| dc.description.abstract | Debark is one of the rapidly growing towns in Ethiopia. Intermittent water supply, a lack of drinking water, and water loss issues are common problems in Debark town. The primary goal of this study was to evaluate the hydraulic performance of the Debark To wn water distribution system. Face-to-face interviews, field surveys using questionnaires, and observation were used to gather primary data.The secondary data was gathered from reports and design documentation. In addition, a model utilizing Water GEMS 10.02 software was developed to evaluate the existing water distribution system. The zone of higher and lower pressure connections as well as the pipe's velocity were determined using the model. To examine the distribution system, the simulation runs for peak and low demand conditions were undertaken.According to the analysis, the current total daily domestic water demand ofthe town is 1749.068m3/day, its water supply is covered to a 44 % extent, this outcome suggests that there is an imbalance between supply and demand. The town lost 19.131% of its water when compared to the total amount of water produced. While the real losses account for 60% of the overall losses, the apparent losses account for 40%. The results of the modeling revealed violations of the minimum and maximum pressure and velocity requirements at various nodes and pipelines. In general, the analysis's findings and the questionaryresults indicate that the town's water distribution system's overall hydraulic performance was unsatisfactory, as evidenced by its low rate of water production; low rate of water consumption; high level of non-revenue water; low level of service coverage; and failure to maintain allowable pressure and velocity. Therefore, it is important to rehabilitate and enhance the water distribution system's capacities by drilling new boreholes, constructing pressure zones, and increasing pumping rates. In addition, focusing more on water loss reduction techniques and policies is essential for corrective actions.
