Blue roof system designed with enhanced in-built water storage capacity and controlled discharge.
ABG blueroof provides stormwater attenuation capacity at source within the green, ballasted or paved roof, or podium deck construction of a development.
It comprises a combined drainage and attenuation void within the roof structure and a series of roof restrictor chambers which sit over each roof outlet. The chambers are designed to release the attenuated water at a controlled discharge rate as permitted in the planning consent of the site. Designing a blue roof in this way allows storage capacities suitable for up to a one in 100 year storm event, plus an allowance (typically 30%) for the effects of climate change, to be achieved. The water is filtered several times as it passes through the system removing suspended solids thus improving the quality of water at discharge. This stored water, as with a ‘traditional’ storage system, can be released at a controlled rate or even used as grey water or irrigation for the vegetation across the development.
The blueroof system consists of two key components:
