The study was carried out on water samples collected from different sites in Singa city, Sudan. Thirty samples of drinking water were collected randomly during summer, autumn, and winter for two succesive years 2019 and 2020.The objective of the study was to determine the quality of drinking water by looking into physicochemical and microbial aspect. The physicochemical and microbial analysis were performed according to the American Public Health Association, American Water Works Association and Water Pollution Control Federation. The physicchemical analysis were performed for temperature, PH, electrical conductivity(E.C.),turbidity, and total dissolved solids (T.D.S.).The microbial analysis were performed to detect the presence of microorganisms such as total coli form, Escherichia coli and faecal streptococcus. Results showed that the temperature of the samples were within the limit in summer, but exceeded the Sudanese Standarad Limits in autumn and winter. The PH, (E.C.) and (T.D.S.)were within the Sudanese Standards .Results showed the presence of coliform, Escherichia coli and faecal streptococcus in some samples, and this indicated that some water samples were unfit for human consumtion It is recommended to carry out bacteriological examination frequently for water in the distibution system.
