CCTV Pipeline Condition Assessment

Data-driven clarity for confident decision-making

Pipeline condition assessments guide maintenance plans, reveal hidden risks and support capital works decisions. With industry-leading technology, InterGroup delivers actionable insights and high-quality visual evidence to asset owners and engineers.

InterGroup operates New Zealand’s largest and most advanced fleet of CCTV pipeline inspection equipment, supporting councils, utilities, and infrastructure owners with high-accuracy condition assessment of stormwater and wastewater networks.

Our service is delivered by highly trained field technicians and a centralised team of certified coders. All inspection coding is independently audited and consistently achieves 95–100% accuracy, providing reliable, decision-ready asset data for maintenance planning and capital investment.

We provide CCTV pipeline inspection and condition assessment across water, stormwater, and wastewater networks using HD crawler CCTV systems, laser profiling, pole cameras, and confined space inspection drones with LiDAR capability. This allows safe, efficient identification of defects in complex or high-risk infrastructure without unnecessary excavation or service disruption.

What our CCTV inspections identify

Our pipeline condition assessments support early detection of:

  • Structural defects, cracks, fractures, and pipe collapse risk
  • Infiltration and leakage in stormwater and wastewater systems
  • Blockages, sediment build-up, and flow restriction issues
  • Tree root intrusion and joint displacement
  • Incorrect connections and installation defects

These insights support accurate engineering decisions and targeted maintenance strategies.

What our inspections deliver

  • High-accuracy CCTV reporting (95–100%) for confident asset decisions
  • Structured defect coding aligned to industry standards
  • GIS-ready asset data for infrastructure management systems
  • Pre-repair verification and post-rehabilitation validation
  • Reduced need for unnecessary excavation and network disruption

Proven in critical infrastructure programmes

Our capability is trusted for large-scale, high-risk asset networks, including:
