ABSTRACT
As the first statement indicates, the main problem is that, in general, we take water supply for granted. Only when there is too much or too little does it seem really important. And whilst most of us accept water supply without much thought there is, in fact, a whole industry whose sole purpose is to make sure that water is supplied in the right quantity, at the right quality and at the right place at the right time. There are thousands of people employed in the water supply industry and tens of thousands more involved in supplying its equipment, from dams to stop cocks, from raingauges to computers. So here hydrology and man interact in the provision of water for irrigation, industry and domestic use, for amenity, transport and so on.
