The study was carried out on water samples collected from different sites in Swakin City and Arbat area in Sudan. Five samples were collected during two seasons (winter and summer) to determine the quality of the drinking water by looking into physicochemical and microbial aspect. Results showed that some samples exceeded the Sudanese and international standards in turbidity and some samples showed the presence of coliform, E. coli and faecal streptococcus bacteria. It is recommended to carry out microbial examination frequently for water in the distribution system.
