GPRS Video Pipe Inspection services with the SiteMap® Sewer Layer provided a stormwater compliance and management company with the insights needed to keep a citywide project running ahead of schedule.
The city of St. Louis, Missouri, was planning to tie a private sewer system into its public infrastructure. The city hired Stormwater LLC to examine the current conditions of the sewer system. They had the current as-builts but didn’t know the state of the pipes’ interior.
Stormwater LLC reached out to GPRS and Project Manager Brendan Koziol took on the task of investigating the underground pipes. All GPRS VPI Project Managers are NASSCO-certified and are trained to provide clients with comprehensive, interactive reporting that details every inch of their pipes to help them plan repairs, maintain system integrity, and mitigate risk.
Koziol deployed a remote-controlled sewer inspection crawler and push-fed sewer scope to document the conditions of the sewer system. These crawlers feature CCTV cameras to record the conditions within storm and sanitary sewer lines.
While investigating one of the pipes, there was an equipment malfunction that occurred and cut a video short. Nevertheless, Koziol was quickly able to correct the issue.
“A weird technical malfunction caused video interruption in one of the pipe segments,” Koziol explained. “Since I was going to be back in the area, the customer added additional linear feet for me to investigate, and I was able to capture all the pipe conditions, including those from the interruption.”
Upon the completion of the investigation, Koziol sent the client a NASSCO-compliant WinCan report that ranked every defect by severity and identified them with photo and video evidence.
Because of Koziol’s efforts, Stormwater LLC was able to send the reports to the city earlier than expected.
Koziol uploaded all the data, reports, and videos to the SiteMap Sewer Layer, a new feature in SiteMap that securely stores VPI reports and videos. With the results in the SiteMap Sewer Layer, the client can access all the reports and videos in one easy-to-use interface for this project and future O&M projects.
“They thought it was pretty cool with what we could do with SiteMap,” Koziol explained. “With the deliverables that we had, they definitely want to use us going forward with SiteMap and with how timely we were on site.”

FREQUENTLY ASKED QUESTIONS
What size sanitary sewer and stormwater pipes can GPRS inspect with its Video Pipe Inspection service?
Our elite, NASSCO-certified VPI Project Managers have the capabilities to inspect pipes from 2” in diameter and up.
Can you locate pipes in addition to evaluating them for defects?
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.
