Protect your underground assets with advanced CCTV pipeline inspection technology. TDG Environmental delivers comprehensive condition assessments that identify problems before they become costly emergencies, ensuring your drainage and sewer networks operate efficiently and compliantly across New Zealand's North Island.
Underground pipeline failures create significant operational and environmental risks. Without regular inspection, issues remain hidden until they cause system failures, environmental contamination, or costly emergency repairs.
Structural Deterioration
Cracks, fractures, and pipe collapse threaten system integrity and can lead to expensive excavation and replacement work.
Blockages and Obstructions
Tree root intrusion, debris buildup, and sediment accumulation reduce flow capacity and cause backups that impact operations.
Joint Failures and Misalignment
Separated joints and displaced pipes create infiltration points and exfiltration risks that compromise system performance.
Corrosion and Material Breakdown
Chemical attack and age-related degradation weaken pipes, leading to leaks, contamination, and structural failure.
Compliance and Liability Risks
Undetected defects create liability under the Resource Management Act 1991 and Health and Safety at Work Act 2015, exposing organisations to significant financial and legal consequences.
TDG Environmental employs advanced CCTV inspection technology to provide detailed, accurate assessments of your underground pipeline networks.
Our fleet of remotely operated CCTV robots features silent inverter technology, allowing inspections in noise-sensitive environments. These sophisticated systems navigate pipelines from 150mm to 3,000mm diameter, capturing high-definition video and data whilst minimising disruption to your operations.
Every pipeline inspection follows the New Zealand Pipe Inspection Manual (NZPIM) standards, ensuring consistent, reliable reporting. Our certified operators identify and code defects according to recognised classification systems, providing you with actionable data for maintenance planning and capital works programming.
For complex assessment requirements, we deploy multi-sensor inspection (MSI) profiling that combines HD panoramic cameras, sonar, and infrared laser technology. This approach delivers comprehensive 360-degree pipe profiles, accurately measuring ovality, corrosion, capacity, and debris volume in challenging conditions including high-flow environments.
All inspection data uploads instantly to our cloud-based UtilityTrack platform, providing immediate access to survey results, video footage, and condition reports. This GIS-integrated system allows you to view, analyse, and export data from any device, supporting informed decision-making and efficient asset management.
Push Camera Systems inspect inspect narrow pipelines and service laterals under 150mm diameter, identifying defects in difficult-to-access locations.
Boat Survey Technology assesses large-diameter pipes with high water levels and fast flow conditions, eliminating the need for costly dewatering or confined space entry.
CleverScan Manhole Inspection captures detailed manhole imagery without confined space entry, streamlining safety procedures whilst maintaining inspection quality.
Following inspection, you receive detailed condition assessment reports highlighting structural and serviceability issues, recommended remediation actions, and estimated repair costs. Our team provides rehabilitation recommendations for identified defects, supporting strategic asset management and budget planning.
Proven Industry Expertise
With over 30 years of environmental services experience, TDG Environmental brings proven systems and technical capability to every North Island project. Our team understands the unique challenges of New Zealand’s infrastructure environment and regulatory landscape.
Advanced Technology Fleet
We invest continuously in cutting-edge CCTV inspection technology, including silent inverter robotics, multi-sensor profiling systems, laser measurement tools, and specialised survey equipment. This comprehensive capability ensures we can inspect any pipeline configuration regardless of size, material, or condition.
Qualified and Certified Operators
Our CCTV operators hold relevant certifications and undergo regular training in inspection standards, safety procedures, and equipment operation. This expertise ensures accurate defect identification, proper condition coding, and reliable reporting that meets regulatory requirements.
Instant Data Access Through UtilityTrack
Unlike traditional inspection services that delay data delivery, our UtilityTrack platform provides immediate access to inspection results. Video streams, condition reports, and GIS data are available as soon as surveys complete, supporting rapid response to critical findings and efficient project management.
Regulatory Compliance Assurance
We understand New Zealand’s regulatory framework including the Resource Management Act 1991, Health and Safety at Work Act 2015, and regional council requirements. Our inspection processes and reporting align with these obligations, helping you maintain compliance and manage environmental responsibilities.
Inspection frequency depends on pipe age, material, and operating conditions. Critical infrastructure typically requires assessment every 3-5 years, whilst older systems or those with known issues benefit from annual inspection. We can develop a risk-based inspection schedule tailored to your network and regulatory obligations.
Our CCTV equipment inspects pipelines from 150mm to 3,000mm diameter. For pipes under 150mm, we use specialised push camera systems. For larger pipes with high water levels, we deploy boat survey technology. This comprehensive capability covers virtually all drainage and sewer pipeline configurations.
We use specialised CCTV boats and multi-sensor inspection systems designed for high-flow conditions. These technologies eliminate the need for costly dewatering whilst delivering accurate condition assessment. For extreme conditions, we can coordinate with your operations team to optimise flow management during inspection.
Reports comply with NZPIM standards and can be delivered in multiple formats including PDF, Excel, or direct GIS data export. UtilityTrack provides instant online access to all inspection data, video footage, and reports. We can customise reporting formats to integrate with your asset management systems.
Yes, our CCTV robots access pipelines through standard manholes and access points regardless of surface conditions above. This non-destructive approach eliminates excavation requirements, making it ideal for inspecting pipes beneath buildings, roads, or other sensitive infrastructure.
We offer 24/7 emergency CCTV inspection services across the North Island. Our rapid response capability helps identify failure causes, assess damage extent, and support emergency repair planning during critical incidents.
Our reports include detailed defect descriptions, condition gradings, and rehabilitation recommendations. We can provide cost estimates for repairs and integrate CCTV findings with our pipeline cleaning, robotic cutting, and trenchless rehabilitation services to deliver complete remediation solutions.
Yes, we use CleverScan technology to inspect manholes without confined space entry, capturing detailed imagery of manhole walls and identifying structural defects and infiltration issues. This approach improves safety whilst reducing inspection costs and timeframes.
All inspection data stores securely on our UtilityTrack cloud platform with redundant backup systems. Authorised users access data instantly from any internet-connected device. Data remains available throughout your contract period and can be exported in standard GIS and database formats.
Yes, UtilityTrack supports data export in ESRI Shapefile, MapInfo TAB, AutoCAD DXF, and standard database formats. We can configure customised data exports and API integrations to ensure seamless compatibility with your asset management and GIS systems.
