PT.X has a Wastewater Treatment Plant (WWTP) with a capacity of 10000 m 3 /day, but the average daily discharge from 2018 until the beginning of 2019 was 4100 m 3 /day. Based on this, idle capacity occured at the WWTP of PT.X. This study aims to determine the effect of idle capacity on the quality of wastewater treatment at the WWTP of PT.X. Data collected included the discharge and waste water quality of each unit. Unit sampling was done at four points using the grab sampling method. Sample testing was carried out in a laboratory. The results of sample testing of PT.X WWTP effluent showed that the efficiency for each unit was very small, for the first settling tank unit the parameters of BOD and COD had efficiencies of - 123% and -139%, respectively. Based on that, it was concluded that idle capacity affected the removal efficiency for each unit so that processing was not optimal.
