About    This briefing note examines the costs of hygiene interventions and the effect of the hygiene interventions on behavioural practices based on a survey conducted by WASHCost team in Kenema and Port Loko districts.

The Community Led Total Sanitation (CLTS) approach has been implemented in Sierra Leone since 2008 and is now in the ‘scale up’ phase (Youssef, Nallo, & Pinkney, 2011). CLTS entails the facilitation of the community’s analysis of their sanitation profile, their practices of defecation and the consequences, leading to collective action to end open defecation (Kar & Chambers, 2008). 

Cost effectiveness is determined by assessing the total cost incurred over the intervention against the change in reported hygiene service levels. Cost effectiveness analysis allows programme managers, governments, donors and researchers to compare programme costs with the outcomes of the intervention. 

This Briefing Note is part of a series of notes that present findings and lessons learned from a WASH Cost study, undertaken by KNUST/IRC in Sierra Leone between 2013-2014. There are five briefing notes that, in order, focus on institutional and sector mapping; costs of providing rural and small towns water services; costs of providing rural sanitation services; costs and effectiveness of hygiene interventions; and water, sanitation and hygiene services in Sierra Leone. Methodologies used in this study included primarily the WASHCost Water, Sanitation and Hygiene service level ladders and the Life Cycle Costs Approach (LCCA).
