 isolates were recovered from the raw water sample with Escherichia coli having the highest occurrence of 47.2% followed by Salmonella spp. with15.0%, Shigella spp. with 11.3%, Klebsiella spp. with 9.4% while Bacillus spp. and Proteus spp. had the least occurrences of 3.8% and 5.7% respectively. After treatment with moringa, only 17 (24%) bacteria were isolated. E. coli reduced from 47.2% to 11.8% and salmonella has no growth. The physicochemical properties of the moringa treated, charcoal sand filtered, solar heated water (MTFSH) met the WHO standard limit for portable water, showing pH of 6.9, TDS (22mg/L), temperature (26oC), hardness (100mg/L), turbidity (0.15NTU) and electrical conductivity (0.14mScm-1).

A complimentary efficacy of Moringa oleifera seed coagulant, charcoal-sand filter and solar heat for surface water treatment was evaluated, using Omoshio stream in Ado-Ekiti. The quality of the treated water was examined with bacteriological and physicochemical analyses. Sensory evaluation of the treated surface water was done using a 20-man panel and the result was statistically analyzed. The mean total bacterial count for the raw sample is 28.2 x 105CFU/ml. the mean total Salmonella/Shigella count is 12.0x105CFU/ml and the mean total coliform count is 23.2 x 105cfu/ml. Microbial load was greatly deactivated through the combined effects of moringa treatment, charcoal sand filtration and solar heating, bringing the microbial load to almost 99.9% reduction. It is observed that the mean total bacterial count decreased with 10g compared to 2.5g of moringa treated water sample. 53 (76% of the total) isolates were recovered from the raw water sample with Escherichia coli having the highest occurrence of 47.2% followed by Salmonella spp. with15.0%, Shigella spp. with 11.3%, Klebsiella spp. with 9.4% while Bacillus spp. and Proteus spp. had the least occurrences of 3.8% and 5.7% respectively. After treatment with moringa, only 17 (24%) bacteria were isolated. E. coli reduced from 47.2% to 11.8% and salmonella has no growth. The physicochemical properties of the moringa treated, charcoal sand filtered, solar heated water (MTFSH) met the WHO standard limit for portable water, showing pH of 6.9, TDS (22mg/L), temperature (26oC), hardness (100mg/L), turbidity (0.15NTU) and electrical conductivity (0.14mScm-1). The results derived from this study showed that charcoal-sand filtration and solar-disinfection complimented with Moringa oleifera seed coagulation can be recommended as a good means of eradicating water borne pathogens.
