This study compared and analyzed Night-time Domestic Flow Evaluation, Water Use Evaluation and BOD Evaluation by conducting the investigation of flux and water quality for one year from April 1, 2013 to March 31, 2014 targeting three treatment basins among Build-Transfer-Lease(BTL) sections of sewer pipe maintenance that was carried out nationwide regarding BTL section of sewer pipe maintenance in Sangju-si in 2005 aiming at providing basic data of installation status and maintenance of separate sewer pipe as the investigation and analysis of infiltrated and influent water at the separate sewer pipe maintenance area. As the results, it was judged that it was impossible to analyze Water Use Evaluation because the use of underground water was huge considering local characteristics of Sangju-si and the analysis of infiltrated and influent water (I/I) that is the method of investigating and analyzing night-time domestic flow and the status of night-time domestic flow of residence center for each administrative district and treatment basin was used in this study because it was judged that it was impossible to apply the characteristic factor during base period due to the change of water-collecting cycle and method when it comes BOD Evaluation. As the results of analysis, it was shown that the ratio of infiltrated was average 17.3% and infiltration rate was 0.29m3/d/cm/km in case of Jeungchon treatment basin, infiltrated was average 23.5% and infiltration rate was 0.61m3/d/cm/km in case of Mansan treatment basin and infiltrated was average 11.3% and infiltration rate was 0.03m3/d/cm/km in case of Shinheaung treatment basin. To summarizing analysis results of each treatment basin, the area with the lowest infiltration was Shinheaung treatment basin and the area with the highest infiltration was Mansan treatment basin among the investigated areas, and the average of investigated area was analyzed as 0.31m3/d/cm/km.
