20 Claims

1. A method for detecting cross bores involving a sewer system and a gas system, the method comprising:

generating an acoustic signal using an acoustic generator placed within an access feature of the sewer system;

listening for the acoustic signal using an acoustic receiver placed within an interior of the gas system;

analyzing received acoustic signals using the acoustic receiver; and

identifying a potential cross bore location based the received acoustic signals.
