Modelling pathogen health risks associated with stormwater reuse

Project Number # 4113

Bayesian belief modelling of pathogen health risks associated with indirect stormwater reuse

Project Leader:  Dean Mensinga

Growing populations and climate change are placing increased pressures on our water supplies. Stormwater harvesting and reuse offers a potential option to augment traditional water resources. Before it can be utilised within a given context, however, its safety must be established. This project has developed a Bayesian Belief Network (BBN) model representing pathogen sources and treatment barriers within a proposed stormwater harvesting scheme. The BBN can utilise a range of data sources and be constantly updated to assist managers to engage effectively with stakeholders and identify the most appropriate combination of risk management strategies available to them.
