Épandage souterrain à faible profondeur. Ce mode d’épuration nécessite un sol perméable [...] les terrains trop perméables ne peuvent être retenus [...] Il est prudent d’effectuer au préalable un essai de perméabilité. À cet effet, une fosse d’expérience est creusée jusqu'au niveau supérieur de la couche filtrante et remplie d’eau sur 0, 15 m de hauteur. La charge admissible sur la surface filtrante est définie en fonction du temps que demande l'eau pour s’abaisser d’un centimètre dans le sol préalablement imbibé [...] 4, record 1, French, - essai%20de%20perm%C3%A9abilit%C3%A9

Mesure en place du coefficient de perméabilité [...] Pour calculer le débit d’assèchement d’une fouille ou celui d’un drain, il est nécessaire de connaître la valeur du coefficient de perméabilité [...] La mesure peut s’effectuer en laboratoire [...] mais les résultats obtenus n’ont généralement pas une signification précise [...] Il est donc nécessaire de faire la mesure en place. 3, record 1, French, - essai%20de%20perm%C3%A9abilit%C3%A9
