The purpose of this working paper is to set out sanitation service levels to be applied as an analytical tool for WASH-Cost research on the disaggregated unit costs of water, sanitation and hygiene services. It should be read together with Working Paper 2: "Ladders for assessing and costing water service delivery", which introduces the concept of service levels, service level indicators and the use of ladders as a metaphor and a means to differentiate between broad levels of service. Both are working documents of the WASHCost team, aimed at providing a framework for data analysis to be used and tested by WASH-Cost.
