Bioretention systems, also known as biofiltration systems, biofilter or rain gardens, is a common stormwater mitigation measure. It utilises a low energy consumption treatment technology to increase water quality and reduce peak discharge. A typical bioretention system can be configured as a basin or a longer narrower vegetated swale overlaying a porous filter medium with a drainage pipe at the
bottom. Surface runoff is diverted from the kerb or pipe into the biofiltration system, where it physically filtered through dense vegetation and temporarily ponds on
the surface of planting media that acts as a filter before being slowly infiltrated vertically downwards through the media. Depending on the design, treated water— the effluents—is either exfiltrated into the underlying or surrounding soils, or collected in the underdrain system—subsoil perforated drain—to downstream waterways or receiving waterbodies. The system varies in size and receives and treats runoff from a variety of drainage areas within a land development site. They can be installed in parks, roadside planting verges, parking lot islands, commercial areas, civic squares and other unused areas.
