"God is in the details"

When French novelist Gustave Flaubert popularised the saying "God is in the details", it is unlikely that he was referencing stormwater attenuation in nineteenth century Rouen. However, it is exactly this approach that makes ADS StormTech the world's most popular proprietary stormwater attenuation system - every component is designed and engineered to perform at optimum efficiency. "God is in the details", indeed.

For example, StormTech's robust continuous true elliptical arch design is an important function of structural performance. The chambers effectively transfer loads to the surrounding embedment, shaping the stone into structural arches with load bearing columns which provide the required live load and long-term dead load safety factors. This makes StormTech more adaptable than other systems, as it's the stone that transmits the majority of the load - not the chamber. This makes it easy to optimise systems for all conditions, including low cover depths and deep installations.

People might assume that the 'StormTech Gold' colour is a marketing quirk or an arbitrary design choice of little relevance to performance. Not so. 'StormTech Gold' is specifically chosen to improve performance. Dark colours absorb radiated heat. Lighter colours, including 'StormTech Gold', tend to reflect this heat, thus reducing the increase in temperature, meaning that the stiffness of the material and other properties remain within design limits and that the structural integrity of the chambers is preserved. The bright colour also makes inspection easier as it provides a light background to help see inside the chamber.

StormTech chambers are injection moulded to guarantee uniform wall thickness and repeatable quality. These are essential properties to ensure that a reliable product consistent to the original design will provide structural integrity over a long service life. Other forms of manufacturing, for example vacuum forming, use lower cost production methods, but do not provide such consistent product quality. The efficacy of StormTech's manufacturing process is shown by the fact that the system is both BBA approved and compliant with ASTM F2787, F2418 and F2922.
