This study aims, through a proposal and drainage performance verification of a new disposer drainage stack system which is applied to kitchen drainage systems of super high-rise business buildings, to obtain knowledge which contributes to the planning and design method of such a drainage system. The first report proposes a new disposer drainage stack system which employs the combined use of speed reducing fittings and a yoke vent pipe and reports on the application of the proposed system to an actual building. The report then aims to understand, at a pre-completion stage, the drainage performance and vent characteristics of the proposed system.
