Water meters are the cornerstone of commercial systems for water utilities throughout the world; revenue is directly derived from the, figures provided by meters. Despite this, little attention has been paid, in terms of selection, replacement period and return on investment, to the management and optimization of water meters. Integrated Water Meter Management is a comprehensive reference for engineers and managers alike, providing: in-depth technical information allowing the true nature and behaviour of meters to be understood; a comprehensive review and comparison of relevant global water meter technologies - a useful tool to help decide which water meter is best for your utility; discussion of key decisions concerning the use of water meters (when to replace them, which one to use, how to control their quality) from a managerial perspective. Integrated Water Meter Management is an invaluable resource for those involved in urban water management, including water utility managers, engineering technical staff, operations and maintenance specialists, meter-reading personnel and scientific researchers in this discipline.

A collection of articles by leading international experts on modeling and control of potable water distribution and sewerage collection systems, focusing on advances in sensors, instrumentation and communications technologies; assessment of sensor reliability, accuracy and fitness; data management including SCADA and GIS; system

Water utilities worldwide lose 128 billion cubic meters annually, causing annual monetary losses estimated at USD 40 billion. Most of these losses occur in developing countries (74%). This calls for rethinking the challenges facing water utilities in developing countries, foremost of which is the assessment of water losses in intermittent supply networks. Water loss assessment methods were originally developed in continuous supply systems, and their application in intermittently operated networks (in developing countries) is hindered by the widespread use of household water tanks and unauthorised consumption. This study provides an extensive review of existing methods and (software) tools for water loss assessment. In addition, several new methods were developed, which offer improved water loss assessment in intermittent supply. As the volume of water loss varies monthly and annually according to the amount of supplied water, this study proposes procedures to normalise the volume of water loss in order to enable water utilities to monitor and benchmark their performance on water loss management. The study also developed a novel method of estimating apparent losses using routine data of WWTP inflows, enabling future real-time monitoring of losses in networks. Different methods have also been suggested to estimate the unauthorised consumption in networks. This study found that minimum night flow analysis can still be applied in intermittent supply if an area of the network is supplied for several days. Furthermore, this study concluded that water meter performance is enhanced in intermittent supply conditions. However, continuous supply in the presence of float-valves significantly reduces the accuracy of water meters. Finally, this study provides guidance and highlights several knowledge gaps in order to improve the accuracy of water loss assessment in intermittent supply. Accurate assessment of water loss is a prerequisite for reliable leakage modelling and minimisation as well as planning for, and monitoring of water loss management in distribution networks.

The proceedings from The Water and Society Conference 2015 aim to encourage trans-disciplinary communication on issues related to the nature of water, and its use and exploitation by society. The papers within this book demonstrate the need to bridge the gap between the broad spectrum of socio-political sciences and humanistic disciplines and specialists in physical sciences, biology, environmental sciences and health. The Water and Society conference series which began 2011 comprise of issues such as the need for clean and inexpensive water by an increasing global population, and the growing demands of Agriculture and Industry. The book deals with the interaction between water and energy systems, as well as the more technical aspects of water resources management and quality, in the aim to help the policy makers put forward policies and legislation that will lead to improved solutions for all. Topics covered include: Water as a human right; Water quality; Water resources contamination; Water sanitation and health; Water and disaster management; Future water demands; Irrigation and desertification.

This thesis presents analysis of the status of IWRM implementation along with the challenges with regards to policy and institutional measures as well as the required basin information and management instruments. The research entailed a detailed analysis of water resources systems based on a case study from the Awash River Basin in Ethiopia, covering the historical and present state of the challenges and gaps in policies, institutional arrangements and management instruments. The status quo of practical water management, implications of plausible management alternatives in terms of their impact to future water availability, demand fulfilment, patterns of use, and sustainability of the environment were examined. Moreover, the interlinkages and dynamics between key water dependent resources sectors, broadly categorized into water, energy, food, and ecosystems (WEFE) was explored to identify key tradeoffs and synergies. This was deliberated as to improving the synchronization of sectoral plans and resources management programs, thereby fast-tracking the coordination process in IWRM. Overall, the research provides a clearer understanding of the system-wide problems, structural challenges and possible future consequences regarding the management and sustainability of the entire water resource system. Ultimately the purpose is to set in motion new strategies and mechanisms to improve the implementation of the currently applied IWRM framework in the context of the SDGs.

Water Management Challenges in Global Change contains the proceedings of the 9th Computing and Control for the Water Industry (CCWI2007) and the Sustainable Urban Water Management (SUWM2007) conferences. The rationale behind these conferences is to improve the management of urban water systems through the development of computerbased methods. Issues such as economic globalisation, climate changes and water shortages call for a new approach to water systems management, which addresses the relevant technical, social and economic aspects. This collection represents the views of academic and industrial experts from a number of countries, who provide technical solutions to current water management problems and present a vision for addressing the global questions. The themes underlying many of the contributions include energy and material savings, water savings and the integration of different aspects of water management. The papers are grouped into three themes covering water distribution systems, sustainable urban water management and modelling of wastewater treatment plants. The water distribution topics cover asset and information management, planning, monitoring and control, hydraulic modelling of steady state and transients, water quality and treatment, demand and leakage management, optimisation, design and decision support systems, as well as reliability and security of water distribution systems. The sustainable urban water management topics include urban drainage systems, water reuse, social aspects of water management and also selected facets of water resources and irrigation. Computer control of wastewater treatment plants has been seen as less advanced than that of clean water systems. To address this imbalance, this book presents a number of modelling techniques developed specifically for these plants. Water Management Challenges in Global Change will prove to be invaluable to water and environmental engineering researchers and academics; managers, engineers and planners; and postgraduate students.

This volume addresses the situation of water and wastewater management from a global angle, underpinned by selected case studies. Without doubt, water and wastewater management are among the greatest challenges of our century, and there is also no doubt that the challenges posed by climate change will become even greater. However, most efforts, especially in developing countries but also in the so-called developed countries, have been less than optimal or not optimal at all. In particular, there are still too many people who have to live without clean water and decent sanitation. Today, 2.2 billion people lack access to safely managed drinking water and wastewater, and 4.2 billion people lack safely managed sanitation services. The question, why this is so and why in many cases in developing countries, is discussed in this book among other urgent water and wastewater management issues. The publication of this book is the start of a book series that in more detail critically reviews, discusses, and analyzes the water and wastewater situation and management in different regions and countries worldwide.

Integrated urban water management relies on data allowing us to analyse, understand and predict the behaviour of the individual water cycle components and their interactions. The concomitant monitoring of the complex of urban water system elements makes it possible to grasp the entirety of relations among the various components of the urban water c
