| dc.description.abstract | Water network performance is defined as the ability to deliver a required quantity of water under sufficient pressure and an acceptable level of quality. Systems that have big transmission line may have problem on changes of pressure in the distribution system. Because pressure rate changes have been too much between water treatment plant and dead ends in distribution system. This study is to analyze the effects pressure changes on the water quality in water distribution systems for case study of Akaki phase 3B water supply system was assessed. Efforts were also made to identify the relationship between the residual chlorine and pressure in the distribution of the water supply network systems using Water Cad software /tool to model water distribution system. Accordingly, simulation results show that, for maximum and minimum pressures were used as base to evaluate the hydraulic performance; and simulation results for minimum residual chlorine were used as base to assess water quality transformation in distribution system. Pressure has a direct relationship with residual chlorine. Pressure change has been causing to increase chlorine consumption more. The result of pressure changes among others can decrease in chlorine content and hydraulic factors, because the systems may be extensive and thus possess complex networks and hangs in quantity cause pressure of flow. Hence hydraulic changes (pressure) could affect of water quality in the water distribution system. | en_US |
