Modeling of Urban Water Supply and Water Loss in Distribution System of Adwa Town Using Hydraulic Simulation, Ethiopia

Tsegay brhane


The main objective of this Research is to modeling of urban water supply and water loss in the distribution system of Adwa town under its major water supply source of Midmar Dam. This Research is conducted in Adwa town to model the water supply distribution system, the existing water distribution system of the town is both pump and gravity system. the water from the treatment plant of Adiabun to the storage reservoir by the pump. Then, the stored water is distributed by DCI, PVC, and GI pipe materials to the town by gravity. The research also depends on secondary data from the CSA Census report, and the meter reading reports at the District offices of Adwa town. In this study the data is entered, coded and analyzed using Bentley water GEMS V8i (SELECT series5.The analysis result shows the domestic and non-domestic water supply coverage of the town is 56.13%. The hydraulic Simulation in the existing water system to satisfy the Adwa town has been approved for hydraulic parameters such as head, pressure, and flow rate. The collected data on the number of water losses, causes of water losses, to reduce losses, and the challenges ahead have been collected and analyzed taking international the association best practice of water loss strategies.
