Abstract

This paper is based on a research project with the aim of developing a suitable model for future water consumption in Toowoomba, Queensland, Australia. The project’s main aims were to, systematically, investigate the contributory factors in water usage and then build a mathematical model for prediction and performing sensitivity analysis. Water is without any doubt the most important resource used in farming, industrial and domestic applications. Hence, this project is timely and very appropriate in terms of meeting the needs of the community in and around Toowoomba.

The paper demonstrates how the most suitable multiple regression models were built in a progressive manner. For instance, a systematic investigation into the accuracy of models has revealed that by incorporating three dummy variables and using those in conjunction with either the city population or the number of dwellings in the city would produce the most accurate results. These dummy variables represented the presence or absence of tariff, restrictions rebate and dry weather.
