Practice and tools - Module 3

In various countries, sector stakeholders already apply approaches and tools to improve the sustainability of their WASH interventions. WASHCost has developed tools for collecting and analysing cost information and measuring service levels. By reviewing cases and sharing experiences, participants will analyse and think of ways to apply a service delivery approach for WASH in their own country. Participants will also do practical exercises on application of service level indicators and use for the collection and analysis of cost information. Module 3 provides the practical cases and tools for improving sustainability within your organisation’s remit.

Life-cycle Cost Approach - Module 3

Module 3 of the Costing Sustainable Services Training package enables users to analyse life-cycle costs and service levels for water and sanitation. It discusses:

What are my life-cycle costs? Determine how life-cycle costs impact on overall expenditure in the next 20 years. Which life-cycle cost components are most significant, such as capital expenditure or operational expenditure? What is the impact of rehabilitation and renewal of WASH infrastructure? What is the overall cost of the loan that was taken out?
Forecasting expenditure: who pays for what? Over the 20 years following an intervention who will pay for which life-cycle cost components? What is the potential impact of inflation and population growth?
Comparing sustainability risks with expenditure. Modelling shortfall in expenditure based on breakdown rates and renewal costs and some typical operational costs. Comparing whether the expenditure expected is going to be enough to ensure the sustainability of the service delivery model.
Comparing WASH service levels received by users across projects, districts, regions or countries. Identifying gaps between ‘designed for’ and ‘received’ services.Comparing how services differ across population groups.
