Development and implementation of water safety plans for small scale supplies in Bangladesh: benefits and lessons learned
This paper presents a case study from Bangladesh describing how WSPs can be developed and implemented for small systems. Model WSPs were developed through consultation with key water sector practitioners in the country. Simplified tools were developed to translate the formal WSPs into a format that was meaningful and accessible for communities to use.

Être ambitieux, s’engager prudemment, puis élargir le champ d’action
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.
Plans de gestion de la sécurité sanitaire de l’eau
En 2004, les Directives de l'OMS pour la qualité de l'eau de boisson recommandaient que les fournisseurs d'eau potable développent et mettent en œuvre des plans de gestion de la sécurité sanitaire de l'eau (PGSSE) afin d'évaluer et de gérer systématiquement les risques.
Ce manuel répond à cette recommandation en décrivant de façon claire et en termes pratiques, comment développer et mettre en œuvre des plan de gestion de la sécurité sanitaire de l'eau. Onze modules de formation fournissent des conseils par étape. Chaque module présente une étape clé dans le processus de développement et de mise en application des plans de gestion de la sécurité sanitaire de l'eau.
Руководство по разработке и реализации плана обеспечения безопасности воды
В 2004 г. в опубликованном ВОЗ "Руководстве по обеспечению качества питьевой воды" поставщикам было рекомендовано разработать и осуществить планы обеспечения безопасности воды, чтобы можно было систематически оценивать риски и управлять ими. С того времени правительства и регулирующие органы, поставщики воды и практические работники все шире принимают на вооружение этот подход, однако ими была высказана просьба о дополнительных методических руководствах.
Данное руководство по разработке и реализации плана обеспечения безопасности воды является ответом на эту просьбу. В нем понятным языком описывается, как практически нужно разрабатывать и реализовывать такой план. В 11 учебных модулях даются пошаговые рекомендации, причем каждый модуль представляет собой один ключевой шаг в процессе разработки и реализации плана обеспечения безопасности воды.

Linee guida per la valutazione e gestione del rischio nella filiera delle acque destinate al consumo umano secondo il modello dei Water Safety Plans .
One decade ago, the World Health Organization recommended that water suppliers developed and implemented Water Safety Plans (WSP) as the most
effective mean to assure the quality of the water supply and the protection of the health of consumers. This model, as transposed in this guideline, consists of the overall risk assessment and risk management from catchment to tap, to protect the water to be destined to human consumption and the system, as well
as to control any process potentially affecting water quality, with the aim of assuring on a continuous way the absence of physical, biological and chemical hazards in drinking water. Risk based approach will also facilitate the flexibility of hazards management of emerging contaminants which are not systematically monitored, and /or vulnerabilities of water supply systems to direct and indirect impacts due to climate change. The guidance is addressed to water suppliers and health authorities as well as to all the stakeholders interested in different way to the drinking water quality. Criteria, methods and procedures are here provided in clear and practical terms to develop and implement WSP in drinking water supplies in Italy, independently by their dimension and by the volumes of supplied water.
