Abstract The most important reason for storage water in special tanks in the buildings and houses is an insufficient amount of water. These tanks enhance the causative agent of water contamination through several aspects like its shape, size, color, position, cleaning….etc., therefore, the current study was aimed to investigate the effect of tanks material on the microbial quality of water in Shualat Al-Sadrain region in Baghdad city through four summer months Jun, July, August, and Septembe 2017. 120 water samples were collected from 40 tanks of drinking water, three samples were taken from each tank at the same time. These tanks divided into two groups 20 tanks were made from galvanized iron, and the rest 20 tanks were made from plastic. The temperatures of water were recorded at the time of collection. These entire water samples were undertaken to microbial test in the laboratory of a hospital of Baghdad in the medical city in Baghdad. The results show significant differences in bacterial growth between two types of tanks. Enterobacter contamination involves E. Coli, Fecal E. Coli, Klebsiella and Proteus among plastic tanks. In the conclusion: A lot of factors affect water contamination in tanks, whereas the most important one is Iraq climate, which leads to conclude that the galvanized iron tank is suitable and has fewer disadvantages than a plastic one in Iraq and hot areas.
