As developing countries are faced with maintaining waterresources and building adequate delivery systems, it isimportant to analyze historical data to determine actuallevels of use. In many developing countries, however, records withthe necessary level of detail have not been maintained. Therefore,it is especially important to account for a variety of factors thatmay influence usage rates.This paper explores how water use trends are specific to localconditions and how making the assumption that per-capita ratesin the United States, for example, will also be achieved in developingnations can lead to overdeveloped systems. Evidence isgiven regarding how many times gross estimates are made offuture water demand based on assumed increase factors andways in which these assumptions can be incorrect.This article identifies actual changes in water use over timeand provides actual water use data for a range of consumersectors to assist in planning demand. The article also examinesthe impact of water cost on domestic use. Includes 20 references, tables, figures.
