| Klebsiella spp. vs Salmonella spp. | 5 | 52 | 57 | 43 | 0.026 | 0.86 | 0.56 | 0.99 |
| Aeromonas spp. vs Salmonella spp. | 3 | 82 | 85 | 15 | 0.008 | 0.57 | 0.87 | 0.99 |
| Legionella spp. vs Shigella spp. | 24 | 24 | 48 | 52 | 0.007 | 0.90 | 0.33 | 0.95 |

Samples were obtained from a total of 29 rainwater tanks and at four sampling sessions (i.e., 116 total samples for analysis of bacteria genera).
