A Bioretention System is a system that uses vegetation to reduce downstream flow velocities and subsequent drain sizes whilst facilitating treatment. Bio-retention systems combine various Water Sensitive Urban Design (WSUD) treatment types in one 'treatment train'. A system is designed to carry out primary and/or secondary treatment processes of stormwaters and retard flows. This retention or retardation can enable sediments to precipitate out of the water taking along with it some pollutants. The use of biological processes to 'treat' stormwater whilst facilitating conveyance and retention gives rise to the title of Bio-retention.

A Bio-Retention System is a well-vegetated, retention cell or pond designed to enhance water filtration through a specially prepared sub-surface sand filter. Bio-retention cells may be incorporated into grass or vegetated swales or may be a stand-alone treatment system. The system incorporates vegetation with medium-term stormwater retention and sub-surface filtration/infiltration.

A Box Culvert is a П-shaped reinforced concrete structure used in civil engineering works, including; drainage and road works. Box culverts are most commonly used as an alternative to drainage pipes where design constraints limit the amount of cover available, but are also used in the construction of of a range of other assets including; pedestrian underpasses.

A catch drain is a small surface channel constructed to intercept and divert runoff away from cut slopes, embankments, disturbed areas, and stockpiles.

A constructed wetlands is a shallow pool of water, characterised by extensive areas of emergent aquatic plants/macrophytes, designed to support a wide range of micro-organisms and plants associated with the breakdown and trapping of nutrients. Wetlands may be designed as permanent wet basins (perennial) or ephemeral systems.

A culvert is a conduit used to enclose a flowing body of water. It may be used to allow water to pass underneath a road, railway, or embankment for example. Culverts can be made of many different materials; steel, polyvinyl chloride (PVC) and concrete are the most common. Formerly, construction of stone culverts was common.

A drainage system is a system of gully inlets, pipes, overland flow paths, open channels, culverts and detention basins used to convey stormwater runoff to its receiving waters. In urban areas stormwater runoff volumes are typically greater than they were prior to urbanisation because of increased impervious areas within catchments. Drainage systems are designed to reduce the risk of council, community and private assets being damaged by localised flooding as a result of these increased runoff volumes.
