Book Description
A sanitary inspection is a simple, on-site evaluation (traditionally using a checklist) to help identify and support the management of priority risk factors that may lead to contamination of a drinking-water supply. Sanitary inspections are a well-established and widely-applied practice. They can support water safety planning, and in some contexts, may be a simplified alternative to water safety plans. This publication presents the World Health Organization’s (WHO’s) sanitary inspection packages. These packages update the sanitary inspection forms in WHO’s 1997 Guidelines for drinking-water quality. Volume 3: surveillance and control of community supplies. With more than 25 years of practical experience with the application of sanitary inspections, these packages have been developed from a comprehensive evidence review and established good practices. Each package includes a sanitary inspection form, supported by technical guidance and management advice to help ensure the ongoing safe management of small water supplies. These new tools support proactive risk management and drinking-water quality surveillance across a broad range of water delivery scenarios, and can be applied by health authorities, surveillance agencies, water suppliers, and other stakeholders. As such, they are a valuable practical tool to help implement the recommendations in WHO’s 2024 Guidelines for drinking-water quality: small water supplies.

Book Description
Small drinking-water supplies commonly experience operational, managerial, technical and resourcing challenges that impact their ability to deliver safe and reliable services. The needs and opportunities associated with these supplies therefore warrant explicit consideration in policies and regulations. These Guidelines, specifically tailored to small water supplies, build on over 60 years of guidance by the World Health Organization (WHO) on drinking-water quality and safety. They focus on establishing drinking-water quality regulations and standards that are health based and context appropriate; on proactively managing risks through water safety planning and sanitary inspections; and on carrying out independent surveillance. The guidance is intended primarily for decision-makers at national and subnational levels with responsibility for developing regulatory frameworks and support programmes related to these activities. Other stakeholders involved in water service provision will also benefit from the guidance in this document. Designed to be practical and accessible, these Guidelines offer clear guidance that is rooted in the principle of progressive improvement. State-of-the-art recommendations and implementation guidance are provided, drawn from a comprehensive evidence review and established good practices. Additionally, case examples are provided from countries and areas around the world to demonstrate how the guidance in this publication has been implemented in practice in a wide variety of contexts. Together with WHO’s 2024 Sanitary inspection packages – a supporting tool for the Guidelines for drinking-water quality: small water supplies, these Guidelines update and supersede WHO’s 1997 Guidelines for drinking-water quality. Volume 3: surveillance and control of community supplies. Key changes to this updated publication include a greater focus on preventive risk management and a broader range of small water supplies covered, including those managed by households, communities and professional entities.

Book Description
Sanitation inspections are short, standardized checklists to assess risks at or near sanitation facilities and to recommend actions to protect public health. This document provides tools and examples for applying sanitation inspections in various contexts, including regulatory reporting, household surveys to monitor sanitation progress, and local evaluations of systems sustainability—particularly following community-led total sanitation initiatives - to identify risks in toilet facilities built during these programmes and inform necessary upgrades to meet safety standards.

Book Description
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.

Book Description
This is the third edition of the WHO's guidelines which are used by countries worldwide to set standards for the regulation of drinking water quality and effective approaches to water safety management. This revised edition has been updated to take account of recent developments in risk assessment and management. Topics discussed include: a framework for drinking water safety and discussion of the roles and responsibilities of different stakeholders, such as national regulators, water suppliers and independent surveillance agencies; guidance on microbial safety of drinking water through safety plans; new scientific information on chemicals, waterborne pathogens and individual chemical hazards of actual or potential concern. It also considers the application of the guidelines in specific circumstances, such as in emergencies and disasters, and to specific applications, such as bottled water. It also contains information on over 130 documents which substantiate or explain the content of the Guidelines, and on good practice guidance in achieving drinking-water safety.

Book Description
The brand new manual provides step-by-step guidance to determine revenue requirements, analyze rates, develop a financial plan, and design a better rate structure -- even with limited resources and data. Written for small water systems (defined as serving a population of up to 10,000) it focuses on the unique attributes of small systems as related to financial planning and rate design, with the understanding that most data is contained in the current customer billing system, and merely needs to be massaged. With details plus a sample case study, it helps develop a rate structure that emphasizes simplicity and ease of billing, while at the same time recognizes cost recovery and equitability. Also covered are communications with the public, which is integral to a successful rate restructuring, regulatory approval, system development funding, and rate phase-in.
