    This research examines a circular-shape constructed wetlands (CCW) system at Bedengan Camping Site (BCS) as Natural Tourism in Malang, Indonesia. There are family fun-park, shallow rivers, and camping grounds at BNT as a tourist attraction. The CW system was built in 2021 and used to treat greywater from public toilets, food courts, and cafes. This study aims to demonstrate the performance of the CW system in treating greywater to meet the standard limits of the treated wastewater. The CW was arranged in a circular shape to follow the contour of the land, and three water plants such as Canna, Heliconia psittacorum, and Equisetum hyemale planted for the CW treatment. A sampling of wastewater took place during covid-19 pandemic and after the pandemic from three sampling ports: the sedimentation tank, inlet of CCW, and outlet of CCW. The results show that the CCW system performs well in reducing organic pollutants from greywater produced by visitors and meets the domestic wastewater threshold limit as stated in the Ministry of Environment and Forestry Regulation No. P.68/2016. The average of the organic pollutant removals was higher than 90%, while the pH of the treated water changed from acid to neutral condition. It is assumed that the CW system can provide a neutralisation process of the greywater at BCS. © The Authors, published by EDP Sciences.
