Tilting weirs


  • Quick and Easy to install
  • Lightweight yet robust
  • Ultimate variation of weir level
  • Virtually maintenance free


ACE Tilting weirs offer ultimate variability and precision in water level management. Therefore, making them ideal either for manual or automated applications. Commonly used in conservation areas, land drainage and large river systems. ACE tilting weirs have a wide range of applications, all with safety and ease of operation. Similarly low requirement for maintenance are part of their core design. The weirs operate by adjusting a weir plate between vertical and horizontal, allowing any position in between to be maintained, and debris such as branches and weed to float straight over.


The tilting weirs are manufactured in HDPE and Stainless Steel 316L. Therefore, making them lightweight for ease of handling and installation, without compromising strength. In addition to this, ACE offer a beamless version for watercourses that are used by canoes or a lot of floating debris. The KSU range of pre-cast units to make installation even easier!
