Safe drinking-water management must consider drinking-water quality, acceptability and quantity ...in the context of public health protection. In this manual, the term “safety” encompasses these three elements. Although the principles in this manual can be broadly applied to all types of drinking-water supplies, the guidance is primarily intended for piped water supplies that are professionally managed (by a water supplier or equivalent management entity).The guidance may be applied to existing drinking-water supplies, or adapted for water supplies that are in the planning stage before construction.

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 opportun...ities 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.

The Guidelines for drinking-water quality: small water supplies have been developed to address the needs and opportunities associated with small su...pplies to facilitate progressive improvement towards safe and sustainable drinking-water services for all. These Guidelines are based on the principal recommendation in the World Health Organization’s Guidelines for drinking-water quality, and they provide guidance on applying that recommendation to small water supplies in particular. These Guidelines aim to help governments and practitioners improve the safety of drinking-water delivered through small supplies.

The public health community has tried for decades to show, through evidence-based research, that safe water, sanitation, and hygiene (WASH) and clean cooking fuels that reduce ho...usehold air pollution are essential to safeguard health and save lives in low-income and middle-income countries. In the past 40 decades, there have been many innovations in the development of low-cost and efficacious technologies for WASH and household air pollution, but many of these technologies have been associated with disappointing health outcomes, often because low-income households have either not adopted, or inconsistently adopted, these technologies.

When setting national drinking-water quality regulations and standards, many countries consider the WHO Guidelines for drinking-...ribute-to-highlight medbox">water quality (GDWQ). To better understand the extent to which the GDWQ are used and reflected in these standards, this global review summarizes information from 104 countries and territories on values specified in national drinking-water quality standards for aesthetic, chemical, microbiological and radiological parameters.
The information provided will support regulatory agencies and other key stakeholders to access and compare data when setting or revising national drinking-water quality regulations and standards.

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-wat...er 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.

The training is targeted at all professionals involved in the management of drinking-water safety. The handbook is divided into three parts:
• Part 1 – Overview of the training approach, tr...aining structure and mode of training assessment
• Part 2 – Module learning material, which includes module objectives, delivery information, key points and exercises
• Part 3 – How the material can be adapted to different utility contexts

Step-by-step risk management guidance for drinking-water supplies in small communities.
The WHO/IWA document A practical guide to auditing water safety plans provides guidance on developing and implementing a WSP auditing scheme, covering such topics as the aim and role of auditing, auditor training and certification, audit crit...eria, audit timing and frequency and audit reporting. The guidance document includes examples, tips, tools and case studies from more than a dozen low-, middle-, and high-income countries, and it serves as a practical resource for policy makers, government bodies responsible for drinking-water regulation or surveillance and water suppliers implementing WSPs.

Storage tanks are required for collection of ..."attribute-to-highlight medbox">water from springs or water produced from continuous flow water treatment systems, e.g. from upflow clarifiers or slow sand filters. There should be sufficient storage volume to store all water produced overnight, as this is unlikely to be collected by users during the night. Storage tanks also have secondary functions such as ensuring a constant water supply to treatment processes, providing a level of treatment by settlement of larger suspended solids and maintaining pressure in distribution systems

The guide is presented in two parts:
Part 1. Principles of Operational Monitoring: Describes the key principles of operational monitoring, alongside the types of operational monitoring that may be performed and the information required within an OMP.
Part 2. Operational Monitorin...g Plan Development: Describes the stepwise development of an OMP for a water supply system, including the source, water treatment, intermediate storage, distribution and household. For illustration purposes, practical guidance is provided using a specimen water supply system considered to be representative of a conventional small- to medium-sized supply in a lower resource setting. This template may be used to develop system-specific OMPs for individual water supply systems.
