This study investigates use of acoustic signals to detect cracks in polyvinyl chloride (PVC) sewer pipes. Cracked sewer pipes can result in release of untreated human and industrial waste, toxic materials and debris affecting human health and the environment. The released toxic effluents can pollute water reservoirs and damage public and private property. Polyvinyl Chloride (PVC) pipes have been extensively...
Newly developed applications for condition monitoring of piping networks (e.g. sewer pipes) depend on measuring acoustic signal attenuation through tests in the field. In many cases, the exact layout of the installed pipelines is not accessible or actual installation differs from documented layout. This lack of exact knowledge of numbers and lengths of side branches (laterals) introduces a random...
Sewer piping networks are prone to damage due to aging, natural disasters, excessive traffic and chemical reactions with the contaminants and the soil. The released effluents from sewer system overflows (SSOs) can contaminate the water reservoirs, cause property damage and pose public health hazard. The SSOs are caused by blockages, breaks due to structural weaknesses and other pipe defects. To mitigate...
