Water quality on earth is depleted due to over increasing human development activities that over exploits and affect the quality and quantity of the water resources. The rapid urbanization has resulted in pollution of fresh water bodies due to increase generation of domestic waste, sewage, industrial waste etc. This study investigated the effectiveness and feasibility for Horizontal surface flow constructed wetland/Root Zone Unit which was constructed by Environmental Planning & coordination organization (EPCO) at Ekant Park, Bhopal. In present study samples of wastewater from Inlet and Outlet of Root Zone System situated at Ekant park, Bhopal (M. P.) were collected quarterly from June 2011 to May 2012. Some physico-chemical parameter namely dissolved oxygen (DO), biochemical oxygen demand (BOD), chemical oxygen demand (COD), nitrate and phosphate were analysed using standard methods. The result obtained indicates that the Root Zone System works effectively and treated water can be used for recreational activities like washing clothes, fishing, swimming, irrigation etc.
