Working Paper 2 - Ladders for assessing and costing water service delivery

Research publications

The second edition of Working Paper 2 is now available.

This Working Paper deconstructs the concept of service level ladders as a way to differentiate between broad and recognisable types of services.The service level ladder is about service levels and not infrastructure. WASHCost is testing the hypothesis that differentiating between service levels helps to narrow the range of cost estimates for providing water services. The Working Paper explores costs at, at least, three levels including:

• total aggregate services across the whole population;
• within different service levels; and
• between technology types.

This structure aids data analysis in different countries, not just in terms of the technologies being used, but also in terms of the domestic water services being received.
