Tilting Weirs
Aquatic Control Engineering (ACE) supplies and installs high-performance AQUIKO Tilting Weirs — engineered for precise water-level control in rivers, drainage channels, wetlands, outfalls and flood-management structures. Built from high-quality stainless steel and designed for long service life, AQUIKO Tilting Weirs offer reliable, adjustable flow regulation with manual, electric or hydraulic actuation.
ACE provides complete support including design, sizing, manufacture, installation, automation integration and project management — delivering a fully engineered water-control solution tailored to your site.
Accurate Water-Level Control
Tilting weirs regulate water levels by rotating a stainless-steel flap plate around a fixed pivot. This allows operators to adjust upstream water depth with precision — essential for drainage systems, natural waterways, fisheries, wetlands, abstraction points and SUDS control. AQUIKO designs ensure smooth, predictable movement and excellent sealing, supporting accurate hydraulic performance across a wide range of flows.
Flexible Actuation Options
AQUIKO Tilting Weirs can be configured with:
Manual handwheel or lever
Electric actuators (with SCADA or telemetry compatibility)
Hydraulic actuation for remote or high-load installations
This allows seamless integration into new or existing water-control networks, enabling anything from simple manual systems to fully automated water-level management.
Robust Stainless-Steel Construction
All AQUIKO Tilting Weirs are designed and built using stainless steel 304 or 316 for maximum corrosion resistance and long-term durability in exposed or submerged environments. Reinforced frames and high-grade pivots guarantee reliable operation, even under variable water pressures or heavy debris loads.
About Tilting Weirs
Tilting weirs are widely used where adjustable upstream water control is required. Unlike fixed weirs or penstocks, tilting weirs allow operators to adapt to changing environmental conditions — maintaining fish passage depths, regulating habitat levels, or controlling flows during storm events.
AQUIKO’s design combines robust engineering, smooth operation and simple maintenance, making them suitable for rural drainage boards, waterways, utility sites, civil engineering projects and environmental applications.

More About Tilting Weirs
Tilting weirs are essential water-control assets for managing upstream levels, regulating flows and protecting downstream infrastructure across drainage districts, IDB networks, river systems and nature-based sites. AQUIKO Tilting Weirs are engineered for performance, using stainless-steel construction, reinforced frames and precision pivots to ensure reliable hydraulic behaviour in fluctuating conditions.
These systems are widely deployed in drainage channels, watercourses, culverts, abstraction points, wetlands, fisheries and flood-management structures. They allow operators to respond dynamically to heavy rainfall, drought conditions or seasonal habitat requirements. When paired with electric actuators, they provide stable automated regulation — maintaining water depth within tight tolerances, supporting habitat creation and preventing overtopping or channel erosion.
Tilting weirs are also beneficial for fish migration, as controlled upstream levels can help maintain passable depths during critical migration periods. Their smooth, open flow path reduces turbulence, making them well suited to environmentally sensitive sites.
ACE’s integration expertise covers design, fabrication, installation, automation, and long-term maintenance, ensuring your water-level management system performs reliably over decades.
