About       Water, Sanitation and Hygiene (WASH) sector institutional cost mapping examines the existing and available unit cost information in the sector and the use of life-cycle cost information in planning and decision making processes in rural, peri-urban and small town areas in Sierra Leone.

The objective of the institutional cost mapping of the Water, Sanitation and Hygiene (WASH) sector was to provide an understanding of overall sector governance, institutions, and decision-making processes which make use of WASH costs in Sierra Leone. 

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).
