A study of the ability of three plants extracts to treat grey water from domestic source was carried out. The plant materials used were extracts of Agave sisilana leaves, Moringa oleifera seeds and Parkia biglobosa seeds. The investigation involved the applications of the extracts the respective plants singly and synergistically at dosages of 100 mg/l, 120 mg/l and 150 mg/l to treat domestic grey water. Turbidity (NTU), pH, total dissolved solids (mg/l) electrical conductivity (µs/cm), dissolved oxygen (mg/l) BOD (mg/l) and total coliforms (CFU/100 ml) were measured using standard methods. The relative performance indices obtained showed that M. oleifera + P. biglobosa had the best performance (0.84) which was closely followed by M. oleifera alone (0.83). The least performance was recorded by A. sisilana extracts alone (0.39), The study concluded the A. sisilana, M. oleifera and P. biglobosa can serve as readily available, cost-effective, and environmentally friendly alternative coagulants and antimicrobial agents in grey water treatment.
