Factors influencing selection of drinking water technologies for urban informal settlements in Kampala

Access to drinking water in urban informal settlements of developing countries still remains a challenge for the poor and depends on technology selected. This paper determines the score on criteria used for technology selection by two major stakeholders in the water service delivery chain, the users and the utility. The criteria are: affordability to connect, affordability of consumption, method of payment, ease of operation, ease of spare parts acquisition, access distance, access time, generating sufficient water continuously, service coverage, the possibility of cost recovery and security of installation (SOI). The study was carried out in Bwaise II and Kisenyi III, two informal settlements in Kampala, the capital of Uganda. Through a household survey and semistructured interviews of key informants, data were collected for the score on these criteria of four piped water distribution technologies: public water points (PWPs) with conventional meters, PWPs with prepaid meters, house connections and yard taps. Using multicriteria methods and preference elicitation by pair wise ranking, the most preferred factor for technology selection from the users' point of view is affordability to connect, while from the utility's point of view, it is SOI. These preferences were confirmed by data from focus group discussions and in-depth interviews.
