Underground Sewer, Storm & Pipe In-Line Crawler Services

Rapid Response - Nationwide Service
[need phone number]

Video Pipe Inspection (CCTV) is a sewer inspection service using industry-leading video cameras to prevent problems by inspecting underground water, sewer lines and lateral pipelines. Our NASSCO certified technicians can locate clogs, investigate cross bores, find structural faults and damages, and conduct lateral sewer line inspections.

Lateral Inspection & Mapping

A lateral launch sewer inspection allows for a closed-circuit television (CCTV) video inspection of pipes, including mainline and lateral pipelines, and is ideal involving situations that do not allow for a typical visual inspection. During the process, a pipe is inspected from the mainline to the lateral searching for cross bores, pipe defects and structural issues.

Cross Bore Prevention & Mitigation

Cross bores are dangerous and unintended intersections of utility lines. Cross bores can cause backups in the sewer lateral, damage the structural integrity of a pipe, or even cause severe explosions. VPI services can prevent gas line cross bores and is critical to minimize the risk of property damage, injury and even death. Learn More

Sewer & Water Inspections

GPRS Video Pipe Inspection services can help discover a collapsed sewer lateral, duct, or an unknown blockage in a pipe. This service is a non-destructive option that limits project delays and budget overruns by locating the exact impediment in your water or sewer line including bellies, collapses, tree roots, lateral taps, cross bores, or other damages.

Water & Sewer Mapping

Our utility locating services are enhanced by our ability to discover, inspect, and map water and sewer systems by using robotic video pipe cameras, push cameras, and lateral launch cameras. Our VPI services ensure you can receive a comprehensive map of your sewer system including hard to discover elements like lateral lines.

Manhole Inspections

Manholes are more complex structures than typical pipes. GPRS Video Pipe Inspection Project Managers will gather detailed information to fully document all defects, determine condition of the manhole, and provide the specific information needed to recommend corrective action.

U.S. infrastructure stats

In the U.S., there are over 800,000 miles of public sewers and 500,000 miles of private lateral sewers connecting private property to public sewer lines. Each of these conveyance systems is susceptible to structural failure, blockages, and overflows.

Approximately 50% of annual expenditures, in the wastewater sector, go to operation and maintenance.

There is roughly 1 million miles of potable water piping across the country. With many of these pipes having been installed in the early mid-20th century, it is no surprise that an estimated 240,000 and counting water mains break per year.
According to the ASCE, the total infrastructure budget needed to repair and upgrade our wastewater system is estimated at $150 billion.

Sanitary sewer overflows are due to blockages, line breaks, sewer defects that allow water to overload the system, lapses in sewer system operation and maintenance, power failures, inadequate sewer design, and vandalism. EPA estimates that there are at least 23,000 to 75,000 sanitary sewer overflows per year.

Detailed Mapping

GPRS Project Managers not only inspect the interior condition of water pipes, sewer pipes, sewer laterals and manholes – they can provide a map of their location. The GPRS Deliverables Department can provide detailed GPS overlays and CAD files.

Video INspection Files

Our detailed WinCan/Nassco reports contain screen shots of the interior condition of the pipe segments that we inspect. Our Project Managers will also provide a video file of the complete inspection for further evaluation, documentation, or reference. Learn how Video Pipe Inspection works
