HYDRAULIC PERFORMANCE EVALUATION OF WATER SUPPLY DISTRIBUTION NETWORK
Hydraulic network analysis of water supply distribution system to address water distribution bottlenecks within an urban water supply system is important. This can be achieved through investigating the status of the existing distribution system of the network. In this project the hydraulic performance of Olonkomi town is assessed using predefined hydraulic formula in spreadsheet. The main objective of this study is to investigate the hydraulic performance of the water distribution system of the town. The analysis was performed using predefined hydraulic formula in spreadsheet for average day demand and peak hour demand. After analysing the water distribution system results for allowable maximum pressure, minimum pressure and velocity was used as base to evaluate the hydraulic performance. From analysis result, it is observed that there are different problems in the system. These are aged pipes, undersized pipes, low pressures and low velocity. This problem has been solved by replacing the aged pipes with new one and using the design criteria of velocity and pressure for undersized pipes, low pressure and low velocity. Finally, 44% of the total distribution pipe lines need modification currently at the base year which are smaller diameter and above its service life of steel pipe and should be replaced with newer one.
