  "abstract": "<p>The quality of water has been a key issue in the water industry for most of world. The decline of<br>\ntreated water can be due to physical, chemical and Biological changes that occur in the water<br>\nthroughout distribution. The disinfectant and Age of water can affect the quality of the water<br>\nbeing distributed. In this study the purpose was to model and Analysis the decay of chlorine and<br>\nwater age by using water cad software and supportive other software. In addition the performing<br>\nthe network considering chlorine concentration, water tracing analysis is done to know the<br>\namount of water exists in system. The simulations were performed with water cad, Google earth<br>\nand global mapper software by using extended period. On other hand laboratory result and water<br>\ncad result is compared to justify exist water quality problem in Bishoftu, chaleleka water<br>\ndistribution system. It was found that the chlorine residual in system was highly affected by<br>\nduration time and distance they have from reservoir where initial chlorine is added into the<br>\nsystem i.e. reservoir and junctions. The performance of chlorine was high due to high initial<br>\nchlorine concentrations, at the around first week of month after addition due to high initial<br>\nchlorine concentration, but after the addition around the end of month the residual chlorine<br>\nconstipation is low. The water age is affected by elevation difference and Demands. To maintain<br>\nthe chlorine concentrations required by WHO (Chlorine residual must be greater than 0.2 mg/l<br>\nand lesser than 0.5 mg/l) chlorination stations were necessary to add initial chlorine into system<br>\nby ratio.</p>",
