Être ambitieux, s’engager prudemment, puis élargir le champ d’action

by WHO/IWA, 2010

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.

Experiential Learning through Role-Playing: Enhancing Stakeholder Collaboration in Water Safety Plans

by Giuliana Ferrero et al., 23. February, 2018

Improved water safety management, as addressed by the Sustainable Development Goals, can be aided by Water Safety Planning, a risk-assessment and risk-management approach introduced
by the World Health Organization and implemented to date in 93 countries around the globe. Yet, this approach still encounters some challenges in practice, including that of securing collaboration among the broad range of stakeholders involved. This paper presents a role-playing game designed to foster stakeholder collaboration in Water Safety Plans (WSP). In this role-play, participants take on different stakeholders’ roles during a collective (team-based) decision-making process to improve water supply safety in a fictive town. The game is the result of a transdisciplinary initiative aimed at integrating knowledge across technical and governance aspects of WSPs into an active learning experience for water sector actors from diverse backgrounds. It exposes participants to the four phases of Kolb’s experiential learning cycle: concrete experience, reflective observation, conceptualization and active experimentation. This paper discusses potential impacts of the WSP role-play, including skills and knowledge development among participants, which can support cross-sectoral integration and dealing with complexity in decision-making. These are capacity assets strongly needed to address water safety management challenges in a sustainable way.

Factsheet: Engaging vulnerable groups in the implementation of CR WSP

by IWA, 10. March, 2021

Water is a fundamental need in every person’s life and ensuring access to safe water for all without discrimination is a human right, recognized by the United Nations (UN) in 2010. The global commitment to safe water for all is further demonstrated through the Sustainable Development Goal (SDG) 6 targets to achieve universal and equitable access to safe and affordable drinking-water for all. However, many people cannot yet claim their fundamental right to water, and inequalities to safe water access is felt disproportionately by those who are disadvantaged socially, economically, demographically, or geographically.

Read more on how to engage vulnerable groups in CR WSP in this factsheet.

Guidelines for Drinking Water Safety Plans for Buildings in Hong Kong

by Water Supplies Department et al., 21. September, 2017

根據世界衛生組織(WHO)的建議,香港水務署最近編制了建築物水安全計劃的指引和範本,協助業主或物業管理代理制訂水安全計劃,以風險為本和多重障礙的方法,加強建築物的食水安全。建築物水安全計劃的實施,有賴物業管理和水喉業界人士的共同努力,包括辨識和評估內部供水系統的潛在風險,制定控制措施和執行相應的檢查和保養。此外,通過定期審核和檢視,物業管理可以驗證和更新建築物的水安全計劃。香港水務署已於2017年9月推出建築物水安全計劃的指引和分別合適一般建築物和學校使用的範本後,供建築物業主或物業管理代理自願參與。

Based on the recommendations of the World Health Organization (WHO), the Water Supplies Department (WSD) of Hong Kong has recently developed guidelines and templates for Water Safety Plan (WSP) for Buildings. The guidelines and templates aim at assisting building owners or management agents to develop their own WSPs to enhance water safety in buildings by using a risk-based and multiple barrier approach. Implementation of WSP for buildings requires concerted efforts of building management and plumbing practitioners, including identifying and assessing potential risks of the inside service, deriving control measures and carrying out the corresponding checking and maintenance. In addition, the WSP will be verified and updated by the building management through periodic auditing and review. The guidelines and templates for general buildings and schools have been launched in September 2017 for voluntary adoption by building owners or management agents.

How current risk assessment and risk management methods for drinking water in The Netherlands cover the WHO water safety plan approach

by H.H.J.L. van den Berg et al., 03. July, 2019

In the Netherlands, safe and sufficient drinking water is provided to the general population by ten drinking water companies. To guarantee safe drinking water the World Health Organization (WHO) developed a Water Safety Plan (WSP), a Risk Assessment and a Risk Management (RA/RM) framework. The objective of the study was to
identify legally required RA approaches, to document application of RA/RM activities at Dutch drinking water companies and to determine to what extent these RA/RM activities as a whole cover all the elements of the WHO WSP approach. This study could be of interest to both managers of large water utilities and decision makers.

The assessment was performed by means of a policy review and interviews with two to four staff members involved in RA/RM from all ten Dutch drinking water companies combined with a joint workshop. The drinking water companies are well aware of the potential hazards and risks that can influence the drinking water quality. To guarantee the supply of safe and sufficient drinking water, the Dutch drinking water sector uses six different legally required RA/RM approaches. This study shows that by using the six legally required RA/RM approaches, all WSP steps are covered. WSP entails a generic risk assessment for identifying all hazards and hazardous events from source to tap, whereas the six legally required RA/RM each focus on specific risks at an advanced level.
Each risk assessment provides information on specific hazards and hazardous events covering a part of the water supply chain. These legal requirements are complemented with additional RA/RM activities at sector and water company level such as codes of practices and standard operating procedures. The outcomes of all RA/RM approaches combined provide information from source to tap. When using multiple RA/RM approaches, it is crucial to share and combine information derived from the different activities.

Implementation and evaluation of the water safety plan approach for buildings

by Isabelle Schmidt et al., 30. October, 2019

The World Health Organization (WHO) promotes water safety plans (WSPs) – a risk-based management approach – for premise plumbing systems in buildings to prevent deterioration of drinking-water quality. Experience with the implementation of WSPs in buildings were gathered within a pilot project in Germany. The project included an evaluation of the feasibility and advantages of WSPs by all stakeholders who share responsibility in drinking-water safety. While the feasibility of the concept was demonstrated for all buildings, benefits reported by building operators varied. The more technical standards were complied with before implementing WSP, the less pronounced were the resulting improvements. In most cases, WSPs yielded an increased system knowledge and awareness for drinking-water quality issues. WSPs also led to improved operation of the premise plumbing system and provided benefits for surveillance authorities. A survey among the European Network of Drinking-Water Regulators on the existing legal framework regarding drinking-water safety in buildings exhibited that countries are aware of the need to manage risks in buildings' installations, but experience with WSP is rare. Based on the successful implementation and the positive effects of WSPs on drinking-water quality, we recommend the establishment of legal frameworks that require WSPs for priority buildings whilst accounting for differing conditions in buildings and countries.

Including aspects of climate change into water safety planning: Literature review of global experience and case studies from Ethiopian urban supplies

by Bettina Rickert et al., 13. May, 2019

In recent years, the water safety plan approach has been extended towards climate-resilient water safety planning. This happened in response to increasing insight into impacts of climate on drinking-water and required adaptation to anticipated climate change. Literature was reviewed for published guidance and case examples, documenting how to consider climate in water safety planning to support future uptake. Climate-resilient water safety plans were piloted within a project in the water supplies of Addis Ababa and Adama, Ethiopia.

Case examples have been published in four of six WHO regions with a focus on urban supplies. Integration of climate aspects focused mostly on the steps of establishing the team, system description, hazard analysis and risk assessment, improvement planning and development of management procedures. While the traditional framework focuses on drinking-water quality, considering climate change augments aspects of water quantity. Therefore, other factors affecting water quantity such as population development and demand of other sectors need to be considered as well. Local climate information and tools should be employed as a significant success factor for future uptake. Such information should be incorporated as it becomes available, and may – depending on the setting – be incrementally integrated into existing water safety plans or used to develop new ones.

Legionella spp. Risk Assessment in Recreational and Garden Areas of Hotels

by Antonios Papadakis et al., 26. March, 2018

Several Travel-associated Legionnaires’ disease (TALD) cases occur annually in Europe. Except from the most obvious sites (cooling towers and hot water systems), infections can also be associated with recreational, water feature, and garden areas of hotels. This argument is of great interest to better comprehend the colonization and to calculate the risk to human health of these sites. From July 2000–November 2017, the public health authorities of the Island of Crete (Greece) inspected 119 hotels associated with TALD, as reported through the European Legionnaires’ Disease Surveillance Network. Five hundred and eighteen samples were collected from decorative fountain ponds, showers near pools and spas, swimming pools, spa pools, garden sprinklers, drip irrigation systems (reclaimed water) and soil. Of those, 67 (12.93%), originating from 43 (35.83%) hotels, tested positive for Legionella (Legionella pneumophila serogroups 1, 2, 3, 6, 7, 8, 13, 14, 15 and non-pneumophila species (L. anisa, L. erythra, L. taurinensis, L. birminghamensis, L. rubrilucens). A Relative Risk (R.R.) > 1 (p < 0.0001) was calculated for chlorine concentrations of less than 0.2 mg/L (R.R.: 54.78), star classification (<4) (R.R.: 4.75) and absence of Water Safety Plan implementation (R.R.: 3.96). High risk (≥104 CFU/L) was estimated for pool showers (16.42%), garden sprinklers (7.46%) and pool water (5.97%).

Lessons learned from practical CR WSP implementation and auditing in Africa and Asia.

by Rory Moses McKeown,

Water, sanitation and hygiene (WASH) have a significant impact on health and, of particular concern as described in the recent Intergovernmental Panel on Climate Change Special Report on Extreme Events, are the risks of more frequent and intense extreme weather events such as floods, cyclones and droughts, alongside increasing temperatures. Such extremes pose particular challenges to the capacity of WASH programmes to protect health, and there is accumulating evidence that climate change is worsening these risks.

A national programme of water safety plan (WSP) auditing was undertaken in 2018/19 with a particular focus on climate resilience, to learn lessons from the pilot WSPs and adapt the programme in advance of future scale-up.

Linee guida per la valutazione e gestione del rischio nella filiera delle acque destinate al consumo umano secondo il modello dei Water Safety Plans .

by Luca Lucentini et al., 2014

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.

Unsafe drinking water is a recognized health threat in Ethiopia, and climate change, rapid population growth, urbanization and agricultural practices put intense pressure on availability and quality of water. Climate change-related health problems due to floods and waterborne diseases are increasing. With increasing insight into impacts of climate change and urbanization on water availability and quality and of required adaptations, a shift towards climate-resilient water safety planning was introduced into an Ethiopian strategy and guidance document to guarantee safe drinking water. Climate-resilient water safety planning was implemented in the urban water supplies of Addis Ababa and Adama, providing drinking water to 5 million and 500,000 people, respectively. Based on the risks identified with climate-resilient water safety planning, water quality monitoring can be optimized by prioritizing parameters and events which pose a higher risk for contaminating the drinking water. Water quality monitoring was improved at both drinking water utilities and at the Public Health Institute to provide relevant data used as input for climate-resilient water safety planning. By continuously linking water quality monitoring and climate-resilient water safety planning, utilization of information was optimized, and both approaches benefit from linking these activities.

Measuring the Impacts of Water Safety Plans in the Asia-Pacific Region

by Emily Kumpel et al., 10. June, 2018

This study investigated the effectiveness of Water Safety Plans (WSP) implemented in 99 water supply systems across 12 countries in the Asia-Pacific region. An impact assessment methodology including 36 indicators was developed based on a conceptual framework proposed by the Center for Disease Control (CDC) and before/after data were collected between November 2014 and June 2016. WSPs were associated with infrastructure improvements at the vast majority (82) of participating sites and to increased financial support at 37 sites. In addition, significant changes were observed in operations and management practices, number of water safety-related meetings, unaccounted-for water, water quality testing activities, and monitoring of consumer satisfaction. However, the study also revealed challenges in the implementation of WSPs, including financial constraints and insufficient capacity. Finally, this study provided an opportunity to test the impact assessment methodology itself, and a series of recommendations are made to improve the approach (indicators, study design, data collection methods) for evaluating WSPs.
