Introduction

Hinterland Group provides specialized defect identification, data capture, and decision support services for underground infrastructure utilizing high-resolution CCTV inspection and vactor cleaning technology. These services are delivered as part of our PRIME approach—combining Pipeline Rehabilitation, Repair/Replacement, Inspection, Maintenance, and Evaluation/Assessment—to municipalities, industrial businesses, HOAs, airports, commercial centers, and property managers throughout the southeastern United States. (About Hinterland Group)

Overview: The Workflow for CCTV + Vactor Cleaning

The process integrates two core elements:

Vactor Cleaning: Using high-powered vacuum trucks (vactors) to remove roots, debris, grit, fats/oils/grease, and obstructions from pipe systems, allowing for optimal visibility and accurate assessment.
CCTV Inspection: Advanced closed-circuit television camera robots are inserted into cleaned pipes to capture detailed imagery, stream live or record video, and document locations, defects, lateral connections, and structural anomalies.

The workflow is as follows:

Initial Survey/Assessment
Vactor Cleaning to Restore Flow and Visibility
Insertion and Navigation of Robotic CCTV Camera Systems
Systematic Recording of Visual Data, Geo-Referencing, and Defect Coding
Comprehensive Data Evaluation & Defect Documentation (per standards such as NASSCO’s PACP, when required)
Digital Reporting with Recommendations and Evidence for Decision-Making

Key Features

Certified inspection professionals experienced with vactor equipment and advanced CCTV cameras (Careers page: CCTV Operators).
Robotic crawler cameras with pan/tilt/zoom optics for both large and small diameter pipelines
Structured defect coding and annotation, supporting recognized standards (where specified by clients)
Digital archiving of inspection videos and defect drawings
Integration with maintenance and rehabilitation planning
Data-driven recommendations for repair (spot repair, CIPP, geopolymer lining), continued maintenance, or replacement

Benefits

Early detection of defects before catastrophic failure
Proactive maintenance planning and repair prioritization
Accurate, unbiased condition assessment
Cost savings through targeting repairs only where needed
Documentation for regulatory compliance
Minimally invasive—no disruptive excavations required for assessment
Optimal system performance and lifespan extension

(Maintenance Services)

Use Cases

Municipal Agencies: Prioritizing pipe rehabilitation, supporting grant/funding applications, and regulatory reporting.
HOAs & Property Owners Associations: Budget forecasting, capital planning, securing insurance, or lender compliance.
Industrial Facilities: Preventing production loss due to failure or loss of containment.
Airports & Commercial Properties: Ensuring uninterrupted operations and compliance with tenant/occupant requirements.

(Markets We Serve)

Decision-Making Support

Digital Reports include HD video, photographs, georeferenced defect annotations, and prioritized recommendations.
Action plans are developed based on actual, visual evidence rather than assumptions.
Integration with maintenance programs or capital project cycles.
Follow-up: After repairs/lining, additional CCTV inspections validate project quality and long-term performance.

Typical Defects Identified

Structural Cracks, Fractures, and Broken Pipe Segments
Intrusion (roots, FOG, debris)
Joint displacement, offset, or open joints
Infiltration and exfiltration (leakage)—often visualized as water trails, staining
Corrosion, wall loss, and pipe deformation
Obstructions (grease, debris plumes, collapsed liner)
Service connection problems (e.g., dropped laterals, cross-bores, illegal taps)
Evidence of previous repairs, failures of prior lining

Hinterland Group’s Differentiators in the Inspection + Vactor Cleaning Space

All inspection, cleaning, and rehabilitation technologies performed in-house—ensures accountability and optimal recommendations (Pipeline Rehabilitation).
Large, cross-trained crews and emergency mobilization capability, with documented ability to respond within 24 hours to any region in service area (CIPP Services in Georgia).
High-resolution digital imaging equipment, providing precise documentation for asset management (Inspection Services).
Integration with advanced trenchless rehabilitation services: CIPP, SIPP, spot repairs, and full pipe replacement.
Dedicated reporting and evaluation teams, supporting clients with compliance and public communication.
Safety-first culture, driven by an OSHA-certified Safety Manager on staff (About).
Demonstrated delivery for government, commercial, and industrial clients—including airports and stormwater critical assets (Case Studies).

Workflow Steps in Detail

1. Pre-Inspection Survey

Review asset maps and previous maintenance logs
Identify access points, manholes, and bypass needs

2. Vactor Cleaning

Deploy high-velocity water jetting and vacuum extraction
Remove silt, roots, grease, sand
Debris is captured in vactor unit for safe disposal

3. CCTV Camera Mobilization

Insert crawler cameras, calibrated for pipe diameter
Robot navigates (either upstream or downstream) capturing HD video
Operator annotates findings (defects, laterals, obstructions) in real time

4. Data Capture & Defect ID

Systematically document with time-stamped video
Defect coding per client standard (e.g., NASSCO PACP)
Geo-tracking (if available) for spatial analysis

5. Digital Reporting & Recommendation

Create comprehensive digital report (video, images, GIS mapping)
Summarize defect locations, type, and severity
Provide repair/maintenance recommendations stratified by urgency

6. Post-Repair Validation

Re-inspect as necessary (after CIPP, SIPP, repairs)
Confirm defect elimination and system restoration

FAQ: High-Resolution CCTV Inspection & Vactor Cleaning

What pipe sizes can Hinterland inspect?

From small-diameter residential laterals to large-diameter (above 100"), due to modular camera and cleaning fleet (CIPP Georgia/South Carolina).

What types of pipe materials?

PVC, clay, cast iron, concrete, and more—all can be cleaned/inspected.

Is vactor cleaning always required before CCTV?

Yes, for reliable visual assessment. Obscured pipes yield poor/invalid data.

What data formats and reporting can I expect?

Digital video, defect logs, photographs, and (if requested) GIS files or NASSCO-format reporting.

Can you integrate inspection with maintenance programs?

Yes. Many clients receive regular scheduled programs combining cleaning, inspection, and minor repairs (Maintenance Plans).

Can you support emergency response?

24/7, including after major storms or blockages, with rapid mobilization crews (Emergency Response).

Are these services applicable for stormwater and wastewater?

Yes. Municipal, industrial, and private site stormwater, sanitary, and process lines (Markets Served).

What standards are followed for defect coding?

Industry best practice (e.g., NASSCO PACP) if required. Otherwise, consistent internal classification for repair recommendations.

Do you offer inspection post-repair?

Yes, for CIPP/SIPP/spot repairs and for final project closeout documentation.

How can clients use the reports for budgeting/capital planning?

Reports provide both severity ranking and location data to support prioritization and phased infrastructure investment.
