Book excerpt: Well-run water utilities play an important role in ending poverty and boosting shared prosperity. Consumers need reliable access to high quality and affordable water and sanitation services. To deliver these basic services efficiently and effectively requires high-performing utilities that are able to respond to urban growth, to connect with the poor, and to improve wastewater disposal practices. The International Benchmarking Network for Water and Sanitation Utilities of the World Bank's Water and Sanitation Program (IBNET) has been involved in water sector monitoring since 1997. IBNET works to improve utility performance through enhanced sharing of critical knowledge and expertise, to expand access to comparative data among utilities globally, and to promote best practice among water supply and sanitation providers. By delivering access to technical and financial information on utility performance, IBNET enables key stakeholders to do their jobs better: utility managers and employees can identify areas for improvement; governments can monitor and adjust sector policies and programs; regulators can ensure that customers get value; investors can identify viable markets and opportunities for creating value; and customer groups and NGOs can exercise 'voice' in an informed way. The IBNET Water Supply and Sanitation Blue Book 2014 summarizes the water sector status from 2006 to 2011. Since 2006, municipal water performance has improved despite accelerated urbanization and the impacts of triple crises (food, fuel, and financial). Overall coverage has increased and piped water and wastewater services became accessible to more people. An increasing number of utilities now actively handle the water billing, collection, and water management through metering. IBNET tools, such as data collection instruments and protocols, the IBNET database, and the IBNET tariff database, enable enhanced sharing of information on close to 4,500 utilities from more than 130 countries and territories.

Available in PDF, EPUB and Kindle. Book excerpt: Safe drinking water is paramount for the health and wellbeing of all human populations. Water is extracted from surface and groundwater sources and treated to comply with drinking water standards. The water is then circulated through the drinking water distribution system (DWDS). Within the DWDS, water quality can deteriorate due to microbiological growth, chemical reactions, interactions with ageing and deteriorating infrastructure, and through maintenance and repair activities. Some DWDS actions may serve to improve water quality; however, these can adversely impact the drinking water system and cause instances of poor water quality or disease outbreaks. We invited papers covering examinations of DWDS design and operational practices and their impact on water quality. We received papers based on practical research in real DWDS and laboratory test facilities. We also received papers on novel modelling approaches. A wide range of water quality aspects was gathered, including temperature, disinfection, bacterial communities and biofilm, (fecal) contamination and QMRA, and the effects of flushing and intermittent supply.

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

Available in PDF, EPUB and Kindle. Book excerpt: Global water crisis is a challenge to the security, political stability and environmental sustainability of developing nations and with climate, economically and politically, induces migrations also for the developed ones. Currently, the urban population is 54% with prospects that by the end of 2050 and 2100 66% and 80%, respectively, of the world's population will live in urban environment. Untreated water abstracted from polluted resources and destructed ecosystems as well as discharge of untreated waste water is the cause of health problems and death for millions around the globe. Competition for water is wide among agriculture, industry, power companies and recreational tourism as well as nature habitats. Climate changes are a major threat to the water resources. This book intends to provide the reader with a comprehensive overview of the current state of the art in integrated assessment of water resource management in the urbanizing world, which is a foundation to develop society with secure water availability, food market stability and ecosystem preservation.

Available in PDF, EPUB and Kindle. Book excerpt: Access to water is one of the most pressing global issues of the twenty-first century, particularly when set against the background of a rapidly growing global population. This book provides a cutting-edge, comprehensive overview of the challenges facing water governance and regulatory choices. The recently adopted Sustainable Development Goals set forward an ambitious agenda of providing universal access to good quality water supply and sanitation services within a financially constrained environment: however, the various peculiarities of each country regarding water governance makes it difficult to identify and implement the best practices and benchmarks. Drawing together empirical studies from countries around the world, the editors and contributors combine extensive data to review the individual challenges facing each country, from the supervision of autonomous regulatory bodies to the question of centralization and the influence of local utility companies. This pioneering and practical volume will be of interest and value not only to students and scholars of water governance, but also to practitioners and regulators.

Available in PDF, EPUB and Kindle. Book excerpt: The importance of small towns is gaining increased recognition as a result of two developments. The first development concerns the possible role of small towns in migration flows and urbanization. Development of small towns, in the form of improved basic services and other amenities, has been promoted in order to abate the impact of urbanization on large urban centres and to alleviate service provision pressures in major urban centers, whilst stimulating rural economies and eventually prompting social transformations. The second development concerns the targets set by the SDGs in 2015. SDG6 requires countries to ensure universal and equitable water services by 2030. This inclusive target requires that the water services needs of small towns are considered in the expansion of sustainable and equitable water services. This book aims to contribute to the study of water services in small towns by critically examining different approaches and experiences of water supply in small towns. It brings together empirical testimonies of how the implementation of reductionist models and the perseverance of certain principles underlying these models in the water sector have yielded suboptimal results. Much remains to be done before achieving universal service coverage in small towns is likely. In order to do that, we should start speaking of small towns as a category on their own and continue the work in elaborating further what these are and how they work. In Focus – a book series that showcases the latest accomplishments in water research. Each book focuses on a specialist area with papers from top experts in the field. It aims to be a vehicle for in-depth understanding and inspire further conversations in the sector.

Available in PDF, EPUB and Kindle. Book excerpt: This book comprises components associated with smart water which aims at the exploitation and building of more sustainable and technological water networks towards the water–energy nexus and system efficiency. The implementation of modeling frameworks for measuring the performance based on a set of relevant indicators and data applications and model interfaces provides better support for decisions towards greater sustainability and more flexible and safer solutions. The hydraulic, management, and structural models represent the most effective and viable way to predict the behavior of the water networks under a wide range of conditions of demand and system failures. The knowledge of reliable parameters is crucial to develop approach models and, therefore, positive decisions in real time to be implemented in smart water systems. On the other hand, the models of operation in real-time optimization allow us to extend decisions to smart water systems in order to improve the efficiency of the water network and ensure more reliable and flexible operations, maximizing cost, environmental, and social savings associated with losses or failures. The data obtained in real time instantly update the network model towards digital water models, showing the characteristic parameters of pumps, valves, pressures, and flows, as well as hours of operation towards the lowest operating costs, in order to meet the requirement objectives for an efficient system.
