Weeping wall

A weeping wall comprising:

• a wall body including a magnetic material layer extending along at least a portion of a flow surface receiving a continuous flow of flowable substance running downwardly thereon;
• a flowable substance inlet positioned at an upper end of the flow surface and releasing a flow of the flowable substance;
• a flowable substance outlet positioned at a lower end of the flow surface and receiving a flow of the flowable substance, the flowable substance outlet being in fluid communication with a reservoir collecting and storing the flowable substance;
• a pump constantly moving the flowable substance from the reservoir to the flowable substance inlet;
• at least one mobile deflector movably engaged to the flow surface using a magnet and projecting therefrom, each one of the at least one mobile deflector being sized and shaped to disrupt the flow of flowable substance dripping down the flow surface and being magnetically held in place on the flow surface to be selectively movable relative to the flow surface to modify a flow path of the flowable substance on the flow surface;
• and
• a deflector repositioning system cooperating with at least one of the at least one mobile deflector mounted to the flow surface, to move the at least one of the at least one mobile deflector on the flow surface.
