Water quality monitoring and evaluation provides important information to estimate water system status. Clean water prolongs someone’s life through equitable health facility. Residents suffer of unclean water service provided by the utility Service provider due to lack of sophisticated methods of treatment. This research seeks to monitor and improve the water treatment process at various stages. In this regard, multivariate statistical process control (MSPC) techniques specifically, the multivariate exponentially weighted moving average (MEWMA), the Hotelling’s T2 and the ellipse control charts have been applied to water statistical data. Monitoring was centred only on two basic water parameters namely; total suspended solids (TSS) and biochemical oxygen demand (BOD). These two parameters play a pivotal role in the composition of quality drinking water and they normally exhibit a high correlation. Results show that the process of treating water for human consumption is not statistically in control hence requires improvement.
