This research deals with three sources for supplying pure drinking water and within the limitations. The first source is drinking water disinfected with chlorine, the second is domestic and imported water sterilized with ozone, and the third source is water for household systems. In this research, the models’ physiochemical specifications were evaluated and compared with the modern Iraqi standard number 417. The first source results showed deviations in the values of turbidity, hardness, chlorine, and bromine. The deviations in the values were treated through an improved coagulation technique using ferric chloride. As for the second source results, they were within the specifications except for the deviation in the value of the sulfate ion for one of the models, and that deficiencies in the treatment processes caused the presence of the sulfate ion in a high percentage. Despite the different types of the third source systems, it gave good results, except for an increase in the percentage of chlorine and bromine, which needs periodic treatment, as the dose of chlorine during sterilization and removal of the bromide ion from raw water are joints of great importance and have environmental and health implications.
