Statistical Analysis of Domestic Water Demand and Supply for Kaduna North, Kaduna State

Abstract

Water is life when it’s safe. Water demand means the quantity produced by treatment plants in order to meet all water needs in the community. While water supply is the process of accumulation, transmission, treatment, and distribution. In this study, first-hand information was derived through the process of distributing questionnaires and verbal interviews. The secondary data was obtained from related books, journals, published and unpublished texts, documents magazines, conference articles, government ministries, and agencies. The ministry concerned is of Water Resources. The generated data was analyzed using descriptive and inferential statistics. Interactive linear regression of the data was also employed on R software. The correlation coefficient, R2 of water demand and supply in the area is 1 (i.e.100%). This means there is a strong positive linear correlation between water demand and water supply in Kaduna North. The p-value was obtained as 2.2 x 10-16 which shows that the regression model is statistically significant and negates the null hypothesis. Also, it can be derived from the study Kabala has the largest population with the highest water demand and supply while Ungwan Rimi has the smallest population with the lowest water demand and supply. It is discovered in the study that water demand is more than the water supply in Kaduna North. So, more effort should be put to a water supply to meet the people's demand.
