WEIR HEADWALL

Weir headwalls will, by adding weir boards, control water levels and discharge to maintain
water levels for agricultural purposes. They also aid in flood control and other water
management applications.

The 3, 4 and 5 Series weir headwalls are based on the Linear Shell design to accommodate
the use of weir boards-

Weir boards are fabricated from recyclable plastic wood providing long life and an
environmentally friendly installation.
