Dense urban areas suffer from challenges of faecal contamination in the urban environment, particularly in informal settlements and low-income areas. Current sanitation approaches may not be sufficient to improve public health, with a need to better understand how and where pathogens are released and how humans may become exposed.
Employing a systems modelling approach and using a low-income urban settlement in Dhaka, Bangladesh as a case study, this project considered pathogen flows in the urban environment and assessed how different potential sanitation solutions would be expected to influence health risks.
This research also provided the first detailed evidence base on faecal pathogens in environmental samples from sanitation systems, drainage systems and local waterways, raising significant cause for concern, and a need for further research on how pathogen levels can be better reduced.
