Stream of Kampung Bugis has a vital role for society of Karang Anyar, Tarakan, East Borneo as drinking water resource. However, this river is also as a sink of waste water from households around it. As mentioned in the Government Regulation of Ministry of Environment No. 1 of 2010, to monitor the water quality of the watershed of Kampung Bugis, the determination of Pollutant Load has been conducted by QUAL2K environment modeling. The impact of waste disposal and sewage treatment plan due to population growth in order to keep the water quality meets the Class 1 of Water Quality Standard (Government Regulation No. 82 of 2001) has been simulated. The simulation was performed using water quality and watershed hydraulics data analysis results as the primary data. Segmentation of the river is divided into 19 reach based on the appropriate distance and topography of the river. Present conditions that determined through Pollution Index and the number of waste are calculated using Pollutant Loads analysis. The simulation results are calibrated using trial and error method then being examined by U Statistics Test method. The increase discharge of domestic wastewater is calculated in accordance to the population growth from 2014 to 2018. The scheming of wastewater treatment was simulated with effectiveness from 20% to 80%. Pollutant Index gives the result that the river is 'lightly polluted' and receive Pollutant Load 0.24 kg/year of DO
