This book documents state of the art research designed to compliment the advances being made in the global water quality sector. Book 1 provides guidelines for implementing WSPs in developing countries (see book 2 1843800829)

This book documents state of the art research designed to compliment the advances being made in the global water quality sector. Book 2 provides further detail on supporting programmes.

In 2004, the WHO Guidelines for Drinking Water Quality recommended that water suppliers develop and implement "Water Safety Plans" (WSPs) in order to systematically assess and manage risks. Since this time, governments and regulators, water suppliers and practitioners have increasingly embraced this approach, but they have also requested further guidance. This much-anticipated workbook answers this call by describing how to develop and implement a WSP in clear and practical terms. Stepwise advice is provided through 11 learning modules, each representing a key step in the WSP development and implementation process: 1. Assemble the WSP team; 2. Describe the water supply system; 3. Identify hazards and hazardous events and assess the risks; 4. Determine and validate control measures, reassess and prioritise the risks; 5. Develop, implement and maintain an improvement/upgrade plan; 6. Define monitoring of the control measures; 7. Verify the effectiveness of the WSP; 8. Prepare management procedures; 9. Develop supporting programmes; 10. Plan and carry out periodic review of the WSP; 11. Revise the WSP following an incident ; Every Module is divided into three sections: 'Overview', 'Examples and Tools', and 'Case studies'. The overview section provides a brief introduction to the Module, including why it is important and how it fits into the overall WSP development and implementation process. It outlines key activities that should be carried out, lists typical challenges that may be encountered, and summarizes the essential outputs to be produced. The examples and tools section provides resources which could be adapted to support the development and implementation of WSPs. These resources include example tables and checklists, template forms, diagrams, or practical tips to help a WSP team address specific challenges. These are often example outputs and methodologies adapted from recent WSP experiences. Each Module concludes with case studies so the reader can benefit from lessons-learned from real-life experiences. They are intended to make WSP concepts more concrete and to help readers anticipate issues and challenges that may arise. The descriptions were drawn from WSP initiatives in Australia, the Latin American and the Caribbean region (LAC), and the United Kingdom.

Water risks and security are a major global hazard in the 21st century and it is essential that water professionals have a solid grounding in the principles of preventative risk management. This second edition of the key textbook, Risk Management for Water and Wastewater Utilities, extends beyond first principles and examines the practicalities of resilience and vulnerability assessment, strategic risk appraisal and the interconnectedness of water utility risks in a networked infrastructure. It provides an up-dated overview of tools and techniques for risk management in the context of the heightened expectations for sound risk governance that are being made of all water and wastewater utilities. Risk Management for Water and Wastewater Utilities provides a valuable starting point for newly appointed risk managers in the utility sector and offers MSc level self-paced study with self-assessment questions and abbreviated answers, key learning points, case studies and worked examples.

This book gives decision makers, health professionals and analysts a comprehensive view of the arguments and challenges associated with establishing the value of drinking-water interventions. The experts who have contributed to this publication provide guidance on assessing the benefits from improving access to safe drinking water and from reducing the burden of water-related diseases. They show how to compare the value of these benefits to the costs of the interventions, with special reference to small-scale drinking water systems.

This book has been written specifically for practitioners involved in the operation, maintenance and management of piped water distribution systems in urban areas of developing countries. These practitioners include engineers, planners, managers, and water professionals involved in the monitoring, control and rehabilitation of water distribution networks. The book explains in detail how to evaluate the risk of deterioration of the water distribution network of a water supply system. It begins with the conceptualization of risk evaluation and its three different components (hazard, vulnerability and risk). The book further elaborates on each of these three components, explains the methodologies used to estimate the components, and presents the background to the mathematical models. Finally, the book explains how these components are integrated to form a GIS-based decision support system for risk evaluation. The book is designed to help practitioners understand the concept of risk evaluation and supports the manual of the IRA-WDS software, a GIS-based decision support system for risk evaluation.
