After a storm, a tile riser drains a pothole in a wheat field. Tile risers are perforated pipes extending a foot or more above the soil. Water flows into the holes in the pipe and then typically flows unimpeded and unfiltered into subsurface drains and eventually into streams, causing pollution. An ARS scientist has shown that a blind inlet provides a solution.
