A channel, encased in concrete, enables the discharge of liquids that are separated from the solid elements. Made from anti-wear PVC, it is equipped with a shell circulating inside the conduit to prevent any obstruction.
The upper opening slot is 5 mm and the slope of the channel on the edge is 8%. Since the effluents can be recovered beyond the recovery channel, the depth of the channel is significantly reduced, thus reducing the volume of concrete necessary.
