GPRS Overview Of Video Pipe Inspection
Water & Sewer
Two of the most important utilities buried beneath the surface include water and sewer. Water utilities are supplied to a population from a public water system and include both potable (drinking water) as well as water for washing, cooking and waste disposal. Sewer utilities refer to utilities such as water drainage (storm water) and waste (sanitary) drainage. Damage to any of these types of utilities could mean a widespread area without clean water, or water that has been contaminated due to waste. Over 286 million Americans get their tap water from a community water system. It is crucial to recognize that water utility pipes are the only underground utility carrying a product people put into their bodies!
Some states mandate water & sewer utilities belong to the One-Call system, which ensures they will get locate requests. However, unlike the gas & oil industry, which must comply with PHMSA regulations, water & sewer pipelines do not have a national regulatory agency mandating permanent marking systems and public awareness initiatives. About 65% of all utilities are privately owned, not public, so they won’t be documented by services like 811 locating.
As an industry, significant effort has not been placed on involvement in the national damage prevention effort. This may be due to many water & sewer utilities having very small service areas compared to gas & oil, electric, and communications companies, which naturally creates a more local focus within the companies
The EPA estimates that a $744 billion investment in clean water and drinking water infrastructure is needed to meet and maintain existing public health and environmental standards over the next 20 years. The most recent Common Ground Alliance (CGA) DIRT report, which tracks damages to all buried facilities nationally, shows that installing water & sewer lines accounts for 36.7% of all damages. This makes the installation of sewer & water lines the #1 known cause of damage to the nation’s buried infrastructure. There is also a significant number of old water & sewer pipelines in the ground that are not locatable with conventional EM locators. GPR can be an alternative to locating the pipeline in many cases, but not in every case.
GPRS is capable of providing further options when locating and inspecting these critical underground utilities; Video Sewer Inspection and Video Pipe Inspection. These services have produced exceptional results in helping our customers determine if a pipe needs to be repaired or completely replaced. Our Video Pipe Inspection Services are capable of inspecting water and sewer pipes by applying several different techniques. The most efficient means of locating and inspecting these pipes occurs with using our Robotic Video Crawler Cameras (CCTV), Push Cameras, and Lateral Launch. These devices are able to inspect hard to reach and smaller pipes, previously hidden sewer lateral lines, map complete pipe and sewer systems, and provide detailed NASSCO reports regarding the interior condition of pipes. Cross bore mitigation and discovery is also a key benefit to using GPRS VPI Services.
Nationwide, our GPRS VPI team is fully equipped with the video pipe inspection equipment mentioned and ready to service/inspect your water and sewer utility project. When the GPRS Video Pipe Inspection Team is paired with our industry-leading utility locating services, you will receive the most comprehensive solution available.
- GPRS was great to work with! When we started on this project, all we had was City records of a large combined sewer line and an approximate location from our surveyors. We had GPRS use their technology to confirm the location and what they found was crucial in moving our design forward. Even the City has since praised them for providing the information and allowing them to accurately update their model."

What is Video Pipe Inspection?
Video Pipe Inspection is a method of using video to visually inspect a utility line for cracks, infractions, blockages, and other imperfections in the line. The process involves navigating a video camera through a utility line, either manually or via a remote control, which provides a video feed of the pipe’s interior to an on site monitor for viewing.
How Does Video Pipe Inspection Work?
The first step to performing a CCTV pipe inspection is to find the access point where the camera can be lowered into the utility line. Once the camera is lowered into the line, it can give a very clear picture of the condition of the line and what the inside of the utility looks like.
Why Do We Use Video Pipe Inspection Work?
There are typically four main reasons why someone uses VPI. The main uses for VPI include non intrusive inspection of pipes and conduits, discovering unknown laterals and tie-ins, identifying problematic areas caused by deterioration or poor construction and to locate other unknown blockages. The value of using it can help customers deal with damaged sewer lines and the repairs can focus on those damaged sections only, which in the long run will reduce the cost and time it takes to fix the pipe.

NASSCO is the National Association of Sewer Service Companies. NASSCO sets industry standards for assessing, maintaining, and rehabilitating underground infrastructure. Two training programs are used to certify those who are performing pipe inspection work. The Pipeline Assessment Certification Program is the North American Standard for pipeline defect identification and assessment. NASSCO’s Inspector Training and Certification Program is the standard national training and certification program which provides field construction professionals with comprehensive learning and tools to understand and inspect trenchless pipeline renewal technology.
