Hydraulic performance evaluation of Yeka Abado supply zone of Addis Ababa's water distribution network
A water distribution network's crucial feature is providing adequate water supply to meet the required demand with satisfactory performance. The objective of this study was to evaluate the hydraulic performance of the Yeka Abado supply zone in Addis Ababa and suggest corrective measures to the problems obtained through the evaluation. A computer model was created in WaterGEMS to simulate the water distribution network. An intermittent scenario was created based on customer meter data to check the ability of the system to meet the current demand in the study area. Two scenarios were developed to evaluate the system's ability to satisfy the current and future demands in a continuous supply. The model analysis result indicated that pressure below the acceptance criteria at some junctions during peak hours, shortly after the supply, had resumed during intermittent operations. The performance remained satisfactory at other time steps. Furthermore, analysis in a continuous supply scenario for predicted future flows in 2044 indicated that the system is unable to meet the increasing demands in the study area, requiring system expansion works at some point. The results for a continuous supply model for 2021 indicated an excellent performance, with almost all the acceptance criteria being met.
