CCTV Drain Inspection
Detailed camera surveys of drainage and sewer pipelines to identify blockages, structural defects, and maintenance needs without excavation.
Overview
CCTV drain inspection allows us to see exactly what's happening inside your pipelines. By inserting a high-resolution camera into the drainage system, we can identify blockages, cracks, root intrusions, joint displacements, corrosion, and structural damage — all without any excavation or disruption.
Our CCTV surveys provide clear, recorded footage with distance markers and annotations, giving property managers and building owners a full picture of their pipeline condition. This data is essential for planning maintenance, prioritising repairs, and verifying the results of clearing or rehabilitation work.
SPS Jetting's inspection team uses professional push-camera and crawler systems suited for pipes ranging from small internal drains to large trunk sewers.

CCTV Drain Inspection — Frequently Asked Questions
Common questions about cctv drain inspection in Singapore, answered by our plumbing and drainage specialists.
What is CCTV drain inspection?
CCTV drain inspection is a non-destructive method of assessing the internal condition of drainage pipelines using specialised waterproof cameras. The camera is inserted into the drainage system and transmits live video footage, allowing technicians to identify defects, blockages and structural issues without the need for unnecessary excavation.
This technology is widely used in residential, commercial and industrial properties throughout Singapore to investigate recurring drainage problems, verify pipe conditions and support maintenance planning. Depending on the pipe size and site conditions, inspections may be carried out using push cameras for smaller pipelines or robotic crawler cameras for larger underground drainage systems.
A CCTV drain inspection provides valuable information about the condition of the pipeline, enabling property owners and facility managers to make informed decisions before carrying out repairs or maintenance.
CCTV inspection is not just for blocked drains. Many organisations use it as a preventive maintenance tool to identify developing issues before they become major failures.
When should you engage a professional?
If you are experiencing recurring drain blockages, unexplained foul odours, slow drainage or suspect hidden pipe damage, a CCTV drain inspection can accurately identify the underlying cause without destructive investigation.
How does CCTV drain inspection work?
A CCTV drain inspection begins by identifying suitable access points, such as inspection chambers or manholes. A specialised waterproof camera is then introduced into the drainage pipeline and carefully guided through the system while transmitting live video to a monitoring unit.
As the inspection progresses, trained technicians assess the condition of the pipeline, looking for signs of blockages, cracks, root intrusion, displaced joints, corrosion, sediment build-up and other defects. Significant observations are recorded to help determine whether cleaning, repairs or further investigation is required.
Where necessary, the inspection may be performed before and after high-pressure water jetting to ensure the pipeline has been thoroughly cleaned and to confirm whether any structural defects remain.
A clean pipeline produces a much clearer inspection. For heavily contaminated drains, high-pressure water jetting is often recommended before CCTV inspection to improve visibility and inspection accuracy.
When should you engage a professional?
Professional CCTV inspection is recommended whenever the cause of a drainage issue is uncertain or when visual confirmation is required before making repair decisions.
What problems can CCTV drain inspection identify?
CCTV drain inspection can identify a wide range of drainage defects that are often impossible to detect from the surface.
Common issues include:
- Pipe cracks and fractures.
- Root intrusion.
- Displaced or open pipe joints.
- Pipe deformation.
- Partial or complete pipe collapse.
- Grease accumulation.
- Sludge and sediment build-up.
- Foreign object obstructions.
- Mineral scale deposits.
- Corrosion in ageing pipelines.
- Water ponding caused by incorrect pipe gradients.
- Construction debris or concrete obstruction.
By accurately locating these problems, CCTV inspection allows maintenance and repair work to be targeted only where necessary, reducing unnecessary excavation and minimising disruption.
Many recurring drain blockages are symptoms rather than the actual problem. CCTV inspection helps determine whether the issue is caused by build-up inside the pipe or by an underlying structural defect.
When should you engage a professional?
If the same drain continues to block despite repeated cleaning, a CCTV inspection can determine whether the issue is operational or structural.
When is CCTV drain inspection recommended?
CCTV drain inspection is recommended whenever the condition of a drainage pipeline cannot be confirmed through external observation alone. It is commonly used before major repair works, after recurring drainage failures and as part of preventive maintenance programmes.
Typical situations include:
- Recurring drain blockages.
- Slow-draining systems.
- Persistent foul odours.
- Suspected underground pipe damage.
- Flooding or overflowing inspection chambers.
- Pre-purchase property inspections.
- Insurance investigations.
- Verification after repair or rehabilitation works.
- Planned preventive maintenance for commercial and industrial facilities.
Rather than relying on assumptions, CCTV inspection provides visual evidence that supports accurate maintenance planning and informed decision-making.
Diagnosing a drainage issue without inspecting the inside of the pipeline can sometimes lead to unnecessary repairs. A CCTV inspection helps ensure that the proposed solution addresses the actual problem.
When should you engage a professional?
If your property has experienced repeated drainage issues or you require documented evidence of a pipeline's condition, CCTV inspection provides a reliable basis for further action.
Is CCTV drain inspection destructive?
No. CCTV drain inspection is considered a non-destructive investigation method because it uses existing access points to examine the drainage system without unnecessary hacking, excavation or damage to surrounding structures.
This makes it one of the safest and most efficient ways to investigate underground drainage problems while minimising disruption to property occupants and daily operations.
Only if the inspection identifies structural defects requiring repair would excavation or pipe rehabilitation be considered, and even then, the inspection helps limit the work to the affected section rather than replacing an entire pipeline unnecessarily.
For commercial properties, this approach can reduce downtime, lower investigation costs and support more accurate repair planning.
One of the greatest advantages of CCTV inspection is certainty. Instead of guessing where the problem may be, technicians can identify its exact location and condition before recommending the next step.
When should you engage a professional?
If you want to investigate drainage issues without damaging floors, roads or landscaped areas, CCTV drain inspection is usually the preferred first step.
Can CCTV drain inspection detect pipe leaks?
Yes. CCTV drain inspection can identify many visible signs associated with pipe leaks, including cracks, fractures, displaced joints, deteriorated pipe sections and areas where water appears to be entering or escaping the pipeline. While the camera itself does not measure water loss, it provides visual evidence of defects that are commonly responsible for leakage.
For underground drainage systems, CCTV inspection is one of the most effective methods for locating the source of recurring problems without unnecessary excavation. By identifying the exact location and severity of the defect, repairs can be targeted more accurately, reducing both disruption and repair costs.
In some situations, additional diagnostic methods may be recommended if the leak is suspected to originate from a pressurised water supply pipe rather than a gravity drainage system.
Not every leak is visible from the surface. Water may travel through soil before appearing elsewhere, making the visible wet area very different from the actual source of the problem. CCTV inspection helps narrow down the affected section before repairs begin.
When should you engage a professional?
If you notice unexplained wet areas, recurring drainage issues or suspect an underground drain leak, a CCTV inspection provides valuable information before any excavation is considered.
Can CCTV drain inspection identify cracked or collapsed pipes?
Yes. One of the primary purposes of CCTV drain inspection is to identify structural defects within drainage pipelines. During the inspection, technicians assess the internal condition of the pipe and record defects such as cracks, fractures, displaced joints, deformation and partial or complete pipe collapse.
The inspection also helps determine the severity and location of the damage. This information is essential when deciding whether the pipeline can be repaired, rehabilitated using trenchless methods such as CIPP lining, or requires replacement.
Rather than relying on assumptions, CCTV footage provides visual evidence that supports informed maintenance decisions and helps avoid unnecessary excavation or replacement of unaffected pipe sections.
Early-stage cracks are often much less expensive to address than pipes that have progressed to partial collapse. Routine inspections can identify defects before they become major failures.
When should you engage a professional?
If drains continue to block after cleaning, ground settlement is observed, or recurring repairs fail to resolve the issue, a CCTV inspection should be considered to assess the structural condition of the pipeline.
Can CCTV drain inspection detect tree root intrusion?
Yes. CCTV drain inspection is one of the most reliable methods for identifying tree roots that have entered drainage pipelines. The inspection allows technicians to determine where the roots have entered, the extent of the intrusion and whether the roots have caused damage to the pipe.
Tree roots commonly enter drains through small cracks, deteriorated joints or damaged sections of older pipelines. As the roots grow, they trap debris and restrict water flow, eventually leading to recurring blockages and possible structural damage.
Following the inspection, appropriate recommendations can be made. Depending on the severity of the intrusion, solutions may include high-pressure water jetting to remove fine roots, pipe rehabilitation, localised repairs or pipeline replacement where necessary.
Removing the roots alone does not always solve the problem. Unless the entry point is repaired, new roots may eventually grow back into the pipeline.
When should you engage a professional?
If the same drain blocks repeatedly, particularly near landscaped areas or mature trees, a CCTV inspection can confirm whether root intrusion is the underlying cause.
