In my basement I have a pipe that is around 8" below the floor that drains into my sump pit but I have no idea where the pipe goes under the floor or where it actually drains from. It trickles or even a small stream after a good rain so I know it works but I am trying to figure out why its there and where it is draining from. It is angled so that it goes almost corner to corner across the diameter of my basement. Can anyone please tell me what it is actually draining and why?

thanks
