| dc.description.abstract | This thesis focused on evaluating the hydraulic performance of the existing water distribution system in Durbete town, located in the North Gojam zone of the Amhara region in Ethiopia. The study utilized statistical analysis and the Water GEMS software. The statistical analysis was applied to analyze the current water supply coverage, total water loss of the entire town, and the Water GEMS model was used to model all the distribution system networks and evaluate the overall hydraulic performance of the system. The analysis revealed that the per capita water consumption in the town is 31.41 liters per person per day, indicating a gap between demand and supply. The average level of household connection is 73%. The total water loss in the system is 33.7% (178,590 m³/year) of the system input volume, with 10.89% being unavoidable real loss and 22.76% being apparent loss plus avoidable real loss. Additionally, 35.13% (186,168 m³/year) of the total water supplied is non-revenue water. The hydraulic performance modeling was developed to examine the water distribution system's performance. However, there were discrepancies between the simulated and measured values that affected the system. In addition to pressure, the system was affected by low velocities due to low demand and the use of high-diameter pipes. These low velocities can potentially affect water quality due to water stagnation in the pipes. To address all my study issues, I recommends involving infrastructure development, management practices, technology adoption, and community engagement to improve the water supply coverage of the system. Regular inspections, advanced leak detection technology, and rapid response to leaks are needed to reduce the total water loss. Additionally, rehabilitation and improvement of the water distribution system capacities, establishing pressure zones, increasing pumping rates, and drilling additional boreholes are recommended to enhance the overall performance of the water distribution system.
