Trinity Subsurface, LLC offers Video Pipe Inspections “VPI” as a part of our Pipe Services Division. There are several different types of pipe inspections that can be performed; the four types of inspections Trinity provides are mainline inspections, lateral launch inspections, culvert walking inspections, and manhole inspections. Our inspections are extended to several types of systems, including storm sewers and sanitary sewers. Trinity utilizes NASSCO’s PACP, MACP, and LACP certified specialists to perform all pipe inspections; these specialists monitor every pipe’s structural integrity, construction features, maintenance conditions, and operational conditions. Below is a more in depth look at what Trinity’s pipe services VPI team can do for you.

Mainline pipe inspections, at Trinity, offer a comprehensive understanding of how a system’s mains are performing. Mainline inspections provide general conditions for each pipe, this includes footage of pipe conditions, pipe diameters, material, water levels, and joint spacing.  This type of inspection also monitors for structural data such as cross bores, joint separation cracks, fractures, breaks, holes, collapses, and much more. Another detail this inspection provides is the maintenance data, this can include inflow and infiltration, root build up, grease attachment, surface conditions, odors, and any vermin in each pipe. Mainline inspections are a great way to identify the conditions of a single pipe or of an entire system of mainline pipes. For some large diameter pipes, a culvert walking inspection is recommended. This inspection allows for all the same data to be collected as a mainline inspection. Safety is of the main priority with all of our inspections and services; culvert walking uses several extra safety mechanisms in order to provide a safe working environment, which includes air monitoring, spotters, flow control, respirators, infall and outfall identification, and much more.

Lateral launch pipe inspections are similar to our mainline inspections, but provide an inspection of each lateral along all designated mains. This allows for our clients to identify, rehabilitate, update, and improve existing laterals. This inspection is great for identifying problematic laterals tying into a main line.

Manhole inspections are also provided at Trinity. These inspections utilize a camera that takes 360 degree imaging, point cloud, and a depth finder. Trinity will identify all conditions from the lid to the bottom of the channel.  Manhole inspections are a great way to find unwanted inflow and infiltration into a system.

Trinity’s clients request for a pipe inspection for several reasons. Some of the many reasons are as follows: Maintenance Related, Inflow and Infiltration, Routine Assessment, and Pre/Post installation surveys. Every pipe inspection project can be paired with Trinity’s other services; Trinity can identify the location of a pipe using its EM equipment. For Quality Level A data, vacuum excavation can be used; this is for when our customers need eyes directly on the pipe. Pipes are often in need of some tlc, and this is where our pipe maintenance team will help flush the system, remove grease, remove roots, and much more. All pipe inspections are paired with a field sketch and a NASSCo certified report; every video is placed into a digital photo album, where our customers are free to download any and all pipe videos. Trinity looks forward to working with you to solve your pipe service and underground utility needs!
