The public water supply, urban wastewater and urban waste management services are essential to the well-being of citizens, public health and economic activities. These are generally provided under natural or legal monopoly, so there is no incentive for utilities to search for greater efficiency and effectiveness and as such there is an increasing prevalence of such risks for users. For these reasons, society can significantly benefit from the existence of regulatory intervention capable of introducing greater balance in the relationship between utilities and their users. The Regulation of Water and Waste Services: An Integrated Approach (Rita-Ersar) presents a practical integrated regulatory approach to these water and waste services. This approach is called the ARIT-ERSAR model and it is capable of contributing to the promotion of access by citizens to these services that is tending towards the universal. These services are provided with suitable quality by utilities at socially acceptable prices and with an acceptable level of risk. This approach consists of a regulation model with two major areas of intervention: structural regulation of the sector and regulation of the performance of the utilities. The components of structural regulation are contributions to organisation, legislation, information and sectoral capacity building. The performance regulation of utilities consists of legal and contractual regulation, economic regulation, quality of service regulation, drinking water quality regulation and user interface regulation.

This book, published in collaboration with ERSAR, presents a unique account of governance and regulatory methods used by different countries, states and municipalities that will help regulators and governments all over the world to improve their regulatory approaches. It is the first book to compile such an amount of data about regulatory processes of a wide number of countries from the five continents. It discusses how the characteristics of water and wastewater services call for regulation and how different countries apply distinct regulatory methods. By showing 18 country case-studies, the book offers an interesting perspective as the regulatory models adopted vary immensely depending on geographical location, nature and strength of institutions and governments, political ideology, features and level of development of the countries. In addition, it provides examples of best practices that may be important for policy-makers to enhance the regulatory processes adopted in each country. It looks closely at rules imposed by state and local governments concerning regulatory issues and how they are being applied. Regulation of Water and Wastewater Services covers the fundamental and practical concepts and issues regarding the regulation of water and wastewater services. It describes and compares the regulatory methods adopted in several countries and provides a global overview on regulation. There is detailed coverage of topics such as quality of service regulation, economic regulation and public service obligations. This book is suitable for regulators, academic researchers and students, consultants, operators and managers, policy-makers and other stakeholders.

In the quest to reduce costs and improve the efficiency of water and wastewater services, many communities in the United States are exploring the potential advantages of privatization of those services. Unlike other utility services, local governments have generally assumed responsibility for providing water services. Privatization of such services can include the outright sale of system assets, or various forms of public-private partnershipsâ€"from the simple provision of supplies and services, to private design construction and operation of treatment plants and distribution systems. Many factors are contributing to the growing interest in the privatization of water services. Higher operating costs, more stringent federal water quality and waste effluent standards, greater customer demands for quality and reliability, and an aging water delivery and wastewater collection and treatment infrastructure are all challenging municipalities that may be short of funds or technical capabilities. For municipalities with limited capacities to meet these challenges, privatization can be a viable alternative. Privatization of Water Services evaluates the fiscal and policy implications of privatization, scenarios in which privatization works best, and the efficiencies that may be gained by contracting with private water utilities.

This is a compilation of topics that are at the forefront of many technical advances and practices in air and water control. These include air pollution control, water pollution control, water treatment, wastewater treatment, industrial waste treatment and small scale wastewater treatment.

Conclusions

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.

Water Consumption, Tariffs and Regulation aims to provide a statistical overview about water abstraction, consumption, tariffs and data on sewage and wastewater treatment at an international level. It is mainly based on the statistical information provided by IWA Specialist Group on Statistics and Economics. The book is structured in three main parts. Part I presents tables and figures relative to water consumption and sanitation status and focuses on water abstraction, water delivered, water consumption and the evolution of sewer connection and wastewater treatment. Part II focuses on the analysis of water tariffs by investigating the structure of water tariffs by analysing the importance of the variable and fixed charge. It presents drinking water tariffs and illustrates the relationship between tariffs and GDP and also the size of the cities. Finally, charges in wastewater are dealt with country by country. Part III analyses the main aspects relative to water regulation and describes the importance of private operators in the management of the water cycle. Information relative to the principles used to fix drinking water prices is presented with an assessment of access to public water services.

This report presents the third OECD review of Portugal’s environmental policy performance. It covers greening growth, environmental policies, international co-operation, climate change, waste management, and nature and biodiversity.
