adequate treatment facilities due to the high cost of conventional treatment technologies. The negative impact of wastewater on the environment calls for the need to develop alternative and economical methods of treatment/utilization. Wastewater reuse is also animportant strategy for conserving water resources, particularly in areas suffering from water shortage (Kivaisi, 2001). Constructed wetlands have been reported as cheap technologies and can treat various forms of wastewater of varying strength. They do not need complicated maintenance like other conventional wastewater treatment technologies such as activated sludge system (Stefanakiset al., 2011; Uysal, 2013; Li et al., 2013).
