This work therefore seeks to assess the water quality characteristics and benchmarking it with the World Health Organisation’s (WHO) standard. It also attempts to generate a mathematical model for optimising capacity in relation to mix and number of technical personnel. Data on water quality characteristics was gathered and subjected to statistical analysis. Failure records on each production equipment were obtained from the maintenance unit of the respective plants to calculate failure rate, F and reliability, . Regression analysis was performed on the data to generate the correlation and coefficient tables hence the model. The result revealed that none of the waterworks perform all the 14 mandatory tests (due to paucity of test equipment). Capacity utilisation, CU of the water production plant is weakly dependent on number of engineers, e; number of technologists, T, number of technicians, t; number of craftsmen, c while it is strongly a factor of the plant’s reliability Rp. The equation CU = 35.664 - 0.969e + 1.027T + 0.026t - 0.216c + 53.441Rp was found to be a valid model for optimising capacity utilisation of the selected plantenWater quality characteristicscapacity utilisationArticle
