Once a discharge line is run outside, it will go away from the backfilled area of the foundation and will run downhill to prevent the water from running back into the sump pit. This leads the water away from the home without adding it back to the foundation to be pumped out once more. Many homeowners run their discharge lines into nearby streams or other similar areas.

You can see the discharge was directed far away from the house so the water will not come back to cause this homeowner more problems.
