e/Leach drain

Information
has gloss	eng: Septic drain fields are used to remove contaminants and impurities from the liquid that emerges from the septic tank. Another term for this is a leach field or leach drain. A septic tank, the septic drain field, and the associated piping compose a complete septic system. The septic drain field is effective for disposal of organic materials readily catabolized by a microbial ecosystem. The drain field typically consists of an arrangement of trenches containing perforated pipes and porous material (often gravel) covered by a layer of soil to prevent animals and surface runoff from reaching the wastewater distributed within those trenches. Primary design considerations are hydraulic for the volume of wastewater requiring disposal and catabolic for the long-term biochemical oxygen demand of that wastewater.

Meaning
French
has gloss	fra: Un lit filtrant est un élément constitutif de la chaîne dassainissement non collectif. Situé en aval de la fosse septique, son rôle est de poursuivre le nettoyage des eaux par une action filtrante. Ce traitement biologique se fait par des bactéries aérobies (à la différence du prétraitement dans la fosse toutes eaux qui fait intervenir des bactéries anaérobies) qui se développent dans le sable disposé sous les drains de répartitions de leffluent prétraité sortant de la fosse.
lexicalization	fra: lit filtrant
