Abstract: The microbial evaluation of drinking water stored in homes have become necessary as the water could be contaminated by pathogens. Questionnaire administration was done, followed collection of one hundred and eighty stored drinking water samples from homes having no toilet/water facilities and homes with toilet/water facilities. Microbial analyses reported a mean and standard deviation counts of heterotrophic bacteria, Salmonella, Shigella, Vibrio, heterotrophic fungi, Staphylococcal, Pseudomonads, fecal coliform and total coliform bacterial as 1.6 ± 5.8 x 103, 2 ± 1.0 x 102, 0 ± 0.0, 1 ± 1.2 x 102, 0 ± 0.0, 1 ± 1.1 x 102, 0 ± 0.0, 2 ± 2.8 x 102, 6 ± 3.2 x 102 CFU/ml respectively for homes with toilet/water facilities, while for homes without toilet /water facilities, the counts were 2.8 ± 9.8 x 103, 4 ± 1.2 x 102, 0 ± 0.0, 3 ± 4.6 x 102, 1 ± 1.2 x 102, 6 ± 8.6 x 102, 0 ± 0.0, 3 ± 1.5 x 102, 1.2 ± 9.2 x 103 CFU/ml for heterotrophic bacteria, Salmonella, Shigella, Vibrio, heterotrophic fungi, Staphylococcal, Pseudomonads, fecal coliform and total coliform bacterial respectively. A total of seventy (70) isolates belonging to five (6) genera namely: Staphylococcus aureus, Vibrio spp, Salmonella spp, Escherichia coli, Klebsiella spp and Candida spp were isolated and identified biochemically. The isolates with their prevalence from water samples from homes with water and toilet facilities are Staphylococcus aureus 34%, Vibrio spp 3.4%, Salmonella spp 20.6%, Escherichia coli 31%, Klebsiella spp 10.3%, and Candida spp 0%, while Staphylococcus aureus 34.1%, Vibrio spp 9.7%, Salmonella spp 21.9%, Escherichia coli 26.8%, Klebsiella spp 4.8%, and Candida spp 2.4% were noted for homes without toilet and water facilities. Thus, stored water is challenged by poor storage containers, unhygienic sanitary practice and ignorance, as the water samples did not meet the WHO permissible bacteriological limits for drinking water. It is recommended that households develop an altitudinal interest in water security through the practice of good hygiene.
