The study aims to experimentally examine how the drainage performance of an apartment house drainage stack system is affected by installing a pumping toilet system for nursing care at a selectable location. This report evaluates the drainage performance of a high-rise building drainage stack system, when the toilet and other fixtures are connected through horizontal branch pipes to the drainage system and a load is applied from each fixture, and provides basic data for establishing a planning and design method of such a drainage system.
