Evaluation and classification of water use rate policy using the Points Credit Index

Abstract

In order to be able to have clean water piped to our homes, an enormous investment both in money and expertise is required. The typical household water consumption, industrial, commercial, government sectors and agricultural authorities are known to be of several types of country's water consumption slices (stresses) which controls the water industry of any country. A mathematical model called STRESS has been developed, which demonstrates the relationship between various stresses with respect to consumption rate and costs which impact water use economy. The method of a Points Credit Index (PCI) was developed that is based on the following factors: credit, volume of consumption, and tariff systems, where the earlier accounts for both the environmental and the socio-economic norms represented by the PCI system. The model evaluates the various stresses to determine the correct tariff with respect to the PCI concept. This method will enable decision-makers to draw a logical conclusion on how much these stresses can change the water-use rate of a certain country. The significance of this paper is that it is the first attempt to evaluate water consumption by the PCI system, which controls the high consumption rate initiated by various stresses and predicts a suitable consumption tariff for each of the different stresses.
