This study was carried out to evaluate a simple, inexpensive, continious flow swab sampler (CSS) technique. The retaining capacity of the filtration pad (400x30 cm, surgical cotton gauze) is limited at a maximum count of 10 organisms/swab. This technique is efficient as a quantitative, or at least rough quantita tive, when it is used for clean water sampling. Samonella enteriti dis, Salm. typhimurium and coloured Staphylococci organisms in addition to other bioindicators were isolated from Nile water at the intake and along the treatment plant. Acid-fast, staphylo cocci and yeasts commonly resist chlorination effects than the coliform group.
