EAWAG – Assessing the Costs of on-Site Sanitation Facilities

Assessing the Costs of on-Site Sanitation Facilities, 2016.

Authors: Lukas Ulrich, Prit Salian, Caroline Saul, Stefan Jüstrich & Christoph Lüthi. EAWAG.

This report compiles the findings of a multicountry study comparing costs of on-site sanitation infrastructure in Asia and sub-Saharan Africa. It attempts to provide answers to the question why hardware costs for on-site sanitation are so much higher in Sub-Saharan Africa than in Asia and examines the main factors that lead to these high costs. The report specifically looks at the capital costs of household-level, on-site sanitation technologies which are prevalent in most cities and rural areas of Africa and Asia.

This report provides a detailed analysis of the reasons for cost differences between the countries studied. It also gives specific and field-tested recommendations on how the problem of high costs can be addressed (including prefabrication to increase productivity and decrease construction time, the development and use of material alternatives, as well as financing mechanisms like microcredits and subsidies).
