In order to accurately find out the location of water infiltration points in the sewage network,different water quality detection methods are used for the detection of non-external water infiltration points,based on the ac-tual case of the integrated design and construction project of a sewage collection system drainage pipe network in Nanjing,this paper analyzes the source of external water in the sewage pipe network,and provides a quick method for the investigation,detection and identification of water infiltration points in the sewage pipe.
