The PhD Thesis covers a review of sanitation technology options for
urban slums including existing technologies, their application
status and the knowledge gaps. A novel method for selection of
sustainable sanitation technologies in urban slums is presented as
an alternative to software applications. This method promotes
holder participation and ensures sustainability of the selected and
implemented sanitation systems. Furthermore, this PhD research
provided an insight into the genomic copy concentrations of
selected waterborne viruses in a typical urban slum and the
magnitude of microbial risks to human health caused by pathogens
(bacteria and waterborne viruses through various exposure pathways.
The results show that urban slum environments are polluted and the
disease burden from each of the exposure routes. In addition, the
grey water production in urban slums is more than 80% of the water
consumption and the grey water pollutant loads pose potential
public health and environmental impacts. The PhD thesis also covers
aspects of optimisation of the filtration medium during grey water
treatment by uPVC filter columns in series and parallel mode. In
addition, the study demonstrated that grey water treatment using a
two-step crushed lava rock filter unit at household level in an
urban slum is feasible. The grey water pollutant loads reduced by
50% to 80% after grey water treatment. The main conclusions on
sanitation in unsewered urban poor areas and recommendations for
future research are included in this PhD thesis.
