Provision of sanitation solutions in theworld's urban slums is extremely challenging due to lack ofmoney, space, access and sense of ownership. This paper presents a technology selectionmethod thatwas used for the selection of appropriate sanitation solutions for urban slums. The method used in this paper takes into account sustainability criteria, including social acceptance, technological and physical applicability, economical and institutional aspects, and the need to protect and promote human health and the environment. The study was carried out inBwaise III; a slumarea in Kampala (Uganda). Thiswas through administering of questionnaires and focus group discussions to obtain baseline data, developing a database to compare different sanitation options using technology selection criteria and then performing a multi-criteria analysis of the technology options. Itwas found that 15% of the population uses a public pit latrine; 75% uses a shared toilet; and 10% has private, nonshared sanitation facilities. Using the selection method, technologies such as Urine Diversion Dry Toilet (UDDT) and biogas latrines were identified to be potentially feasible sanitation solutions for Bwaise III. Sanitation challenges for further research are also presented.
