Abstract
In a conventional storm overflow chamber of a combined sewer system, inflowing floating debris do not flow into an intercepting pipe in a rainy weather, and flow out to a public water body, causing a water pollution in the public water body. According to a vortex flow type water surface control device for a draining device of the present invention, a control plate () higher than at least a separating weir () is provided between an opening of an inflow pipe () and an opening of an intercepting pipe () in a storm overflow chamber of a combined sewer system. Moreover, a guide wall () higher than at least the separating weir () is provided along the separating weir between the opening of the inflow pipe () and the separating weir ().
