In a town having an established water system the per capita con-sumption is kno^vn and the quantity of water required for extendingthe system can be estimated with a fair degree of accuracy. Ina small town or community in which a public supply is designed toreplace private weUs an estimate of the amount of water requiredshould be based on a comparative study of the consumption in townsof similar characteristics. Plans for cities or for smaller communi-ties involve consideration of future needs based on the probablerate of increase in population and the circumstances affecting it,and also on the estimated rate and amount of development of indus-trial enterprises. In a State such as Connecticut, where the sig-nificance of past conditions and present trends of population and in-dustries are fairly well understood, an average town of less than 10,000inhabitants may plan for a 20-year service on the basis of the pr
