This note is based on a working paper of the WASHCost project and sets out current thinking on defining and stratifying water service delivery. To do this, a ‘ladder’ has been developed, with each up step the ladder representing a clearly defined qualitative and quantitative improvement in service provided to  users. The WASHCost project looks at the life cycle costs of providing sustainable WASH services in Burkina Faso, Ghana, India (Andhra Pradesh) and Mozambique. The service delivery ladder has been developed, and will be tested, by WASHCost to enable like-with-like comparison of water service delivery across different countries and contexts. The objective is to be able to answer the question: what does it cost to sustainably provide a given level of water service over the full life-cycle of the different elements of the service delivery system(s). WASHCost will also use the ladder to investigate and compare designed-for service with actual service received. In WASHCost a service level is understood to contain clearly defined (and normative) range of acceptable values for a set of key indicators of service provision: quantity, quality, reliability, accessibility, and status.
