Is there a tool or device that can detect or find under ground water lines that do not have a magnetic strip?

Yes, there are several tools and devices designed to detect underground water lines without magnetic strips. Ground penetrating radar (GPR) is one such technology that uses radar pulses to image the subsurface, allowing for the detection of non-metallic pipes. Additionally, acoustic leak detection devices can identify sounds from water leaks, which can help locate underground lines. Lastly, electromagnetic locators can sometimes detect the electric field generated by water flow, aiding in the identification of buried water lines.
