Today’s urban water managers are faced with an unprecedented set of issues that call for a different approach to urban water management. These include the urgent changes needed to respond to climate change, population growth, growing resource constraints, and rapidly increasing global urbanization. Not only are these issues difficult to address, but they are facing us in an environment that is increasingly unpredictable and complex. Although innovative, new tools are now available to water professionals to address these challenges, solving the water problems of tomorrow cannot be done by the water professionals alone. Instead, the city of the future, whether in the developed or developing world, must integrate water management planning and operations with other city services to meet the needs of humans and the environment in a dramatically superior manner. Water Sensitive Cities has been developed from selected papers from 2009 Singapore Water Week “Planning for Sustainable Solutions” and also papers taken from other IWA events. It pulls together material that supports the water professionals’ need for useful and up-to-date material.

This book advocates a more thoughtful approach to urban water management. The approach involves reducing water consumption, harvesting rainwater, recycling rainwater and adopting Sustainable Drainage Systems (SuDS) where surface water is not sent straight to drains but is intercepted by features like green roofs, rain gardens, swales and ponds.Cities in particular need to change the existing linear model of water consumption and use to a more circular one in order to survive. The Water Sensitive City brings together the various specialised technical discussions that have been continuing for some time into a volume that is more accessible to designers (engineers and architects), urban planners and managers, and policymakers.

Approaches to Water Sensitive Urban Design: Potential, Design, Ecological Health, Economics, Policies and Community Perceptions covers all aspects on the implementation of sustainable storm water systems for urban and suburban areas whether they are labeled as WSUD, Low Impact Development (LID), Green Infrastructure (GI), Sustainable Urban Drainage Systems (SUDS) or the Sponge City Concept. These systems and approaches are becoming an integral part of developing water sensitive cities as they are considered very capable solutions in addressing issues relating to urbanization, climate change and heat island impacts in dealing with storm water issues. The book is based on research conducted in Australia and around the world, bringing in perspectives in an ecosystems approach, a water quality approach, and a sewer based approach to stormwater, all of which are uniquely covered in this single resource.

Building water-wise cities is a pressing need nowadays in both developed and developing countries. This is mainly due to the limitation of the available water resources and aging infrastructure to meet the needs of adapting to social and environmental changes and for urban liveability. This is the first book to provide comprehensive insights into theoretical, systematic, and engineering aspects of water-wise cities with a broad coverage of global issues. The book aims to (1) provide a theoretical framework of water-wise cities and associated sustainable water systems including key concepts and principles, (2) provide a brand-new thinking on the design and management of sustainable urban water systems of various scales towards a paradigm shift under the resource and environmental constraints, and (3) provide a technological perspective with successful case studies of technology selection, integration, and optimization on the “fit-for-purpose” basis.

This book contributes to current debates regarding purposive transitions to sustainable cities, providing an accessible but critical exploration of sustainability transitions in urban settings. We have now entered the urban century, which is not without its own challenges, as discussed in the preceding book of this series. Urbanization is accompanied by a myriad of complex and overlapping environmental, social and governance challenges – which increasingly call into question conventional, market-based responses and simple top-down government interventions. Faced with these challenges, urban practitioners and scholars alike are interested in promoting purposive transitions to sustainable cities. The chapters in this volume contribute to the growing body of literature on city-scale transformative change, which seeks to address a lack of consideration for spatial and urban governance dimensions in sustainability transitions studies, and expand on the basis established in the preceding book. Drawing on a range of perspectives and written by leading Australian and international urban researchers, the chapters explore contemporary cases from Australia and locate them within the international context. Australia is on the one hand representative of many OECD countries, while on the other possessing a number of unique attributes that may serve to highlight issues and potentials internationally. Australia is a highly urbanized country and because of the federal political structure and the large distances, the five largest state-capital cities have a relatively high degree of autonomy in governance – even dominating the rest of their respective states and rural hinterlands to a certain extent. This context suggests that Australian cases can provide interesting “test-tube” perspectives on processes relevant to urban sustainability transitions worldwide. This volume presents an extensive overview of theories, concepts, approaches and practical examples informed by sustainability transitions thinking, offering a unique resource for all urban practitioners and scholars who want to understand and transition to sustainable urban futures.

How can design processes assist in understanding the underlying and hybrid nature of water systems in our urban environments so that we can better prepare for the densification of cities and the impact of climate change? This book captures propositions and speculations around this question through design studies undertaken in three Australian cities: Melbourne's low-lying swampy areas, Brisbane's flooding river valley and Perth's deep groundwater network. Each of these cities has its own set of challenges around water, based on their particular natural environmental conditions and the radical modifications over 200 years that have fundamentally changed the way that water moves. The ambitious schemes of the past - dams, drains, canals, sewers, reservoirs, lakes, aqueducts - made room for the 'progress' of the late nineteenth and twentieth centuries. Now in the twenty-first century we need new ambitions where urban environments can adapt to the unpredictability of water through its extremes of dry and wet conditions. The design responses in this book contribute to such an aim by understanding the past, present and possible future conditions of local sites, and using this knowledge to create multi-purposed, alternative design scenarios towards a water-sensitive city. There is a confluence between available contemporary development land and problematic water sites. Many of the places in which contemporary development is occurring were not part of the originally planned city, and were leftover places that were never really suitable for development because of their water issues; these include high groundwater areas in Perth, low-lying flood-prone post-industrial lands in Melbourne, and urbanised flooding zones of Brisbane. These areas, now in central focus to accommodate large-scale city development for growing urban populations, demand new ways of thinking and building.

During recent years, techniques and legislation for decentralized storm-water management have advanced all over the world. However, decentralized storm-water management systems are still under-utilized and acceptance among citizens and professionals is still lacking. Yet management of this issue will be essential for the sustainable development of cities in the future. Thus acceptance of the systems must be improved. The main question that needs to be answered is how can sustainable storm-water management be integrated with urban design in order to create safe, liveable, sustainable, and attractive cities? This manual, developed by the Hafen City University of Hamburg, provides an overview of a Water Sensitive Urban Design approach and creates principles for a successful strategy focused on the topics: Water Sensitivity, Aesthetics, Functionality, Usability, Public Perception and Acceptance, as well as Integrative Planning. It furthermore presents an international selection of case studies ranging from small scale (site level) up to large scale (city level), demonstrating the WSUD principles in the context of the temperate climates.
