This brochure provides information on biofilters and where they can be used in the water sensitive urban design process.
Biofilters, also known as biofiltration systems, bioretention systems and rain gardens, are excavated basins or trenches that are filled with porous filter media and planted with specially selected vegetation to remove pollutants from stormwater runoff. These use natural and physical processes to treat stormwater. Biofilters have very flexible configurations and climate, soil, and groundwater requirements.
