Design and Supply of Modular Tilting Weir / Headwall Solutions in conjunction with Aquatic Control Engineering (ACE)

When Aquatic Control Engineering (ACE), a company specialising in mechanical solutions for flood defences and biodiversity conservation, faced significant complexity and costs with developing bespoke designs for water control equipment installations, they turned to JKH for help developing a more standardised solution.

Recognising the need for a more efficient and cost-effective solution, ACE sought JKH’s expertise to develop a modular precast concrete headwall system that could address their needs.

The solution

JKH Ltd collaborated closely with ACE to design a groundbreaking modular tilting weir headwall solution. Utilising their extensive expertise in precast concrete solutions, the team at JKH conducted Design for Manufacturing (DFM) analysis to revise the initial designs to ensure cost effective manufacturing as well as ease of installation.

This system was meticulously developed to comprise a simple panel assembly design to offer adaptability for various water level management situations, as well as the flexibility to align with lift capacity and access limitations presented by even the most demanding of sites.

The resulting modular design allows for multiple options and accessories, making it suitable for a range of uses including habitat creation, peat regeneration schemes, water level management, housing developments, and general drainage.

Key Features

1. Modularity: The system’s modular nature provides the flexibility needed to tailor each installation to specific project requirements, it also aids installations in difficult and inaccessible locations
2. Lightweight Construction: The lightweight design reduces lifting demands and minimises ground pressure loadings, enhancing ease of installation and reducing environmental impact.
3. Environmental Consciousness: The pre-cast approach curtails material use and minimises pollution risks associated with in-situ poured concrete methods, promoting sustainability.
4. Seamless Installation: Components are fabricated to minimise labour requirements, ensuring projects stay on schedule without compromising quality.
5. Hardware Options: The system can be outfitted with various hardware options, including tilting weirs, stop logs, floating tilting weirs, screens, flap valves, penstocks, and access options, allowing for extensive customisation.

The Results

The collaboration between ACE and JKH Ltd resulted in a versatile and efficient modular headwall solution that significantly reduced both installation costs and environmental impacts.

The system’s adaptability and ease of installation have proven to be a winning formula for aquatic engineers, enabling them to achieve both efficiency and excellence in their projects.
