100 Bung Sewer Interview Questions and Answers

  1. What is a bung sewer?

    • Answer: A bung sewer is a type of sewer system where wastewater is conveyed through a relatively small diameter pipe, often without the use of gravity. It may involve pumping or other methods to move wastewater.

  2. What are the advantages of a bung sewer system?

    • Answer: Advantages can include smaller footprint, potentially lower installation costs in certain situations (though this depends heavily on the specific context), and suitability for areas with challenging topography.

  3. What are the disadvantages of a bung sewer system?

    • Answer: Disadvantages include potential for blockages due to smaller diameter, higher maintenance requirements (especially related to pumping systems), and potential for higher energy consumption compared to gravity-fed systems.

  4. What materials are typically used for bung sewers?

    • Answer: Common materials include PVC, HDPE, ductile iron, and concrete, depending on the specific application and local regulations.

  5. How are bung sewers cleaned and maintained?

    • Answer: Cleaning and maintenance often involves high-pressure water jetting, CCTV inspection, and regular pump maintenance/replacement. Specific procedures will vary based on the system design.

  6. What are the typical flow rates in a bung sewer?

    • Answer: Flow rates vary significantly depending on the size of the sewer, the number of connected properties, and the type of wastewater. Precise flow rates would need to be determined based on a site-specific hydraulic analysis.

  7. How are bung sewers designed?

    • Answer: Bung sewer design requires careful consideration of hydraulics, materials, access points for maintenance, and the location and capacity of pumping stations (if applicable). It usually involves detailed hydraulic modelling software.

  8. What are the common causes of blockages in bung sewers?

    • Answer: Common causes include grease buildup, improperly disposed-of items (e.g., wipes, sanitary products), root intrusion, and sediment accumulation.

  9. What safety precautions are necessary when working with bung sewers?

    • Answer: Safety precautions include wearing appropriate personal protective equipment (PPE), including respirators, gloves, and protective clothing; ensuring adequate ventilation; and following confined space entry procedures.
