A waterproof membrane is often installed on the outside of the basement wall and the system also requires putting in a buried sump pump where water will collect and then be pumped to the surface.
As this happens a void opens up that allows water from outside seep in next to the pipe.
Many times shifting soil or a house settling can create a gap around the pipe and an escape route for water before it reaches the foundation drain pipe.
