This book is written in the belief that water is becoming one of the largest, and certainly the most universal, of problems facing mankind as the earth moves into the twenty-first century. The tasks of supplying enough water of the required quality to growing populations and the safe disposal of wastewater are straining many authorities to the limit. Although the problem varies in type and intensity, it is challenging governments of countries at all stages of development, in most parts of the world. It will be argued in this chapter that in many cases the failure to treat water as a scarce commodity lies at the heart of the problem. Chapter 2 discusses various approaches to problem solving, and makes the case for the greater use of ‘demand management’, where by better use is made of existing water supplies instead of automatically investing in new supply capacity to satisfy imagined future requirements.
