Adopters and non-adopters of low-cost household latrines: A study of corbelled pit latrines in 15 districts of Malawi

The Sustainable Development Goals will challenge low- and middle-income settings to look at new approaches for rural sanitation. In 2013, Mzuzu University, in partnership with United Nations Children\u27s Fund (UNICEF) Malawi, started a low-cost latrine program in rural areas using the corbelled latrine design supported by locally owned sustainable businesses. The objective of this work was to trace customers (early household adopters) and non-customers through field observations and interviews in 15 districts of Malawi. The research team spent 193 personnel work days in data collection and found 21 households as adopters in 7 districts. Most respondents had a preference with regard to the design of the sanitation facility they would like to use. Although sharing of sanitation facilities was common, the corbelled latrine is promoted as a single household pit latrine design. Unfortunately, 8% (23/304) of non-adopters responded they practiced open defecation. Households were satisfied with the corbelled latrine design, and no latrine was found to have collapsed during field visits. To promote the corbelled latrine in Malawi, the following are recommended: (1) education of frontline government extension workers towards non-subsidized household latrines; (2) identification of rural low-income households as the best target for potential adopters; and (3) linkage of low-cost sanitation technologies to community mobilization campaigns led by the government, such as Community Led Total Sanitation
