Crowd-sourced spatio-topological sanitation network modelling in informal systems

Jul 17, 2015

Abstract

Improvements in sanitation provision, and in particular options for collection and treatment of sewage, are critical requirements to reduce health and environmental risks to populations in rapidly-urbanising informal settlements. This paper presents a novel technique to evaluate the costs of different sewage treatment-transportation options based on the spatial and topological properties of different networks. This is made possible using crowd-sourced, open spatial data-sets which allow us to simulate different sanitation network scenarios within a geospatial software environment, and ascertain the long term operational costs of different network configurations. It is envisaged that such a tool could be used by engineers as part of the sanitation planning process to evaluate sanitation network implementation options, as such we include a case-study example based on the Kibera settlement in Kenya.
