Assessing operational performance benefits of a Water Safety Plan implemented in Southwestern France
Aims: The World Health Organization (WHO) has recommended Water Safety Plans (WSPs)
since 2004 as a means to reduce drinking water contamination and risks to human health.
These risk management programs have shown promise across several potential areas of
evaluation, such as economic benefits and regulatory compliance. Since WSPs are largely
carried out by people who interact with water treatment equipment and processes, operational
performance indicators may be key to understanding the mechanisms behind desirable WSP
impacts such as water quality and public health improvement.
Method: This study reports performance measures collected at a WSP implementation
location in southwestern France over several years.
Results: Quantitative assessment of performance measures supported qualitative reports from
utility managers. Results indicate significantly reduced duration of low-chlorine events at one
production facility and a significant decrease in customer complaints related to water quality,
manifesting reported improvements in operational performance and the customer service
Conclusion: The findings demonstrate some success stories and potential areas of future
performance tracking. Cyclical iteration of the WSP can help to achieve continuous quality
improvement. Successfully applied evaluation criteria such as the number of water quality
complaints or alarm resolution time might be useful across other locations.
An Economic Assessment of Drinking Water Safety PlanningKoror-Airai, Palau
This document describes a preliminary economic assessment of the Koror-Airai, Palau drinking water safety plan. The information generated is to be used to inform stakeholders in Palau of the rewards from supporting the DWSP approach, demonstrating the potential benefits of investing in the Plan.
A role-playing game for practising stakeholder collaboration in Water Safety Plans
One of the challenges in the implementation of Water Safety Plans (WSPs) is stakeholder engagement. For this reason, IHE Delft Institute for Water Education has developed a role-playing game for practising stakeholder collaboration in WSP. The game can be used in WSP training or during educational activities for water safety and WSP at graduate and post-graduate level. Its goal is for participants to experience the importance of stakeholder engagement in WSPs, and particularly in the decision-making process when investing in the rehabilitation and maintenance of a drinking water supply system from catchment to consumers. Participants will experience how this process can be influenced by information exchange between stakeholders and how this will eventually lead to greater awareness when assembling the WSP team.
A practical guide to auditing Water Safety Plans
This document 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 criteria, audit timing and frequency and audit reporting. The guidance document includes examples, tips, tools and case studies, and it serves as a practical resource for policy makers, government bodies responsible for drinking-water regulation or surveillance and water suppliers implementing WSPs.
A Journey Towards Safe Drinking Water for All
This water safety plan country report for Sri Lanka shares the key learnings from the country's WSP journey and achievements. The lessons learned can support the broader WSP global community for successful and practical WSP implementation.
A guide to equitable water safety planning: Ensuring no one is left behind
The lack of access to safe drinking-water is felt disproportionately by those who are disadvantaged socially, economically, demographically or geographically, and explicit consideration of these groups is required to understand and address disparities.
This document describes how, with relatively modest efforts, the water safety plan (WSP) approach can bring tangible improvements in water quality and availability for all users. By providing step-by-step guidance for all WSP stakeholders, as well as good practice examples from a broad range of countries and contexts, this document serves as a practical tool to help achieve safe water for all.
The electronic version of the PowerPoint slides presented in Tool F of the document, available under “Downloads” above, is intended to facilitate the integration of equity considerations into standard WSP training events.
A guide to conducting household surveys for Water Safety Plans
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.
A Conceptual Framework to Evaluate the Impacts of Water Safety Plans
This paper outlines a conceptual framework for conducting this type of overall evaluation of the impacts of a WSP. Drawing examples from existing WSPs in various regions, the framework also illustrates the types of intermediate outcomes that can be expected during WSP implementation. This conceptual framework, which requires some familiarity with WSPs, is designed to be one of a set of tools to guide the implementation and evaluation of Water Safety Plans, along with the WHO guidelines (WHO, 2006), the Water Safety Plan Manual (Bartram et al, 2009) and other tools and resources developed for national or regional use1
Water Safety Planning (WSP), an approach which aims at ensuring safe drinking-water thorough a comprehensive risk system assessment and management process since its adoption by the International Water Association (IWA) and World Health Organization (WHO) seeks to support achieving the Sustainable Development Goal (SDG) target 6.1 to provide safe drinking-water for all.
Since its adoption, national governments have included them in national legislation to promote their implementation because of its immense benefits.
In scaling up effective up of WSP implementation across these different countries, this worldwide accepted approach needs to be supported by tools, resources, regulations and policies, guidelines to create the enabling environment and support stakeholder participation at the national level.
IWA with support from OPEC Fund for International Development (OFID), under the Climate Resilient Water Safety Planning Project has produced this document with a summary of existing national policy and guidelines to support WSP implementation.
