chapter  3
Supply: the economist’s perspective
Pages 23

Chapter 2 has given a brief account of the nature of the hydrological cycle and a fuller description of what may be fairly called the hydrosocial cycle. The purpose of Chapter 3 is to consider the supply of fresh-and wastewater services as an economic phenomenon, principally with reference to the costs of production, although here excluding environmental costs, a subject to be returned to in Chapters 7 and 8.
