The efficient management of water distribution networks is crucial for ensuring reliable water supply in urban areas. This study focuses on the analysis of the existing water distribution network for the Endagebrial subsystem in Mekelle city, Ethiopia. The primary objective is to evaluate the current performance of the network and identify areas for improvement to meet the growing water demand. Using EPANET 2.0, widely used hydraulic simulation software, the study models the water distribution network to assess its hydraulic performance. Key parameters such as pressure, flow rate, and velocity are analyzed under various demand scenarios. The network’s ability to maintain adequate pressure and flow during peak demand periods is a critical aspect of the analysis. The results indicate that certain sections of the network experience low pressure, particularly during peak hours, which can lead to insufficient water supply to end-users. Additionally, the study identifies areas with high head loss, suggesting the need for pipe replacement or resizing to enhance the network’s efficiency. The analysis also highlights the impact of aging infrastructure on the network’s performance, emphasizing the importance of regular maintenance and upgrades. Recommendations for improving the water distribution network include the installation of pressure-regulating valves, upgrading undersized pipes, and implementing a more robust maintenance schedule. These measures are expected to enhance the overall reliability and efficiency of the water supply system, ensuring that it can meet the future demands of Mekelle city’s growing population. This study provides valuable insights into the current state of the Endagebrial subsystem’s water distribution network and offers practical solutions for its improvement. The findings can serve as a reference for urban planners and water utility managers in Mekelle city and other similar urban settings, contributing to the sustainable management of water resources.
