video pipe inspection services
NASCCO-certified inspection services with cross bore detection
GPRS provides NASSCO-certified video pipe inspection services and main line sewer scope inspections with PACP, LACP, and MACP-certified Project Managers to assess pipe conditions, document defects, and map sewer infrastructure. Detailed WinCan VPI reports are securely delivered through our SiteMap® GIS platform for easy access and seamless team coordination.
Understanding the condition, location, and flow direction of your storm and sanitary sewer infrastructure helps your team avoid rework, delays, safety risks, and costly emergencies. Video pipe inspection turns buried unknowns into actionable data, helping you identify illicit tie-ins, detect cross bores, uncover pipe defects, and mitigate contamination risks before they become problems.
Your Sewer System, Fully Visualized.
See every sewer line, defect, and flow direction in one GIS platform, with complete water and sewer system mapping.
Video pipe inspection (VPI), also known as CCTV sewer inspection or sewer scoping, utilizes CCTV cameras mounted on robotic crawlers or lateral launch cameras, to inspect the interior of sanitary sewers, storm sewers, sewer laterals, manholes, and mainline systems without excavation. The camera transmits live footage that a GPRS Project Manager reviews to document pipe defects, assess structural condition, and identify cross bores, cracks, root intrusion, and offset joints. GPRS delivers VPI findings and maps via their SiteMap GIS infrastructure platform. A GPRS VPI report includes an interactive WinCan report, with all pipe segments and defects mapped, PACP-coded, and catalogued by severity.

///pricing for vpi services
Residential sewer inspections typically range from $250–$1,200, and inspection equipment can cost $75,000–$100,000, but GPRS’ NASSCO-certified video pipe inspection is priced per project. Costs vary based on scope, site complexity, and the areas being inspected, including linear feet, pipes, laterals, cleanouts, and manholes. GPRS provides customized quotes based on your specific project requirements.
Visualize your sewer infrastructure with GPRS’ SiteMap Sewer Layer, combining video pipe inspection data, GIS mapping, and real‑time access to pipe conditions, flow direction, and defects.
Review accurately mapped storm and sanitary sewer assets, evaluate pipe conditions, confirm flow direction, depths, and locations, and securely share information with decision-makers and team members from a single source of truth.
Access your WinCan Web photo and video reports and your NASSCO PACP, LACP, and MACP-coded defect reports, so you can easily access, report, and share information, plan repairs, and maintain your sewer lines without excessive potholing.

NASSCO is the National Association of Sewer Service Companies. NASCO sets industry standards for assessing, maintaining, and rehabilitating underground water and sewer infrastructure. All GPRS Project Managers are NASSCO trained and certified, and provide NASSCO Video Pipe Inspection Reports via WinCan for our customers, delivered via SiteMap for secure, accessible documentation that’s available 24/7.
GPRS VPI Project Managers are experts in NASSCO inspection and classification standards. Every VPI deliverable is coded and graded to NASSCO PACP (Pipeline Assessment Certification Program), MACP (Manhole Assessment Certification Program), or LACP (Lateral Assessment Certification Program) standards, the format accepted by municipalities, engineers, and public works departments nationwide. PACP grades mainline pipe defects. MACP grades manhole structure. LACP covers lateral service lines. GPRS delivers the applicable report for every inspection performed.

///FREQUENTLY ASKED QUESTIONs
Video pipe inspection (VPI) is the use of a CCTV camera, mounted on a robotic crawler or lateral launch system, to inspect the interior condition of sewer, storm drain, and process piping without excavation. The camera travels the full length of the pipe, transmitting live footage that a NASSCO-trained technician reviews to document defects, assess pipe condition, and identify cross bores, cracks, root intrusion, offset joints, and structural damage. GPRS delivers our findings and digital sewer maps via SiteMap. They include a comprehensive digital sewer map, and a WinCan interactive report with every defect coded, graded, and located.
A GPRS Project Manager inserts a robotic crawler or lateral launch camera at an access point, typically a manhole or cleanout. The camera travels the pipe while transmitting live video footage. The VPI Project Manager catalogues, codes, and grades every defect observed using PACP, MACP, or LACP standards. Findings are compiled into a WinCan interactive report and a digital sewer map and delivered via SiteMap.
Every GPRS VPI report includes a WinCan interactive report
- Each defect coded and graded to NASSCO PACP, MACP, or LACP standards
- Defect locations referenced to the nearest surface feature
- Full-length video of the pipe interior
- Photo documentation at each defect location
- A PDF summary report with repair prioritization by defect severity
- A comprehensive digital sewer map and access to all inspection data 24/7 via SiteMap

NASSCO (National Association of Sewer Service Companies) developed the Pipeline Assessment Certification Program (PACP) - the standardized coding and grading system for sewer pipe defects used by municipalities, engineers, facility managers, and public works departments nationwide. GPRS VPI Project Managers are NASSCO-trained and all VPI deliverables are coded and graded to NASSCO PACP standards, making reports compatible with municipal procurement requirements and asset management systems.

The PACP (Pipeline Assessment Certification Program) is the grading system for defects in sewer mainlines. The MACP (Manhole Assessment Certification Program) covers structural defects in manholes. The LACP (Lateral Assessment Certification Program) applies to lateral (service) lines. GPRS delivers full VPI reports coded to the appropriate standard required for the infrastructure inspected.
GPRS inspects sanitary sewer mains and laterals, storm drain and stormwater systems, potable water mains, industrial and process drain lines, campus and facility sewer networks, large-diameter transmission mains, and post-HDD pipelines for cross bore detection.
Recurring drain backups or slow drainage throughout a building, unexplained wet spots or ground settlement near known sewer lines, foul odors inside or around the building, any horizontal directional drilling near existing sewer lines requiring cross bore detection, pre-commissioning baseline inspection for new construction, or scheduled O&M inspection as part of a sewer asset management program.
Sewer cleaning, utilizing services like jetting or hydro excavation, removes debris, root intrusion, grease, and blockages from inside the pipe, but it does not assess condition. Sewer inspections use CCTV cameras to document pipe interiors and grade defects per NASSCO standards. Inspection is typically performed before cleaning to establish a baseline, and after cleaning to confirm results. GPRS provides comprehensive video pipe inspection services, and can help you subcontract cleaning is performed by a separate contractor if needed.
GPRS delivers WinCan reports coded to NASSCO PACP, MACP, and LACP standards – the format accepted by municipalities, public works departments, and engineering firms nationwide. Reports include defect coding, condition grading, location referencing to surface features, and full HD video documentation. Plus, GPRS goes a step beyond by providing a comprehensive digital sewer map that shows customers the exact location, flow direction, and depth of their sewer systems.

Yes. GPRS offers full pre and post-cross bore inspections. After a horizontal directional drilling installation and before sewer cleaning operations begin, GPRS inspects the existing sewer and drain lines at all crossing points to detect and document any intersections between the new utility and existing pipes. This prevents the potentially fatal pipe rupture that can occur when a gas line cross bore is struck during high-pressure sewer jetting.

SiteMap Sewer Layer includes geolocated sewer inspection data that helps customers visualize pipe segments, laterals, and related wastewater assets together with their PACP, LACP, and MACP condition information. Depending on the inspection scope, that can include flow direction, pipe depth, pipe material, entry and exit points, all discovered pipe defects, cross bores, NASSCO-coded condition data, photos, and in-app video for each inspected segment.
We build our VPI deliverables from CCTV inspection and locating data, and provide it as a secure, shareable digital record your team can use for maintenance planning, operations and maintenance, and capital decision-making.
