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.

"The WHO Guidelines for Drinking-water Quality recommends the application of a comprehensive risk assessment and risk management approach called Water Safety Plans (WSPs) to most effectively ensure the safety of drinking-water supplies. The WSP approach is systematic, comprehensive, cost-effective and appropriate in a wide range of circumstances and thus are an important tool for small community water supplies. This manual is designed to engage, empower and guide communities in the WSP development and implementation process. Guidance is provided on how to develop and implement a WSP through six achievable tasks. By following the WSP approach as described in this manual, small communities can improve the management of their drinking-water systems to achieve incremental and sustainable improvements in their drinking-water quality."--Publisher's description.

Every year, thousands of deaths due to diarrhea, cholera, typhoid and other gastrointestinal diseases have been attributed to poor water, sanitation and hygiene not just in this region but globally. Diarrheal diseases could be avoided if water suppliers would ensure the safety of drinking water from source to consumer. Guided by the national drinking water regulations, the health-based targets of maximum allowable concentration for microbiological, chemical, physical and radiological parameters in drinking water could be achieved through the application of the multiple barrier approach to risk management in water supply. This is the overall principle and goal of water safety plans. This Workbook is intended to be used for training within the Region emphasizing a systematic and preventive risk-based approach to avoid drinking water contamination towards improvement of public health. The strategy is to use multiple barriers so that if one barrier fails, the water stays safe. The intended users are water supply practitioners at all levels especially water quality managers, operators, regulators, assessors, academics, consultants, NGOs, and international organizations.

The factors affecting the presence and growth of micro-organisms in piped networks are reviewed in this book, as are the practices of water supply organisations that can directly or indirectly influence their presence and growth. The information and conclusions are intended for policy makers and those responsible for formulating "Water Safety Plans" for the supply of drinking-water. It is also relevant to engineers and scientists who are responsible for water supply planning, operations and monitoring. The review shows that there are often public health reasons for adopting a more proactive approach to many of the traditional practices used in designing, operating and maintaining distribution networks, and to modifying the composition of the water that is fed into the network. Contents include the following topics: The microbiology of piped distribution systems and public health Composition of treated waters to minimise potential for microbiological changes Design and operation of distribution networks. Planned maintenance and survey of distribution systems Precautions during construction and repairs Small animals in drinking water distribution systems Risk management for distribution systems
