Top 10 Questions for Public Works Technician Interview

1. Describe the process of inspecting and evaluating wastewater treatment systems?

The process of inspecting and evaluating wastewater treatment systems involves several key steps:

• Visual Inspection: Inspecting the physical components of the system, including pumps, tanks, pipes, and other equipment, for any signs of damage, leaks, or corrosion.
• Sampling and Testing: Collecting samples of wastewater at various points in the treatment process and analyzing them for parameters such as pH, dissolved oxygen, and the presence of pollutants.
• Flow Monitoring: Measuring the flow rate and volume of wastewater treated to ensure the system is operating within its design capacity.
• Data Analysis and Reporting: Compiling and interpreting the inspection and testing data to assess the system’s performance, identify any issues, and make recommendations for maintenance or improvements.

2. How do you troubleshoot and repair common issues in water distribution systems?

Pumping Issues

• Check for clogged impellers or worn seals.
• Inspect electrical connections and ensure proper voltage.

Pipe Leaks

• Identify the location of the leak using acoustic listening devices.
