Overview

Historically, water demand forecasts have been determined by estimating current per-capita water consumption multiplied by expected future population. However, this method does not account for changes in the economy, technological advances, or conservation habits, nor does it take into account the overall trend of declining water use. Water demand forecast methods must accommodate these changes, as well as account for the impact of conservation programs, demographic changes, and climate change. This issue brief gives an overview of water demand forecasting, and suggests techniques to increase the accuracy of forecasts.
