Abstract: A method for identifying a material of a water pipe buried below ground is provided. The method includes generating controlled vibrations in the water pipe using a vibration exciter, and detecting a vibration response associated with the water pipe in response to the controlled vibrations using a vibration transducer in vibrational communication with the water pipe. The method further includes analyzing and processing the vibration response using a vibration signal analyzer to identify the material of the water pipe based on a comparison of the processed vibration response of the water pipe to a known vibration response of a known water pipe material.

Abstract: A method for identifying a frequency producing a dominant vibration response of an underground structure includes the steps of inducing controlled acoustic waves in the structure via ground, the acoustic waves varying over a predetermined frequency range, measuring vibration response associated with the structure in response to the controlled acoustic waves over the predetermined frequency range, using a measurement device in vibrational communication with the structure, detecting a dominant vibration response among measurements across all frequencies of the predetermined frequency range, and, identifying a frequency of the predetermined frequency range which produced the dominant vibration response.

Abstract: Technologies for detecting leaks in a fluid distribution system are described herein. Historical leak detection information is received from a sensor in the fluid distribution system and collected in a database. A baseline is determined from the historical leak information. Current leak detection information is then received from the sensor and the probability of a leak in the fluid distribution system is determined based on a difference between the current leak detection information and the baseline.

Abstract: To perform a non-destructive condition assessment of a pipe carrying a fluid, an actual value representative of the propagation velocity of an acoustic disturbance propagating between two longitudinally separated points on the pipe is determined. A corresponding predicted value for the propagation velocity is computed as a function of at least one wall thickness parameter of the pipe by using a theoretical model for the propagation of acoustic waves in the pipe that assumes said pipe has a finite wall thickness with a predetermined circumferential thickness profile. The wall thickness parameter is then computed by matching the actual value with the predicted value, for example, by substituting the actual value in a formula predicting the theoretical value.
