Top 10 Questions for Sewer Connector Interview

1. Explain the process of connecting a sewer lateral to a main sewer line.

The process of connecting a sewer lateral to a main sewer line involves several steps:

• Excavating a trench to expose the main sewer line.
• Cutting the main sewer line and inserting a wye or saddle fitting.
• Connecting the lateral to the wye or saddle fitting using a rubber gasket or seal.
• Backfilling and compacting the trench.

2. What are the different types of sewer pipes used for connecting laterals to main lines?

PVC Pipes

• Lightweight and easy to install
• Resistant to corrosion and chemicals

Cast Iron Pipes

• Durable and long-lasting
• Heavy and require special equipment for installation

Vitrified Clay Pipes

• Resistant to corrosion and abrasion
• Brittle and can be damaged during installation

3. What are the common problems you encounter when connecting sewer laterals to main lines?

Common problems include:

• Misalignment of the lateral and main sewer line.
• Improper sealing of the connection, leading to leaks.
• Damage to the main sewer line during excavation or connection.
• Blockages in the lateral or main sewer line.

4. What safety precautions should you take when working with sewer lines?

Safety precautions include:

• Wearing appropriate personal protective equipment (PPE), such as gloves, safety glasses, and a hard hat.
• Ventilating the work area to prevent exposure to harmful gases.
• Using proper excavation and trenching techniques to prevent cave-ins.
• Following proper lifting techniques to prevent back injuries.

5. What tools and equipment are essential for sewer lateral connections?

Essential tools and equipment include:

• Shovels and picks for excavation.
• Saw or grinder for cutting pipes.
• Wrenches and pipe cutters for connecting pipes.
• Safety glasses, gloves, and hard hat.
• Trench shoring and bracing for safety.

6. How do you ensure the proper slope for a sewer lateral to prevent blockages?

To ensure proper slope, I use a level or transit to determine the elevation of the main sewer line and the lateral. I calculate the necessary slope, typically 1/4 inch per foot, and adjust the depth of the trench accordingly.

7. Explain the steps involved in inspecting a sewer lateral for defects or blockages.

• Remove any access covers or cleanouts.
• Insert a camera or inspection rod into the lateral.
• Illuminate the lateral and visually inspect for cracks, breaks, or blockages.
• Record the findings and recommend any necessary repairs or cleaning.

8. How do you repair a leaking joint between a sewer lateral and main line?

To repair a leaking joint, I would first excavate the area around the joint to expose it. Then, I would clean the joint surfaces and apply a new gasket or seal. If the leak is due to a damaged pipe, I would cut out the damaged section and replace it with a new piece of pipe.

9. What are the different methods used to clean sewer laterals?

Mechanical Cleaning:

• Using a power auger to break up and remove blockages.

Chemical Cleaning:

• Pouring chemical solutions into the lateral to dissolve grease and debris.

Hydro Jetting:

• Using a high-pressure water jet to blast away blockages.

10. How do you troubleshoot and resolve a sewage backup in a building?

• Check the sewer cleanouts inside and outside the building for blockages.
• Inspect the lateral for any leaks or damage.
• Contact the city or sewer authority to check for blockages in the main sewer line.
