Content - Summary

The objective of this research, which was limited to a desk top study, was to find out the most suitable sanitation system for urban and peri-urban areas (considering urban agriculture) by using a multi-criteria analysis for comparing options. The case study was carried out for urban and peri-urban areas in Accra and in Lima with the main focus being on the Accra Metropolitan Assembly (AMA).

It seems that Accra and Lima are not on the track to meet the MDG target for sanitation coverage. The common constraints found for achievement of MDG targets are lack of finance (for people and government), lack of technology, lack of political will, and insufficient land. Ecosan approaches could play a major role in achieving MDG targets 1, 2, 5, 8, 10, and 11 at lower cost than conventional sanitation systems.

Main recommendations from this thesis include carrying out conceptual design with more specific detail for every part of the sanitation components (Part A to E), cost estimation with accurate quantities and costs especially for the toilet itself and urine storage, and designing and cost estimation for greywater management systems.
