Top 10 Questions for Sewer Cleaner Interview

1. What are the different types of sewer cleaning equipment and their uses?

There are various types of sewer cleaning equipment, each designed for specific tasks and conditions. Some common types include:

• Drain snakes: Flexible cables with a variety of attachments, such as augers and blades, for unclogging pipes.
• Hydro jetters: High-pressure water jets that clear blockages and remove debris.
• Vacuum trucks: Equipped with powerful vacuum pumps to remove liquid waste and debris from sewers.
• Sewer cameras: Cameras mounted on flexible cables to inspect sewer lines for damage and blockages.
• Trenchless pipe bursting: A method of replacing damaged sewer lines without excavation, using a bursting head to break the old pipe and pull a new one into place.

2. How do you determine the cause and location of a sewer blockage?

Identifying the Cause

• Collect information from the customer about the nature of the blockage (e.g., symptoms, frequency).
• Conduct visual inspections of the sewer system, including manholes and cleanouts, to check for obvious blockages.
• Use specialized equipment, such as sewer cameras, to inspect the sewer lines and pinpoint the source of the problem.

Determining the Location

• Measure the distance from a known reference point (e.g., manhole) to the blocked area using a drain snake or sewer camera.
• Use electronic locators to detect the position of buried sewer lines and pinpoint the blockage.
