Roots can enter collection systems through

• A. Air gaps
• B. Manhole covers
• C. Pipe cracks
• D. Inflatable dams

Answer: (C)

Roots invade collection systems where moisture from the surrounding soil seeps into the pipe, creating a welcoming pathway for growth. The direct and common entry point is cracks and joints in the pipes themselves, where roots can push inside and establish a foothold, eventually causing blockages and damage. Air gaps are safety features designed to prevent backflow, not routes for root intrusion. Manhole covers are entry points for access and maintenance, but roots typically enter through damaged pipe sections rather than the cover itself. Inflatable dams are used to isolate sections of the system and do not create pathways for roots.
