Background: Drinking water is disinfected in different ways. The most common and cheapest one is chlorination. The most important issue in chlorination is place and rate of chlorin injection which should be selected in such a way that residual chlorine in all parts of water distribution network is standard and the related expenditure is minimal. Performing a program for two distribution networks of urban water, this paper aimed to analyze and compare the rate of chlorine remained in the pipe lines and the amount of chlorine used in different parts of the network.Methods: In order to model the networks, the Water Gems software V3/0 was used, and the two networks were modeled and designed in the form of gravity and direct pumping.Findings: Solving the two practical models of water supply networks by the software, the efficiency of these networks was evaluated to determine the optimum injection rate of chlorine. Findings indicated that the residual chlorine in 62% of the tap water of direct pumping network was close to standard limit and that in 100% of gravity network was less than the standard limit. In addition, the amount of used chlorine in the direct pumping network was 6/5% less than that in the gravity one.Conclusion: This study revealed that the optimization of chlorine injection into the networks with direct pumping is possible, applicable and needs less chlorinecompared to the gravity distribution networks.
