Disinfection with chlorine is very popular in water and wastewater treatment because of its low cost, ability to form a residual, and its effectiveness at low concentrations. Chlorinated drinking water's chief benefit is the protection of public health through the control of waterborne diseases. It plays a paramount role in controlling pathogens in water that cause human illness, as evidenced by the virtual absence of waterborne diseases such as typhoid and cholera in developed countries. But, there are many factors that can affect the chlorine in the water such as distance. From the Chick’s Law, the concentration of the chlorine residual in water will decrease when the distance increased. By collecting samples and data’s from water treatment plant (Alzarqe Kufa) and its networks by determining the sampling points and the distance from water treatment plant, compare the data’s or levels of chlorine from the network with the levels of chlorine at plant, and check if the residual chlorine in the water supply are following the standard by Iraqi Water Association. From the results, we can improve the quality of the water supply to user to protect the public health through the control of waterborne diseases.
