Coaxial sensor array system for subsurface anomalies detection

A method for subsurface anomalies detection in a water distribution network (WDN), comprising:

• obtaining a coaxial sensor array system, comprising:
• at least one hydrophone;
• at least one hydrophone mount configured to house the at least one hydrophone;
• a pressure transducer mounted in line with the at least one hydrophone and configured to measure pressure of a water column within which the at least one hydrophone is submerged;
• a pressure transducer mount implemented as a disc configured for fitment of the pressure transducer and having galleries configured to lead the water column from fie WDN to the pressure transducer;
• an electrical connector configured to connect communication cables to the pressure transducer;
• a sensor housing configured to house the at least one hydrophone and the pressure transducer;
• and
• an end cap configured to seal a back end of the coaxial sensor array system and further configured to allow communications to pass through into a watertight shielded flexible conduit;
• and
• acquiring data from the coaxial sensor array system to detect subsurface anomalies in the WDN.
