Precast concrete attenuation systems provide the ideal solution for gravity storm water attenuation in line with current SuDS guidelines. Stanton Bonna offer a comprehensive range of circular, elliptical and rectangular tanks tailored to specific site requirements.
Our Attenuation Systems can be manufactured with a variety of fittings including blank ends, access points, manifold pipes and flow control units together with headwalls enabling discharge into ponds or swales.
Stanton Bonna will also provide assistance with the design, specification and installation of attenuation tanks.
Elliptical pipes can be designed for both horizontal or vertical installation and are especially useful where the space and cover depths are limited and in areas which are subject to vehicular trafficking.
Our Attenuation Systems are available in a wide range of sizes:
- Up to 2400mm Circular
- Up to 2650 x 1500mm Elliptical
- Small rectangular up to 1500 x 700mm (Compact Culverts)
- Medium rectangular up to 2000 x 1000mm with integrated dry weather flow channel (AquaCulverts)
- Medium to large rectangular up to 6000 x 3000mm (Box Culverts)
Other sizes may be available on request, contact us for further information.
