AquaDuct is a culvert flume that is used to control water and prevent erosion around culvert outflows.

AquaDuct is an innovative low cost solution to remove water away from the end of culverts and to prevent erosion around and under culverts. AquaDuct can be installed in long lengths where access makes it difficult to channel water in a controlled way to the base of steep slopes.

AquaDuct is available in a single and double cleat. The double cleat adds strength and secures the product on both sides of the flume. This is recommended for longer or larger diameter flumes.

AquaDuct has a unique double reinforced zone at the top to reduce tearing from pipe abrasion. Stainless steel straps are also available for clamping to the pipe.
