Video Pipe Inspection Services

We Know Sewer Pipes

We'll Pin Point Pipe Defects in the Field


When pipes break, Trinity Subsurface, LLC has the equipment and experience to pinpoint defects in the line.

Video pipe inspection employs various types of cameras to visually inspect pipes and other structures. Often times, sewer and sanitary lines are not fit for human observation. The following tools are helpful alternatives in understanding what underneath:

  1. A push camera can negotiate 45-degree turns and 90-degree sweeps with small diameter pipes.
  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."

Eliminate Guesswork with technical expertise.

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 within the camera head is triggered, allowing Trinity Subsurface, LLC to pinpoint the location.

CCTV inspection ensures the integrity of pipes by observing any roots, cracks or blockages. This is helpful for both pre and post construction. In addition, field employees conduct 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 conduct excavation, searching for the defect.

Trinity Subsurface, LLC provides comprehensive data including: 

  1. Pipe function
  2. Pipe size
  3. Pipe material
  4. Heading of pipe
  5. Entry and access point of pipe

When a defect is discovered, field employeees document the lateral distance from the entry point to the defect in feet and inches. This includes 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, categorized by pipe segment. In addition to the VPI report, we’ll include a field map depicting all of the pipes that were inspected. This makes it easy for our clients to relate video footage and reports to locations in the field. 

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. .
