Using CCTV Drainage Inspections to Identify Sources of Odours

Benefits of Using CCTV for Odour Detection

• Provides a clear visual inspection of the entire drainage system
• Can identify issues that are not visible from the surface
• Allows for precise location of odour sources
• Non-invasive method that doesn't require excavation

Common Odour Sources Detectable by CCTV

• Cracked or Broken Pipes: Damage to pipes can allow sewer gases to escape, causing odours. CCTV can reveal cracks, fractures, or breaks in the pipework.
• Blocked Drains: Accumulations of debris, grease, or other materials can lead to blockages that cause odours. CCTV cameras can spot these obstructions.
• Root Intrusion: Tree roots growing into pipes can cause blockages and allow sewer gases to escape. CCTV inspections can clearly show root infiltration.
• Dry P-Traps: P-traps that have dried out allow sewer gases to enter buildings. While CCTV can't directly see this, it can identify issues that may be causing P-traps to dry out.
• Pipe Misalignments: Poorly aligned pipes can trap waste and lead to odours. CCTV surveys can detect these alignment issues.
• Collapsed Sections: Collapsed portions of pipe can cause major blockages and odour problems. CCTV easily identifies these collapsed areas.

CCTV Inspection Process

• A high-resolution camera is inserted into the drainage system
• The camera is guided through the pipes, transmitting real-time video
• Technicians analyse the footage to identify potential odour sources
• Problem areas are mapped and documented for further action

Follow-up Actions

• Pipe repairs or replacements
• Targeted drain cleaning
• Root removal
• Realignment of misaligned pipes
