Although there is no market for a water service to be evaluated, there are other markets in which these benefits are embedded (for instance, real property transactions near an water aesthetic place will somewhat incorporate these benefits, although bundled with other attributes of the property).
This method is based on the assumption that the price of a marketed good is a function of its different attributes, and an implicit price exist for each of these.
Chapters 1-3 have introduced IWRM and the need for economic and financial instruments. For them to be effective, contributing to sustainability, and improved access to basic services, they need to be applied.
Their application will be examined in the next two chapters.
