Intervention mapping as a framework for planning the implementation of urine diversion toilets and Ecosan education in a community school in Kavre, Nepal

Use of human excreta as fertilizer is not a new concept. However, with the use of the modern water-flush toilet, human excreta becomes mixed with water and causes environmental pollution. To reemphasize the nutritional value of human urine in the field, a urine diversion toilet was constructed in a community school situated in Kavre, Nepal. The purpose of establishing the urine diversion toilet is to improve hygiene outcomes through promoting proper sanitation and transforming the school community’s regular practice and attitudes towards urine as a resource. To ensure effective implementation of the urine diversion toilets, intervention mapping was used as a guiding framework. The aim of this paper is to document how the urine diversion toilet was planned and implemented in the school and how the urine diversion toilet was connected with the curriculum to address concerns regarding water, sanitation, and hygiene with a focus on sustainability through intervention mapping. This study highlights the benefits of intervention mapping as a systematic and step-by-step process for the planning and implementation of the urine diversion toilet. This study also highlights the benefits of connecting urine diversion toilets with school gardening, and engaging with local government and other stakeholders about the value of the approach.
