Abstract: Background and Objective: The use of floating macrophytes in stabilization ponds for the secondary treatment of effluent has become popular in recent years. In this study the performance of two macrophytes: Typha orientalis and Sorghum arundinaceum in the phytoremediation of municipal runoff wastewater was investigated in constructed wetland ponds. Materials and Methods: The runoff wastewater was characterized using standard methods. The wetlands were continuously fed with municipal runoff wastewater while the treated effluents were collected and analyzed at 5 days interval for a period of 29 days. Results: Overall, the results of the usage of the two macrophytes revealed that Typha orientalis showed higher efficiency in the removal of parameters including turbidity (73.3%), sodium was reduced from (74.68%), iron was reduced (98.12%), phosphate was reduced (94.11%) and BOD reduced (97.62%) while Sorghum arundinaceum was more efficient in the removal of calcium (12.3%), magnesium reduced (18.1%), potassium reduced (30%), nitrate reduced (98.02%) and lead reduced (95.24%). Worthy of note were iron, nitrate, phosphate, lead and BOD which achieved between 94 and 98% removal efficiency. A close examination of the roots of the two macrophytes at the expiration of the experiment revealed that most metals were accumulated to the organ unlike other organs such as the leaves and stem which is mostly due to the possession of root air as the absorption organelle in the roots. Conclusion: This study further indicated that Typha orientalis and Sorghum arundinaceum both have the potential to be used in the phytoremediation of municipal runoff waste waters and their further usage is encouraged.
