Transmission Main Survey by Transient Tests: The Case of Villanova Plan in Mantova (I)

Abstract In this paper the possibility of using transients to survey a complex transmission system in the city of Mantova, Italy is explored. Transients are generated by pump trip, and the pressure signal is acquired immediately downstream of the pumping station. The pressure signal is analyzed by the wavelet transform to locate the main singularities and evaluate the pressure wave speed of the main pipe. Then a lagrangian model is carried out to evaluate the causes of experimental pressure variations. The comparison between experimental and numerical traces allows checking the efficaciousness of the procedure and diagnosing the network.
