Abstract
In this paper, a simulation was carried out to ascertain the status of water level rise and drainage in the manhole according to sewage inflow. Simulation was performed on five cases by combining 100%, 50% and 0% of sewage flowing in two sewer pipes. In case 3, which has the largest influent flow rate, the influent flow rate is 1,314 liters/ min more than the outflow flow rate, and when the maximum duration of inflow flow is 15 minutes (900 seconds), the water level in the manhole is increased by 2,400 ㎜. In the case of 100% and 0% of sewage inflows to the inflow sewer pipes (D400 and D900), 100% of the inflow sewage is discharged and there is no rise of the water level in the sewage manholes.
