Quantitative Analysis and Statistical Modelling of Water Consumption of Five Star Hotels in Delhi, India

Abstract

Five star hotels are intensive users of fresh water resources. This study investigates various independent variables affecting water consumption. Water consumption modelling and its validation have been undertaken. Twenty seven hotels operating in Delhi were selected for collection of relevant data through a questionnaire and field survey. Statistical analysis has been carried out using the Statistical Package for Social Sciences (SPSS) software and R-software for principal component analysis (PCA) to identify influential variables in respect of the water consumption pattern. The three water consumption equations, in terms of total water consumption, consumptive uses and non-consumptive uses, have been developed using multiple regression analysis. These equations have been able to explain the 85%, 82% and 78% respectively of the original variability. These developed equations for determining the water consumption are useful to reduce the freshwater usage and to promote reuse of treated wastewater for non-potable purposes.
