Abstract: Water is the most abundant chemical in the human body and plays a central role in the regulation of nutrient transport, toxic waste removal, thermal regulation and digestion, organ functioning and metabolic activities. Bacteria play important roles in the global ecosystems both on land and in the water by their ceaseless labor in cycling of nutrient. Bacteria have both beneficial and harmful effects. Some of the human pathogens easily transfer through by drinking water. The aim of this study is to analyze the microbiological quality of the available drinking water collected directly from various sources, supply outlets, as well as drinking water stored in various containers or storage pots in order to check the drinking water quality and evaluate the awareness of people for maintaining cleanness and hygiene conditions for storage of drinking water. Study area was under the stress of biological contamination which may lead to the water borne diseases. Bacteria like Streptococcus, Staphylococcus, Bacillus, Pseudomonas, E. coli, Enterobacter, Salmonella and Shigella were identified by conventional methods using standard Bergy’s manual. Analysis was performed using culture and biochemical methods. Number of colonies and bacteria identified were subject to statistical work such as Pearson’s correlation, Dendrogram and standard statistical methods by using SPSS software and Past program. Statistical work showed the high level of positive correlation between water samples of few places of Tumakuru city. Diversity indices of bacteria in different samples were tabulated. Results of bacteriological analysis recoded high density of bacteria and statistical work suggest that drinking water of different water samples of offices have correlation, with 0.005 level of significance.
