With a view towards improving the robustness of financial and economic analysis, this paper discusses current approaches towards the assessment of costs and benefits associated with
sanitation improvements. Using results from a study that compares urine diversion dehydration toilets with conventional sanitation technologies in sub-Saharan Africa, the authors highlight challenges related to financial and economic modeling of sanitation systems. Excreta reuse is identified as a specific area where there is a need for further development. Specific attention is placed upon the quantification of the economic benefits of excreta reuse and the authors describe the approach for monetising these benefits. The authors offer specific recommendations for improving the robustness of this analysis, and propose a framework for categorizing financial and economic parameters for project design, sanitation programming, and policy-making. The authors argue that the consistent application of the proposed framework, combined with the standardisation of methodologies and the systematic collation of financial and economic data is required for future studies to assess the financial and economic costs and benefits of different types of sanitation systems.
