| Outline of Final Research Achievements |
The following matters have been clarified, which contribute to planning and designing a piping system for a building drainage system with a water-saving toilet installed thereto, in terms of ensuring hygiene and safety. ① The prediction of carrying distances of waste, toilet paper, etc., in relation to the decline of carrying performance in the horizontal drainpipe, followed by the development of a simulation tool conducive to piping design support. ② The experimental evaluation of how a piping system affects the drainage performance of a drainage stack system, followed by the clarification of applicability of a water-saving toilet to the piping system. ③ The clarification of how the speed of external wind in the stack vent pipe (vent cap) and ventilation facilities affect the trap of the water-saving toilet.
