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.

The Water Safety Plan (WSP) approach is an iterative method focused on analyzing the risks of water contamination in a drinking water supply system, from catchment to consumer, in order to protect human health. This approach is aimed at identifying and drastically reducing water contamination in the entire drinking water system, through the identification and mitigation or, if possible, elimination of all factors that may cause a chemical, physical, microbiological and radiological risk for water. This study developed a proposal of WSP for the drinking water supply system (DWSS) of Mortara, Italy, in order to understand which are the preliminary evaluation aspects to be considered in the elaboration of a WSP. The DWSS of Mortara (a town of 15,500 inhabitants, located in northern Italy) consists of three drinking water treatment plants (DWTPs), considering the following main contaminants: arsenic, iron, manganese and ammonia. Potential hazardous events and associated hazards were identified in each part of the water supply system. The risk assessment was carried out following the semi‑quantitative approach. The WSP proposal for Mortara was very useful not only as a risk mitigation approach, but also as a cost-effective tool for water suppliers. Furthermore, this approach will reduce public health risk, ensure a better compliance of water quality parameters with regulatory requirements, increase confidence of consumers and municipal authorities, and improve resource management due to intervention planning. Further, some new control measures are proposed by the WSP team within this work.

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.

The third edition of the WHO Guidelines for Drinking-water Quality establishes a ‘Framework for Safe Drinking-water’ that promotes a risk assessment and risk management approach called Water Safety Plan (WSP). In Germany, the discussion on the WSP approach started with significant scepticism by various stakeholders questioning its added value in light of the high quality and service level of water supply. In response, the Federal Ministry of Health, the Federal Environment Agency and the DVGW Association for Gas and Water jointly took the leadership for initiating a sectoral dialogue process involving water suppliers and local public health offices, including a series of WSP pilot projects to evaluate WSP feasibility, benefits and expected challenges for scaling-up. As the regulatory system in Germany makes explicit reference to ‘generally acknowledged codes of good practice’ the paper also examines how far the suite of established DVGW technical and managerial standards already supports WSP implementation. The evaluation process confirmed an added value of the WSP approach under Germany's national conditions, clearly providing an impetus for safeguarding a high quality and service level of drinking-water supply. Various activities to support scale-up implementation of a WSP-type approach have been initiated, including the preparation of step-by-step guidance in German (i.e. DVGW Guidelines W 1001), information campaigns to broadly raise awareness amongst all stakeholders in water supply, and capacity building initiatives.
