What is the recommended method to clear obstructions in sewers?

• A. Small blasting charges
• B. Power rodder with an auger head
• C. Lamping between manholes
• D. Using a hose from the nearest fire hydrant

Answer: (B)

The recommended method to clear obstructions in sewers is utilizing a power rodder with an auger head. This approach is effective because a power rodder is designed specifically for the task of clearing blockages in sewer lines. The auger head can efficiently grab and dislodge debris, roots, and other obstructions that may be causing a blockage. This mechanical cleaning method is powerful and can reach deep into the pipes, making it suitable for tough clogs that other methods might not effectively clear. Using a power rodder also minimizes the risk of damaging the pipes, which can happen if more aggressive methods, such as blasting charges, are employed. It’s essential to select a cleaning method that not only clears the obstruction but does so while preserving the integrity of the sewer infrastructure. In contrast, other methods mentioned, such as blasting charges, may not adequately address obstructions without risking pipe damage, while lamprishing between manholes is typically not used for clearing blockages but rather for inspections or maintenance. Using a hose from a fire hydrant is inappropriate for clearing sewer blockages, as it does not apply the necessary force to dislodge obstructions and might create additional problems in the wastewater system.
