A-46 Study on Drainage Performance Evaluation and Design Method of Horizontal Drainage Pipe System for SI Housing : Part9. Evaluation of Combined drainage for Dirty water & domestic water load Test

Abstract

This study is aimed a grasp at the technique of performance evaluation and design,that is method of the horizontal fixture drain branch pipe system with drainage header piping applied to dwelling of SI housing.This paper focuses on performance evaluation of combined drainage for dirty water & domestic water on that system.The authors described affected by combineddrainage test an aspect of the pressure variation in the horizontal pipe, the variation of water level of the trap and characteristic of back flow as an evaluation index.
