The research was aimed at eliminating Vibrio cholerae from raw sewage collected from home spills of Chegutu, Zimbabwe. An experimental approach was used in which homogenized raw sewage, inoculated with Chlorella vulgaris culture was distributed equally into three tanks and left to stand for three weeks. Samples were extracted from the three tanks and tested for the presence of Vibrio cholerae and physico-chemical parameters once in seven days. Results showed a continuous decrease in the quantities of Vibrio cholerae as well as physico-chemical parameters. Vibrio cholerae was totally eliminated from the sewage within 21 days. Chlorella vulgaris can be used as a bioremediation agent to eliminate the Vibrio cholerae from sewage. The research recommends that the prototype designed from this research could be used at a large scale in the elimination of Vibrio cholerae in Municipal raw sewage.
