How Truax Corporation Transformed Manhole Inspections with TREKK360 & SewerAI
Truax Corporation is a family-owned infrastructure services company founded in 1958, serving 4 states across New England with over 2 million feet of CCTV sewer inspections per year. For decades, their manhole inspection process relied on measuring tape and top-side photos — a slow, manual workflow that limited what they could deliver to clients. With TREKK360 and SewerAI, Truax now inspects 100+ manholes per crew per day and delivers inspection reports and 3D models in hours, not days.
About Truax Corporation
Truax Corporation is a family-owned infrastructure services company founded in 1958 and headquartered in North Attleboro, MA. With more than 65 years of experience, Truax serves clients across 4 states and performs approximately 2 million feet of CCTV sewer inspections every year. As one of New England's most trusted names in underground infrastructure, Truax has built its reputation on reliability — and today, on innovation.
The Challenge
Mainline inspections were a strength. Manhole inspections were a different story.
The old workflow required manual data entry in the field, measuring tape for every defect and dimension, and top-side photos that gave engineers very little to work with. Video from rotating cameras produced distorted, unreliable 3D models. Reports took days to turn around.
Jamie Truax, who leads operations and is driving the company's modernization, described the experience:
"Back in the day it was definitely a lot more complicated — we had to manually type all the field info into software, measure everything by hand, and take pictures manually. It was a huge headache and took up a lot of downtime."
The process was inefficient enough that Truax avoided manhole inspection work altogether unless a contract required it.
The Solution
Truax paired TREKK360, a motorized self-leveling manhole inspection camera, with SewerAI's automated processing platform. Together, they replaced a fragmented manual process with a workflow any crew member can run.
TREKK360's self-leveling descent keeps footage stable from start to finish — no rotation, no distortion. That footage uploads directly to SewerAI, which handles defect coding, measurements, and report generation without manual input.
In the field, the process is straightforward: power on, drop the camera in, pull it up, move to the next manhole. No specialist required. No truck setup, no calibration, no post-processing backlog.
"Now it's simple — turn the camera on, drop it in, pull it up, and move to the next one. We can get over 100 a day with your equipment," said Jamie.
Where Truax once delivered a top-side photo and basic inspection notes, they now provide fully interactive 3D models backed by complete 360° video.
"It used to be just a top-side picture, which you could barely see anything from. Now, it's a whole 360° video of the entire manhole."
Engineers can zoom, pan, and take precise measurements of defects, pipe diameters, steps, and infiltration directly from the model — and reports are ready in hours.
The Results
Faster daily output. Truax went from avoiding manhole work to completing 100+ inspections per crew per day, without adding headcount or requiring specialist operators.
Better client deliverables. Interactive 3D models and 360° video have become a differentiator in client presentations — engineers now request them by name.
Shorter turnaround times. SewerAI's automated processing means reports and models are delivered in hours, not days, keeping projects on schedule.
Stronger bid competitiveness. The combination of speed, quality, and lower operational overhead gives Truax a clear advantage when competing for manhole inspection contracts across New England.
Better Data, Better Deliverables
Beyond speed, TREKK360 + SewerAI together deliver a quality of data that simply wasn’t possible before. Every manhole inspection now produces full 360° interior video, giving engineers a complete visual record of the structure’s condition. The precise 3D models generated by SewerAI’s platform are accurate enough for engineers to take real measurements — not just reference images.
The accuracy of those models comes down to how the camera moves. As Jamie Truax explained:
“Other cameras rotate on the way down, and that messes up the model. With TREKK360, it’s dead-straight the whole way—the models come out perfect.”
These interactive deliverables set Truax apart in a market where most competitors are still handing clients PDFs with a handful of photos. For municipalities and engineers who expect more, Truax now has the tools to deliver it.
For a company with more than 65 years of history, Truax Corporation’s embrace of TREKK360 and SewerAI is a testament to what it takes to lead in a competitive industry. By pairing deep field experience with modern inspection technology, Truax is not just keeping pace with the demands of New England’s infrastructure market — they’re setting the standard. TREKK360 combined with SewerAI gives Truax the speed, accuracy, and deliverable quality to compete and win, while continuing to serve the municipalities and clients who depend on them most.
