Suitable vegetation for water treatment needs to be considered, depending on the type of water being treated, the tolerance of the vegetation, and the climatic conditions. Vegetation serves a variety of functions in CWs. It slows down the HLR, thereby increasing HRT for efficient water treatment. Large success has been reported in the usage of wetlands in farm waste-water treatment plants, with aquatic vegetation such as cattails (Typha spp.), bulrush (Scirpus spp.), and phragmites (P. australis) used to treat water. Phragmites australis is a very popular as emergent aquatic plant for waste-water treatment CWs. In addition, vegetation provides habitat to wildlife and gives the CW an attractive aspect (Brix, 1994).
