Which term refers to groundwater entering through leaks in pipes and joints?

Explanation:
Groundwater entering through leaks in pipes and joints is infiltration. It happens when water from the surrounding soil seeps into the sewer through cracks, gaps, or faulty joints in the pipe, adding flow inside the system, especially after wet weather. This differs from inflow, which is surface water entering through direct openings like manholes or drains; runoff is rainwater that runs off the surface into the system rather than seeping through pipe walls; and backflow is water reversing direction and entering the system from downstream due to pressure issues. Infiltration specifically describes groundwater seeping into the pipes through leaks.
