Estimating domestic water usage in a tropical environment: exploring socio-demographic perspectives

Abstract

Abstract Water demand at any given time, particularly at the household level, depends on various factors, including climatic variables, social, economic, and demographic factors. Achieving consistent availability and accessibility, coupled with effective resource management, is crucial, particularly in tropical regions. Understanding all these variables is essential to achieving these goals. This research aimed to assess the impact of ten socio-demographic variables on predicting household water demand in Iwo. Two hundred and twenty-five households were randomly selected, with 196 completing and returning the survey. Both descriptive and multivariate analyses, specifically Factor and Regression Analysis, were employed to analyse the data. Factor analysis (FA) identified four variables: (i) housing characteristics; (ii) marital status; (iii) income level; and (iv) gender distribution, in that sequence. These four variables collectively accounted for 68.608% of the variance in household water demand in Iwo. This outcome underscores the importance of giving due consideration to these variables in water supply planning by relevant authorities. The study contributes to a better understanding and quantification of the significant variables influencing household water demand. However, it is advisable that future investigations into household water use incorporate additional variables beyond socio-demographic factors to comprehensively comprehend factors influencing water demand at the household level.
