Book excerpt: Water and Wastewater companies operating all around the world have faced rising asset management and replacement costs, often to levels that are financially unsustainable. Management of investment needs, while meeting regulatory and other goals, has required: A better understanding of what customers demand from the services they pay for, and the extent to which they are willing to pay for improvements or be compensated for a reduction in performance Development of models to predict asset failure and to identify and concentrate investment on critical assets Improved management systems Improved accounting for costs and benefits and their incorporation within an appropriate cost-benefit framework Incorporation of risk management techniques Utilisation of advanced maintenance techniques including new rehabilitation failure detection technologies Enhancements in pipeline materials, technologies and laying techniques. These papers developed from LESAM 2007 for inclusion in Strategic Asset Management of Water Supply and Wastewater Infrastructures are focused on the techniques, technologies and management approaches aiming at optimising the investment in infrastructure while achieving demanded customer service standards, and they provide an opportunity to gain access to the latest discussion and developments at the leading-edge in this field. This book will be essential reading for utility operators and managers, regulators and consultants.
Book Synopsis Assessing Infiltration and Exfiltration on the Performance of Urban Sewer Systems by : Bryan Ellis
Download or read book Assessing Infiltration and Exfiltration on the Performance of Urban Sewer Systems written by Bryan Ellis and published by IWA Publishing. This book was released on 2010-02-10 with total page 193 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book Synopsis Urban Hydroinformatics by : Roland K. Price
Download or read book Urban Hydroinformatics written by Roland K. Price and published by IWA Publishing. This book was released on 2011 with total page 553 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is an introduction to hydroinformatics applied to urban water management. It shows how to make the best use of information and communication technologies for manipulating information to manage water in the urban environment. The book covers the acquisition and analysis of data from urban water systems to instantiate mathematical models or calculations, which describe identified physical processes. The models are operated within prescribed management procedures to inform decision makers, who are responsible to recognized stakeholders. The application is to the major components of the urban water environment, namely water supply, treatment and distribution, wastewater and stormwater collection, treatment and impact on receiving waters, and groundwater and urban flooding. Urban Hydroinformatics pays particular attention to modeling, decision support through procedures, economics and management, and implementation in both developed and developing countries. The book is written with post-graduates, researchers and practicing engineers who are involved in urban water management and want to improve the scope and reliability of their systems.
Book Synopsis Deterioration and Optimal Rehabilitation Modelling for Urban Water Distribution Systems by : Yi Zhou
Download or read book Deterioration and Optimal Rehabilitation Modelling for Urban Water Distribution Systems written by Yi Zhou and published by CRC Press. This book was released on 2018-05-03 with total page 349 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pipe failures in water distribution systems can have a serious impact and hence it’s important to maintain the condition and integrity of the distribution system. This book presents a whole-life cost optimisation model for the rehabilitation of water distribution systems. It combines a pipe breakage number prediction model with a pipe criticality assessment model, which enables the creation of a well-constructed and more tightly constrained optimisation model. The pipe breakage number prediction model combines information on the physical characteristics of the pipes with historical information on breakage and failure rates. A weighted multiple nonlinear regression analysis is applied to describe the condition of different pipe groups. The criticality assessment model combines a pipe’s condition with its hydraulic significance through a modified TOPSIS. This model enables the optimisation to focus its efforts on those important pipes. The whole life cost optimal rehabilitation model is a multiple-objective and multiple-stage model, which provides a suite of rehabilitation decisions that minimise the whole life cost while maximising its long-term performance. The optimisation model is solved using a modified NSGA-II. The utility of the developed models is that it allows decision makers to prioritize their rehabilitation strategy in a proactive and cost-effective manner.
Book Synopsis Combining Green-Blue-Grey Infrastructure for Flood Mitigation and Enhancement of Co-Benfits by : Alida I Alves Beloqui
Download or read book Combining Green-Blue-Grey Infrastructure for Flood Mitigation and Enhancement of Co-Benfits written by Alida I Alves Beloqui and published by CRC Press. This book was released on 2020-03-12 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: An increment of urban flood risk in many areas around the globe is expected, accentuated due to climate change and urbanisation. Thus, appropriate flood risk management is crucial. Conventional approaches focus on grey infrastructure, which frequently do not address the root causes of risk. A change of paradigm is needed to develop effective adaptation strategies. Green-blue infrastructure (GBI) is a central concept to achieve adaptation to climate change. Its main strength is the ability to deliver multiple benefits. Although strong evidence exists demonstrating that GBI is a sustainable solution to reduce flooding, its adoption is still slow. Therefore, the objective of this research is to help decision-makers to adopt adaptation strategies to cope with flood risk while achieving other benefits. This study provides a framework which introduces co-benefits into decision-making for stormwater infrastructure planning. Besides, the multiple benefits are quantified and their impact on helping GBI implementation are evaluated. Finally, the effects of including co-benefits on the selection of flood mitigation strategies and the trade-offs among cost and benefits are assessed. This work contributes to enhance planning processes for flood mitigation combining green-blue-grey measures. It provides tools and knowledge to facilitate holistic decision-making, in order to ensure safe and liveable urban spaces for current and future conditions.

Book Synopsis Structures and Infrastructure Systems by : Dan M. Frangopol
Download or read book Structures and Infrastructure Systems written by Dan M. Frangopol and published by Routledge. This book was released on 2019-12-18 with total page 871 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our knowledge to model, design, analyse, maintain, manage and predict the life-cycle performance of infrastructure systems is continually growing. However, the complexity of these systems continues to increase and an integrated approach is necessary to understand the effect of technological, environmental, economic, social, and political interactions on the life-cycle performance of engineering infrastructure. In order to accomplish this, methods have to be developed to systematically analyse structure and infrastructure systems, and models have to be formulated for evaluating and comparing the risks and benefits associated with various alternatives. Civil engineers must maximize the life-cycle benefits of these systems to serve the needs of our society by selecting the best balance of the safety, economy, resilience and sustainability requirements despite imperfect information and knowledge. Within the context of this book, the necessary concepts are introduced and illustrated with applications to civil and marine structures. This book is intended for an audience of researchers and practitioners world‐wide with a background in civil and marine engineering, as well as people working in infrastructure maintenance, management, cost and optimization analysis. The chapters originally published as articles in Structure and Infrastructure Engineering.

Book Synopsis Advances in Modeling and Management of Urban Water Networks by : Alberto Campisano
Download or read book Advances in Modeling and Management of Urban Water Networks written by Alberto Campisano and published by MDPI. This book was released on 2021-01-06 with total page 290 pages. 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.
Download or read book CARE-S written by Sveinung Saegrov and published by IWA Publishing. This book was released on 2006-03-31 with total page 161 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book Synopsis The Common Good and Environmental Governance for the Support of Life by : Laura Westra
Download or read book The Common Good and Environmental Governance for the Support of Life written by Laura Westra and published by Cambridge Scholars Publishing. This book was released on 2016-08-17 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ongoing environmental crisis has given rise to grave concerns everywhere, and a number of authors have approached this topic from various disciplines and points of view, proposing different strategies to address and correct the situation. A major problem, however, is presented by the role and possible efficiency of existing legal regimes, most of which do not consider seriously the ecological problems that are the basis of most of the global problems that beset us. In 2015, Italy hosted the 2015 Expo of Milano, an important fair that attempted to address some of these major issues, primarily the availability of safe food and water, and the legal regimes that govern their distribution. The conference that resulted in this volume took place at the University of Parma, an old university in a city roughly one hour away. This volume discusses a variety of environmental and ecological issues from the standpoint of existing legal instruments, with a primary focus on the necessity for ecologically-oriented governance, in order to mitigate and redress a situation that – at present – supports multiple human rights violations.
