Pathogen flows: applying public health principles to urban sanitation

Thursday 31 August | 16.00-17.30 | Room: NL Music Hall

The world is urbanizing fast, and traditional wastewater solutions are increasingly inadequate in densely populated areas. This threatens water resources as well as public health, disrupting the water cycle. Historically wastewater engineers have focused on reducing biological contamination, rather than removing pathogens. In recent years, our awareness about fecal waste flows and environmental pollutants has grown, but pathogen flows, exposure and public health risks have received less attention.

Put simply, we do not yet know which waste flows and exposures are the most significant threats to public health; without this understanding, we cannot maximize the impact of sanitation interventions.

While we don’t know enough to predict flows and subsequent risks very well, we do know enough to ask useful and challenging questions about “business as usual” which can help planners and managers reconsider choices between sanitation options. This event will span solid and liquid fecal wastes, in sewered and unsewered settings.

The latest global research developments will be shared. Through participatory processes, we will be challenged to critically examine assumptions and knowledge gaps about pathogen removal, liquid discharges and sanitation investment choices, and learn about the potential for pathogen flow thinking to improve sanitation understanding and action.
