Abstract
This report describes a commercial disposer drainage stack system installed to an approx. 100 m tall super high-rise experimental drainage tower, and the examination of how large amounts of waste drained from the kitchen of the tower (kitchen waste) affects the drainage performance of the stack and the carrying performance of the house drain. The report also aims to acquire, on the basis of the experiment results, useful technical knowledge necessary for the actual planning and design of a disposer drainage stack system which is used specifically for real super high-rise buildings for the business use.
