Althon have launched a Headwall Design Tool that enables you to specify the headwall you require with associated factory fitted accessories.
They have produced a Headwall Design Request Form where you fill out as much information as possible. Althon will then send you a CAD & PDF drawing of your chosen headwall and will liaise with you to further refine the design to suit your specific requirements if required.
Headwall accessories include but are not limited to flap valves, penstocks, cascade panels, dissipation blocks, V notch weirs, handrails, gates & ladders.
