Sustainable total sanitation - Nigeria: Final research report

This report presents the final results of the impact evaluation of two of WaterAid Nigeria's main interventions within the programme "Sustainable Total Sanitation Nigeria - implementation, learning, research, and influence on practice and policy" (STS Nigeria project for short). The impact evaluation was conducted in the states of Ekiti and Enugu. The two interventions under evaluation are Community-Led Total Sanitation (CLTS) and Sanitation Marketing (SanMark). Both interventions aim at increasing the level of improved toilet ownership and its sustained usage, with the final goal of eliminating community-wide open defecation (OD).
