What is a CCTV Drain Survey?


A CCTV drain survey is a non-intrusive method of inspecting drains using high-resolution cameras. These state-of-the-art cameras are mounted on remote-controlled equipment, allowing drainage experts to explore the entire drainage system with ease. By capturing real-time footage, CCTV drain surveys enable professionals to identify blockages, leaks, structural damage, root ingress, and other issues that may be affecting the functionality of the drains.


The Process


A typical CCTV drain survey involves the following steps


Initial Assessment

Before the survey commences, a thorough assessment of the drainage system is conducted. This includes examining the access points and determining the best strategy to navigate through the drains.


Camera Insertion

Once the assessment is complete, a high-resolution camera is attached to a flexible rod or cable. The camera is then inserted into the drain through an access point, such as a manhole or an inspection chamber.


Remote Inspection

As the camera travels through the drainage system, it captures detailed footage of the interior. This footage is transmitted to a monitor in real-time, allowing the drainage experts to examine the condition of the drains thoroughly.


Identification of Issues

The professionals carefully analyse the footage to identify any issues that may be present within the drainage system. These can include blockages caused by debris, tree roots invading the pipes, cracks or fractures, collapsed sections, or other structural abnormalities.


Reporting and Recommendations

Based on the findings, a comprehensive report is generated. The report outlines the condition of the drains, highlights any problem areas, and provides recommendations for necessary repairs or maintenance work.


Clearing and Protecting Drains


CCTV drain surveys play a vital role in clearing and protecting drains by offering several benefits:


Accurate Diagnosis

With high-definition footage and real-time monitoring, CCTV drain surveys provide accurate and detailed information about the condition of drains. This enables professionals to pinpoint the exact cause of issues, facilitating effective and targeted solutions.


Preventative Maintenance

By identifying potential problems before they escalate, CCTV drain surveys allow for proactive maintenance. This helps in preventing major drainage issues, reducing the risk of costly repairs and minimising disruption to daily operations.


Efficient Clearing

In cases where blockages are identified, CCTV drain surveys aid in devising the most appropriate and efficient clearance methods. This ensures that blockages are cleared effectively, without causing further damage to the drainage system.


Protection of Buildings


CCTV drain surveys not only safeguard the drains but also protect domestic and commercial buildings in various ways:


Structural Integrity

By detecting any damage or structural issues within the drains, CCTV surveys help prevent potential risks to the building's structural integrity. Identifying and repairing these problems early on can prevent further damage, such as subsidence or foundation issues.


Water Damage Prevention

Blocked or damaged drains can lead to water leaks or sewage backups, resulting in significant damage to the building's interiors and foundations. CCTV drain surveys allow for the timely detection of such issues, enabling prompt repairs and preventing water-related damage.


Health and Hygiene

Blocked or damaged drains can harbour harmful bacteria and pests, posing health risks to occupants. CCTV drain surveys aid in identifying and eliminating these problems, ensuring a clean and hygienic environment within the building.



CCTV drain surveys are a powerful tool in maintaining the functionality and integrity of drains, as well as protecting both residential and commercial buildings.
