Attenuation

Storm attenuation systems are essential for managing surface water runoff and reducing the risk of flooding in both residential and commercial developments. At Cotterill Civils, our Storm Attenuation Collection features a comprehensive range of high-quality solutions designed to control, store, and gradually release excess rainwater into drainage systems at a safe rate. Our range includes attenuation crates, soakaway systems, geotextile membranes, and associated fittings, all engineered to meet modern drainage standards and SuDS (Sustainable Drainage Systems) requirements.
