paysagement

outlet (drainage outlet)

In French: exutoire

Definition

The place where water from a lot, a swale or a drain is released without causing damage: the street, a ditch, a grassed or planted area that absorbs it, or a dry well. Without an outlet, a drain or swale fills up and does nothing.

Also called

  • discharge point
  • daylight outlet

Other names in French

  • point de rejet
