APPLICATION FEASIBILITY OF ULTRA LOW FLOW WATER CLOSET WITH A MOVABLE DRAINAGE MECHANISM FOR DRAINAGE SYSTEM OF HIGH-RISE BUILDING(Environmental Engineering)

Abstract

The use of Ultra Low Flow Water Closet with a movable trap mechanism in houses (3 storeys at maximum) has already been approved by the former Minister of Construction. This study examines the application feasibility of the aforesaid water closet of high-rise and super-high-rise building drainage systems through experiments. Firstly, influence over the drainage performance of a drainage stack system was examined by changing the controller of the movable trap mechanism and the formation of the pipe work. Secondly, trance port performance was identified, using horizontal branch pipe work with a total length of 10m forming 5 bends. The outcomes of the study successfully demonstrated technical improvement to the standards of the existing Ultra Low Flow Water Closet.
