This is Session #7 of the 2025 ‘Stormwater Fundamental’ series, and focusses on high flow (Filterra) bioretention. Filterra bioretention system is very similar to ‘conventional’ biofiltration systems (using ‘sandy loam’ filter media). A key difference, however, is that Filterra bioretention systems utilise a filter media blend that can treat flows at a significantly higher flow rate than typical biofiltration filter media. Filterra bioretention systems can also achieve local stormwater pollution reduction targets with significantly less area (typically 3 to 5 times less area) relative to conventional biofiltration systems. This session will provide an overview of high flow (Filterra) bioretention systems, including how they work, case studies, performance monitoring data, government approvals, and maintenance requirements.
The 60-minute session will include a short presentation by Ocean Protect’s Brad Dalrymple and Harout Tcherkezian, followed by Q&A with attendees. A certificate of CPD can be provided to attendees upon request. The 2025 Stormwater Fundamental Series is proudly brought to you by Ocean Protect.
