A cctv drain survey is one of the most effective and non-invasive ways to assess the condition of a drainage system. Whether you’re dealing with persistent blockages, planning property works, or investigating structural issues, a survey provides clear and accurate footage that helps diagnose problems quickly.
At London Drainage Services, we’ve spent more than 20 years carrying out professional cctv surveying across London and the Home Counties. Our aim is always simple: deliver fast, efficient, and economical solutions with minimal disruption to your home or business.
To ensure your survey runs smoothly, a little preparation goes a long way. Below, we explain exactly what clients need to do before their appointment and why each step matters.
Why Preparing for a CCTV Drain Survey Is Important
A cctv drain survey uses advanced camera equipment to travel through your drainage system, capturing live footage and identifying issues such as cracks, root intrusion, blockages, collapsed pipes, scale build-up, and structural defects.
Preparing correctly ensures the camera can move freely, access points are safe, and the survey technicians have all the space and information they need to carry out a detailed inspection. Good preparation means more accurate results and a quicker diagnosis helping you get your drainage system back to full working order efficiently.
1. Clear All Access Points
Before the survey begins, make sure that manholes, inspection chambers, and other access points are free from blockage and easy to reach. Remove any debris, vegetation, obstacles, or stored items that may prevent engineers from lifting covers or safely accessing the drains.
This step ensures the team can set up quickly and reduces delays on arrival. It also helps prevent accidental damage to surrounding surfaces and ensures safe working conditions.
2. Unblock Drains If Necessary
A cctv drain survey works best when the pipes are clear. If the drains are currently blocked, or if water is standing in the system, the camera may not be able to travel through the pipes freely. This can prevent accurate footage and hide underlying issues.
Where necessary, unblock the drain before the survey or speak to the survey provider such as LDS who can clear the blockage on site as part of the overall service. Ensuring clean pipework allows the camera to capture clear, uninterrupted footage.
3. Communicate Known Issues Beforehand
When booking your survey, always explain any recurring problems or specific areas of concern. Whether you’ve noticed slow drainage, gurgling sounds, foul smells, or repeated blockages, sharing this information helps focus the inspection on the right areas.
The more detail you provide, the more tailored and efficient the survey will be. Clear communication also ensures the engineers bring the appropriate equipment and plan the right access route.
4. Make Space for Equipment Setup
CCTV survey equipment can include cameras mounted on flexible rods or advanced robotic crawler systems, depending on the size and complexity of the drainage network.
To prepare, ensure there is enough clear space around access points for the team to set up their equipment safely. This might mean clearing pathways, moving bins, or shifting vehicles to provide easy access.
A clear workspace enables the engineers to work efficiently and ensures the equipment remains clean, stable, and protected.
5. Schedule the Survey at a Suitable Time
Where possible, choose a time when weather conditions or onsite activity won’t interfere with the survey. Heavy rain can affect the visibility inside pipes, and construction works nearby may obstruct access points.
Selecting the right time helps ensure an accurate survey and reduces the likelihood of needing to repeat any part of the inspection.
6. Ensure All Required Permissions Are in Place
If the survey involves access points on shared land, public spaces, or neighbouring property, make sure permission has been granted before the appointment.
This avoids delays, prevents legal complications, and ensures the team can carry out the approach safely and professionally. Keeping the area free from hazards also helps ensure technician safety throughout the survey process.
What Happens During the Survey?
Once preparation is complete, your LDS engineer will lower the camera carefully into the drainage system and begin recording real-time footage as it travels through each pipe. The camera sends live images to a monitor, allowing the engineer to assess the condition instantly.
Afterwards, you’ll receive a detailed written report, footage (if requested), and recommendations for repairs, maintenance, or further investigation. Our engineers always explain the findings clearly, giving you complete confidence and peace of mind.
