What kind of sewer receives wastewater from two or more branch sewers?

Explanation:
In a sewer system, sewers are arranged in a hierarchy: branch sewers feed into sub-main lines, which feed into main (trunk) sewers, and the largest lines are interceptors that carry flows toward treatment. A main sewer is the line that collects wastewater from multiple sub-mains, which themselves carry flows from several branch sewers. So it receives wastewater from two or more branch sewers (even if indirectly through sub-mains), making it the correct choice. Branch sewers serve a small area or building, sub-mains collect from several branches, and interceptors take flow from main sewers toward the treatment point.
