13. Developing a Multilinear Regression Water Consumption Model: A Case Study of Addis Ababa City, Ethiopia

Determining water consumption using an appropriate water consumption method is fundamental in ensuring future domestic water security. Many water consumption projection studies, especially in developing countries, are performed using the traditional approach of forecasting using population and per capita consumption. In this study, we developed a new water consumption projection model for Addis Ababa by considering socioeconomic and climate change factors. The model was developed using multilinear regression statistical analysis to select the most significant factors affecting domestic water consumption. The results show that socioeconomic development, specifically rapid population growth, is the most significant factor driving water consumption in Addis Ababa.
