V. Bergion, V., Lindhe, A., Sokolova, E. and Rosén, L. Accounting for unexpected risk events in drinking water systems
Waterborne pathogens can cause gastrointestinal disease, and the costs to society in terms of human suffering, healthcare costs, loss of production, etc. could be substantial, especially in the case of a larger waterborne outbreak. To provide safe drinking water, the entire supply system, from catchment to consumer, must be considered. If the risk level is too high, risk mitigation measures are required. These mitigation measures are often expensive, and the decision on how to choose the most suitable measure must be made using a holistic approach.
In this thesis a decision model is presented. The decision model supports drinking water producers in their evaluation of microbial risk mitigation measures, and acts as an aid when choosing the alternative that is most beneficial to society. The novelty of the decision model lies in the combination of several different methods to describe the transport routes of pathogens in drinking water systems. The model is also novel in integration of multiple scientific fields to enable a thorough evaluation of microbial risk mitigation measures considering societal benefit and profitability.
