Determination of Failure Mode and Effect Analysis on Water treatment Plant in Greater Lokoja Water Work

Abstract

Water is essential to Nigerian agriculture, household necessities, and industrial purposes. Several issues, including population expansion, maintenance, inadequate water infrastructure, pollution, and climate variability, make it increasingly difficult to obtain safe water for consumption. The problem of water supply in Lokoja and its environment has been a challenge. This problem is caused by failure of the plant components that lead to the downtime of the plant hence, low production. It can be addressed by using Failure Mode and Effect Analysis (FMEA). This research is aimed at determining the failure mode and effect analysis on water treatment plants in greater Lokoja water works. Data were collected using Fuzzy Failure Modes and Effect Analysis (FMEA) technique and analyzed using phyton software. The result shows that FMEA is technique is effective in addressing the water challenges in Lokoja cities. The G2 (pipe) has the highest percentage of 8.9%; B1 (valve), B2(valve) and E1(membranes) have the lowest percentage of 5.0%. C1(filtration system) has the highest percentage of 9.3% and A2, B1(valve), D2(chemical dosing system), E2(membranes) and G2(pipe) have the lowest percentage of 5.3%. A1(pump) and C1(filtration system) have high percentage contribution of 8.0%. B2(valve), E2(membranes) and F1(water storage system) have the lowest percentage contribution of 5.3%. Preventive and corrective action plans were equally developed to address the frequent breakdown of water supply components and machines.
