In the 3 rd edition of the Guidelines for Drinking-water Quality, the World Health Organisation (WHO, 2004) emphasis the preparation of risk-based Water Safety Plans (WSPs) to manage risks to drinking water consumers. WHO, among others, emphasise that the entire supply system, from source to tap, should be considered when managing risks. The WSP framework(More)
It is recognized that the usual output of a fault tree analysis in some studies is not sufficiently informative. For added value in a widely used instrument for doing risk analyses, a Markovian approach is suggested. It is shown how to extend the calculations of the standard fault tree gates, so that information is available not only on the failure(More)

Within Work Area 4 (WA4), Risk Assessment and Risk Management, in the TECHNEAU project, six case studies on risk assessment were carried out for six different drinking water systems during 2007-2008. The main purposes of the case studies were to assess the specific drinking water systems, evaluate methods and tools developed in WA4 and provide good examples(More)

Within Work Area 4 (WA4) Risk Assessment and Risk Management, in the TECHNEAU project, six risk assessment case studies were carried out at different drinking water systems during 2007-2008. This report presents a risk assessment of the drinking water system in Göteborg, Sweden. The assessment was carried out using an integrated and probabilistic fault tree(More)
The development of strategies for adapting risk management to suit future water supply systems requires prediction of emerging risks. Identification of existing risks and risk that are likely to be important in the future is a key issue to the TECHNEAU project (TECHNEAU, 2005). This information is essential to the development of adaptive strategies in work(More)
