ASSESSING THE MAINTENANCE PERFORMANCE OF THE KWANYAKU WATER TREATMENT PLANT
The study assessed the Maintenance Performance of the Kwanyaku Water Treatment Plant. Availability and reliability of eleven facilities from the old and Jubilee treatment plants were compared. Twenty respondents view on the Maintenance Schedule at the Kwanyaku Headworks was also obtained. The t-test was the main statistical tool used with an alpha level of 0.05. There were significant differences in the availability of the equipment at the two treatment plants where the old recorded 93.33% better than the jubilee 77.50%. Also, there were significant differences in the average reliability of 48.20 days and 11.00 days for the facilities at the old and the jubilee plants respectively which fell below the GWCL benchmark and plant manufactures’ standard. The assessment further revealed significant differences in the maintainability of the two plants which were within the GWCL benchmark of 1 – 5 hours. Finally, the study revealed that the main causes of frequent plants and equipment failure at the treatment plant were power outages and instrumentation issues.
