Video Pipe Inspection Services

We Know Sewer Pipes

We'll Pin Point Pipe Defects in the Field


When conduits or pipes break, Trinity Subsurface, LLC has the equipment and experience to pin-point defects in the line on the surface. 

Video pipe inspection employs various types of robotic cameras to visually inspect pipes and other structures that could not be inspected otherwise.  Video pipe inspection can require several different tools depending on the field conditions and the type of pipe being inspected.

  1. A push camera can negotiate 45-degree turns and 90-degree sweeps.
  2. A robotic crawler is employed when access to the pipe is direct such as an opening in a manhole. 
  3. A lateral launch camera inspects sewer laterals for cross-bores.

"But in just a couple short years, the company has expanded to become a full-fledged underground utility contracting company, adding CCTV inspections, vacuum excavation and sectional point repair services."

precise observations made in real-time

A camera is inserted into the pipe and a live video feed is monitored by a Trinity Subsurface field employee. When a defect is identified, an electromagnetic transmitting device located in the camera head is triggered, allowing Trinity Subsurface Engineering to pin-point the camera location, as well as the location of the defect. 

CCTV inspection work ranges from pre- and post-construction — ensuring integrity of the pipes and looking for any roots, cracks or blockages — to emergency work responding to floods or sinkholes. 

Grease and Root Balls

Video pipe inspection services are an effective method for identifying the location of defects and lateral tie-ins within non-pressurized pipes and conduits. Our equipment has the capacity to inspect pipes ranging in diameter size from 4 inch through 72 inches. A robotic camera truck is inserted into the pipe from an available access point, such as a clean out or manhole. The robot will traverse through the pipe, allowing our professional technicians to document everything everything see along the way. 

Once a defect is observed, a transmitting device located in the camera head is activated, allowing our technicians to pin-point the location of the camera truck and thus, the location of the observed defect. This eliminates the need to excavate needlessly searching for the defect, which ultimately lowers the risk of damaging 3rd party utilities in the vicinity of the damaged pipe.

We’re all about providing the data you need to get the job done. When we perform video pipe inspection services, we’ll collect a standard set of data that includes information about the pipe, such as function, size, and material. We’ll document the heading of the pipe, as well as the entry / access point used. 

When a defect is discovered, we’ll document the lateral distance from the entry point to the defect in feet and inches. We’ll include notes regarding where the defect is located in the pipe (I.E. “Root Intrusion at 2 O’Clock”), as well as general notes regarding the extent of the damage. 

All of this information is presented in an easy to read report. The data that is reported from each pipe segment that is inspected will be contained on it’s own report. In addition to the pipe segment report, we’ll include a field map depicting all of the pipes that were inspected so it is easy for our clients to relate video footage and reports to locations in the field. 

We always want to make sure we ask our customers questions when they need video pipe inspection. The first question is what size is your pipe? For smaller than 6 inches we would recommend our push camera service. For pipes larger than 6 inches we recommend either a robotic crawler or lateral launch. While our crawler is generally used to inspect main lines, the lateral launch would be utilized when laterals or tie-ins need to be inspected. Our lateral launch has a second camera that can be launched in the lateral from the main to inspect both the mainline and laterals.
