French version. This document describes the WSP implementation process in New Caledonia (French territory in the Pacific Ocean) for 13 municipalities that started in 2008. It describes the risk assessment and management tools used, the benefits achieved, the challenges and solutions to those challenges and the overall lessons learned.

Presents the WSP for Spanish Town, Jamaica, which may provide an example approach for WSP development for WSP community at an early stage of WSP development

This case study provides an example of where a water supplier in France has established a system to collect consumer acceptability data via a group of volunteers. It provides one particular approach to the collection of opinions on the taste and odour of water supplied.

Small-scale systems are an important component of water supply in the WHO European Region, and Water Safety Plans (WSPs) are regarded the most effective approach to ensuring continuous provision of safe drinking-water.

The above is a short promotional video on WSPs in the WHO European Region.

Provides guidance for those responsible for managing water supply systems in buildings on applying the WSP approach to improve risk management and ensure water safety is maintained within the building.

This document provides guidance for managing water supplies in buildings where people may drink water; use water for food preparation; wash, shower, swim or use water for other recreational activities; or be exposed to aerosols produced by water-using devices, such as cooling towers. These uses occur in a variety of buildings, such as hospitals, schools, child and aged care, medical and dental facilities, hotels, apartment blocks, sport centres, commercial buildings and transport terminals.

This document is a technical paper following the "Spanish town Jamaica Case study". It describes the lessons learned from the development of the Water Safety Plan for the Spanish town water supply system in Jamaica.

The aim of this manual is to provide guidance on conducting a household survey as part of a Water Safety Plan for organized piped water supply systems in resource-limited settings. A household survey can help researchers to understand the fate of water from the time it reaches the home to the point of consumption. This survey contributes to Module 2 (System Assessment) of the Water Safety Plan, upon which the subsequent steps of hazard identification, consideration of control measures, and development of corrective actions, monitoring, and verification plans are based. Thus, the survey provides valuable information for the WSP team as the team goes through the process of system evaluation and implementation of changes resulting from the Water Safety Plan. Specific examples intended to guide the planner in designing the survey are provided in the appendices. A summary checklist for survey planning and completion is provided as Appendix A.

Rapid gravity filters are used extensively in many waterworks across the world where they provide a critical part of the water purification process. This document summarises the basic functions and operation of such filters and identifies possible risks to water quality which need to be assessed and managed as part of a treatment water safety plan.

Da Nang Water Supply Company (DAWACO) and Manila Water Company, Inc. (Manila Water) engaged in a water operator partnership (WOP) to help DAWACO meet World Health Organization (WHO) standards for water quality in their pipe network. Through the partnership, 20,000 residents received improved access to water, and DAWACO increased staff capacity to scale up similar improvements in the remainder of DAWACO’s service area.

This document sets out information which allows water suppliers and others to work together to minimise the risk of backsiophange (that is, the reverse flow condition created by a difference in water pressures that causes water and associated contaminants to flow back into drinking-water distribution pipes).

This case study provides the progress and lessons learned form the implementation of the Pacific Drinking Water Safety Plan programme.

This case study provides an example of where a water supplier in New Zealand operates a Service Centre to respond quickly to customer complaints and assesses levels of consumer acceptability through analysis of complaint data and questionnaires.

La quatrième édition des Lignes directrices de l'OMS pour la qualité de l'eau potable s'appuie sur plus de 50 ans d'orientations sur la qualité de l'eau potable qui font autorité en matière de mesures de santé publique lorsqu’il s’agit de mettre en place des réglementations et des normes nationales pour garantir la sécurité de l'eau.

C'est le produit de révisions significatives pour clarifier les recommandations et apporter des moyens de les mettre en œuvre en sachant identifier les dangers, gérer les risques en adoptant des indicateurs sanitaires, des plans de sécurité des eaux de captation et un système de surveillance indépendant.

Le premier addendum met à jour cette quatrième édition, apporte de nouveaux éléments de preuve et des explications supplémentaires pour mieux comprendre les directives et les mettre en œuvre.

Ces lignes directrices s’adressent principalement aux responsables de la réglementation dans le domaine de l’eau et de la santé, aux décideurs et à leurs conseillers, et ont pour objectif d’aider lors de la mise au point de normes nationales. Elles sont aussi utilisées, ainsi que les documents associés, par comme source d’informations sur la qualité et l’hygiène de l’eau et sur les stratégies de gestion efficaces.

Before implementation of a WSP it is important to clearly identify the expected benefits and the associated costs both of which could be significant. This will help secure the support of senior management, ensure that sufficient resources are made available and allow much more targeted and efficient implementation. The actual benefits and costs of WSP implementation will vary considerably from utility to utility. This document sets out a summary of the issues that need to be taken into account.

It is the experience of many water suppliers that illegal or unauthorised access to the distribution network can occur for a variety of reasons. This poses a number of water quality risks and can also create wider problems related to loss of revenue. This document briefly summarises the water quality risks associated with unauthorised access and how they can be mitigated.

В настоящее издание Руководства по обеспечению качества питьевой воды включено опубликованное в 2004 году третье издание, а также первое дополнение к третьему изданию, опубликованное в 2006 году, и второе дополнение к третьему изданию, опубликованное в 2008 году. Настоящее издание заменяет собой предыдущие издания Руководства и Международные стандарты.

В этом издании Руководства далее развиваются концепции, подходы и информация, содержащиеся в предыдущих изданиях, и в том числе впервые изложенный в третьем издании комплексный подход к профилактическому управлению риском в целях обеспечения качества питьевой воды.

Данное Руководство адресовано в первую очередь регулирующим органам систем водоснабжения и здравоохранения, директивным органам и их консультантам в целях оказания помощи в разработке национальных стандартов. Руководство и связанные с ним документы также используются многими другими в качестве источника информации по вопросам обеспечения качества воды и охраны здоровья, а также по эффективным подходам к управлению.

Dans le cadre des efforts continus en faveur de la sécurité sanitaire de l’eau de boisson et de la santé, de nombreux pays ont demandé des orientations concernant la façon d’introduire des plans de gestion de la sécurité sanitaire de l’eau (PGSSE) et d’élargir leur mise en oeuvre. Il n’existe ni modèle ni façon unique de procéder en la matière.
Néanmoins, en se fondant sur l’expérience, une succession d’étapes décrivant comment y parvenir a été définie. Cette « feuille de route » relative aux PGSSE est destinée aux gouvernements et aux autorités chargés de concevoir ou de réviser les réglementations, programmes, et politiques relatifs à l’eau de boisson. Elle peut également se révéler utile pour les distributeurs d’eau et les autres organisations intéressées par l’amélioration des pratiques existantes.

This document summarises the drinking-water quality risks associated with corrosion and sediment accumulation within distribution networks and describes ways that the risks can be mitigated.
