Abstract

The study involved the measurement of flowrate and BOD in the Yeoju area and analyzed annual sewerage data by the I/I analysis technique which is common in Korea. The results of this study are as follows. The I/I for the Y-1 site before maintenance and after the completion of the whole process was reduced from 62% to 16.1% respectively with respect to maximum sewage flow per day. The average quality of water increased. The study measured the Y-2 site from a point of time corresponding to an 80% process rate and its I/I rate went up a little from 8.5% to 11.5%. At the Y-3 site, the I/I rate went up a little from 11% to 13.8%, while little change was noted in the average water quality. At the Y-4 site, the I/I rate was reduced from 43% to 16.9% and its average water quality went up. At the Y-5 site, the I/I quantity went up a little however its average water quality also went up largely. Therefore, it was concluded that the Y-5 site showed great improvement due to the sewer pipe maintenance.
