By treating the raw effluent before entering the catchment area could help in reducing the pollution and improve water quality. Constructed wetland is a method of natural wastewater treatment being used especially in urban area by using wetland vegetation. Waste water treatment by wetlands vegetation have a few advantages due to its cost efficient and required less technology as well as improve surface water quality and effluent discharged to catchment area. Apart from that, the aesthetic value of the wetland attracted wildlife to come and make their new habitat especially for birds and insects. With the proper design, this wetlands have a potential as public parks for the urban dwellers mainly as the decreasing of total number of green area due to rapid urbanization in urban area.
