Utilities are installing more PVC and HDPE water mains, but these non-metallic pipes can be difficult to locate before excavation. This article explains why electromagnetic methods often struggle, where acoustic locating fits, and how utilities can reduce risk in the field.
Project Profile: Locating a Large-Diameter Concrete Water Main in Clovis, California
In Clovis, California, Solinas Technologies helped locate a difficult large-diameter concrete water trunk main where soil conditions limited GPR and traditional electromagnetic locating methods faced challenges. Using acoustic vibration rather than electrical conductivity, the SonicFinder 1000 provided a practical surface-based workflow for tracking the pipe alignment through a difficult section.
