Book excerpt: Concerns over the impacts of urban growth have prompted the development and adoption of water-demand management strategies. Water and energy savings from increasingly efficient technologies, diversified water sources, and water savings policies are typically quantified from an individual demand-side basis, but network-wide potential is not well studied. This paper studies the effects of residential demand profiles on the performance of urban water networks, in response to emerging demand management strategies. To assess the performance of three demand scenarios: 1) base, 2) conservation, and 3) load-shifting, hydraulic simulations were conducted. Four metrics of network performance are suggested to evaluate responses to scenarios: water loss, water age, energy loss, and peak flow. The results revealed network performance for energy and flow metrics improved under both conservation and load-shifting scenarios. However, these scenarios had either a negative or an insignificant impact on water age and losses throughout the network. The results indicate potential savings from these demand profiles cannot be fully realized without adjustments in network operation, and may come at a cost in terms of water quality. This works suggests an initial tool for evaluating network-wide effects of different demand management strategies.

Available in PDF, EPUB and Kindle. Book excerpt: The Special Issue on Advances in Modeling and Management of Urban Water Networks (UWNs) explores four important topics of research in the context of UWNs: asset management, modeling of demand and hydraulics, energy recovery, and pipe burst identification and leakage reduction. In the first topic, the multi-objective optimization of interventions on the network is presented to find trade-off solutions between costs and efficiency. In the second topic, methodologies are presented to simulate and predict demand and to simulate network behavior in emergency scenarios. In the third topic, a methodology is presented for the multi-objective optimization of pump-as-turbine (PAT) installation sites in transmission mains. In the fourth topic, methodologies for pipe burst identification and leakage reduction are presented. As for the urban drainage systems (UDSs), the two explored topics are asset management, with a system upgrade to reduce flooding, and modeling of flow and water quality, with analyses on the transition from surface to pressurized flow, impact of water use reduction on the operation of UDSs, and sediment transport in pressurized pipes. The Special Issue also includes one paper dealing with the hydraulic modeling of an urban river with a complex cross-section.

Available in PDF, EPUB and Kindle. Book excerpt: Climate change and increasing patterns of drought throughout the world are challenging the effectiveness of conventional water systems. A growing population in conjunction with more extreme weather events, threatens water supply infrastructure and increases uncertainty about how utilities will meet demand without sacrificing water quality. This issue has recently manifested in California, prompting utilities to invest in alternative water sources as a means of ensuring that water infrastructure is resilient to climate change scenarios. Decentralized wastewater treatment is a promising option for increasing the sustainability of water infrastructure as it spatially merges supply and demand, minimizing large conveyance requirements. Decentralization can also promote nutrient management and recovery as it enables the source separation of the different wastewater sources. Specifically closing the nitrogen loop, by capturing it and reusing it to generate valuable high-end products can potentially improve the efficiency of the system and create revenue streams. However, smaller decentralized water treatment units are potentially more energy intensive and costly than their centralized alternatives per unit of water treated. Due to these efficiency tradeoffs, planning tools and frameworks for holistically assessing decentralized water treatment systems need to be developed to optimally manage the new urban water supply paradigm. Better data management and data-driven decision support tools can provide valuable insight on the benefits and impacts of implementing future water systems. This research assesses the technical performance of emerging decentralized technologies and implementation scenarios for residential uses, by assessing the feasibility of integrating decentralized facilities in cities with existing wastewater infrastructure. This work aims to create algorithmic models that integrate the spatial design of a wastewater treatment and distribution network with a life-cycle assessment to determine the associated environmental impacts. This dissertation utilizes spatial modeling to contextually evaluate the implementation and distribution potential and uses a life-cycle assessment approach to provide an extensive analysis of all the life-cycle impacts. By incorporating environmental indicators and metrics, a planning support framework can be created to help guide the water industry towards smart investments for a less energy-intensive future. Specifically, this work will 1) investigate how spatial terrain variability, demographics and distribution affect the performance of decentralized water treatment systems, 2) analyze the major parameters that affect the energy intensity, cost and greenhouse gas emissions of these systems, 3) quantify the unit processes that mostly impact the prementioned metrics and 4) identify the optimal system scale for decentralized infrastructure implementation under various spatial and demographic conditions. The insights from this dissertation can help wastewater researchers and practitioners understand the complex relationships between the system scale and system performance. By evaluating the potential benefits and tradeoffs, this work can lead to management tools that will help transition away from traditional water management and create a water supply that (1) is resilient to changes in climate, (2) uses local water sources, and (3) leaves more water in natural ecosystems. This dissertation further adds to the growing body of literature on decentralized wastewater treatment assessing optimal scales, reuse potential, resource recovery and sewerage connections to investigate key factors affecting future implementation.

Available in PDF, EPUB and Kindle. Book excerpt: In the 21st Century, the world will see an unprecedented migration of people moving from rural to urban areas. With global demand for water projected to outstrip supply in the coming decades, cities will likely face water insecurity as a result of climate change and the various impacts of urbanisation. Traditionally, urban water managers have relied on large-scale, supply-side infrastructural projects to meet increased demands for water; however, these projects are environmentally, economically and politically costly. Urban Water Security argues that cities need to transition from supply-side to demand-side management to achieve urban water security. This book provides readers with a series of in-depth case studies of leading developed cities, of differing climates, incomes and lifestyles from around the world, that have used demand management tools to modify the attitudes and behaviour of water users in an attempt to achieve urban water security. Urban Water Security will be of particular interest to town and regional planners, water conservation managers and policymakers, international companies and organisations with large water footprints, environmental and water NGOs, researchers, graduate and undergraduate students.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Water scarcity is becoming increasingly familiar to us. Although access to water resources is an issue of global concern, arid climates are where necessity begets inventions that may serve as examples for action or prevention across a multitude of climate zones and geographies. In facing the prevalence of water scarcity across the globe, due to a mix of climatological and man-made factors, the question we must ask ourselves today is Water for What? Which approaches can landscape, urban and architectural designers take in order to apply their specific professional skills and means? What potential do available technologies and materials offer, and what methods and tools can be derived from social engagement? Based on five years of research, the preparation of and feedback on a traveling exhibition, as well as a major conference, the results of the Out of Water project are laid out here in a series of case studies and essays by international experts, including analytical drawings of both projected and implemented solutions.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Today there is increasing pressure on the water infrastructure and although unsustainable water extraction and wastewater handling can continue for a while, at some point water needs to be managed in a way that is sustainable in the long-term. We need to handle water utilities “smarter”. New and effective tools and technologies are becoming available at an affordable cost and these technologies are steadily changing water infrastructure options. The quality and robustness of sensors are increasing rapidly and their reliability makes the automatic handling of critical processes viable. Online and real-time control means safer and more effective operation. The combination of better sensors and new water treatment technologies is a strong enabler for decentralised and diversified water treatment. Plants can be run with a minimum of personnel attendance. In the future, thousands of sensors in the water utility cycle will handle all the complexity in an effective way. Smart Water Utilities: Complexity Made Simple provides a framework for Smart Water Utilities based on an M-A-D (Measurement-Analysis-Decision). This enables the organisation and implementation of “Smart” in a water utility by providing an overview of supporting technologies and methods. The book presents an introduction to methods and tools, providing a perspective of what can and could be achieved. It provides a toolbox for all water challenges and is essential reading for the Water Utility Manager, Engineer and Director and for Consultants, Designers and Researchers.
