These guidelines provide practical advice on designing stormwater biofiltration systems to treat runoff in urban areas. Biofilters use vegetation, soils and filtration processes to remove pollutants from stormwater before it enters waterways.
The guidelines cover key design considerations including sizing, filter media, hydraulic performance, vegetation selection and system configuration. They also outline how biofilters function, common design approaches, and factors that influence treatment performance and long-term operation.
Stormwater biofilters play an important role in improving water quality, reducing pollution, and supporting water sensitive urban design outcomes. Well-designed systems can also contribute to greener streetscapes, urban cooling and more resilient cities.
This resource is useful for engineers, planners, designers and council staff involved in stormwater management, urban design and infrastructure projects.
