Sample interview questions: Can you explain the process you follow for sewer line inspections and repairs?
Sample answer:
For sewer line inspections, the process typically involves a few important steps. Firstly, we use specialized equipment such as sewer cameras to visually inspect the inside of the sewer lines. These cameras are attached to a long, flexible cable that is inserted into the sewer line, allowing us to see any potential issues or blockages.
During the inspection, we carefully navigate the camera through the sewer lines, looking for signs of damage, cracks, tree root intrusions, or any other problems that could affect the proper functioning of the sewer system. The camera provides real-time video footage, which helps us accurately identify the source and extent of the issue.
Once the inspection is complete, we analyze the recorded footage and determine the appropriate course of action. If we identify any blockages, we may recommend using hydro-jetting, a process in which high-pressure water is used to clear out debris and buildup within the sewer lines. This helps restore proper flow and functionality to the system.
If we discover any damaged or deteriorated sections of the sewer line, we may recommend repairs or replacements. This could involve digging up and replacing the affected section of the pipe, or in some cases, we may use trenchless repair techniques such as pipe lining or pipe bursting. These methods minimize the need for extensive excavation and can help save time and costs…. Read full answer
