Urban Water III is the proceedings of the 3rd International Conference on the Design, Construction, Maintenance, Monitoring and Control of Urban Water Systems. The conference reconvened following its success in 2012 and in 2014, when it was held in the Algarve, Portugal. These proceedings deal with two main subjects: water supply systems and urban drainage. Water distribution networks often suffer substantial losses which indicate energy and treatment waste. Sewer systems are under relentless pressure due to urbanisation and climate change, and the environmental impact caused by urban drainage overflows is related to both water quantity and water quality. Most architects and town planners are aware of the importance of the interaction between urban water cycles and city planning and landscaping. Specialised computer tools are needed to manage all of these aspects and are required to respond to the increased complexity of urban water systems. Topics such as contamination and pollution discharges in urban water bodies, as well as the monitoring of water recycling systems are currently receiving a great deal of attention from researchers and professional engineers working in the water industry. Other related topics include: Leakage and losses; Modelling and experimentation; Safety and security of water systems; Maintenance and repairs; Surface water and groundwater sources; Reservoirs; Network design; Waste water treatment and disposal; Combined sewer networks; Flood control; Storage tanks; Environmental impact; Domestic and industrial waste water issues. In addition to the above, the conference discusses legal and regulatory aspects, along with more technical problems.

Flooding is a global phenomenon that claims numerous lives worldwide each year. Apart from the physical damage to buildings, contents and loss of life, which are the most obvious, impacts of floods upon households and other more indirect losses are often overlooked. These indirect and intangible impacts are generally associated with disruption to normal life and longer-term health issues. Flooding represents a major barrier to the alleviation of poverty in many parts of the developing world, where vulnerable communities are often exposed to sudden and life-threatening events. As our cities continue to expand, their urban infrastructures need to be re-evaluated and adapted to new requirements related to the increase in population and the growing areas under urbanization. Topics such as contamination and pollution discharges in urban water bodies, as well as the monitoring of water recycling systems are currently receiving a great deal of attention from researchers and professional engineers working in the water industry. The papers contained in this volume cover these problems and deals with two main urban water topics: water supply networks and urban drainage. Originating from the 7th International Conference on Flood and Urban Water Management, the included research works include innovative solutions that can help bring about multiple benefits toward achieving integrated flood risk and urban water management strategies and policy.

Research works were presented at the 8th International Conference on Flood and Urban Water Management with the aim of developing innovative solutions that can help bring about multiple benefits toward achieving integrated flood risk and urban water management strategies and policy. The papers resulting from these works form this book. Flooding is a global phenomenon that claims numerous lives worldwide each year. When flooding occurs in urban areas, it can cause substantial damage to property as well as threatening human life. In addition, many more people must endure the homelessness, upset and disruption that are left in the wake of floods. The increased frequency of flooding in the last few years, coupled with climate change predictions and urban development, suggest that these impacts are set to worsen in the future. How we respond and importantly, adapt to these challenges is key to developing our long term resilience at the property, community and city scale. As our cities continue to expand, their urban infrastructures need to be re-evaluated and adapted to new requirements related to the increase in population and the growing areas under urbanization. We also need to consider more nature-based interventions to the management of flood risk, including the adoption of more catchment-based approaches. These are now being recognised as being more sustainable and also able to achieve wider benefits to the environment and society as a whole. Water supply systems and urban drainage are also increasingly important due to this expansion. Topics such as contamination and pollution discharges in urban water bodies, as well as the monitoring of water recycling systems are currently receiving a great deal of attention from researchers and professional engineers working in the water industry. Mitigating losses from water distribution networks and effective, efficient and energy-saving management are key goals for optimising performance and reducing negative impacts. Sewer systems are under constant pressure due to growing urbanization and climate change, and the environmental impact caused by urban drainage overflows is related to both water quantity and water quality. This book is aimed at researchers, academics and practitioners involved in research and development activities across a wide range of technical and management topics related to urban water and flooding and its impacts on communities, property and people.

Developing an improved understanding of emerging flood risk management and urban water management was the goal set for research presented at the 6th International Conference on Flood and Urban Water Management, held in A Coruña, Spain. The published papers look to solve various challenges in this field by drawing on the expertise of numerous disciplines and considering a range of responses.

Rainwater tank systems have been widely adopted across the world to provide a safe local source of water in underdeveloped rural areas, a substitution for mains water for non potable end uses in water stressed urban areas, as well as providing flooding control in monsoonal climates such as Korea, or combined sewer systems such as Germany. The importance of these systems in cities has grown, as water managers seek to provide a range of decentralised solutions to supply constraints of current water supply systems, whilst reducing the impact of urban development on the natural environment, and increasing resilience to the impacts of climate change. Rainwater tank systems are now often implemented under integrated urban water management (IUWM) and water sensitive urban design (WSUD) philosophies, which take a holistic view of the urban water cycle. Rainwater Tank Systems for Urban Water Supply is based on a comprehensive, multi-million dollar research program that was undertaken in South East Queensland (SEQ) Australia in response to the Millennium drought when the water supply level in the regions drinking water dams dropped to 17% in July 2007 and the area came close to running out of water. In particular, the book provides insights and detailed analysis of design, modelling, implementation, operation, energy usage, economics, management, health risk, social perceptions and implications for water quality/quantity of roof water runoff. The approaches and methodologies included in Rainwater Tank Systems for Urban Water Supply inform and validate research programs, and provide insights on the expected performance and potential pitfalls of the adoption of rainwater tanks systems including: actual harvested yield and resulting mains water savings, optimal sizing for rainwater storages and roof collection systems, expected water quality and implications for managing public health risks, modelling tools available for decision support, operation and management approaches of a decentralised asset at the household scale and community acceptance. The book is suitable for use at undergraduate and post graduate levels and is of particular interest to water professionals across the globe, who are involved in the strategic water planning for a town, city or a region. It is a valuable resource for developers, civil designers, water planners, architects and plumbers seeking to implement sustainable water servicing approaches for residential, industrial and commercial developments.

Water control is essential to Japan, as more than half of its invested capital is concentrated in elevations under sea level and the majority of the island nation is exceptionally vulnerable to flooding. To avoid potential crisis, the Japanese have developed exceptionally innovative water management practices. Offering the unique perspective of Dutch engineers, considered the world’s most progressive urban water experts, this volume provide a detailed look at how Japan has developed its modern water system. It looks at the system of Tokyo city, discusses river management practices and urban flood control throughout the country, and considers the impact that these innovations have had on delta regions.

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

This handbook provides a comprehensive, state-of-the-art overview of urban water governance. Of the many growing challenges presented by rapid urbanization, water governance is a critical one and while urban water governance is now regarded as a critical field of research, the literature is fragmented. For the first time, this handbook brings together urban water governance research, containing interdisciplinary contributions from established and emerging scholars, practitioners, and policymakers. It addresses the key questions of how urban water governance works, how is it shaped, and what the impacts are. The handbook's structure offers a progressive entry into the complexity of urban water governance. Starting with technical dimensions, the handbook addresses supply and demand, wastewater, and sanitation. It then considers regulation and economic factors, examining water utilities and services. Political processes, and the actors involved, are addressed and the handbook finishes with a part focusing on governance and sustainability, where chapters address critically important topics such as access to water, water safety, and water security. This handbook is essential reading for students, scholars, and professionals interested in urban water governance, urban studies, and water resource management and sustainability more broadly.
