CCTV Drain Surveys Across Scotland
Detailed CCTV drain surveys for commercial and infrastructure drainage systems. Using specialist push-rod and crawler camera equipment, we inspect pipework accurately, identify defects and provide clear footage with professional WinCan reporting. Our surveys support maintenance planning, repairs, property purchases, development projects and due diligence.
Clear Evidence Below Ground with CCTV Drain Surveys
CCTV drain surveys provide a clear and accurate assessment of underground drainage systems without unnecessary excavation.
Using specialist camera equipment, we record the internal condition of the pipework and identify defects, restrictions and areas requiring attention. This gives homeowners, businesses and project teams reliable evidence before maintenance, repair, development or property decisions are made.
Our findings are explained clearly, with practical recommendations based on the condition and performance of the drainage system.
Problems Our CCTV Surveys Identify
CCTV surveys allow us to inspect the internal condition of drainage pipework and identify problems that cannot be seen from the surface. This helps establish the cause, location and severity of an issue before repairs or maintenance are planned.
- Fractured, cracked or collapsed pipework
- Displaced, open or poorly sealed joints
- Root ingress
- Scale, grease, silt & debris deposits
- Sections of pipework holding water
- Poor gradients and displaced pipework
- Deformed or restricted pipes
- Obstructions causing repeated blockages
- Defective or poorly formed connections
- Previous repairs and patch liners
- Water infiltration and leakage
- Redundant or unconfirmed connection
CCTV Survey Equipment
Different drainage systems require different types of camera equipment. Our engineers select the most appropriate system based on the pipe diameter, access arrangements and scope of the investigation, ensuring clear footage and an accurate assessment of the drainage network.
Push-Rod Camera Systems-Our high-resolution push-rod camera systems are used to inspect smaller-diameter drains, internal waste connections and restricted drainage runs. They allow our engineers to identify blockages, fractures, displaced joints, root ingress, scale deposits and other defects. Where required, an integrated sonde can also be used to trace the drainage route and locate defects from ground level.
Crawler Camera Systems– For larger-diameter sewers and main drainage lines, powered crawler camera systems provide stable and controlled inspection over longer distances. The camera can rotate and zoom to examine connections and defects in detail, producing clear recorded footage and accurate survey information for condition assessment, maintenance planning and pre- or post-construction surveys.
Recording and Monitoring– All CCTV inspections are viewed live by our engineers and digitally recorded throughout the survey. Footage, still images and detailed observations can be compiled using WinCan software and MSCC5 coding, providing a clear record of the drainage condition and any identified defects. Our reports can also include recommended maintenance or remedial works where required.
Our CCTV Survey Process
- Review & Preparation– We review the survey requirements, available drainage information and accessible manholes or inspection points.
- Drainage Cleaning– Where necessary, the drainage is cleaned using high-pressure water jetting before the survey. This removes deposits and allows the pipe condition to be assessed properly.
- CCTV Inspection– The selected camera system is passed through the accessible drainage. Connections, defects and restrictions are recorded as the survey progresses.
- Reporting and Recommendations– The footage and survey observations are reviewed, with the findings presented alongside clear recommendations for cleaning, monitoring, repair or further investigation
WinCan Reporting & Survey Deliverables
Where formal reporting is required, CCTV survey findings can be documented using professional WinCan reporting software.
- Recorded CCTV survey footage
- WinCan survey report
- Drainage asset and section references
- Defect observations and coding
- Still photographs of significant defects
- Survey distances and locations
- Pipe sizes and materials where confirmed
- Access-point and manhole references
- Summary of survey findings
- Recommended remedial actions
- MSCC5 aligned defect coding where required
Residential CCTV Drain Surveys
Our residential CCTV surveys help homeowners, landlords, letting agents and property buyers understand the condition of underground drainage.
The survey may be recommended when investigating:
- Repeated or unexplained blockages
- Slow-flowing drains
- Suspected root ingress or damage
- Drainage beneath a proposed extension
- Problems following previous repairs
- Drainage condition before purchasing a property
- Suspected collapsed or displaced pipework
- Connections requiring confirmation
- Drainage before or after repair work
CCTV Drain Surveys for Home Buyers
Buying a property is a major investment, but the condition of the underground drainage is rarely covered in detail by a standard home survey.
Our home buyer CCTV drain surveys inspect the accessible drainage system before purchase, helping identify hidden problems that could lead to blockages, excavation or unexpected repair costs after completion.
The Survey can identify:
- Fractured or damaged pipework
- Displaced and open joints
- Root ingress
- Collapsed or restricted drains
- Scale, debris and grease deposits
- Sections of pipework holding water
- Poorly formed or defective connections
- Evidence of previous repairs
- Drainage affected by extensions or alterations
Clients can receive recorded footage, photographs and a clear report explaining the findings and recommended actions. This provides valuable evidence when considering the property, planning future work or discussing identified defects before completing the purchase.
Commercial, Development & Infrastructure CCTV Surveys
Envirotech supports facilities managers, developers, consultants, contractors and public-sector organisations with planned and investigative CCTV drainage surveys.
Our surveys can assist with:
- Drainage condition assessments
- Pre-construction surveys
- Post-construction surveys
- Development due diligence
- Planned maintenance programmes
- Repeated drainage failures
- Handover and completion inspections
- Pre-repair and post-repair evidence
- Large-diameter sewer inspections
- Investigations before excavation
- Drainage asset verification
- Supporting repair and rehabilitation design
Survey scopes can be tailored to suit individual infrastructure projects, development sites and extensive drainage networks. CCTV inspections can be used to establish asset condition, confirm connectivity, investigate defects and support maintenance, rehabilitation or construction planning across complex drainage systems.
All CCTV drainage surveys are completed in accordance with recognised UK industry standards for sewer inspection and condition classification, including the Manual of Sewer Condition Classification (MSCC) as referenced by the Water UK Standards Board. Survey findings are recorded consistently to provide clear, traceable information for clients, consultants, contractors and project teams.
When Should You Arrange a Drainage CCTV Survey?
A CCTV survey should be considered when:
- A drain blocks repeatedly after being cleared
- Structural damage or collapse is suspected
- The condition of existing drainage is unknown
- Work is planned above or close to underground drainage
- A property is being purchased or developed
- Drainage repairs or no-dig rehabilitation are being considered
- Evidence is required before and after construction
- A drainage system requires a planned condition assessment
- Connections or discharge routes cannot be confirmed visually
- A professional report is required for a consultant, contractor or client
Early investigation can prevent unnecessary excavation and allow repairs to be planned using accurate evidence.

Frequently Asked Questions
Does the drainage need to be cleaned before the CCTV survey?
The camera requires a reasonably clear view of the pipe surface. If silt, grease, scale or debris is restricting visibility, high-pressure water jetting may be required before the inspection.
What will I receive after the survey?
This depends on the agreed scope. Deliverables can include CCTV footage, photographs, a survey summary, WinCan reporting, defect observations and recommended remedial actions.
Can you survey both small and large drains?
Yes. We use different camera systems depending on the pipe diameter, access arrangements and survey requirements.
Can a CCTV survey identify the cause of repeated blockages?
A survey can identify structural defects, root ingress, scale, displaced joints, poor connections and other conditions that may contribute to repeated blockages.
Can you survey drainage before construction work?
Yes. Pre-construction surveys provide evidence of the drainage condition before work begins. A post-construction survey can then confirm whether the pipework has been affected.
Can you survey drainage beneath a property?
This may be possible where suitable access points are available and the camera equipment can negotiate the pipework.
What happens if the camera cannot pass through the drain?
The engineer will record the point where progress stops and explain the likely reason. Cleaning, alternative access or further investigation may then be recommended.
