in water distribution, Introduction to Urban Water Distribution elaborates the general principles and practices of water distribution in a straightforward way. The workshop problems and design exercise develop a tem
This book examines the role played by business in urban water governance by analyzing the evolution of the global private water sector along with four public-private partnerships in Mexico and the U.S. The local nature of water services often hides the global developments behind the rise of transnational water corporations, which have gone from being local operators to becoming dynamic and powerful actors within an interconnected transnational space for water. This book focuses on the French groups Veolia and Suez, two of the most prominent private actors in global water governance, and the development and adaptation strategies of both companies in the cities of Aguascalientes, Mexico City, Atlanta, and Milwaukee over the past 30 years. Drawing on over 100 interviews conducted with corporate executives, public authorities, and local users of water services, this book moves beyond the simplistic dichotomy of the public-private debate and develops a theoretical framework that analyzes the economic and political power wielded by transnational business actors in global water governance. Not only does the book explain how Veolia and Suez strategically mobilize resources at difference scales in order to expand their global operations, but it also provides a nuanced picture of how state regulation remains of central importance to understanding the dynamics and evolution of the global water sector. Students and scholars interested in business and the environment, including public-private partnerships, business management and transnational corporations, and water governance, will find this book of great interest as will professionals and policymakers working in these fields.
Urban water security is crucial for achieving sustainable development, peace, and human health and well-being. Framing urban water security is challenging due to the complexity and uncertainty of its definition and assessment framework. Several studies have assessed water security in widely divergent ways by granting priority indicators equal weight without considering or adapting to local conditions. This dissertation develops a new urban water security definition and assessment framework applicable to water scarce cities, with a focus on Madaba, Jordan. It takes a novel and systematic approach to assessing urban water security and culminates in integrated urban water security index (IUWSI) as a diagnostic tool and guide management actions. The dissertation suggests a new working definition of urban water security based on the United Nations (UN) Sustainable Development Goal 6.1 on safe drinking water for all and the human rights on water and sanitation as follows: The dynamic capacity of water systems and stakeholders to safeguard sustainable and equitable access to water of adequate quantity and acceptable quality that is continuously, physically and legally available at an affordable cost for sustaining livelihoods, human well-being and socioeconomic development, ensuring protection against waterborne pollution and water-related disasters, and for preserving ecosystems in a climate of peace and political stability. This proposed definition captures issues at the urban level of technical, environmental and socioeconomic indicators that emphasize credibility, legitimacy and salience. The assessment framework establishes a criteria hierarchy, consisting of four main dimensions to achieve urban water security: drinking water and human well-being, ecosystem, climate change and water-related hazards and socioeconomic aspects (together, DECS). The framework enables the analysis of relationships and trade-offs between urbanization, water security and DECS indicators. The dissertation also provides a structured analysis to understand how urban water is managed in intermittent water supply system, by conducting a water balance analysis after quantifying the components of water losses in Madaba’s water distribution network. The findings showed that Madaba's non-revenue water (NRW) amounted to annual loss of about 3.5 million m3, corresponding to financial losses of 2.8 million USD to the utility, of which 1.7 million USD is the cost of real losses. The dissertation provided an intervention strategy for strengthening infrastructure resilience and reducing leakage via the infrastructure, repair, economic, awareness and pressure (IREAP) framework. The IREAP framework provides a robust strategy to shift intermittent water supply (IWS) into continuous water supply. The IUWSI highlighted the state of water security in Madaba, Jordan and identified the means of implementation to move towards achieving urban water security based on the priorities for Madaba. The drinking water and human wellbeing dimension was the most important priority, receiving a weight of 66.22%, followed by ecosystem (17.15%), socioeconomic aspects (10.18%), and climate change and water-related hazards (6.45%) dimensions. The IUWSI indicated that the urban water security in Madaba is reasonable with a score of 2.5/5 and can meet the minimum requirements in several dimensions, but nonetheless, it has many loopholes to cover. Gaps are clear in the climate change and water-related hazards, and socioeconomic dimensions with scores of 1.6/5 and 2.237/5 respectively. Additionally, specific shortcomings are found in indicators such as water availability, reliability, diversity, and public health. The IUWSI framework assists with a rational and evidence-based decision-making process, which is important for enhancing water resource management in water-scarce cities
Water is an essential element in the future of cities. It shapes cities’ locations, form, ecology, prosperity and health. The changing nature of urbanisation, climate change, water scarcity, environmental values, globalisation and social justice mean that the models of provision of water services and infrastructure that have dominated for the past two centuries are increasingly infeasible. Conventional arrangements for understanding and managing water in cities are being subverted by a range of natural, technological, political, economic and social changes. The prognosis for water in cities remains unclear, and multiple visions and discourses are emerging to fill the space left by the certainty of nineteenth century urban water planning and engineering. This book documents a sample of those different trajectories, in terms of water transformations, option, services and politics. Water is a key element shaping urban form, economies and lifestyles, part of the ongoing transformation of cities. Cities are faced with a range of technical and policy options for future water systems. Water is an essential urban service, but models of provision remain highly contested with different visions for ownership of infrastructure, the scale of provision, and the level of service demanded by users. Water is a contentious political issue in the future of cities, serving different urban interests as power and water seem to flow in the same direction. Cities in Africa, Asia, Australia, Europe and South America provide case studies and emerging water challenges and responses. Comparison across different contexts demonstrates how the particular and the universal intersect in complex ways to generate new trajectories for urban water.
Introduction to Urban Water Distribution comprises the core training material used in the Master of Science programme in Urban Water and Sanitation at IHE Delft Institute for Water Education. Participants in this programme are professionals working in the water and sanitation sector from over forty, predominantly developing, countries from all parts of the world. Outside this diverse audience, the most appropriate readers are those who know little or nothing about the subject. However, experts dealing with advanced problems can also use it as a refresher of their knowledge, as well as the teachers in this field may like to use some of the contents in their educational programmes. The general focus in the book is on understanding the steady-state hydraulics that forms the basis of hydraulic design and computer modelling applied in water distribution. The main purpose of the workshop problems and three computer exercises is to develop a temporal and spatial perception of the main hydraulic parameters in the system for given layout and demand scenarios. Furthermore, the book contains a detailed discussion on water demand, which is a fundamental element of any network analysis, and general principles of network construction, operation and maintenance. The book includes nearly 700 illustrations and the accompanying electronic materials contain all the spreadsheet applications and the network model files used in solving the workshop problems and computer exercises. This book is the second volume of the Introduction to Urban Water Distribution, 2nd Edition set.
