During a drain survey, state-of-the-art camera technology is pushed or driven along the pipe whilst the drainage engineer monitors the screen, this allows the drain engineer to take a closer look at the inside of drains, pipes and sewers. These surveys identify the cause and nature of blockages.

In conjunction with the CCTV Camera is our sonar drain tracing and mapping equipment. This allows us to pinpoint from above the ground the exact location of objects such as:
