Faecal pathogen flow modelling in urban environments: a proposed approach to inform sanitation planning

Project Duration April 2017 - August 2017 Category: Sanitation models, user behaviour, user experience Delivered by: Institute for Sustainable Futures, University of Technology Sydney
Themes: Faecal sludge management Health impact Hygiene Planning Research Sanitation Urban Sanitation Research Initiative


To build towards better understanding of pro-poor sanitation investment practice, and to (potentially) lay the foundation for possible future research around sanitation investment planning in low-income contexts in Bangladesh, Ghana and Kenya.


The proposed model uses a “source-pathway-receptor” approach: it considers release of pathogens into the environment, transport in the environment, and eventual human exposure.

Next steps

The model can potentially provide a framework for comparing the relative impacts of different sanitation options on health; the next step should be to test the approach in a real city.

A follow-on project is now underway in Dhaka, Bangladesh.
