Management of solid waste in on-site sanitation systems (Uganda)

The aim of the study was to investigate the management of solid waste in on-site sanitation systems (OSS) in Kawempe and Makindye divisions in Kampala City. Primary data collection was done by interviews, focus group discussions and direct sampling of solid waste from pit latrines and septic tanks. It was shown that Kawempe division had more solid waste in pit latrines and septic tanks (603 kg and 10.38 kg, respectively) than Makindye division (490 kg and 8 kg, respectively). Textile materials were the dominant solid waste materials in both divisions and were composed largely of menstrual hygiene products and baby diapers. Participants mentioned that solid waste ended up in pit latrines and septic tanks due to lack of knowledge on the effects that solid waste can cause in the OSS, lack of suitable storage containers for solid wastes, convenience (nearer, easy, design of squat holes for pit latrines), and cultural norms. It was recommended that in order to improve the management of solid waste in both divisions, awareness raising of the effects of poor solid waste management, provision of better alternative infrastructure, provision of better solid waste storage containers in homes, enforcement of the laws and regulations, collaboration with the relevant stakeholders, development of incentives and promotion of recycling of polythene bags and plastic bottles should be undertaken.
