Abstract

In this qualitative paper, a method for technical and operational hazard identification of a water treatment plant is described. Here, fault tree analysis is applied to a physicochemical ultrafiltration (UF) membrane train, with the objectives of developing a systematic approach for organizing and improving our understanding of the hazards at the treatment plant operational level that affect the risk of infection from the pathogen Cryptosporidium parvum. The approach was successful in identifying many technical and operational hazards. The fault tree shows that water treatment plant operation is a complex task where many factors must be taken into account. Regarding the removal of C. parvum oocysts, most initiating events relate to the filtration step in the UF system. In the future, quantification of the probability of fault events may help to prioritize interventions at the operational level.
