Italian to English Tech/Engineering Automation & Robotics

This phrase comes from a confidential document so I'll just explain the context. The text relates to warehouse automation and specifically this phrase related to picking islands where items are picked and put onto pallets. The island has 2 stations for source pallets, 4 for order pallets, a line to stack empty pallets and then:

Si prevede inoltre un ramo per l’evacuazione delle falde

The term isn't used again in the text so there is no other context.

Thanks
