Modelo experimental para identificação de vazamentos a partir do uso do geofone.

Abstract

The rate of water loss in supply systems in Brazil is around 37% (SNIS, 2017). This amount represents a waste of billions of reais per year. Moreover, there are constant increases in high water demands due to population increase, a factor that is still aggravated by natural drought phenomena. Given this scenario, the need for improvement in Brazilian water management and the minimization of losses, the acoustic research and leak detection methods play a central role in the search for control of the present scenario. The research was carried out with the purpose of constructing an experimental model that would assist in the use and training of the acoustic detection device, geophone, contributing to the understanding of the parameters involving the non visible leaks. In view of the results, it was observed that the device is effective, but the operator needs training skills. Variables such as depth have been understood, however, thorough studies involving other parameters are required.
