Abstract

L'invention concerne la séparation de l'huile et de l'eau de pluie s'écoulant d'un parking ou d'une surface cimentée d'une station d'essence. Un réservoir d'entrée (12) reçoit l'eau de ruissellement. Quand l'eau de ruissellement entre dans ce réservoir avec un débit faible, l'eau ou/et l'huile de surface dans le réservoir d'entrée s'écoulent vers le réservoir de séparation principal (21) où l'huile flotte sur de l'eau propre. Cette eau propre est dirigée vers une conduite de sortie (18) qui amène l'eau non polluée vers des égouts urbains ou vers une rivière. Lorsque le débit d'entrée augmente à une valeur moyenne, une conduite ayant la forme d'un L renversé (14) amène l'eau propre du réservoir d'entrée (12) vers la conduite de sortie (18). Quand le débit d'entrée devient très important, par exemple en cas d'une pluie importante, le niveau du fluide dans le réservoir d'entrée (12) monte jusqu'à un niveau où il y a un débordement direct vers la conduite de sortie (18).
