DRAINAGE PERFORMANCE EVALUATION AND MAINTENANCE OF SPEED REDUCER-YOKE VENT DRAINAGE SYSTEM BY POST-COMPLETION TESTING

Proposal and performance verification of disposer drainage stack system for super high-rise commercial buildings (Report 2)

Abstract

This study aims, through a proposal and drainage performance verification of a new disposer drainage stack system applicable to kitchen drainage systems of super high-rise commercial buildings, to obtain knowledge which contributes to the planning and design method of such a drainage system. This report describes an investigation which was carried out on the system for one year after the tenants of the building started their businesses, during which time, how kitchen wastewater loads were actually generated, load-associated variations in in-pipe pressure and contamination of the pipe were observed, and verifies subsequently the effectiveness, safety and maintainability of the system.
