The IWA Performance Indicator System for water services is now recognized as a worldwide reference. Since it first appearance in 2000, the system has been widely quoted, adapted and used in a large number of projects both for internal performance assessment and metric benchmarking. Water professionals have benefited from a coherent and flexible system, with precise and detailed definitions that in many cases have become a standard. The system has proven to be adaptable and it has been used in very different contexts for diverse purposes. The Performance Indicators System can be used in any organization regardless of its size, nature (public, private, etc.) or degree of complexity and development. The second edition of Performance Indicators for Water Supply Services represents a further improvement of the original manual. It contains a reviewed and consolidated version of the indicators, resulting from the real needs of water companies worldwide that were expressed during the extensive field testing of the original system. The indicators now properly cover bulk distribution and the needs of developing countries, and all definitions have been thoroughly revised. The confidence grading scheme has been simplified and the procedure to assess the results- uncertainty has been significantly enhanced. In addition to the updated contents of the original edition, a large part of the manual is now devoted to the practical application of the system. Complete with simplified step-by-step implementation procedures and case studies, the manual provides guidelines on how to adapt the IWA concepts and indicators to specific contexts and objectives. The manual includes a new version of the software Sigma Lite incorporating all the new developments and an improved graphical user interface. This new edition of Performance Indicators for Water Supply Services will be an invaluable reference source for all those concerned with managing the performance of the water supply industry, including those in the water utilities as well as regulators, policy-makers and financial agencies.

This book presents comparative analyses and accounts of the institutional changes that have occurred to the local level delivery of public utilities and personal social services in countries across Europe. Guided by a common conceptual frame and written by leading country experts, the book pursues a “developmental” approach to consider how the public/municipal sector-centred institutionalization of service delivery (climaxing in the 1970s) developed through its New Public Management-inspired and European Union market liberalization-driven restructuring of the 1980s and early 1990s. The book also discusses the most recent phase since the late 1990s, which has been marked by further marketization and privatization of service delivery on the one hand, and some return to public sector provision (“remunicipalization”) on the other. By comprising some 20 European countries, including Central East European “transformation” countries as well as the “sovereign debt”-stricken countries of Southern Europe, the chapters of this volume cover a much broader cross section of countries than other recent publications on the same subject.

Provides a highly illustrated guide for designers, installers and contractors working on hot and cold water supplies. The book takes account of the 1999 Water Regulations and British Standard BS 6700. The new edition takes account of the latest requirements of the Building Regulations and features a new section on sprinkler systems.

As global climate change threatens to change radically both the political and physical climate with regard to water issues, so a reassessment of some of the fundamental principles of international water law is emerging. One of the most important principles being reassessed is the sovereign equality of states. This volume brings together more than thirty leading international water and legal specialists to explore the development and changing relationship between water, state sovereignty and international law. Offering fresh insights into one of the most pressing issues in global water policy, Sovereignty and International Water Law will form an essential reference for water professionals, legal specialists and policy makers alike.

This book provides the first comprehensive overview of the most important water-related issues that centre on Italy, analysed from several disciplinary perspectives – such as hydrology, economics, law, sociology, environmental sciences and policy studies – in order to promote full understanding of the challenges the country is facing and the ways it could best tackle them. Despite the misconception that Italy is a water-scarce country, is in fact quite rich in water resources. Such resources, however, are unevenly distributed over the Italian territory. Italy’s northern regions rely on quite an abundant quantity of freshwater, whereas in the southern area water endowment is limited. Moreover, climatic differences between North and South contribute to widen the divide. This disparity has notable consequences of socio-economic character, some of which, in turn, feed back into the environmental conditions of Italian regions: pollution, floods, landslides and droughts are among the problems affecting the country. There are numerous features of water use and consumption that distinguish Italy from other comparable countries, such as the significant role played by agriculture (a water-intensive activity), a lead position in the consumption of bottled water, lower-than-average prices of water and a far-from-optimal efficiency of waterworks. All such aspects, and many others, make Italy an essential case study.
