Resumo: The use of new materials in the sanitation industry aims to improve water treatment conditions and optimize the performance of the structures of sewage systems. Studies show that investments in sanitation are four times more effective than health. Manhole (PV) is an integral structure of the collection networks of major importance sewage because it is the sewage flow of the meeting from various facilities that are guided and follow for further processing. Non-destructive tests are widely used in modern industry worldwide to evaluate the quality and detection of changes in structure, small surface flaws, presence of cracks and other physical disruptions, being capable of detecting flaws in structures prematurely allowing constant monitoring and real time frame. The technique of acoustic emission (AE) is effective both during subsequent tests the implementation of the structure, guaranteeing their structural integrity, and in the real-time monitoring of the frame subject to the usual charging service, while performing its function without need of interrupting. To properly investigate the structure is necessary to know how the defects are and their respective acoustic activity. In this study, the acoustic emission signals generated in polyethylene manholes by variable axial deformation during loading are characterized both in time domain and in the frequency domain creating the signature of the defect.
