This work was carried out to evaluate the feasibility of the method GPR (Ground Penetrating Radar) method to locate steel, cement-amianthus, PVC and cast iron pipes of several diameters, used by the Companhia de Saneamento do Pará (COSANPA) for water supply to the population of the urban area of Belém-Pará. To achieve this goal 14 profiles were performed at 6 distinct sites of Belém's urban area, in order to identify 13 targets, using the of 200 MHz and 400 MHz antenna, commonly used in this type of survey. The radargrams obtained with GPR allowed to identify almost all targets. surveyed. Only 3 of the 13 targets were not fully identified, leaving out only the targets of PVC of small gauge (50 mm and 75 mm). After the study, we concluded that the GPR method is very effective in this type of application and its use has great value in the location of the water supply network, what should greatly facilitate the work of expanding the network, as well as its maintenance.
