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.

How to prepare Water Safety Plans for community-managed water supply systems in rural Nepal – Nepali
This package has been developed for WaSH practitioners seeking to develop water (probably more correctly, WaSH) safety plans with rural communities who manage their own water and sanitation systems. Although the overall guide is in English, all of the resources to be used with the community are in Nepali.
How to prepare Water Safety Plans for community managed water supply systems in rural Nepal – ENGLISH
This package contains tools and resources for developing water safety plans (they could be considered "WaSH Safety Plans") in rural communities where the water and sanitation is managed by the community themself.
Whilst it was developed for Nepal, these tools may be applicable for community managed systems around the globe.
Sustainability of Water Safety Plans Developed in Sub-Saharan Africa
The WSP approach was elaborated within two cooperation projects implemented in rural areas of Burkina Faso and Senegal by two Italian NGOs (Non-Governmental Organisations). In order to evaluate its sustainability, a questionnaire based on five different sustainability elements and a cost and time consumption evaluation were carried out and applied in both the case studies. Results demonstrated that the questionnaire can provide a useful and interesting overview regarding the sustainability of the WSP; however, further surveys in the field are recommended for gathering more information. Time and costs related to the WSP elaboration, implementation, and management were demonstrated not to be negligible and above all strongly dependent on water quality and the water supply system complexity.
Climate Ready Water Utilities
Climate change is important to consider in all aspects of utility operations and planning because it can impact both the water resources as well as the infrastructure necessary to provide clean and safe water. The Climate Ready Water Utilities initiative is a practical and easy to use tool developed by EPA to assists the drinking water, waste water and stormwater utilities in understanding and addressing climate change risks and impacts as well as preparing operators systems’ for the impacts of climate change.
Guidelines for using Web-Enabled Water Safety Plan Tool
The Water Research Commission (WRC) project K5/1993//3 “Web enablement of a water safety plan and incorporation of existing similar supply system assessment tool” aimed to establish a methodology to identify and manage the risks of water services infrastructure and the means by which Water Services Institutions (WSIs) are better able to identify and manage these through use of Water Safety Planning. The tool assists in developing a Water Safety Plan. Implementation thereof (e.g. taking required actions, implementing corrective actions, developing and implementing management and communication procedures) of the Water Safety Plan depends on the Water Services Institution (WSI).
