Grease in sewers is mechanically removed by which method?

Explanation:
Grease removal in sewer pipes relies on breaking the greasy film off the pipe wall and flushing it away. A high-pressure water jet delivers a powerful stream that scours the interior surface, loosening the grease and carrying it downstream in suspension. This combination of cleaning the wall and moving the loosened material out of the system makes high-pressure jets the most effective method for grease deposits. Mechanical rodding can push through or break up some obstructions but doesn’t clean the wall surface as thoroughly, and sawing isn’t practical inside live sewer lines.
