Abstract

The performance of Asa and Agba dam waterworks in Kwara State, Nigeria was carried out using flow rate (m3/hr), power consumption (kW) and efficiency of the pumps (%). Daily flow rate of low and high lift pumps were obtained from log book of the Asa dam pump operators from 2011 to 2015 while the monthly electrical power consumption was retrieved from the archive of the Power Holdings Company of Nigeria (PHCN) in Ilorin, Nigeria. The data were analyzed using statistical parameters in the Microsoft Excel to determine measures of central tendency such as monthly minimum, maximum, mean and standard deviation. Analysis of Variance (ANOVA) was used to test for statistically significant in the interaction between the flow rate, power consumption and the efficiency of the pumps. Results revealed that maximum efficiency of the pump varies between 35.5 % in 2011 to 20.4% in 2015. Comparison between pump efficiencies and design specification of 75-90 %, implies that the pump is performing below its design specification. The ANOVA results indicate that there is statistically significant interaction between the flow rate, power input and the efficiency of the pumps. It can be concluded that there is need to upgrade and replace the damage pump parts for its optimum performance.
