Blue Roof Drain

Passive blue roof systems control the rate at which water drains from a rooftop through non mechanical means.

Blue roof drain.

Blue roof design is a sustainable urban drainage system suds that is ideally suited to buildings that take up the entire lot or a major percentage of it. The patented blue roof system utilises the roof construction for the attenuation of stormwater releasing it at a controlled rate in the period following the storm. The suitability of a blue roof and potential design options for a given building are determined based on various factors including structural capacity roof type and slope local climate and local regulatory requirements. Blue roofs also known as controlled flow roof drain systems are detention stormwater management practices smps that provide temporary storage and slow release of rainwater on a rooftop.

Blue roof systems are an effective practice for controlling runoff from buildings with flat or mildly sloped roof surfaces. The bauderblue roof system is a sustainable drainage method designed to attenuate and manage stormwater on a flat roof over a 24 hour period via a restrictive flow outlet. Instead of forcing rainwater to flow directly into an underground drainage system surface water is collected and stored and if necessary cleaned before it is used or released back into. Cavidrain building abg cavidrain drainage geocomposite is a preformed cavity drainage system designed to relieve water penetration from basements and buried structures.
