Greywater represents wastewater type which generated from kitchen, laundries, and bathroom. Disposal of untreated greywater into the water bodies can cause water contamination as greywater contains numerous substances such as a surfactant, oil, grease, organic material, solids particle, and pathogen organisms. This study is aimed to investigate the performance of the vertical sub-surface flow constructed wetland (VSSFCWs) in removing BOD and TSS from greywater which produced from a student dormitory at the State University of Malang, Indonesia. There were two of VSSFCWs lab scale as a control and a planted which have the same dimension of 0.9 × 0.4 × 0.5 m. Ipomoea Aquatica used as a plant in the planted VSSFCWs. Gravel with a size of ± 10-30 mm used as media in VSSFCWs both for control and planted VVSFCWs. The experiment was conducted in five weeks and collected triplicate sample in every three days. The average of raw greywater concentration was 48 mg/L and 99.3 mg/L for BOD and TSS respectively. While the treated greywater produced 13.4 mg/L of BOD and 8.6 mg/L of TSS for the control, 4.45 mg/L of BOD and 5.63 mg/L of TSS for the planted test. The VSSFCWs shows high removal performance of 91% BOD and 94% TSS. The quality of the treated greywater has met the standard of Ministry of Health regulation of Republic of Indonesia No. 82/2001 which suitable for toilet flushing, gardening, and groundwater recharging.
