What common tools are primarily used for sewer line inspection?

CCTV cameras and sonar devices are specifically designed for sewer line inspection, making them the primary tools used in this area.

CCTV cameras allow for real-time video footage of the inside of sewer pipes, enabling inspectors to identify blockages, cracks, and other structural issues efficiently without needing to excavate. This non-invasive approach is critical for reducing costs and minimizing disruption.

Sonar devices are utilized to assess the condition of the sewer lines by sending sound waves to detect obstructions and measure distances within the pipes, particularly in scenarios where visibility is compromised, such as in deeper or murky water.

Together, these tools provide comprehensive data to sewer maintenance professionals, ensuring effective assessment and maintenance of sewer systems.
