초록

In this study, current sewer infiltration/Inflow(I/I) computation and application method was examined about improvement and adequacy relating to the main issues raised by the field for practitioners. The results of review about infiltration calculation method were considered to be in need of improvement at‘standards of minimum sewage calculation’. Furthermore, the results of review about I/I application method were considered to be in need of improvement at‘standards of seasonal infiltration application’and‘the relative decrease in the Annual evaluation standards’. In addition, annual I/I analysis at JC County for the four years(2009 ~ 2012) in respect of operation flow and rainfall data was conducted. The result of annual infiltration analysis, compared average daily sewage generated average infiltration rate was found in 21.95 %, infiltration by unit was found in 0.31 m3/day/cm/km and 0.12 m3/day/day, respectively. The result of annual inflow analysis, average rainfall - Inflow equations was found y = 5.499x(R2 0.793), and the average Inflow quantity by sewer extension was predicted to 0.66 m3/mm-km.
