DURAWEIR is a manually controlled weir installed on FLOLINE 3-W culvert to regulate water flow and level across the culvert in irrigation and drainage channels particulary at oil palm plantation. The weir can help maintain moisture in peatland.

The weir can be adjusted to two (DW600, DW750, DW900) or three (DW1200, DW1500) different water levels by manually adding/removing weir panels on the DURAWEIR.

The weir panels are made from reinforced HDPE sheets and specially designed to be lightweight and easy to handle, while ensuring good sealing between the panels.
