Are you in need of specialized video cameras for a sewer and pipe inspection? Look no further than GPRS. Beyond video pipe inspection (VPI), GPRS performs utility locating, concrete scanning, facility mapping and modeling, drone imagery, and leak detection services for our clients. With all of our services GPRS offers an advantage over our competitors, and for VPI it’s our WinCan Reports. GPRS is proud to offer WinCan reporting to our Video Pipe Inspection clients. Maintaining sewers starts with understanding the sewer condition, and WinCan allows GPRS PMs to collect detailed, NASSCO compliant inspection data. Additionally, our WinCan reports include screenshots of the interior condition of the pipe segments that we inspect, as well as a video file of the complete inspection for further evaluation, documentation, or reference.
