You’re weighing up a conventional bioretention system or a Filterra® High-Flow Bioretention System for your next project. Here’s what might help you decide.
Compare the pair…
🌱 Same species, same street, same supplier, planted the same day.
🌱 The tree on the left, planted in natural soil. On the right, planted within a Filterra bioretention system.
🌱 Each endured dry conditions – with only minimal rain over the past four months.
The plant survival rate is much better for Filterra bioretention systems.
Why the difference?
🌳 75mm of hardwood mulch over Filterra® media vs no mulch.
💧 Filterra filter media is great at retaining moisture.
🌧️ The small rain events that have occurred helped water the tree within the Filterra bioretention system.
About Filterra® High-Flow Bioretention Technology
Filterra® is a high-flow bioretention technology that is designed to remove high pollutant loads.
Small but mighty, Filterra bioretention is also suited for tight urban spaces – like landscaped areas, parking lots and streetscapes – while delivering better resilience and performance than ‘conventional’ bioretention systems.
Filterra bioretention may be small, but it delivers high flow capacity and strong pollution removal effectively, thanks to its specially designed filter media. In addition to supporting system performance, the filter media retains moisture in between rain events, allowing the vegetation and system health to thrive during dry periods, which is what you see in the picture on the right.
For this project, Ocean Protect is grateful to Urban Renew for their key role in establishing the Filterra bioretention systems, City of Charles Sturt, and our team who made it all work seamlessly behind the scenes.
