Slotted Drains

Slotted drains are semi-underground drainage conduits with a cavity inside and a slot to the surface. The slot collects storm water that is drained away by means of the cavity within the Slotted Drain. Placed end-to-end, the cavities line up and work like a pipe.

Advantages of Slotted Drains:

  • It is laid flush with the surface and, as opposed to an open channel or dish, causes no disturbance to wheel or pedestrian movement.
  • Very effective and even drainage by means of the long slot.
  • No grids, catch pits or separate storm water pipes.
  • No clogging up with large objects entering the pipe.
