Considering the importance on vital activities, the water to be used should be clean and not contain disease-causing bacteria. One of the pathogenic bacteria found in water is the bacterium Escherichia coli (E. coli) belonging to the family Enterobacteriaceae. In the commonly used method for the detection of E. coli bacteria, the bacteria distilled from the water sample are planted on endo agar medium and the change in the color of the medium as a result of the metabolic activities of the bacteria is examined by the naked eye. This color change can be recognizable with the human eye in approximately 22 ± 2 hours. In this study, a hardware and a new analysis method which is based on image processing techniques to enable the detection of E. coli bacteria in a shorter time and in a practical way is proposed. The proposed technique is tested with different sowing methods. Results have shown that the detection of bacteria can be done within 8-10 hours with the proposed method.
