In this study a real case is used in order to evaluate the effect of the factors controlling the residential water demand in one of the suburb of the state of Kuwait. The important of this study comes from the fact that our case study has at the same time two kinds of residential areas in which one the them contains complete and modern water and sewage networks, while the other is lacking this surface.
Therefore an evaluation of the effect of the availability of water and sewage networks on residential water demand is made by making a comparison studies between two different residential areas. These two residential areas have the same controlling factors for water demands, such as economical conditions, climatical conditions, standard of living, and social life.
The method presented is based on a sensitivity analysis of the effect of the availability of water and sewage networks on the per capita daily water demand compared to water demand at the other part of our residential area with no water and sewage networks.
The analysis of data from both residential areas showed a greater water demands for all houses that located at the part of no availability of water and sewage networks which is in contrast with assumption that the demand for water will increase with water and sewage networks.
