This working paper sets out a common framework to analyze and compare sanitation cost data across countries with different service delivery standards (i.e. Burkina Faso, Ghana, Mozambique, India). It represents a fundamental shift away from the focus on capital investment costs, to the costs of sustainable sanitation services. In this second edition of the paper, indicators found to be more useful than others have been added. Appendices A & B contain tentative outline ladders for solid waste and for greywater.
- All elements of a sanitation service require a different hardware system so service levels should be assigned separately for excreta and urine management, greywater (ie. domestic wastewater), and for solid waste.
- The sanitation service level ladder has two levels of acceptable services: 'basic' service and 'improved' service.
- Hygiene promotion is an important advocacy issue because it will only result in sustainable behavior change if it is an ongoing, integrated service.
- It is beyond the realistic scope of WASHCost research to collect cost and service level data for the full range of hygiene services in any focus country.
- With respect to field testing, household data collection should be analyzed against the service level indicators to ensure that sampling includes examples of all different service levels.
