Optimierung der Abwasserentsorgung aus Siedlungsgebieten im subsaharischen Afrika - Ein Beitrag zur Stadtentwicklungsplanung (in German and English)
Optimisation of wastewater treatement from urban areas in sub-Saharan Africa - a contribution to urban planning

Urban wastewater management is a complex issue, particularly in sub-Saharan Africa where urbanisation rates are among the highest in the world and innovative solutions are required.
The findings refer to legal, political, organisational, social, technical and economical issues. Time-consuming and costly allocation of land contributes to the high proportion of informal settlements for which the utilities do not have a mandate to serve. Political neglect in many cases outweigh technical problems, fair financing means a must. Without participation, information for users and a certain freedom of choice between costs and convenience, sanitation upgrading projects are doomed to fail. Conditions for successful privatisation are discussed and regulations for urban agriculture with wastewater are examined. The essay concludes with an outlook on how far the findings can be generalised for other cities in the regions.
