In this study, we performed 8 times of water quality sampling and continuous measurement of flow to identify wastewater flow characteristics for wastewater treatment basins of Namtangju city. The field survey has been conducted 6 times in dry weather period and 2 times in wet weather period. Each survey conducted 24-hr water quality sampling in the interval of 2-hr.From the analysis of flow data and water quality data,the following conclusions can be drawn. For Namyangju-1 station,which represents residential and commercial mixed area,flow rises early in the morning before office-going hour and moves up and down within narrow range, and lasted after office-leaving hour,resulting from continuous commercial activity.In case of Namyangju-5 station representing community and Namyangju-6 station representing residential area, the flow immediately falls down after rising in the morning and later rises again at the office-leaving hour, and arrives at peak flows around late evening.
