Abstract

Combined sewerage is the most widespread method of wastewater management in the world. Sewage and rainwater are discharged through a combined piping system, which affects overloading the sewer networks during extreme rains. This method of wastewater disposal is the oldest type of sewerage. At present, this method is described as less suitable in opposite to rather on the construction of a divided sewerage system, where wastewater and rainwater flow through separate pipes. The main disadvantage of the combined sewer overflow chambers is the possible leakage of contaminants into the recipient. In the Slovak Republic, combined sewer overflow chambers are most often used to efficiently manage and separate rainwater. In this paper, we focus on the most commonly used types of chambers, emphasizing the efficiency of their operation. The most commonly used relief chambers are with a high overflow edge, on which rakes are placed to catch floating waste. These combined sewer overflow chambers are then divided according to the location of the overflow edge into three basic types: with a front overflow, with a side overflow, and with a double-sided side overflow.
