Abstract. Pollution of water sources as a result of inadequate sanitation is a serious issue in Indonesia. Domestic wastewater is considered as the most significant contribution to the water pollution. Centralized wastewater treatment plant systems built to serve city sanitation is costly for developing countries. Considering greywater has been practically separated from blackwater at its source of wastewater in most households in Indonesia, decentralized greywater treatment systems by adopting manmade wetlands in the level of individual household can be promoted. The manmade wetlands are characterized by specific conditions enabling simultaneous various physical and biochemical processes. This system utilized the interaction of aquatic plants and microorganism in the removal of pollutants. This paper presents the performance of a man-made wetland built four years ago on a household yard. The manmade wetland was constructed with dimension of 170x70x70cm, planted with Cyperus alternifolius aquatic plants, and filled with 40 cm gravelly sand filter media. Treatment performance of the systems was evaluated for the removal efficiency of Biological Oxygen Demand, Total Suspended Solid, Dissolved Oxygen, Oil & Fat, and Detergent. Results showed that the manmade wetland system still removed effectively the pollutants. Hence, the system still in a good performance to decrease the wastewater load discharged into the municipal drainage systems, help to recharge groundwater with better quality source, and provide aesthetic-green yard views.
