The effect of intake works corrosion on water quality and remedial measures were investigated to generate data and information on the corrosion of intake work members and various means through which this problem can be fixed while giving the intake work members a longer lifespan. Primary and secondary data were collected for studies. Analysis of water sample collected at the intake point was carried out to estimate some water quality parameters such as total dissolved solids (TDS), pH,  temperature, dissolved oxygen (DO), total hardness and calcium hardness, concentrations of iron, zinc, aluminum and fluoride. A corrosion rate of iron bars immersed in water for 7 days, 14 days and 49th days were calculated. A simple mathematical linear relationship connecting the corrosion rate and total dissolved solids was established. The results obtained indicated the existent of a simple linear regression equation that is suitable for the prediction of some water quality parameters. It was also deduced from the results that there is a development of an electrochemical cell consisting of the cathode with the intake water serving as an electrolyte and a sacrificial anode (used to close the circuit). The setup enhances the intake works members to gain weight in the process becoming cathodically protected and the water finally at the intake point becoming purer and clearer.
