Roof attenuation for blue/ green roof applications.
Complete roof water attenuation system for blue, green and blue/ green roofs. It enables engineers to create a drainage platform which gives architects the design flexibility required to create imaginative, multi-functional open green spaces at the roof or podium level.
Comprising a shallow, high-strength, adjustable geo-cellular storage void and roof outlet flow control system, it is fully compatible with ACO roof outlets, downpipes and surface water drainage systems to provide a complete sustainable drainage system (SuDS).
Complete system includes:
ACO Blue Roof Flow Restrictor:
When combined with the ACO Blue Roof Flow Restrictor, the units can store rainwater at source to control surface water run-off. The system can also permanently store a percentage of the captured water for use in passive irrigation systems. Manufactured from corrosion-resistant 1.4301 (304) grade stainless steel. A coded solid cover (with vent) ensures the restrictor position is easily identified and prevents debris from potentially blocking the outlet.
The design of the restrictor is individually tailored to suit the site-specific requirement of each roof. Carried out to BS EN 12056-3 or attenuation sizing principles. ACO design services need to know:
