Abstract

This study focuses on a comparison of sanitation technologies suitable for urban settlements. It compares ecosan with conventional sanitation systems in terms of financial and economic costs and benefits based. An analytical framework and a computer model were developed to assess and compare different technologies in terms of financial and economic Net Present Value (NPV). The economic benefits derived from improved sanitation include health and environmental benefits, as well as those which are associated to excreta reuse. The study is based on case studies, which all promoted Urine Diverting Dry Toilets (UDDTs) in Kabale, Uganda, eThekwini, South Africa and Ouagadougou, Burkina Faso. Based on the case study analysis, none of the currently implemented systems are seen to provide an obvious model for scaling up without considerable external support. Much research is still required to assess the costs of marketing ecosan compared with conventional sanitation, and to assess the costs of different management arrangements. A communal excreta management system such as that in Burkina Faso may overcome some of these constraints, and is more appropriate in denser urban environments.
