CCTV drain surveys, also known as closed-circuit television drain surveys, are inspections of drainage systems using specialised cameras. These surveys involve the use of CCTV cameras to capture real-time footage and images of the inside of drains, pipes, and sewers. The cameras are mounted on a flexible rod that can be inserted into the drainage system to provide a comprehensive visual assessment.
Inspection Process: A professional drainage engineer or technician will use CCTV cameras specifically designed for drain surveys. The cameras are waterproof and can navigate through the drain system easily.
Camera Insertion: The CCTV camera is attached to a flexible rod or cable, which is then inserted into the drain or sewer. The rod can be manually pushed or controlled remotely to navigate through the pipes.
Live Feed and Recording: The camera captures real-time footage of the interior of the drains as it moves along. The footage is displayed on a monitor, allowing the technician to assess the condition of the drains, identify any blockages, leaks, or structural issues, and locate specific problem areas.
Documentation and Reporting: The CCTV drain survey provides detailed visual evidence of the condition of the drains. The technician will document any findings, including the location and extent of any issues, and create a report or survey summary for the client.
Problem Identification: The survey helps identify various drain-related issues, such as blockages caused by debris, tree roots intrusion, collapsed pipes, cracks, leaks, or inadequate installation. By pinpointing the problems accurately, the appropriate solutions can be recommended.
CCTV drain surveys offer several benefits:
Accuracy: The real-time video footage provides a clear and accurate view of the condition of the drainage system, allowing for precise identification of issues.
Cost and Time Efficiency: CCTV drain surveys help locate problems quickly, eliminating the need for unnecessary digging or exploratory works. This saves time and reduces the cost of repairs or maintenance.
Preventive Maintenance: Regular CCTV drain surveys can identify potential issues before they become major problems, allowing for proactive maintenance and minimising the risk of expensive repairs in the future.
CCTV drain surveys are typically carried out by specialised drainage companies or professionals with expertise in drain inspection. If you suspect issues with your drainage system or need a comprehensive assessment, contacting a reputable drainage company in your area is recommended.
