System Assessment

System assessment is the part of the Water Safety Plan that evaluates whether a water supply system is capable of producing drinking water that meets the health-based targets. System assessment can be done at increasing level of detail, requiring more site specific information as the level of detail increases. Four case studies are presented with increasing level of detail, showing the type of information that is required for each of these levels and how each level informs risk management. The first case study shows how a system assessment can be performed without other site specific information than the type of source water and the type of treatment processes. The required data for the system assessment are collected from the large body of literature available. The second case study uses site specific microbial indicator data. The third study uses pathogen data and the fourth case study combines data on pathogens, microbial indicators and process parameters. The case studies show that the level of detail required largely depends on the risk management question.

Background: The quality of water for human consumption is an objective of fundamental importance for the defense of public health. Since the management of networks involves many problems of control and efficiency of distribution, the Water Safety Plan (WSP) was introduced to address these growing problems. Methods: WSP was applied to three companies in which the water resource assumes central importance: five water kiosks, a third-range vegetable processing company, and a residence and care institution. In drafting the plan, the terms and procedures designed and tested for the management of urban distribution systems were applied to safeguard the resource over time. Results: The case studies demonstrated the reliability of the application of the model even to small drinking-water systems, even though it involved a greater effort in analyzing the incoming water, the local intended use, and the possibilities for managing the containment of the dangers to which it is exposed. This approach demonstrates concrete effectiveness in identifying and mitigating the dangers of altering the quality of water. Conclusions: Thanks to the WSP applied to small drinking-water systems, we can move from management that is focused mainly on verifying the conformity of the finished product to the creation of a global risk assessment and management system that covers the entire water supply chain.

This article discusses the benefits of an innovative approach to the problem of water security introduced by WHO in 2004, through the establishment of the Water Safety Plan (WSP). It was recently included in Commission Directive (EU) 2015/1787 – October 6, 2015 – the implementation of which is expected in the EU countries by 27 October 2017. The WSP is the most effective means of consistently ensuring the safety of a drinking water supply. The method is based on the use of a comprehensive risk assessment and risk management approach that involves all steps in water supply from catchment to consumer. The knowledge acquired by some experiences of WSP application, both inItalyand in countries with limited resources, is proving the effectiveness of the model as the best way to manage drinking water systems and protect public health.

Water Safety Plan

The Water Safety Plan (WSP) concept has become a globally recognised and accepted approach to drinking water supply management and operation. Many countries around the world are adopting this proactive, risk-based model for ensuring consistent confidence in drinking water safety, accessibility and affordability. While it is widely accepted that the WSP concept is an appropriate tool for ensuring drinking-water supply efficiency, the process for gathering the required evidence to demonstrate this continues to be rather vague. The problem may lie fundamentally in the way WSPs are developed and implemented. This paper discusses the need for establishing performance targets, identifying key performance indicators and monitoring these to build a body of evidence that would be instrumental in demonstrating whether WSPs are effective or not.

Water Safety Plan

Following international developments and the new WHO Drinking Water Guidelines (WHO 2004) a process-orientated concept for risk, monitoring and incident management has been developed and implemented in this study. The concept will be reviewed with special consideration for resource protection (first barrier of the multi-barrier system) and in turn, for the Water Safety Plan (WSP) which adequately considers—beyond the current framework of legal requirements—possible new hygienic-microbiologically relevant risks (especially emerging pathogens) for the drinking water supply. The development of a WSP within the framework of risk, monitoring and incident management includes the application of Geographical Information Systems (GIS). In the present study, GIS was used for visualization and spatial analysis in decisive steps in the WSP. The detailed process of GIS-supported implementation included the identification of local participants and their tasks and interactions as an essential part of risk management. A detailed ecological investigation of drinking water conditions in the catchment area was conducted in addition to hazard identification, risk assessment and the monitoring of control measures. The main task of our study was to find out in which steps of the WSP the implementation of GIS could be integrated as a useful, and perhaps even an essential tool.

Water Safety Plans

A safe supply of drinking water is a cornerstone of public health and community well-being. Complacency among those responsible for the provision of safe drinking water (e.g., water suppliers, operators, and managers) has led to numerous and otherwise avoidable waterborne outbreaks. Water safety plans present a risk-based, proactive framework for water management, and when properly implemented, virtually eliminates the option for complacency. However, the uptake of water safety plans remain limited worldwide. This paper reports on the experiences of early water safety plan adopters and identifies a number of non-technical operational and human factors that have undermined previous efforts. Specifically, it identifies these factors as a gap in the water safety plan implementation literature and suggests incorporating the broader community in water safety planning through a community readiness approach. Assessing and building community readiness for water safety plans is suggested to be a critical pre-implementation step, and a potential tool for use by water suppliers and by policy makers.
