Video Pipe Inspection or VPI is a sewer inspection service using CCTV video cameras to mitigate or prevent infrastructure damage by inspecting underground water, sewer lines, and lateral pipelines. GPRS's NASSCO certified technicians can locate clogs, investigate cross bores, find structural faults and damages, and conduct lateral sewer line inspections.

Yes, we offer lateral launch capabilities as part of our standard Video Pipe Inspection services.

GPRS is proud to offer WinCan reporting to our Video Pipe Inspection clients. Maintaining sewers starts with understanding sewer condition, and WinCan allows GPRS Project Managers to collect detailed, NASSCO-compliant inspection data. GPRS Project Managers not only inspect the interior condition of sewer pipes, laterals, and manholes – they can also provide a map of their location. The GPRS Mapping & Modeling Department can provide detailed GPS overlays and CAD files. Our detailed WinCan/NASSCO reports contain screenshots of the interior condition of the pipe segments that we inspect, as well as a video file for further evaluation, documentation, and/or reference.

Our elite VPI Project Managers have the capabilities to inspect pipes from 2” in diameter and up.

Yes! Our SIM- and NASSCO-certified Project Managers use VPI technology equipped with sondes, which are instrument probes that allow them to ascertain the location of underground utilities from an inaccessible location. This allows them to use electromagnetic (EM) locating to map sewer systems at the same time they’re evaluating them for defects.
