It is self – evident that a large population will use more water than a small one and that the water use must be, in some measure, related to population. While this certainly true, and while water consumption estimates have been historically on population projections, such techniques are not always satisfactory. As is noted below, water consumptions is also influenced by factors such as climate, economic level, population density, degree of industrialization, cost, pressure, and the quality of the supply. A number of multivariate projection techniques have been developed which relate water use to one or more of these factors in addition to population. When such methods can be shown to be applicable to a particular community they should be used in preference to the procedures presented in this course.
An analysis of the future demand of a particular community should always begin by considering present use. TO the extent possible, consumption should be broken down by classes of users ( domestic, commercial, industrial, public), area of the city, economic level of the users, season of the year, etc. The rather common procedure of dividing total use by to total population to derive a per capita consumption should be applied only with great care, since (1) the entire population may not be served by the municipal system (2) there may be large industrial users which will not change with population, and (3) the characteristics as well as the size of the population may be changing.
