ABSTRACT

The study was on microbial load of greywater from bathroom. The physico-chemical properties: pH, temperature, conductivity, biochemical oxygen demand, chemical oxygen demand, total dissolved solids, total suspended solids and dissolved oxygen values were high. The total heterotrophic plate count ranged from 4.8 x 1 (10 cfu/ml to 8.7 x 19 cfu/ml, total coliform plate count ranged from 3.8 x 1 cfu/ml to 7.1 x 1 cfu/ml, total Salmonell-aShigelia plate count ranged from 3.0 x 1 9 cfu/ml to 4.6 x 1 9 cfu/ml and total fungal plate count ranged from 3.4 x iø cfu/ml to 5.8 x i09cfu/ml. the bacteria isolated and their percentage occurrence were E. coil (16.67%), Salmonella spp (16.67%)., Shigella spp(8.33%)., Pseudomonas spp (12.5%)., Bacillus spp. (12.5%), Kiebsielia spp. (12.7%), Serratia spp (4.16%). and the fungi isolated and its percentage occurrence were Aspergillus niger (36.36%), Rhodotorulla spp (27.28%). and Aspergillus flavus (36.36%). The ANOVA, P<co.05 showed that there was significant difference in the bacteria and fungi mean count among the different grey water samples. The result revealed that the greywater from bathroom were highly contaminated with pathogenic microorganisms, therefore adequate hygiene practice should be carried out regularly on the bathroom and precautionary measures should be taken in other not to be infected by the organisms in greywater
