BREAKS, DEFECTS & CROSS BORES.
WE FIND THEM.
CCTV Video Pipe Inspection
Video Pipe Inspection (CCTV) is a sewer inspection service that uses industry-leading remote video cameras to assess conditions and prevent problems in water, sanitary and storm sewer, and lateral pipelines. Our NASSCO-certified technicians scope your sewers to locate clogs, identify cross bores, find structural defects & damages, and conduct lateral sewer line inspections.
GPRS is the sewer inspection company you can trust to provide you with comprehensive, interactive reporting that details every inch of your pipes to help you plan repairs, maintain your system integrity, and mitigate risk.
Cross bore Mitigation
More than one million cross bores – unknown & unintentional breaches of sewer lines, water lines, and other utilities – exist in the U.S. subsurface infrastructure, and more are added every day.
They cause sewer lateral backups, impact the structural integrity of pipes, and can cause severe damages that include fatal explosions. Hiring GPRS to conduct a video pipe inspection (VPI) ensures that you can find and repair existing cross bores, and prevent new ones by providing contractors with the comprehensive subsurface sewer infrastructure map they need before excavating or installing lines with trenchless technology.
Mainline Inspections
850 billion gallons of untreated sewage is discharged into U.S. waterways annually. That number does not account for untreated wastewater that leaches into the soil in the event of a cracked, broken, cross-bored, or defective pipe.
GPRS deploys sturdy, robotic mainline crawler CCTV cameras to assess pipe conditions, document all defects, laterals, etc., and map your mainline sanitary and/or storm sewer infrastructure as part of your NASSCO-certified video pipe inspection. Your WinCan VPI report and utility map are securely delivered and accessible 24/7 via SiteMap®, our proprietary project & facility management application. You receive a complimentary SiteMap® Personal subscription when you hire GPRS.
Manhole Inspections
Manholes are more complex structures than a typical pipe, so they require special attention to detail. Your GPRS Project Manager will utilize a variety of complementary technologies to gather detailed information, document all defects, and accurately document existing conditions so that you have the information you need to make repairs, maintain your infrastructure, and mitigate risk.
Sewer Lateral Inspections
Once we have assessed conditions and mapped your mainline water and/or sewer lines, GPRS will investigate all of your lateral lines with a lateral launch camera or a push camera (rodder) to document existing lateral line conditions, locate and report any cross bores, and map your entire water or sewer infrastructure.
Water & Sewer System Mapping
GPRS VPI services enhance a utility locate or full-site scan because we not only find the pipes, we deploy robotic sewer scope cameras, push cameras, lateral launch cameras, and additional technologies to inspect them, document their existing conditions in an interactive, NASSCO-certified report, and include them in a comprehensive, layered utility map, delivered digitally via SiteMap® for your use, 24/7.
Annual Inspection Programs
Subsurface infrastructure is a complex and ever-changing world – a world that you cannot see without the proper tools and training. That’s why GPRS strongly recommends sewer system inspections every other year to update your existing condition documentation, find new breaks, cross bores, and defects, and protect your system, facility, and community.
NASSCO Reporting
All GPRS VPI Project Managers are NASSCO-certified in PACP, LACP, and MACP, along with our required Subsurface Investigation Methodology (SIM) certification, so they are experts in locating, identifying and mapping complex sewer systems, and categorizing pipe defects to provide comprehensive reporting for your needs.
GPRS employs WinCan software in concert with our sewer scope technologies to provide interactive, NASSCO-certified existing condition reporting. GPRS reports include photos and video of each pipe defect, mapped and categorized by type and severity to provide a complete sewer system overview, so that you can repair, maintain, and plan effectively

Utility Locating
On average, 65% off all utility lines – and sewer pipes – at any job site or facility are privately owned.
Your state’s One Call (811) system will contact their partner utility companies, who will provide you with the approximate location of all their lines within your excavation area. It’s important to remember, however, that not all buried utilities are registered with 811. Ensure you don’t suffer a dangerous and expensive utility strike when you dig or drill by hiring a utility locating and sewer inspection company that can provide you with a comprehensive utility locate that accurately maps all underground utility lines.
Dye Tracing
Dye tracing, also referred to as dye testing can help you determine which variety of sanitary and storm sewer lines you have (combined or separated), the direction of your flow, help locate illicit releases, and determine whether there is contamination occurring in your storm sewer system. The dye is that is employed is biodegradable, so it causes no harm to wildlife, your water infrastructure, or waterways.
Inclination Reporting
Inclination reporting, aka slope or grade, is an important data set for any wastewater system, especially if the sewers are new installations. An inclination report will include information on pipe alignment, sag, and any other irregularities that could impact the efficiency and safety of your sewer system. Knowing this information is vital to maintaining industry standards and meeting design and regulatory requirements.

Planning & Design
GPRS is a utility locating company that provides you with accurate existing conditions documentation to streamline planning & design. We give you the tools to Intelligently Visualize The Built World® – including maps, drawings, and even 3D models of your subsurface infrastructure to help you plan and execute better.
Construction
Prior to trenching, directional drilling, demolition, and other excavation work during the construction or renovation of your site or facility, it is critical to accurately map and measure all of your above and below-ground infrastructure and assets to develop plans for safe crossing.
When deploying directional drilling and trenchless technologies, it is vital to know how to install lines safely, and also to “check your work” after installation to ensure any cross bores are identified and repaired.
GPRS provides the accurate existing condition documentation and NASSCO-certified reporting you need to complete any excavation and installation project safely.
O&M/Remodel
Renovations, changes & new excavations are a fact of life. GPRS helps you focus your plans with 2-4mm accurate CAD drawings & 3D BIM models that can integrate all of your infrastructure as-builts, and provide you with accurate floor plans via FLRLN, so you can target your workflow safely and efficiently.
///THE RIGHT TOOLS
Mainline Crawler
All GPRS Project Managers are experts in utilizing CCTV cameras to investigate sanitary and storm sewers as part of our Video Pipe Inspection Services. Mainline crawlers and their small-diameter crawler cousins are used in concert with push cameras, EM locators, and other technology to provide accurate, comprehensive subsurface visualization and NASSCO-certified reporting.
.webp)
EM Locator
Electromagnetic (EM) locators are the tools preferred by One Call contractors to locate public utility lines. GPRS utilizes EM devices in concert with GPR and our VPI technologies as part of our Subsurface Investigation Methodology (SIM) process to passively detect live AC power or radio signals that travel along conductive utilities. It can also be used to find accessible metallic pipes, risers, or tracer wires.
Lateral Launch
GPRS uses lateral launch cameras as part of a video pipe (CCTV) inspection and/or a full-site utility locate to non-destructively investigate lateral storm and sanitary sewer lines upstream of a mainline to find pipe defects, cross bores, abandoned pipes, and effectively map a sewer system.
Push Camera
Push cameras, also called flexible rodders, can access pipes through smaller spaces than crawlers, like vents, cleanouts, and toilet plumbing to locate small lateral lines in a sewer system. The push camera contains a sonde that can also be detected by a properly programmed EM locator to map non-metallic pipes as part of a full site utility scan or NASSCO VPI report.
