01 Quick Answer
A CCTV Camera Condition Inspection uses a high-resolution camera to visually inspect the inside of your drains and sewer pipes.
It helps identify defects such as:
-
Cracks
-
Blockages
-
Root penetration
-
Leaking joints
-
Structural damage
Providing you with a clear understanding of your drainage system's condition, helping you make informed decisions before costly problems develop.
02 What Is a CCTV Drain Survey
A CCTV drain survey (also known as a CCTV drain inspection or CCTV Camera Condition Inspection) is a non-invasive method of examining the internal condition of underground drainage pipes.
A small, high-resolution camera is inserted into your drainage system through an accessible opening such as a:
-
Manhole
-
Inspection chamber
-
Rodding point
The camera transmits live footage to an engineer on the surface, who records and assesses the condition of the pipework.
This provides an accurate, real-time view of your drainage system, allowing problems to be identified without the need for excavation or unnecessary disruption.

A CCTV Camera Condition Inspection is only valuable if the findings are presented clearly and professionally.
At Drainsmart, we provide straightforward reporting designed to help homeowners, buyers, architects, and commercial clients understand the condition of their drainage system and make informed decisions.
Depending on the type of inspection, your survey may include:
Written Report
A comprehensive report summarising the condition of the accessible drainage system, detailing any defects identified and providing clear recommendations where appropriate.
Still Photographs
High-quality images highlighting significant defects, changes in pipe condition and areas requiring attention.
CCTV Footage
A recording of the inspection allowing you, your surveyor, architect or insurer to review the condition of the drainage system.
Drainage Layout Drawing
An indicative computerised drainage layout showing the arrangement of the accessible drainage system and inspection chambers.
Defect Coding
Industry-recognised defect coding is used to classify observations consistently, making it easier for surveyors, insurers and other professionals to interpret the findings.
Recommendations
Where defects are identified, we'll explain their likely significance and provide practical recommendations. These may range from simple monitoring to cleaning, further investigation or repair work where necessary.
We believe in honest, evidence-based reporting. If your drainage system is in good condition, we'll tell you. If work is recommended, we'll explain why, without pressure or unnecessary repairs.
07 Different Types of CCTV Camera Condition Inspection
Every property and every client has different requirements, which is why we offer several CCTV Camera Condition Inspection packages tailored to different situations.
08 Why a CCTV Camera Alone Doesn't Always Tell the Whole Story
A CCTV Camera Condition Inspection provides an excellent assessment of the visible condition of your drainage system, but there are situations where a camera alone cannot identify every defect.
For example, pipework may appear structurally sound during a CCTV inspection while still leaking through defective joints that are not visibly open from inside the pipe.
These hidden leaks can allow wastewater to escape into the surrounding ground, potentially causing issues such as ground softening, damp or subsidence over time.
Where leakage is suspected, additional testing may be recommended.
Hydraulic Water Testing
Hydraulic Water Testing assesses whether sections of the drainage system remain watertight by monitoring water levels under controlled conditions.
This enables hidden leaks to be identified that may not be visible during a CCTV inspection alone.
It was this exact type of hidden defect that led us to introduce our Homebuyers Premium CCTV Camera Condition Inspection. During a previous inspection, the CCTV survey showed the drainage system to be structurally sound, but hydraulic testing later confirmed leakage through defective joints.
By combining CCTV inspection with hydraulic testing where appropriate, buyers can gain even greater confidence in the condition of the drainage system before completing their purchase.
09 What Happens if Problems Are Found?
Finding a drainage defect doesn't necessarily mean major repair work is required.
Some defects simply need monitoring, while others may benefit from routine maintenance or relatively minor repairs.
Our approach is always to provide honest advice based on the condition of the drainage system—not to recommend unnecessary work.
