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