Understanding the role of informal pit emptiers in sanitation in Nairobi through case studies in Mukuru and Kibera settlements

Abstract

Achieving universal sanitation in informal settlements will depend on improved onsite sanitation, as sewer systems are unlikely to be viable solutions due to technical and political constraints. In Nairobi, Kenya, 60% of the population live among its 150 informal settlements, occupying only 5% of its total residential land. This research assessed the role of informal pit emptiers in providing sanitation in Mukuru and Kibera, two of the largest informal settlements in Nairobi, and the barriers to achieving improved services. Through qualitative data collection, the research found that pit emptiers are institutionally and physically outside of the current paradigm of sanitation service delivery. There is no infrastructure available to remove waste from informal settlements, except for a transfer station that is being piloted by Sanergy, and instead waste ends up disposed in the community. The pit emptiers also face violence and intimidation from competitors or locals claiming ownership of territory. Providing improved sanitation in such areas will depend on the provision of new infrastructure, but this can only succeed with a detailed understanding of the competing and vested interests that can enable or undermine a project.
