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 109 cfu/ml to 8.7 x 109 cfu/ml, total coliform plate count ranged from 3.8 x 109 cfu/ml to 7.1 x 109 cfu/ml, total SalmonellaShigella plate count ranged from 3.0 x 109 cfu/ml to 4.6 x 109 cfu/ml and total fungal plate count ranged from 3.4 x 109 cfu/ml to 5.8 x 109 cfu/ml. the bacteria isolated and their percentage occurrence were E.coli (16.67%), Salmonella spp (16.67%)., Shigella spp(8.33%)., Pseudomonas spp (12.5%)., Bacillus spp. (12.5%), Klebsiella 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 Aspergillusflavus (36.36%). The ANOVA, P<0.05 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.
